Mr Vegas and Videoslots are associated with Siru Mobile, while MrQ and Duelz are associated with Fonix; cashier options can differ.
Where Siru Mobile Is Still Accepted
Siru Mobile remains available at a limited number of UK-facing casino operators. The named operators associated with Siru Mobile are Mr Vegas and Videoslots.
That list should not be confused with casinos offering other Pay by Phone services. MrQ and Duelz are associated with Fonix, not Siru Mobile. Fonix and Siru Mobile both belong to the wider Pay by Phone category, but acceptance of one does not establish acceptance of the other. A cashier showing a mobile-payment option is therefore not enough to assume that a Siru Mobile number will work.
The distinction matters because the UK market has been moving away from Boku. Since 2023, operators have replaced Boku with alternatives such as Fonix and Siru Mobile, or removed Pay by Phone deposits altogether. The result is a much shorter list than the broad collections of Boku casinos that appeared in older payment guides. A casino may still be described online as accepting mobile payments while its current cashier supports only one particular provider.
The confirmed Siru Mobile options
The operators connected with Siru Mobile are:
- Mr Vegas
- Videoslots
This is a payment-method identification, not a ranking. It also does not establish that every account, mobile plan or registration route will produce the same cashier options. Payment availability can change, so the relevant question is whether Siru Mobile is displayed by the operator at the point of deposit.
A specialist casino review identifies Mr Vegas and Videoslots as accepting Siru Mobile, while placing MrQ and Duelz under Fonix. That separation is important: it prevents the common error of treating every Pay by Phone label as a Siru Mobile facility. It also explains why lists headed “Siru Mobile casinos” can contain operators that belong to a different payment network.
Why Boku lists are broader
Boku has historically appeared across a larger group of casino brands, although the number of UKGC-licensed casinos retaining it has been shrinking since 2023. A specialist review associates Boku deposits with brands including BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino. That is a Boku group, not a Siru Mobile group.
The same category also includes the smaller set of direct-Boku sites identified in specialist casino coverage, such as Jackpot Mobile Casino and Peachy Games. BoyleSports was also reported as having added Boku as a UK payment choice. These references help describe the remaining Boku market, but they do not expand the Siru Mobile list.
The practical classification is therefore straightforward:
| Payment service | Operators identified with it |
|---|---|
| Siru Mobile | Mr Vegas, Videoslots |
| Fonix | MrQ, Duelz |
| Boku | A separate and shrinking group, including the brands listed above |
A Boku casino is not automatically a Siru Mobile casino, and a Fonix casino is not automatically a Boku or Siru Mobile casino. The payment provider must be checked separately for each operator.
The UK licensing requirement
Payment acceptance and gambling regulation are separate checks. The UK Gambling Commission is the regulator for commercial gambling in Great Britain and covers remote gambling offered to consumers there, even when the operator’s key equipment is located elsewhere. It issues operating licences to gambling businesses and personal licences to individuals working in relevant operating roles.
A legal online casino serving Great Britain must hold the appropriate current Gambling Commission operating licence. The Gambling Act 2005 provides the legislative framework for gambling in England, Wales and Scotland, while Northern Ireland has a separate legal framework. Accordingly, a casino’s willingness to process a Siru Mobile deposit says nothing by itself about whether the operator is authorised for the relevant British market.
The licence number should be checked on the UK Gambling Commission’s public register before any deposit is made. The register is the useful test; a payment logo, an old review, or a page describing a casino as UK-friendly is not a substitute. Operators can change their payment panels, and specialist reviews can remain online after a cashier has changed.
The same check applies to Mr Vegas and Videoslots. Their association with Siru Mobile identifies the payment route reported for those operators; it is not a licence endorsement and does not remove the need to confirm the operator’s current UKGC status. The payment method narrows the search. The licence determines whether the casino is authorised to offer remote gambling to customers in Great Britain.

Siru Mobile and Other Pay-by-Phone Casino Deposits
Siru Mobile sits within a narrower group of Pay by Phone methods now used by some UK casino operators. It is not another name for Boku, and a casino that displays one of these payment options should not be assumed to accept the others. Payment availability belongs to the individual operator’s cashier.
The confirmed Siru Mobile options are Mr Vegas and Videoslots. Fonix is used by MrQ and Duelz. These are separate operator-and-payment-method combinations: Mr Vegas and Videoslots are the Siru Mobile examples, while MrQ and Duelz are the Fonix examples. That distinction matters because the presence of a Pay by Phone logo does not establish which service processes the deposit.
A specialist review describes a wider change in the UK market since 2023. Operators have been moving away from Boku, with some replacing it with Fonix or Siru Mobile and others removing Pay by Phone deposits completely. The direction is therefore not a simple switch from one universal service to another. It is a fragmented replacement process, with the available method depending on the casino and, potentially, the mobile network.
Siru Mobile, Fonix and Boku are separate methods
Siru Mobile and Fonix can be treated as alternatives to Boku at the market level, but not as interchangeable payment buttons. A casino may support one while rejecting the others. This is why a general statement that a site “accepts Pay by Phone” is not precise enough for a deposit decision. The cashier needs to show the specific service required.

The same separation applies when comparing operator groups. MrQ and Duelz are associated with Fonix, not Siru Mobile. Mr Vegas and Videoslots are associated with Siru Mobile, not Fonix. Boku remains a different route again, despite its continued appearance among the payment options at some UK-licensed casinos.
The mobile networks named in connection with Pay by Mobile and Fonix are EE, O2, Vodafone and Three. That network support does not turn the services into one product. It indicates where the relevant mobile billing or payment arrangement is supported; the casino still has to offer the chosen service in its cashier.
For a customer looking specifically for casinos that accept Siru Mobile in the UK, the practical question is therefore not whether a site accepts mobile payments in general. It is whether the cashier identifies Siru Mobile as the available method at the point of deposit. A Fonix logo answers a different question, and a Boku listing answers another.
How the Boku process differs
Boku provides a useful comparison because its deposit sequence is defined separately. At a casino cashier offering Boku, the player selects Boku, enters the intended deposit amount and supplies the mobile number to be billed. The transaction is then confirmed with a verification code sent by SMS.
That sequence describes Boku only. It should not be presented as the operating procedure for Siru Mobile or Fonix. Those services may use their own screens, prompts or confirmation arrangements, and the named payment method in the cashier is the relevant indicator.
Boku deposit process
At a casino cashier offering Boku, the player selects Boku, enters the intended deposit amount and supplies the mobile number to be billed. The transaction is then confirmed with a verification code sent by SMS.
Boku charges the deposit through the mobile network arrangement. Depending on the type of mobile plan, the amount can be placed on a phone bill or taken from prepaid credit. It is therefore a card-free and bank-account-free route, but it remains tied to the mobile account rather than becoming a casino wallet balance supplied by the network.
The distinction is also commercial. Boku has been used as a deposit method at operators including BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino. A specialist review identifies Jackpot Mobile Casino and Peachy Games among the remaining direct-Boku sites. These names describe Boku availability, not Siru Mobile availability, and payment menus can change as operators revise their arrangements.
BoyleSports has also been described as adding Boku to its cashier as a UK payment option. That detail still belongs to the Boku category. It cannot be used to infer that BoyleSports accepts Siru Mobile or Fonix.
What to check before choosing a method
The payment method should be checked at the same time as the operator’s regulatory position. Remote gambling offered to consumers in Great Britain requires the relevant UK Gambling Commission licence, regardless of where the operator or its technical equipment is based. The Commission issues operating licences to gambling businesses, and a current licence should be checked on its public register before any deposit is made.
A payment service does not provide the licence. Siru Mobile, Fonix and Boku are deposit routes; they are not substitutes for the operator’s legal authorisation. Nor does support from EE, O2, Vodafone or Three confirm that a particular casino is licensed or that a particular cashier will accept every Pay by Phone service.

The same checking principle applies when a casino advertises itself as accepting Boku but the intended deposit method is Siru Mobile. The relevant evidence is the live cashier entry for Siru Mobile, not a general page about mobile payments and not an old list of Boku casinos. A casino can retain one method after withdrawing another.
This leaves a precise comparison rather than a single “best” Pay by Phone category. Mr Vegas and Videoslots are the confirmed Siru Mobile choices; MrQ and Duelz are the confirmed Fonix choices; Boku belongs to the older and shrinking group of direct-Boku arrangements. The services overlap in purpose, but the cashier determines which one is actually available.
Using Siru Mobile for Online Slot Play
Siru Mobile is a payment route, not a slot catalogue. The distinction matters because a casino can support Siru Mobile in its cashier while the available games, account restrictions and slot rules remain determined by the operator. Searching for online slots that accept Siru Mobile therefore leads to a payment question first: whether the casino permits a Siru Mobile deposit. It does not identify a special class of “Siru slots”.
A specialist casino review identifies Mr Vegas and Videoslots as operators accepting Siru Mobile. That identification is time-sensitive, so the payment option should be checked in the current cashier before an account is funded. The presence of a Siru Mobile logo on an older review, comparison page or promotional image is not enough to establish that the route remains active.
Checking a Siru Mobile site
- confirm that Siru Mobile appears as an available deposit method for the relevant UK account
- confirm that the operator holds a current UK Gambling Commission operating licence
- review the casino’s slot section on the device intended for play
- distinguish real-money play from any free-play or demo mode
- check the account controls before depositing, including the financial-limit prompt
Once a deposit is credited, the connection with slot play is straightforward. The balance is an account balance at the casino, and any slot access is governed by that casino’s platform and licence rather than by Siru Mobile itself. Siru Mobile does not determine which titles appear, how games are displayed, whether a mobile site or app is available, or which account controls apply. Those are operator-side features. A request for “Siru Mobile slots games” is therefore best treated as a request for slots at a casino that supports Siru Mobile, not as a request for games supplied by the payment service.
Checking a Siru Mobile slot site
The useful checks are separate:
- confirm that Siru Mobile appears as an available deposit method for the relevant UK account;
- confirm that the operator holds a current UK Gambling Commission operating licence;
- review the casino’s slot section on the device intended for play;
- distinguish real-money play from any free-play or demo mode;
- check the account controls before depositing, including the financial-limit prompt required for new customers.
The licence check is not decorative. Remote gambling offered to consumers in Great Britain requires the relevant Gambling Commission licence, regardless of where the operator’s equipment is located. The Commission is the regulator responsible for commercial gambling in Great Britain and issues operating licences to gambling businesses. A legitimate real-money slot site serving this market must therefore be assessed on the operator’s licence, not on the fact that it accepts a mobile-payment method.
Siru Mobile acceptance also says nothing about the quality or mathematical features of individual slots. No particular game, provider, return figure or volatility rating follows from the payment option. Claims about a “Siru Mobile slot machine” can confuse the funding mechanism with the game itself. The payment service may help place funds in the account; it does not manufacture, select or certify the slot titles.
British rules for online slots
Payment availability and game regulation are separate matters. In Britain, online slot play is subject to specific requirements:
- autoplay is prohibited;
- each online slot spin must last at least 2.5 seconds;
- the maximum stake per game cycle is £5 for customers aged 25 and over;
- the maximum stake per game cycle is £2 for customers aged 18 to 24.
The £5 limit for all adults took effect on 9 April 2025. These limits apply because the activity is online slot play in the British regulated market, not because the deposit was made through Siru Mobile. Switching to a bank card, wallet or another payment method would not remove them, and using Siru Mobile would not create additional slot permissions.
Age verification is also a condition of the account rather than of the payment brand. Operators must verify a customer’s age before allowing a deposit into a gambling account, and legal online gambling in the UK is restricted to customers aged 18 and over at a UK Gambling Commission-licensed operator. A Siru Mobile deposit cannot bypass that control.
The practical calculation is therefore simple: Siru Mobile may be the funding choice, while Mr Vegas or Videoslots supplies the account, games and regulated gambling environment. Availability of the payment method should be confirmed at the point of deposit, and slot play should then be assessed against the operator’s current licence and the British rules applying to every online slot.
UK Slot Play Rules
- autoplay is prohibited
- each online slot spin must last at least 2.5 seconds
- the maximum stake per game cycle is £5 for customers aged 25 and over
- the maximum stake per game cycle is £2 for customers aged 18 to 24
Deposit Eligibility, Minimums and Bonus Conditions
A Pay by Phone deposit is not automatically treated as a qualifying deposit for a promotion. The payment method and the bonus rules are separate conditions. A casino may accept Siru Mobile for real-money funding while excluding that transaction from a welcome offer, free spins, or another promotional calculation.
Eligibility therefore depends on the operator’s published terms, not on the fact that Siru Mobile appears in the cashier. The relevant wording may distinguish between payment methods, deposit types and promotional products. A condition can require a qualifying deposit, exclude Pay by Phone transactions, or state that only selected methods count towards a particular offer. A deposit that reaches the gambling balance can still fail the bonus condition.
A specialist casino review reports that MrQ, Duelz, Mr Vegas and Videoslots accept Pay by Phone deposits for bonus eligibility, with Siru Mobile specifically associated with Mr Vegas and Videoslots and Fonix with MrQ and Duelz. That is an operator-specific position, not a rule that transfers across the market. Payment availability and bonus eligibility can change independently, so the terms attached to the actual offer remain decisive.

Minimum deposits and no-deposit offers
A minimum-deposit promotion should be read as a qualification threshold, not as a statement about the payment method’s general minimum. The amount may apply only to the promotional offer and may need to be deposited in one qualifying transaction. It may also exclude payments made through a particular Pay by Phone service. The casino’s cashier and the bonus terms can therefore describe different conditions: one concerns whether funds can be credited, while the other concerns whether the promotion is activated.
The phrase “no-deposit” also needs precise handling. It describes an offer that does not require a deposit as its entry condition; it does not establish that Siru Mobile can be used without depositing, nor that winnings from such an offer can be withdrawn without completing the operator’s other requirements. A no-deposit free-spins offer can carry separate rules for eligibility, game use, withdrawal and expiry. “No wagering” is equally specific: it cannot be assumed merely because the offer is labelled no-deposit or because the payment method is accepted.
Before relying on a promotion, the material points to check are:
- whether Siru Mobile or another Pay by Phone method is an eligible funding method;
- whether the stated minimum must be met by a single deposit;
- whether the offer applies to existing customers, new registrations or both;
- whether free spins, bonus funds and cash winnings have separate conditions;
- whether the promotion has a wagering requirement or expressly removes one;
- whether the bonus expires before the associated conditions can be completed.
A specialist review gives an expiry period of 30 days for bonus funds and 72 hours for bonus spins. Those deadlines belong to the relevant offer and should not be generalised to every Siru Mobile promotion. Once an offer is accepted, the expiry clause matters as much as the qualifying deposit: an eligible payment can activate bonus funds that later lapse unused, while spins can disappear on their own, shorter timetable. The arithmetic is simple; the terms are where the cost sits.
Real-Money Play and Getting Winnings Out
A Pay by Phone deposit and a casino withdrawal are separate transactions. This distinction matters when a mobile payment option appears in the cashier for real-money slots or other casino games. Boku can be used to put funds into a gambling account, but it is deposit-only: casino winnings cannot be sent back to Boku.
The practical consequence is simple. An account funded through Boku needs a separate withdrawal route, such as a debit card, e-wallet or bank transfer. That method should be registered with the casino and checked for compatibility before any deposit is made. A successful deposit does not establish that the same payment channel can receive winnings. Payment systems are not obliged to perform both jobs merely because they appear beside one another in the cashier.
Withdrawals
Attention Boku and other mobile payment methods are deposit-only; casino winnings cannot be sent back to Boku.
The same discipline applies when looking for casinos accepting Siru Mobile. Siru Mobile availability should be confirmed in the operator’s current cashier, while the available withdrawal methods should be reviewed separately. Acceptance of a mobile payment option is not evidence that it supports cash-outs, and it does not remove the casino’s verification requirements. A mobile number can identify or authorise a deposit; it is not automatically a destination for gambling proceeds.
Age and account checks
UK-licensed operators must verify a customer’s age before allowing a deposit. This applies to real-money play regardless of whether the initial funding method is a bank card, wallet or Pay by Phone service. An account may therefore show a payment option while still requiring age or identity checks before money can be deposited.
The operator should also hold a current UK Gambling Commission operating licence when offering remote gambling to consumers in Great Britain. The licence number can be checked on the Commission’s public register before funds are committed. This is not a technicality: it identifies whether the casino is operating within the British regulatory framework.
What the payment route does not prove
A deposit made with Boku, or with another mobile payment service, does not prove that:
- winnings can be withdrawn through the same service;
- the account has passed age or identity verification;
- the operator will accept every available withdrawal method; or
- a mobile payment label applies to all casino products and transactions.
Withdrawal processing may also require the casino to confirm account details before releasing funds. That requirement is separate from how the account was funded. A casino cashier should therefore be assessed in two columns: the methods available for deposits and the methods available for withdrawals. For Boku, the first column can contain Boku; the second cannot.
What Boku Deposit Limits Mean in Practice
Boku limits are not one single ceiling. The amount that can be deposited depends on the individual transaction, the mobile network’s daily control and, for some accounts, the available phone balance. These rules apply to Boku; they should not be treated as limits for Siru Mobile deposits or for any other Pay by Phone service.
Transaction limit and daily limit
A specialist review gives the standard UK Boku transaction limit as £30. The same type of source says that some casinos and network operators may permit £40 or £50 in one transaction. Those higher figures are therefore conditions reported for particular arrangements, not a fixed limit that every Boku casino must provide.
The information on the transaction cap is not entirely consistent. Another version describes Boku deposits as typically limited to £10 per transaction, with a £30 daily network limit. A separate account gives £30 per day but does not specify a per-transaction ceiling. These are different descriptions of the same payment service, so the cashier and mobile operator’s response matter more than a generic figure copied into a casino comparison.
The distinction is practical:
- a transaction limit controls the amount of one payment;
- a daily limit controls the total charged through the mobile account during the relevant day;
- the casino may show the payment option, while the network operator applies the daily restriction.
A casino cashier may therefore accept Boku while rejecting a payment because the mobile account has already reached its daily allowance. Changing casinos does not necessarily remove that restriction, because the control sits with the mobile operator rather than the individual gambling site.
Amounts accepted by the cashier
A specialist review reports that Boku deposits are offered in amounts divisible by ten. The stated examples are £10, £20 and £30. This means that the available amount is shaped not only by the maximum permitted value but also by the increments presented during checkout. A requested amount outside those increments may not appear as an option even when the account has enough capacity for a larger payment.
The figures should also be read alongside the account type. Boku can charge a monthly mobile bill or deduct funds from prepaid credit. For a PAYG account, the available balance places an additional ceiling on the payment: the deposit cannot exceed the credit remaining on the phone. A nominal Boku limit is irrelevant if the balance is lower.
Boku Limits
Boku deposit amounts are often offered in increments divisible by ten, such as £10, £20, or £30.
For that reason, the amount shown in a casino cashier is only the starting point. The final approval depends on the casino’s configured options, the Boku limit applied to that account and the mobile operator’s current allowance. A Siru Mobile cashier requires separate checking rather than borrowing Boku’s figures.
Alternatives When Siru Mobile Is Unavailable
Siru Mobile is not the only Pay by Phone route associated with UK casino deposits. A specialist review identifies MrQ and Duelz as accepting Fonix, while listing Mr Vegas and Videoslots as accepting Siru Mobile. These payment arrangements are operator-specific: acceptance of Fonix does not mean that Siru Mobile will appear in the same cashier, and a casino offering Siru Mobile does not automatically offer Fonix.
Payment availability can change as operators revise their cashier options. The practical check is the deposit page at the relevant casino, followed by confirmation that the operator holds a current UK Gambling Commission operating licence. The Gambling Commission public register is the appropriate place to verify that licence before any funds are deposited. A payment logo alone is not a regulatory credential, however confidently it is displayed.
Using Boku as an indirect route
Boku provides another route where it is available at the casino and with the mobile network account. A specialist review describes a two-stage arrangement: funds are first added to Neteller using Boku, and the Neteller balance is then used at casinos that accept Neteller. This is not a direct Siru Mobile deposit. It adds a wallet between the mobile-billed payment and the casino account, so both stages must be available and accepted.
Boku charges the payment to the mobile account, either through a monthly bill or by deducting available PAYG credit. The casino must support Boku for the first transaction, and the destination casino must support Neteller for the second. Neteller acceptance alone does not establish that Boku can be used there directly.
DO
- Check the live cashier for Siru Mobile specifically
- Verify the operator’s licence on the UKGC public register
DON’T
- Assume a Pay by Phone logo means Siru Mobile is accepted
- Use a Boku method expecting it to work for withdrawals
Wallet funding also has a hard restriction in British gambling: a wallet cannot be used for gambling where its balance is funded by a credit card. UK-licensed casinos cannot accept credit cards for gambling, including credit-card funding routed through a money service business. That makes the funding source material, not an administrative detail. A Boku-funded Neteller balance follows a different route from credit-card funding, but the wallet and operator’s payment rules still govern whether the transaction is accepted.
Fonix, Siru Mobile and the Boku-to-Neteller route should therefore be treated as separate payment paths, with availability checked at each operator rather than assumed from the presence of one Pay by Phone option.
Small Deposits and Pay-by-Phone Constraints
A small deposit figure associated with Boku should not be treated as a Siru Mobile minimum. The available Boku descriptions do not establish a minimum deposit for Siru Mobile casinos, so a claimed £5 Siru Mobile deposit cannot be presented as a confirmed UK market standard. Siru Mobile acceptance and the minimum amount allowed are separate conditions, and both can depend on the operator’s cashier settings.
The Boku information is not fully consistent either. One account describes Boku as limited to about £10 per transaction and £30 per day at network level. Another gives a £30 daily limit without specifying a per-transaction ceiling. Those are materially different statements: the first limits each payment as well as the day’s total, while the second confirms only the daily figure. A specialist review also describes Boku’s standard UK transaction limit as £30, with some operators or network providers permitting £40 or £50. Since these figures come from changing commercial arrangements and conflicting descriptions, they are Boku reference points, not Siru Mobile terms.
Casinos That Accept Maestro in the UK: What to Check · WebMoney Casinos in the UK: What Boku Can Confirm
That distinction matters when assessing claims about instant deposits. Boku is described as crediting funds almost instantly after the mobile number and SMS confirmation are processed. Speed of crediting says nothing about the smallest permitted payment, the maximum accepted by a particular casino, or whether Siru Mobile is available in that cashier. A casino can therefore support a fast Pay by Phone deposit without supporting a £5 amount or Siru Mobile itself. The cashier’s current payment options and limits determine the practical position.
PAYG users face an additional restriction with Boku. A deposit cannot exceed the credit remaining on the mobile account; a payment is declined when the available balance is insufficient. This is a balance constraint, not a casino minimum. For instance, a PAYG account with less credit than the requested Boku deposit cannot complete that payment, even if the casino’s own cashier would accept the amount. A specialist review reports this PAYG condition, so it should be treated as a reported Boku limitation rather than transferred to Siru Mobile without confirmation.
The same caution applies to searches for non-GamStop Siru Mobile sites. A payment method does not establish a casino’s self-exclusion status, and a small or instant deposit description does not change that position. Payment availability, deposit size and regulatory status are separate checks.
Does Siru Mobile acceptance guarantee GamStop status?
No, Siru Mobile availability cannot be used as evidence of an operator’s position on self-exclusion or GamStop.
Is Siru Mobile a type of Boku?
No, Siru Mobile, Fonix, and Boku are separate payment methods and should be treated as different paths.
Siru Mobile and GamStop: What the Verified Information Shows
Siru Mobile payment acceptance and GamStop status are separate matters. A casino appearing to offer Siru Mobile does not, by that fact alone, show whether the operator is connected to GamStop, outside it, or subject to any particular self-exclusion arrangement. The payment method identifies how a deposit may be funded; it does not identify the operator’s position on self-exclusion.
That distinction matters when assessing descriptions such as “Siru Mobile casinos not on GamStop” or “Siru Mobile slots outside GamStop”. Siru Mobile availability cannot be used as evidence for either description. Nor can the presence of a mobile-payment option establish that a casino is suitable for someone who has enrolled in a self-exclusion scheme.
The regulatory check is separate again. Remote gambling offered to consumers in Great Britain must be provided by an operator holding the relevant UK Gambling Commission licence, regardless of where the operator or its key equipment is located. The Commission is the regulator for commercial gambling in Great Britain, and its public register is the appropriate place to check an operator’s licence before any deposit. A payment logo is not a substitute for that check; logos are not regulators, however confidently they sit in a cashier.
UK-licensed casinos must provide responsible-gambling tools, including self-exclusion, and must offer an internal complaints process with access to an approved Alternative Dispute Resolution service. Those duties do not turn Siru Mobile into an indicator of GamStop connection. The two questions remain independent:
- whether the casino accepts Siru Mobile;
- whether the operator has the relevant UK licence and its stated self-exclusion arrangements.
A search for non-GamStop casinos that accept Siru Mobile therefore cannot be answered by matching the payment method to an assumed status. The available payment route says nothing conclusive about GamStop participation. Any claim that a named casino is connected to, or not connected to, GamStop requires operator-specific evidence that is separate from the casino cashier. Without that distinction, a deposit option can be mistaken for a self-exclusion test, which is a poor piece of financial and regulatory analysis.
Welcome Offers and Pay-by-Phone Deposits
A Pay by Phone deposit does not automatically qualify for a welcome offer. Eligibility is set by the operator’s terms and can depend on the payment method selected at the cashier. A specialist review identifies MrQ, Duelz, Mr Vegas and Videoslots as accepting pay-by-phone deposits for bonus eligibility. That does not make the arrangement universal across Siru Mobile casinos, and the named operators’ terms remain the controlling document when an offer is claimed.
The arithmetic of a common UK welcome structure is straightforward. A 100% match up to £100 means that a qualifying £100 deposit can generate £100 in bonus funds, subject to the stated cap. The balance created by the deposit and match is not automatically withdrawable. A 35x wagering condition applies before bonus-related funds or winnings can be released, with the precise calculation depending on the operator’s rules for the qualifying balance.

The payment method can therefore change the value of an advertised offer. If a casino excludes Pay by Phone deposits, the same promotion may appear on the site but not apply to a Siru Mobile-funded account. A specialist review has found no general Boku deposit restriction on the evaluated platforms, but that observation should not be transferred to Siru Mobile or treated as a permanent rule. The cashier and bonus conditions need to agree before the deposit is made.
Expiry is another financial condition rather than small print. The example terms give bonus funds a 30-day life and bonus spins a 72-hour life. The periods run separately: unused bonus funds can expire after the funds’ deadline, while spins can disappear earlier under their own deadline. A promotion described as a slots bonus is therefore not necessarily a no-deposit bonus, and “no deposit” cannot be assumed merely because the offer mentions spins.
The practical calculation is simple: first establish whether Siru Mobile is an eligible funding method, then identify the match cap, wagering multiplier and expiry clock. If the payment method fails the eligibility condition, the advertised bonus value is zero, regardless of the headline offer.
What are the deposit limits at pay by mobile casinos?
Boku deposits are usually limited to £30 per transaction, although some casinos or mobile networks may allow £40 or £50. Network limits are typically about £10 per transaction and £30 per day, and PAYG deposits cannot exceed your remaining phone credit.
Are Boku casinos still available in the UK in 2026?
Yes, a small number of UK casinos still accept Boku, including BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino. Jackpot Mobile Casino and Peachy Games are also identified as direct-Boku sites.
Why are UK casinos dropping Boku?
Operators have been dropping Boku because of compliance risk, not because the UK Gambling Commission introduced a ban on Boku by name. Some have switched to Fonix or Siru Mobile, while others have removed pay-by-phone deposits.
How does Boku work?
Choose Boku in the casino cashier, enter an eligible deposit amount and your phone number, then confirm using the SMS verification code. The charge is added to your monthly phone bill or deducted from your PAYG credit; Boku can be used for deposits, not withdrawals.
How can I be sure Boku is available where I live?
Boku and Fonix are supported by EE, O2, Vodafone and Three. Check whether Boku appears in the casino’s cashier, since the operator’s available payment options may differ.
