Phone-payment options vary by casino, and deposits may have separate limits, withdrawal routes and bonus conditions.
Where Siru Mobile Still Appears in UK Casino Cashiers
Siru Mobile has not disappeared from UK casino cashiers, but the available operator list is small. Specialist casino reviews identify Mr Vegas and Videoslots as sites offering Siru Mobile. Treat those names as a starting point rather than a guarantee that the option will appear for every account: payment menus can change, and an operator may show different methods depending on the customer or the time of checking.
The practical check is the cashier on the casino account you intend to use. Look for Siru Mobile by name among the deposit methods before choosing a site on the assumption that it supports it. A general statement that a casino takes Pay by Phone does not necessarily mean it accepts Siru Mobile specifically. Nor does finding Siru Mobile listed in an older review prove it is still available.
This distinction matters because pay-by-phone options have shifted. A specialist review of the market’s changes reports that, since 2023, some operators that moved away from Boku introduced Fonix or Siru Mobile instead, while others removed phone payments altogether. That describes different operator choices, not a single replacement service adopted across UK casinos. The relevant question is therefore not simply whether a casino accepts payment by phone, but which named service its cashier currently offers.
For comparison, the same review identifies MrQ and Duelz as accepting Fonix. They are useful examples of the distinction, not confirmed Siru Mobile casinos. If your preferred method is Siru Mobile, seeing Fonix in a cashier does not make it an equivalent option for your intended deposit. The provider names are not interchangeable labels for one shared payment route.
Boku is another separate method. Some casinos have been reported as accepting Boku, but that does not make them Siru Mobile sites. The Boku list includes operators such as BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino. Those names should not be read as evidence that each also supports Siru Mobile. A payment method has to be confirmed at the individual cashier; a casino’s support for one phone-payment provider does not establish support for another.

That is why a broad search for mobile casinos can produce misleading results. A page may group several services under the general idea of paying by phone, even though the operator accepts only one of them. If the cashier names Boku or Fonix but not Siru Mobile, it is not a confirmed Siru Mobile option. Likewise, an old reference to a provider should not outweigh what the current cashier actually displays.
A short, identifiable set is not the same as a complete list, particularly when payment options can change.
If you are checking a casino from a phone, the same principle applies: use the cashier rather than assuming that a mobile-friendly site supports a particular payment method. A casino being accessible on Android does not tell you whether Siru Mobile is offered. The payment-provider name needs to appear as an available deposit choice.
Before depositing, verify that the operator holds a current UK Gambling Commission licence and check the licence number on the Commission’s public register. Then confirm Siru Mobile in the account cashier. These checks answer different questions: the register concerns the operator’s licensing, while the cashier shows whether the specific payment option is available to you.
Siru Mobile, Boku and Other Ways to Pay by Phone
Siru Mobile and Boku are separate payment services, not two names for the same option. A casino cashier may offer one, both or neither, and the fact that a casino accepts Pay by Phone does not mean it accepts every phone-payment provider. Check the payment methods shown in your own account before deciding how to fund it.
That distinction matters when you are looking for an alternative to Siru Mobile. Boku is one possibility, but it is not a substitute that automatically works wherever Siru Mobile does. Fonix is another service used for Pay by Phone deposits. The payment route and the operator’s cashier determine which of these you can use; your mobile network’s support for a service alone does not guarantee that a particular casino offers it.
Siru Mobile
Check the cashier to see if this specific service is offered.
Boku
A separate phone-payment method used by various operators.
Fonix
Another distinct service for Pay by Phone deposits.
Compare the route, not just the label
Pay by Phone is the broad description for paying through a mobile service, rather than a card or bank transfer. Under that umbrella, services have their own names and arrangements. Boku, Siru Mobile and Fonix should therefore be checked as distinct options, not treated as interchangeable brands.
Pay by Phone and Fonix are supported by EE, O2, Vodafone and Three. That tells you which networks support those services, but it does not establish that every casino accepts them or that every account on a supported network can use them. The casino must offer the relevant method, and the mobile provider must allow the payment. A missing option in the cashier cannot be solved by selecting a different network name.
The practical comparison is often between a direct phone-payment option and a route through another payment service. If Siru Mobile is absent, look for the names actually displayed in the cashier. Fonix may be available at an operator that does not offer Siru Mobile. Boku may appear at a different operator. Neither should be described as a universal replacement: availability depends on the individual casino.
This is also why a list of casinos accepting one service can become misleading when applied to another. A casino’s payment page may change, and a method that was once visible may later disappear. Treat the current cashier as the relevant check for your own account, rather than assuming that an old reference to a provider applies across the operator’s sites or brands.

Funding Neteller through Boku
There is also an indirect route: a specialist review describes funding a Neteller account with Boku, then using Neteller to deposit at a casino that accepts that e-wallet. This is different from making a Boku deposit directly to the casino. In the first case, Boku is used to add money to Neteller; the casino deposit is then made through Neteller.
That route depends on each step being available to you. You need access to the Boku option for funding Neteller, and the casino needs to accept Neteller. A casino that accepts Neteller does not thereby accept Boku directly, just as a direct Boku cashier does not establish that Neteller is supported. Check both services before relying on the route.
An e-wallet also adds a separate account between the phone payment and the casino. That can make the route less straightforward than using a direct cashier option, and it is sensible to confirm the applicable terms with both services before transferring money. Do not assume that a payment method displayed by one provider will be available for every transaction involving another.
What to check before choosing
Start with the casino cashier and identify the exact provider listed. Then check whether your mobile network supports that service and whether it is available for your account. If the casino offers Fonix but not Siru Mobile, that is a different payment route, even though both relate to paying by phone. If it offers Boku, do not assume the Boku option is equivalent to Siru Mobile.
DO
- Verify the operator holds a current UKGC licence.
- Check the casino cashier for the specific provider name.
DON’T
- Assume Pay by Phone means Siru Mobile is available.
- Treat Boku or Fonix as equivalent to Siru Mobile.
For Neteller, confirm that the casino accepts the e-wallet and that Boku can be used to fund it before treating the indirect route as an alternative. The sequence is only useful when both parts work. Comparing payment methods by their names and the steps they require is more reliable than searching for a generic “mobile deposit” label and assuming it covers them all.
A phone-based payment can be convenient if it is already supported by your network and the casino, but its label alone tells you little about where it can be used. Check the cashier, confirm the provider, and choose the route that is explicitly available rather than treating Siru Mobile, Boku and Fonix as versions of one service.
Using Pay by Mobile for Online Slots
Pay by Phone is a way to fund a casino account, not a type of slot or a feature that unlocks particular games. If a casino accepts Siru Mobile, that tells you something about its cashier; it does not tell you which slots are available, whether they work on your device or whether the casino has a separate slots app. Those details depend on the operator and its game offering.
The same distinction applies when you see a casino described as a Siru Mobile slots site. The payment method and the games are separate parts of the service. Check the casino’s games section to see what it offers, and its cashier to see whether Siru Mobile is currently available. A payment option listed on an old review or remembered from a previous visit is not proof that it remains in the cashier.

Paying by phone also does not determine whether you are playing for real money. A deposit adds funds to your casino account; the games you choose and the account balance determine how you play. If you are looking for free slot play, check the casino’s own terms and games pages rather than assuming that a phone-payment option includes a free-play mode. “Siru Mobile slots” is not a separate category of game.
Mobile play and slot rules
A phone screen does not change the rules for online slots in Britain. Online slot autoplay is banned, so you cannot set a game to play repeated spins automatically. Each spin must last at least two and a half seconds. These requirements apply to the game, whether you access it through a mobile browser or an app.
There is also a maximum stake for each online slot game cycle. For customers aged 25 and over, the limit is £5. For customers aged 18 to 24, it is £2. The £5 limit for all adults aged 25 and over took effect on 9 April 2025. These are stake limits, not deposit limits: the amount you put into an account through a payment method is a different matter.
Online slot autoplay is banned in Britain, and each spin must last at least two and a half seconds.
The operator must verify your age before allowing you to deposit into a gambling account. Online gambling is legal in Great Britain for people aged 18 and over when the operator holds the required UK Gambling Commission licence. Before depositing, check that the casino has a valid licence and verify its licence number on the Commission’s public register. A familiar payment logo or a polished mobile site is not a substitute for that check.
Choosing a slots experience
If you want to play on a phone, check whether the casino’s games work in your browser or whether the operator provides an app. Do not assume that an app is required, or that every game in the desktop catalogue will behave identically on a smaller screen. The casino’s own game information is the place to confirm what is available on your device.
You can also inspect the game’s rules and displayed stake controls before you play. The payment method does not change a slot’s permitted stake, spin speed or autoplay rules. Nor does the phrase “mobile slots” mean that the games are designed only for phones. It describes how you access them, not a distinct set of games.
For a legitimate real-money casino, the relevant check is the operator’s licence, not whether it accepts Siru Mobile. A casino can offer a phone-payment option without that option proving anything about the games or the operator’s standing. Check the licence before funding an account, then review the casino’s game information and the controls shown in the slot itself.

Deposit Limits and Phone-Bill Restrictions
A Boku deposit is constrained by more than the amount shown in a casino cashier. The mobile network may apply its own daily ceiling, while the casino can set a separate transaction limit. Your available phone credit or bill arrangements can also affect whether a payment is accepted. These limits are worth checking before you try to deposit, because a cashier’s displayed maximum may not tell the whole story.
The available accounts of Boku limits do not agree on a standard per-transaction cap. One specialist casino review describes a UK limit of £30 per transaction, with some casinos or networks allowing £40 or £50. Other descriptions put the emphasis on a £30 daily network limit and do not specify a per-transaction cap. A separate specialist review gives a lower figure of about £10 per transaction alongside the £30 daily limit. Those figures should not be combined into a single rule: they represent differing accounts, and the applicable limit can depend on the casino and mobile operator.
The practical point is to treat the amount offered by the cashier as only one part of the picture. Even if the casino permits a deposit, your network may reject it once its own daily limit has been reached. Specialist payment information attributes that daily limit to the mobile operator rather than the casino. If a payment fails, the restriction may therefore sit with the network, not with the gambling account.
Boku transaction limits
The available limits for Boku vary. Some reports suggest a £30 per transaction limit, while others mention £40 or £50. There are also reports of a £30 daily network limit.
The same specialist information describes a £30 daily network limit, but accounts differ over whether a separate per-payment ceiling applies. Check the current terms shown by the casino and, if necessary, your network’s rules rather than relying on a figure quoted elsewhere. Limits can change, and a number reported for one operator or network should not be treated as a promise that another will accept the same amount.
Pay as you go customers face an additional restriction: a Boku payment can draw only on the credit remaining on the phone. A specialist payment review describes a payment being declined when the available prepaid balance is insufficient. So even where the casino and network limits would allow a deposit, the balance on your account can still be the binding constraint. For customers whose mobile payments are charged to a monthly bill, the relevant restriction may instead be the operator’s rules for billing transactions.
Before depositing, check both the casino’s displayed limit and the mobile operator’s applicable terms. For a prepaid account, confirm the remaining credit as well. This helps distinguish a casino limit from a network cap or a lack of phone balance—three different reasons a payment might not go through.
Real-Money Play and What a Phone Deposit Does Not Cover
A Pay by Phone deposit can put money into a casino account for real-money play, but it does not make the payment method a route for taking money back out. Boku is deposit-only: you can use it to fund an account, but casino funds and winnings cannot be returned to you through Boku. That distinction matters when you are comparing ways to pay. A deposit method describes how money enters the account, not how every later transaction is handled.
Casinos That Accept Maestro in the UK: Payment Guide
This also means a phone deposit is not the same as free play. If you deposit money and use it to play slots or other casino games, you are gambling with real funds. Any winnings are recorded in your casino account, but Boku cannot transfer them back to your phone bill or prepaid balance. Before depositing, make sure you understand the casino’s available payment arrangements for the full cycle of play, rather than choosing a method based only on how you can pay in.
The same principle applies when a search or offer mentions Siru Mobile. A casino’s acceptance of a particular phone payment does not, by itself, tell you whether a deposit can be withdrawn through that service. Check the cashier and the operator’s payment terms for the exact method you intend to use. Do not assume that a phone deposit makes the casino account function like a phone wallet.
For real-money gambling in Great Britain, the operator must hold the relevant UK Gambling Commission licence. Check the operator’s licence on the Commission’s public register before depositing; a payment logo is not evidence of licensing. Operators must also verify your age before allowing you to deposit into a gambling account. Online gambling is for adults aged 18 and over at a licensed site.
Keep the practical distinction clear: Boku can fund casino play, but it cannot carry casino funds back to you. This is not a minor technical detail to discover after a win. Treat depositing and withdrawing as separate parts of using an account, and confirm that the operator’s arrangements suit you before you commit money.
Attention Boku is a deposit-only method; you cannot use it to withdraw your casino winnings.
Withdrawals Need a Separate Payment Method
A Pay by Phone deposit does not give you a route for receiving casino winnings. Boku is for deposits only: funds cannot be withdrawn back to it. If you plan to use Boku to fund an account, arrange a separate withdrawal method as part of setting up that account, rather than assuming the payment used to deposit will work in reverse.
A debit card, an e-wallet or a bank transfer may be suitable alternatives, depending on the options the casino makes available. Before depositing, check the cashier’s withdrawal section and register an available method. The option you intend to use should be one you can access and whose details you can provide accurately. A payment route appearing in the deposit menu does not establish that it is available for withdrawals.
It is also worth distinguishing debit cards from credit cards. UK-licensed casinos cannot accept credit-card payments for gambling, and that restriction includes credit-card funding routed through a money service business. Do not treat a credit card as a fallback for funding gambling or expect it to solve a withdrawal problem. Check the casino’s own instructions for the permitted withdrawal routes.
Casinos that accept Monzo in the UK: payment guide
The same planning point applies if you are looking at Siru Mobile: a phone-based deposit option should not be taken as evidence that winnings can be sent to your phone account. Confirm the available withdrawal methods directly with the operator before choosing a casino or making a deposit. This matters whether you are searching for Siru Mobile casinos with debit-card withdrawals, instant banking, or a direct withdrawal to the original phone-payment method: those are separate questions, and the name of a deposit method does not answer them.
If no suitable withdrawal option is available to you, pause before depositing. A later request to withdraw may require you to use a method you have not set up, or one you cannot use. Checking first lets you decide whether the account fits your payment needs without relying on an assumption that Boku—or any other Pay by Phone service—can receive casino funds.
Alternatives When Siru Mobile Is Unavailable
If Siru Mobile is not shown in a casino’s cashier, the practical alternatives are another Pay by Phone option or a different way to fund your account. Payment menus vary by operator, so check the cashier while logged in rather than assuming that a method available elsewhere will be offered to you.
Fonix is one possible phone-payment alternative. Pay by Phone and Fonix are supported by EE, O2, Vodafone and Three, although that does not mean every casino accepts both services. A specialist casino review identifies MrQ and Duelz as operators accepting Fonix. Treat that as a lead to check, not a guarantee that the method remains available: confirm the current options directly with the casino before depositing.
Alternatives to Siru Mobile
- Check the cashier for Fonix availability
- Consider using Boku to fund a Neteller account
- Look for other non-phone payment methods
- Confirm the operator holds a valid UKGC licence
Another route described in a specialist review is to use Boku to add funds to a Neteller account, then deposit from Neteller at a casino that accepts it. This involves two separate steps, and the casino must support Neteller for the second one. Check the payment terms for both services, including any conditions on funding or account use, before relying on this route.
You can also choose a non-phone payment method offered by the casino. The right alternative depends on the methods in its cashier and on whether you are comfortable using an e-wallet or another account-based service. Do not assume that an operator which accepts phone payments will offer the same options as another one.
Before depositing, verify that the casino holds a current UK Gambling Commission operating licence. You can check its licence details on the Commission’s public register. This matters independently of the payment method: seeing Siru Mobile, Fonix or another option in a cashier does not establish that the operator is licensed for the British market.
In short, when Siru Mobile is unavailable, check for Fonix first, then consider whether Neteller or another listed method suits you. Confirm availability and the operator’s licence at the point you plan to deposit, since payment options can change.
How a Boku Deposit Is Confirmed
A Boku payment starts in the casino cashier. Choose Boku from the payment options, enter the deposit amount and provide a mobile number. The transaction then requires confirmation using a verification code sent by SMS. Enter that code where prompted to approve the payment.
Casinos That Accept AstroPay in the UK: How to Check
Take care to distinguish this process from paying with Siru Mobile. The services are separate, so Boku’s confirmation steps do not establish how a Siru Mobile payment works or whether a particular cashier offers it. Follow the instructions shown for the method you have selected.
The amount may also affect whether the cashier accepts the deposit. A specialist review reports that Boku payments are restricted to sums divisible by ten: its examples include £10, £20 and £30. That is a reported payment condition, not a reason to assume every cashier currently applies it in the same way. Check the amount options displayed before confirming, rather than relying on an amount accepted at another casino.
If the payment does not proceed, first check that you selected Boku, entered the amount shown as available and supplied the intended mobile number. Then check that you have received the SMS and entered its code correctly. A missing or rejected code means the confirmation has not been completed; do not assume the deposit went through simply because you reached the verification screen.
The cashier’s displayed instructions matter more than a general description. If Boku is not listed among the available methods, these steps cannot be used to make a deposit there. If the method is listed but the amount or verification prompt differs, use the information presented by that operator before approving the payment. This is a practical distinction when looking for a small Siru Mobile deposit: a Boku amount rule should not be treated as a Siru Mobile minimum or as evidence that the two services share a cashier process.
Boku Confirmation Process
Step 1: Selection
Choose Boku from the casino cashier options, enter the amount, and provide your mobile number.
Step 2: Verification
Wait for a verification code to be sent to your phone via SMS.
Step 3: Approval
Enter the received code into the prompt to complete the payment.
A Phone Payment Does Not Tell You a Casino’s GamStop Status
A casino offering Siru Mobile or another Pay by Phone option does not, on that basis, reveal whether it is connected to GamStop. Payment methods and self-exclusion arrangements are separate matters. A cashier listing a phone payment is not evidence of a casino’s GamStop status, and the absence of that payment option tells you nothing about it either.
If you are checking whether a casino is connected to GamStop, look for information from the operator and verify its regulatory status independently. Do not treat a payment-method page, a search result or an advert as proof. If you have self-excluded through GamStop, looking for a site outside the scheme is not a substitute for the protection you chose.
For a UK-facing online casino, check that the business holds a current UK Gambling Commission operating licence before depositing. The Commission regulates gambling, including remote gambling offered to consumers in Great Britain. Its remit applies to those services regardless of where the operator’s key equipment is located. The Commission is the sole regulator for commercial gambling in Great Britain and issues operating licences to businesses; it also issues personal licences to individuals working in relevant roles.
Search the Commission’s public register for the operator and confirm that the licence is current and covers the gambling activity being offered. A familiar brand name alone is not enough: the register lets you check the licensed business behind the site. A payment provider’s presence in a cashier is not a replacement for this check.
The distinction matters when comparing casinos that accept Siru Mobile with casinos that are not connected to GamStop. Those descriptions refer to different things, and one cannot establish the other. A UKGC licence check can establish whether the operator is licensed for the relevant market; it does not, by itself, tell you whether the casino participates in GamStop. Verify each point separately before deciding whether to open or fund an account.

Welcome Bonuses and Pay-by-Phone Deposits
A casino may accept Siru Mobile for deposits without counting that payment towards its welcome offer. Bonus eligibility is set by each operator, so the cashier showing a Pay by Phone option does not tell you whether a deposit will qualify. Check the offer’s terms before paying in.
A specialist review reports that MrQ, Duelz, Mr Vegas and Videoslots have accepted pay-by-phone deposits for bonus eligibility. Treat that as a point to verify rather than a standing promise: payment options and promotion rules can change, and the terms attached to the offer you see are what matter. This is relevant whether you are looking for a Siru Mobile casino welcome bonus or plan to use another phone-payment method.
Read the conditions for the specific promotion, including which deposit methods count, any qualifying deposit requirement, wagering rules and expiry dates. Pay attention to whether the wording covers all deposits or names particular methods. If it is unclear whether Siru Mobile qualifies, ask the operator before depositing and keep its response. Otherwise, you could make a deposit expecting a bonus that is not applied.
A specialist review describes a common welcome-offer format as a deposit match, but the headline alone is not enough to judge its value. The conditions determine how bonus funds can be used and when they expire; they are not uniform across casinos. Do not assume that a bonus advertised for slots, or a no-deposit promotion, is available simply because the casino accepts Siru Mobile. The payment method and the promotion are separate parts of the offer.
If bonus eligibility matters to you, confirm both the current payment option and the promotion terms before making a real-money deposit. A casino’s general statement that it offers bonuses does not establish that a particular Siru Mobile deposit qualifies.
What are the deposit limits at pay by mobile casinos?
For Boku, the standard UK limit is £30 per transaction, although some casinos or mobile networks may allow up to £40 or £50. Network-level limits are often 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, but the list has been shrinking since 2023. Check the casino cashier, as payment options can change.
Are Boku deposits eligible for casino bonuses?
Boku deposits generally do not come with specific bonuses, and bonus eligibility varies by casino. Check the bonus terms before depositing.
Are there any Boku casinos left in the UK?
Yes. BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino are among the operators reported to accept Boku; Jackpot Mobile Casino and Peachy Games are also identified as direct-Boku sites. Confirm availability in the casino cashier before depositing.
