Casinos That Accept Siru Mobile in the UK
Available in GB
Siru Mobile availability can vary by casino, while deposits, withdrawals, limits and bonus terms affect how pay-by-phone works.
Is Siru Mobile still accepted at UK casinos?
Yes. Siru Mobile remains an option at some UK casinos, but it is not a payment method you can assume will be available everywhere. A specialist review identifies Mr Vegas and Videoslots as accepting Siru Mobile deposits. That is a useful starting point, not a guarantee that the method will still appear in every account’s cashier: payment options can change, and availability may depend on the operator’s current arrangements.
The distinction between Siru Mobile and Boku matters. Both are Pay by Phone methods, but acceptance of one does not mean a casino accepts the other. A site that takes Boku is not automatically a Siru Mobile casino, and the reverse is also true. If you are looking specifically for Siru Mobile, check the casino’s payment information or cashier rather than relying on a general label such as “mobile payments”.
The available operator information is specific: Mr Vegas and Videoslots are named as Siru Mobile options, while MrQ and Duelz are identified with Fonix, a separate Pay by Phone service. These examples show why broad lists of “mobile casinos” can mislead. They may group together different services, or include operators that have changed their payment options since a list was prepared. A casino’s use of one provider is not evidence that it supports another.
There is also a wider shift away from Boku. A specialist review describes operators as having moved away from Boku since 2023, with some switching to Fonix or Siru Mobile and others removing Pay by Phone altogether. Separately, information on the remaining Boku casinos describes their number as small and the list as shrinking. Those statements concern Boku, not Siru Mobile: they should not be read as proof that Siru Mobile is disappearing at the same pace, or that every former Boku casino has replaced it with Siru Mobile.

Nor was Boku prohibited by a UK Gambling Commission rule naming the payment service. The Commission did not introduce a specific Boku ban. Individual casino operators made their own decisions to drop it because of compliance risk. That helps explain why payment availability has changed from operator to operator, rather than through a single regulator-led switch affecting every casino at once.
When considering whether Siru Mobile is still available in the UK, separate three questions: whether the operator serves British customers, whether it holds the relevant UK Gambling Commission licence, and whether Siru Mobile is currently offered as a deposit option. One answer does not establish the others. The Commission regulates remote gambling offered to consumers in Great Britain, wherever the operator’s key equipment is located. Online casinos serving the British market must hold the appropriate licence; a payment logo or a claim that a site accepts UK customers is not a substitute for checking its licence.
Before registering or depositing, look for Siru Mobile in the operator’s own payment information and confirm it is available to you. Then check the casino’s licence on the UK Gambling Commission’s public register. This is particularly worthwhile if you have found an old list: payment pages can become outdated, and a third-party mention may not reflect the current cashier. The question is not simply whether Siru Mobile casinos are still available, but whether the particular licensed casino you intend to use currently supports Siru Mobile.
Searches for Android casinos do not change the basic distinction. A casino may have a mobile-friendly site or app without offering Siru Mobile, just as a Siru Mobile listing does not establish compatibility with every device or account. Check the payment method itself rather than inferring it from the word “mobile”.
Do
- Check the casino’s payment information for Siru Mobile
- Verify the operator’s UK Gambling Commission licence
- Treat named operators as leads to verify
Don’t
- Rely on general labels like “mobile payments”
- Assume Boku acceptance means Siru Mobile is available
- Trust old lists without checking the current cashier
So, Siru Mobile is still reported at named UK-facing operators, but acceptance is selective. Treat Mr Vegas and Videoslots as leads to verify, not as an exhaustive or permanent list of every casino that accepts Siru Mobile. Keep Siru Mobile separate from Boku and Fonix when comparing payment options, and verify both the current cashier and the operator’s UKGC licence before depositing.
How pay-by-mobile deposits work—and what happens at checkout
A Pay by Phone deposit is completed through the casino’s cashier, but the payment is billed through your mobile account rather than paid by card. With Boku, the amount is either added to your monthly phone bill or taken from your pay-as-you-go (PAYG) credit. That means the phone number you enter must be one you can access during checkout: the confirmation step is sent to it by text.
The process is straightforward, although the exact wording on the cashier screen can vary:
- Open the casino cashier and choose Boku as the deposit method.
- Enter the amount you want to deposit and your mobile number.
- Read the payment details shown, then request the SMS verification code.
- Enter that code to confirm the transaction.
The text-message code is part of the payment authorisation, not a casino password. Check that the number is correct before requesting it, and use a phone on which you can receive the message. If the code does not arrive, do not keep submitting the payment: check the number and the on-screen instructions first.
After confirmation, the deposit is charged through the mobile account associated with that number. Monthly-bill customers will see the charge on their phone bill; PAYG customers have the amount deducted from their available credit. So the same checkout flow can lead to a different billing route depending on your mobile plan.
This is also why the payment is not equivalent to entering a debit-card number. You are authorising a charge through your mobile provider, and the transaction depends on the phone number and its billing arrangement. Keep the confirmation screen until the casino account reflects the deposit. If the cashier reports a problem, check the payment status before trying again, so you do not accidentally submit a second request.
Casinos that accept Litecoin in the UK: what to check
Siru Mobile and Boku are separate payment names, so Boku’s steps should not be treated as proof that a casino’s Siru Mobile option works in the same way. Follow the instructions displayed for the method actually offered at checkout. If you are looking for a Siru Mobile deposit, the important first check is the provider name shown in the cashier; a general Pay by Phone label alone does not identify which service will process it.
Boku’s role in this process is to route the deposit through your mobile account. The casino cashier starts the request, your phone receives the confirmation message, and your mobile billing arrangement determines whether the amount is added to a bill or deducted from prepaid credit. No bank-card details are entered as part of the described Boku checkout.
Using a mobile payment for online slots
A Pay by Phone deposit can fund a casino account that you then use to play online slots, provided the casino accepts that payment method. The payment choice does not determine which games are available: it is the operator’s games catalogue and account terms that do that. Nor does a casino accepting Siru Mobile mean that every slot on its site has been checked as compatible with a particular payment method. Deposits and games are separate parts of the service.
Casino Payments: Cards, E-Wallets and Crypto
A specialist review identified Mr Vegas and Videoslots as accepting Siru Mobile deposits, while MrQ and Duelz were listed for Fonix. Treat those names as a snapshot rather than a lasting promise: operators can change their cashier options. Before adding money, check whether the payment method is displayed in the casino cashier and whether the operator holds a current UK Gambling Commission operating licence. A licence is required for a casino legally serving players in Great Britain; the Commission regulates remote gambling offered to consumers there, even if the operator’s key equipment is elsewhere.
If you are looking for a Siru Mobile slots app, distinguish the payment service from the casino’s app or mobile website. Siru Mobile is a way to pay, not a slots app or a games provider. The relevant question is whether the casino makes the payment option available to your account, and separately whether its slots can be played on your device. A payment listing alone does not establish that a particular game is available in an app, or that it is available in free-play mode.
British online slots also have rules that apply regardless of how you funded the account. Autoplay is banned, so you cannot set a slot to play a run of spins automatically. Each spin must last at least 2.5 seconds. These rules are intended to slow the pace of play; a mobile payment does not create an exception. The maximum stake for an online slot game cycle is £5 for customers aged 25 and over, and £2 for those aged 18 to 24.

Age checks are another part of the process. Operators must verify a customer’s age before allowing a deposit, and online gambling in the UK is for people aged 18 and over at sites holding a UK Gambling Commission licence. Seeing Siru Mobile in a cashier is not a substitute for checking the operator’s licence. You can verify a licence number on the Commission’s public register before depositing.
The phrase “Siru Mobile slots” can therefore mean two different things: slots at a casino that accepts Siru Mobile, or a particular game supposedly linked to Siru. The payment method can answer the first question only when the casino currently offers it. It does not identify a special set of Siru games or show that a named slot supports Siru directly. Once a deposit is in your casino account, the games you can access depend on the operator’s catalogue and applicable account conditions.
For a straightforward check, confirm the casino’s UKGC licence, look for Siru Mobile in its payment options, and then review the slot’s own rules before playing. That keeps the payment decision separate from the game decision—and avoids mistaking a payment logo for evidence about a casino’s entire service.
Licensing
Online casinos serving the British market must hold the appropriate UK Gambling Commission licence; a payment logo is not a substitute for checking the public register.
Real-money play, withdrawals and the missing second payment method
A Pay by Phone deposit can put money into a casino account for real-money play, but it does not provide a route for taking winnings back out. Boku is deposit-only: the casino cannot send a withdrawal to your phone bill or return it to your mobile balance. Treat the deposit and withdrawal sides as separate parts of the payment arrangement.
Before depositing, register another method that the casino accepts for withdrawals, such as a debit card, e-wallet or bank transfer. Check that the method is available on your account and that you can use it; seeing Pay by Phone in the cashier does not mean the same option can handle a payout. If you do not arrange an alternative, winnings may remain in your casino balance until you meet the operator’s withdrawal requirements using another method.
This distinction matters when comparing sites described as accepting Siru Mobile or another mobile payment. A payment label at deposit tells you how money may enter the account; it does not establish how withdrawals work. Nor should acceptance of one Pay by Phone provider be taken as evidence that a different provider is supported. Confirm the payment options shown by the casino and read its withdrawal terms before committing funds.
Giropay at UK Casinos: Check Current Availability
For real-money slots, the payment method is only one part of the decision. A casino serving players in Great Britain must hold the relevant UK Gambling Commission operating licence. Check the licence number on the Commission’s public register before depositing. Licensed operators must also provide account controls, including ways to set limits, and an internal complaints process with access to an approved Alternative Dispute Resolution service. These protections do not change the basic payment limitation: Boku cannot pay winnings out.
Do not assume that a casino will let you withdraw to any card or account simply because it accepts that method for deposits. Look for the withdrawal options and any conditions in the operator’s terms, then register an eligible alternative before playing. If the casino does not offer a method you can use, a successful mobile deposit will not solve the problem of accessing a later payout.
The practical rule is simple: consider Pay by Phone a way to fund play, not a complete cash-in and cash-out service. Plan the withdrawal route first, and only then decide whether the deposit option suits you.
Mobile deposit limits, phone balance and billing
The figures published for Boku do not form one consistent set of limits. One specialist casino-payment review describes a standard ceiling of £30 per transaction in the UK, while noting that some casinos or mobile networks may permit £40 or £50. Other payment guidance gives a different picture: it reports a network-level limit of £10 per transaction and £30 per day, whereas another account specifies a £30 daily limit but no separate transaction cap. Those descriptions conflict, so none should be treated as a guaranteed limit for your account.
A casino cashier may allow a deposit amount that your mobile network will still reject if you have reached its own specific limit.
A specialist review also attributes daily Boku caps to the mobile operator rather than the casino. That distinction matters: a casino cashier may allow a deposit amount that your network will still reject if you have reached its limit. The limit applied can therefore depend on both the casino’s payment settings and the rules of the network linked to your phone. Check the amount shown in the cashier and your network’s current payment restrictions before relying on a particular figure.
The way Boku is billed depends on your mobile plan. With a monthly contract, the deposit is added to your phone bill. With a pay-as-you-go plan, it is taken from your available credit. A prepaid transaction cannot exceed the balance left on the phone; if there is not enough credit, the payment is declined. This balance restriction can be lower than any casino or network limit.
These are Boku conditions, not a reliable guide to Siru Mobile limits. Pay by Phone services can have different arrangements, and a Boku figure should not be carried across to another payment provider. If the casino offers a mobile payment option, check the provider named in the cashier and the terms attached to that option.
A mobile bill is not an unlimited spending route: the network’s cap, the casino’s own settings and, for prepaid users, the remaining balance can each constrain a deposit. Because published Boku descriptions disagree on whether there is a separate per-transaction ceiling, confirm the current restriction with the casino or mobile operator rather than planning around a figure from a general review.

What £5, £10 and other minimum-deposit searches can—and cannot—tell you
A £5 minimum-deposit claim needs to name the payment method and the casino. A rule reported for Boku does not establish what Siru Mobile accepts, and a casino’s minimum deposit is not automatically the same as a payment service’s permitted transaction amount.
For Boku, a specialist review describes deposits as restricted to amounts divisible by ten, such as £10, £20 or £30. On that account, £5 would not be a valid Boku deposit amount. That does not prove that every casino accepting Boku sets its minimum at £10: the casino’s own cashier and payment terms determine the minimum it will accept.
The same review gives £30 as the standard UK Boku transaction limit, while noting that some casinos or mobile network operators may allow £40 or £50. Those figures describe reported limits, not a guaranteed allowance at every operator. Nor should a maximum transaction limit be mistaken for a minimum deposit. They answer different questions.
For Siru Mobile, these Boku figures cannot settle whether a £5 deposit is possible or what minimum a particular casino applies. You need to check the operator’s current payment information and the amount options shown for Siru Mobile. If Siru Mobile is not listed in the cashier, a Boku rule does not make it available.
The word “instant” also needs care. A description of a payment as an instant deposit does not establish that every transaction will be credited immediately, or that Siru Mobile is offered at that casino. Confirm the named method and the operator’s stated processing details before depositing.
Attention: A payment label tells you how money may be added to an account, but it is not evidence of the site’s regulatory status or licensing for Great Britain.
Likewise, a casino accepting a mobile payment does not, by itself, establish that it is licensed for Great Britain or that it is outside GamStop. Check the operator’s UK Gambling Commission licence on the Commission’s public register before depositing. A payment label tells you how money may be added; it is not evidence of the site’s regulatory status.
Alternatives when Siru Mobile is unavailable
If Siru Mobile is not shown in a casino’s cashier, there are two documented routes to consider: use another Pay by Phone service, such as Fonix, or use Boku to fund an e-wallet and then pay the casino from that wallet. Neither route means that every casino will offer the same payment options. The cashier and the operator’s terms are the practical checks before you commit to a deposit.
A specialist review identifies MrQ and Duelz as casinos accepting Fonix, and Mr Vegas and Videoslots as accepting Siru Mobile. Treat those names as leads rather than a guarantee that the method is available to you now: payment options can change, and a casino may offer different methods to different customers. If you are considering one of them, confirm that the relevant method appears in its cashier and check that the casino holds a current UK Gambling Commission licence. The regulator’s public register is the place to verify the licence.
Casinos That Accept Monzo UK: What Is Verified
Try Fonix where it is offered
Fonix is a separate Pay by Phone service, not another name for Siru Mobile. It may be an option when the casino does not list Siru, provided the casino itself supports Fonix. A specialist review names MrQ and Duelz as examples of operators accepting it; that is useful for narrowing down where to check, but it does not establish that either cashier will show Fonix for every account or at all times.
Pay by Phone and Fonix are supported by EE, O2, Vodafone and Three. Network support alone does not mean a particular casino accepts a service, or that a transaction will be available on every plan. You need both parts to line up: your mobile provider must support the payment route, and the casino must offer it. If either is missing, the method will not solve the problem.
Operators’ payment menus have changed over time. A specialist review describes operators moving away from Boku since 2023, with some switching to Fonix or Siru Mobile and others removing Pay by Phone altogether. That helps explain why an alternative may exist at one casino but not another. It is not a reason to assume that a casino which once accepted mobile payments still does so.
Where a casino lists both Fonix and Siru, compare the terms shown for the method you intend to use. Do not assume that the services have identical conditions simply because both use your phone. The provider names are different, and the available payment choices are set by the casino and its payment arrangements. If the cashier does not give you a clear answer, ask the operator before depositing rather than relying on an old payment-method list.
Supported Networks
Pay by Phone and Fonix are supported by EE, O2, Vodafone and Three.
Use Boku to fund Neteller
A different workaround described in a specialist review is to use Boku to add funds to Neteller, then deposit at an online casino that accepts Neteller. This is not a direct Boku deposit at the casino. It involves an intermediate e-wallet, so you need to confirm that Boku can be used to fund your Neteller account and that your chosen casino accepts Neteller.
The route can be useful if a casino accepts the wallet but does not offer Siru, Fonix or Boku directly. It also adds a separate service and another set of terms to check. Before relying on it, review the available funding options in Neteller, the casino’s accepted payment methods and any conditions attached to the account. A method appearing in one part of the chain does not establish that the whole route will work for your account.
Pay particular attention to whether the casino allows the payment method for deposits and what method it requires for withdrawals. Boku itself cannot be used to withdraw casino funds; using an e-wallet in the middle does not remove the need to understand the casino’s own cash-out rules. Register an alternative withdrawal method before depositing, and check that its details meet the operator’s requirements.

When no mobile option is available
If Siru and Fonix are absent, and the Boku-to-Neteller route is not suitable, there may be no Pay by Phone route at that casino. Some operators have removed mobile payments rather than replacing them. In that situation, use a payment method the casino currently lists and that you can use under its terms, instead of treating a historical mention of mobile deposits as proof of present acceptance.
Before paying, check the casino’s licence on the UK Gambling Commission register. Remote gambling operators serving consumers in Great Britain must hold the relevant licence, regardless of where their equipment is located. A payment option is not evidence of licensing, and a familiar operator name is not a substitute for checking the register.
There is no single “best” Siru alternative for every player. The relevant choice depends on the services shown by the casino, your mobile provider and the payment account you can use. For a direct phone payment, look for Fonix where it is explicitly listed. If you are considering the wallet route, check Boku funding and Neteller acceptance separately. If neither route is confirmed, choose another payment method offered by the licensed casino or do not deposit until the position is clear.
A non-GamStop claim is not proof of a safe or licensed casino
A casino described as “not on GamStop” is making a claim about its relationship with a self-exclusion scheme. That wording does not establish whether the operator holds a UK licence, whether it accepts Siru Mobile, or whether it is safe to use. Treat those as separate questions rather than assuming that one answer settles the others.
Non-GamStop claims
A "non-GamStop" label does not verify a casino’s regulatory status or the reliability of its payment claims.
The UK Gambling Commission regulates commercial gambling in Great Britain, including remote gambling offered to consumers there. Its remit does not depend on where an operator’s key equipment is located. Businesses providing gambling services need the relevant operating licence; individuals carrying out regulated roles may also need personal licences. The Commission is the sole regulator for commercial gambling in Great Britain.
For a casino serving players in Great Britain, check the operator’s licence against the UK Gambling Commission’s public register before depositing. A polished website or a statement about payment methods cannot substitute for that check. Nor does a licence, by itself, confirm a site’s status with GamStop: the licensing information and any claim about self-exclusion are different matters.
This distinction matters when a site is promoted as both outside GamStop and able to take Siru Mobile. Payment availability is not evidence of licensing, and an assertion about GamStop does not verify that the payment option works for you. Do not treat either claim as confirmation of the other.
Casinos That Accept WebMoney in the UK: Payment Guide
The Commission’s licensing rules apply to remote operators serving Great Britain even if the business or equipment is based elsewhere. A site operating outside the UK regulatory system is not made UK-licensed by being accessible to British users. If its licensing position is unclear, do not infer it from marketing language: look up the operator on the public register and confirm that the licence is current and covers the relevant gambling activity.
The practical point is narrow but important: a “non-GamStop” label tells you neither who regulates the casino nor whether its claims about deposits are reliable. Verify the licence independently before sending money, and assess any self-exclusion statement separately.
Welcome offers and pay-by-mobile bonus terms
A casino’s welcome offer may look available until you choose Pay by Phone. Bonus eligibility depends on the operator’s terms, and a deposit accepted by the cashier is not automatically a qualifying deposit. Check the promotion rules before paying: they should say whether mobile payments count, which deposits qualify and whether you need to opt in.
Casinos That Accept Ethereum in the UK
A specialist review reports that MrQ, Duelz, Mr Vegas and Videoslots accept Pay by Phone deposits for bonus eligibility. That is not a guarantee that every offer at those casinos includes every payment method. Terms can differ between promotions and change, so read the offer attached to your account rather than relying on a general payment-method label. The same check matters if you are looking for a Siru Mobile casino welcome bonus: availability of Siru Mobile and eligibility for a particular promotion are separate questions.
As an illustration of the kind of offer described in specialist casino reviews, a deposit match may add an amount equal to your qualifying deposit, subject to a stated cap, and require wagering the bonus a specified number of times before withdrawal. One review’s example was a 100% match capped at £100, with a 35x wagering requirement. Those figures describe an example, not a standard offer. A wagering requirement means you must place bets totalling the stated multiple of the bonus before the associated funds become withdrawable; the terms determine which games and stakes count.
Expiry rules also need attention. A specialist review gives 30 days for bonus funds and 72 hours for bonus spins, but an individual promotion may set different conditions. Check when the clock starts and what happens to unused bonus value when it expires.
Pay-by-phone promotions may be excluded from welcome offers, so do not deposit first and assume the bonus will be added later. If the terms are unclear, ask the operator before making a payment. Also confirm that the casino holds a current UK Gambling Commission licence: a promotional offer does not establish that a site is authorised to serve UK players.
What are the deposit limits at pay-by-mobile casinos?
For Boku, the standard limit is £30 per transaction, though some casinos or 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-licensed casinos still accept Boku, although the list has been shrinking since 2023.
How do you deposit with Boku at online casinos?
Select Boku in the casino cashier, enter your deposit amount and mobile number, then confirm the payment using the SMS code. The charge is added to your monthly phone bill or deducted from your PAYG credit.
What is the standard Boku deposit limit in the UK?
The standard limit is £30 per transaction, although some casinos or mobile networks may allow up to £40 or £50.
What is the best alternative to Boku for casino deposits?
Fonix and Siru Mobile are alternative Pay by Phone services used by some casinos. Check the casino cashier, since support for one service does not mean it accepts the others.
Can you deposit by phone bill without Boku?
Yes. Some casinos accept other Pay by Phone services, including Fonix or Siru Mobile; check the casino’s cashier to see which options it currently offers.
