The guide distinguishes Siru Mobile from other phone-payment services and covers deposits, withdrawals, and casino licensing.
Is Siru Mobile Still Accepted at UK Casinos?
Yes, Siru Mobile is still associated with a small number of UK casino payment pages, but it is not interchangeable with Boku. They are separate Pay by Phone services, and a casino accepting one does not automatically accept the other.
The clearest named examples are Mr Vegas and Videoslots, which are identified as accepting Siru Mobile deposits. That gives you a practical starting point when looking for casinos that accept Siru Mobile in the UK. It does not establish a universal list of every operator currently offering the service, because payment menus can change independently from the casino’s game catalogue or other account features.
That distinction matters in 2026. A search for Siru Mobile casinos may produce pages that discuss several mobile-payment brands together, but the labels are not interchangeable. Boku, Siru Mobile, and Fonix are different payment routes. MrQ and Duelz are named with Fonix, while Mr Vegas and Videoslots are named with Siru Mobile. Treating all four operators as Siru casinos would therefore give you the wrong answer, even though the services belong to the same broad Pay by Phone category.

Siru Mobile acceptance is limited
Mr Vegas and Videoslots are the named UK operators associated with Siru Mobile acceptance. That is more useful than an invented “best Siru casinos” ranking: the relevant criterion is whether Siru Mobile actually appears in the cashier for your account and chosen market.
A payment method also does not determine which games a casino offers. Siru Mobile concerns how an account may be funded; it says nothing about a particular slot, table game, live casino title or Android-specific game selection. The same applies to bonus claims. A casino may accept a Siru Mobile deposit while applying separate promotional conditions, so the presence of the payment logo should not be read as a promise of a Siru Mobile bonus.
For Android users, the position is no different in principle. An Android casino is not automatically a Siru Mobile casino. What matters is the payment option made available by the operator, not whether the site is opened in an Android browser or through a mobile app. Device compatibility and payment acceptance are separate checks.

Boku has declined, but was not banned by name
Boku has a broader history in UK online casinos, although its availability has been shrinking since 2023. A small number of UK Gambling Commission-licensed casinos still accept Boku deposits, while other operators have removed it, replaced it with Fonix or Siru Mobile, or moved away from Pay by Phone entirely.
This retreat should not be described as a Gambling Commission prohibition on Boku. No specific UK Gambling Commission rule was introduced to ban Boku by name. Individual operators made their own decisions, with compliance risk contributing to the change. That explains why two licensed casinos can take different positions on the same payment service.
A specialist review has named operators including BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino in connection with Boku deposits. The same type of review identifies Jackpot Mobile Casino and Peachy Games as part of the smaller remaining direct-Boku group. These references describe Boku acceptance, not Siru Mobile acceptance, and should not be merged into one list of Siru casinos.

BoyleSports has also been described as adding Boku to its cashier as a UK payment option. That is relevant to Boku’s availability history, but it does not show that BoyleSports accepts Siru Mobile. Payment brands need to be checked separately, however similar their names may look on an affiliate comparison page. Small labels, large consequences.
What “still available” means in practice
For a casino to count as a Siru Mobile option, Siru Mobile must be displayed as an available deposit method for the relevant UK account. A page mentioning mobile payments in general is not enough. Nor is a reference to Boku, Fonix, or a generic Pay by Phone facility proof that Siru Mobile is supported.
The UK market is licensed locally: remote operators serving consumers in Great Britain must hold the relevant UK Gambling Commission licence, regardless of where their key equipment is located. That licensing status is separate from the payment method. A casino can be licensed and offer Boku, Siru Mobile, Fonix, or none of them; the licence does not identify which cashier options are active.
Siru Mobile, Boku, and Fonix are separate Pay by Phone services. A casino accepting one does not automatically accept the others.
The most accurate current picture is therefore narrow. Siru Mobile remains available at named operators such as Mr Vegas and Videoslots, while Boku survives at a small and shrinking group of UK-licensed casinos. Fonix accounts for another part of the Pay by Phone market, including the named examples MrQ and Duelz. These are related alternatives, not one combined service.
If Siru Mobile is the deciding factor, look for Siru Mobile specifically rather than relying on a “mobile payment” label or a list built around Boku. Availability can change, so the operator’s current cashier and UK licence status are the relevant checks before you treat a casino as a Siru Mobile option.

How Pay-by-Mobile Deposits Work—and What They Cannot Do
Pay by Phone is a funding route, not a complete casino banking account. With Boku, the deposit is linked to your mobile number and charged through your mobile network operator. That charge may appear on your phone bill or be taken from available prepaid credit, depending on your mobile arrangement.
The important distinction is between paying into a casino account and receiving money from it. Boku handles the first part only. It cannot be used to send casino winnings back to your phone account.
The Boku deposit process
The exact cashier layout varies between operators, but the transaction follows a clear pattern:
- Open the casino cashier or payments area.
- Select Boku as the deposit method.
- Enter the amount you want to add.
- Provide the mobile number connected to the payment.
- Confirm the transaction with the verification code sent by SMS.
The SMS step links the payment request to your phone. Entering the number alone is not enough; the transaction must also be authorised through the code. Once approved, the casino processes the deposit and adds the funds to your gambling balance.
Boku does not require you to enter card details, and it can be used without connecting a bank account directly to the casino cashier. That is the main practical appeal for someone looking for an alternative to card payments. The cost is routed through the mobile service instead.
A mobile phone is therefore essential. The phone number must be able to receive the confirmation message, and the associated mobile account must be able to accept the charge. If the authorisation fails, the deposit will not be completed. A rejected transaction does not become a withdrawal problem; it simply means the attempted funding has not gone through.
What happens after the deposit
After a successful Boku payment, the money sits in your casino account in the same way as funds added through another accepted deposit method. You can then use the balance for the casino activity permitted by that operator. Boku does not create a separate type of account or change the way the casino records your balance.
The mobile network is involved in charging the deposit, while the casino remains responsible for showing the money in your account. Those are separate parts of the transaction. A mobile bill is not a casino wallet, and the casino cashier is not able to send your balance back through the same route.
That is where many explanations of mobile deposits become too generous. Convenient funding does not mean two-way banking. Boku is deposit-only.
Boku deposit limitations
Boku is a deposit-only service. While it allows you to fund your casino account via your mobile network, it cannot be used to receive casino winnings; you must arrange a separate withdrawal method.
Why you need a separate withdrawal method
Before depositing, arrange a withdrawal option supported by the casino. This might be a debit card, an e-wallet or a bank transfer, subject to the operator’s own verification requirements. The method available to you depends on the casino and on the details it accepts for withdrawals.
If your account later contains winnings, you cannot select Boku and ask the operator to credit them to your phone bill or prepaid balance. The casino must use another approved route. You may also need to complete account checks before a withdrawal is released, so adding a suitable withdrawal method early avoids discovering the limitation after you have already funded the account.
This is the central comparison:
| Function | Boku |
|---|---|
| Add money to a casino account | Yes, where the casino offers Boku |
| Charge the mobile bill or prepaid balance | Yes |
| Confirm a transaction by SMS | Yes |
| Receive casino winnings | No |
| Replace a bank transfer or e-wallet for withdrawals | No |
The table is less exciting than a promise of effortless payments, but it is more useful.
Boku and Siru Mobile are not the same route
Boku and Siru Mobile are separate payment services, even though both can be described as Pay by Phone options. A casino that accepts Siru Mobile does not automatically accept Boku, and a Boku cashier option does not prove that Siru Mobile is available.
The same practical question applies to either service: can it fund the account, and what method will handle withdrawals? For this section, the transaction details above describe Boku. If the cashier displays Siru Mobile instead, read the operator’s payment instructions rather than assuming that the two services have identical conditions.
There is also a possible indirect route. A specialist review has reported that players can fund Neteller with Boku and then use Neteller at casinos that accept it. That arrangement adds an extra payment stage, so it should not be treated as the same thing as depositing directly with Boku. You would need both services to be available and accepted for your account.
Check the cashier before confirming
Payment logos on a general information page are not enough to establish that a method is available to you. Open the casino cashier while logged in and check whether Boku appears as an actual deposit option. If it is listed, follow the displayed instructions for the mobile number and SMS confirmation.
Also check the withdrawal page before sending money. The key question is not merely whether you can get funds into the account, but whether the casino offers a withdrawal route you can use later. A deposit method solves only the funding stage. The rest must be arranged separately.
Check before depositing
- Confirm the casino specifically lists Siru Mobile in the cashier
- Check that you have a suitable withdrawal method arranged
- Verify your UK Gambling Commission licence status
- Ensure you have enough mobile credit or monthly allowance
Paying by Mobile for Slots Does Not Change the Games
Siru Mobile is a payment route, not a slot category. It does not create a separate class of “Siru slots”, alter a game’s rules, or determine which titles appear in a casino lobby. If a casino accepts Siru Mobile, the service is being offered as a way to fund the gambling account. The slots remain the casino’s own games and are selected from the operator’s catalogue.
That distinction matters because phrases such as “Siru Mobile slots” can suggest that Siru operates a special slots site or supplies its own machines. It does neither. You are choosing between a payment option and a game, two separate decisions.
What Siru Mobile actually determines
Siru Mobile can affect whether you are able to add funds using a mobile-based payment option. It does not tell you:
- which slot titles the casino provides;
- whether the casino has a mobile app or only a mobile-friendly website;
- whether a particular game is available on desktop, tablet or phone;
- what features, themes or mechanics a slot contains;
- whether a game is available for free play or real-money play.
The relevant comparison is therefore simple:
| Decision | What it concerns |
|---|---|
| Choosing Siru Mobile | How money is added to the casino account |
| Choosing a slot | Which game you open from the casino lobby |
| Choosing a device | Where you access the casino and its games |
| Choosing free or real-money play | The mode offered by the operator |
“Better” depends on the criterion. Siru Mobile may be the relevant criterion for payment convenience, but it is not a criterion for game quality or selection.
Siru Mobile is not a slot machine
A slot machine is the game itself: its reels, symbols, pay lines or other features are supplied by the casino and its game providers. Siru Mobile sits outside that process. It does not change the outcome, the appearance of the reels or the way a spin is conducted.
This also means that a casino accepting Siru Mobile is not automatically a “Siru slots site”. The operator may offer a broad or narrow selection, and the payment method does not reveal which. You need to inspect the casino’s own lobby for the available games rather than treating the payment brand as a catalogue label.
The same applies to searches for a Siru Mobile slots app. A payment service and a casino application are different products. A casino may provide access through a mobile browser, an app, or both, but Siru Mobile acceptance alone does not establish any of those arrangements.
Payment acceptance does not identify the games
A specialist review has identified Mr Vegas and Videoslots as accepting Siru Mobile, while the same type of material identifies MrQ and Duelz with Fonix. That information describes payment arrangements, not a shared set of games. It should not be read as proof that every one of these operators offers the same slots or that Siru Mobile works across every casino site.
The practical check is to separate the questions:
- Does the casino accept Siru Mobile as a payment option?
- Does the casino offer the slot or game you want?
- Can you access that game on your chosen device?
- Do the casino’s terms permit the type of play you intend?
A “yes” to the first question does not answer the other three.
What about free Siru Mobile slots?
There is no special category of free slots funded or supplied by Siru Mobile. Free-play availability is controlled by the casino and the individual game. If a casino offers a demonstration mode, that is a feature of the operator or game provider, not of the payment method.
Conversely, if you choose real-money play, Siru Mobile remains relevant only to the account-funding side. Boku illustrates the same separation: it is a deposit-only method and cannot receive casino funds when you withdraw. Payment technology does not become part of the game once the account has been funded.
So, when assessing online slots with Siru Mobile in the UK, use two separate criteria: the casino’s current payment options and the casino’s actual game lobby. One concerns access to funds; the other concerns what you can play. Mixing them produces a neat label, but not useful information.
Separate Functions
Siru Mobile is a method for adding funds and has no influence on the types of slots or games available to you.
Which Casinos Accept Pay-by-Mobile Deposits?
The UK market now has a narrow and divided Pay by Phone offering. A casino may support Boku, Fonix or Siru Mobile, but those names are not interchangeable. Seeing one mobile-payment brand in a cashier does not mean that the others are available there.
A specialist review identified Jackpot Mobile Casino and Peachy Games among the remaining sites accepting direct Boku deposits. They belong to the shrinking group where Boku itself is the payment option. That distinction matters: funding an account through Boku is not the same as finding a casino that accepts Siru Mobile.
The confirmed operator and payment-method pairings are:
| Operator | Pay-by-mobile method identified |
|---|---|
| Jackpot Mobile Casino | Boku |
| Peachy Games | Boku |
| MrQ | Fonix |
| Duelz | Fonix |
| Mr Vegas | Siru Mobile |
| Videoslots | Siru Mobile |
The pairings above were reported in a specialist review, so they should be treated as dated availability rather than a permanent directory. Payment menus can change when an operator alters its providers or removes a mobile-payment route. Before registering or depositing, check the cashier for the exact method you intend to use.
Siru Mobile acceptance
For people specifically looking for Siru Mobile casinos, the named operators are Mr Vegas and Videoslots. That does not turn every operator offering Pay by Phone into a Siru casino: MrQ and Duelz are associated with Fonix, while Jackpot Mobile Casino and Peachy Games are associated with Boku.
This also explains why a broad list of “mobile casinos” can be misleading. A list may combine several payment brands under one label, even though your phone account can only be used where the casino has enabled the particular provider. The useful criterion is therefore the payment method shown by the operator, not simply whether the site advertises mobile deposits.
What the named operators do not establish
The presence of Siru Mobile at Mr Vegas or Videoslots does not establish that either operator offers a no-deposit promotion, free spins, or a bonus without wagering conditions. Payment acceptance and promotional eligibility are separate matters. A casino can accept a Pay by Phone deposit while applying different rules to its welcome offer.
Likewise, “Siru Mobile card” is not a separate casino category. Siru Mobile is the payment route; the casino remains the place where the account and gambling activity are provided. You should match the operator to the method displayed in its cashier and read the applicable payment and promotion terms before committing funds.
Siru Mobile
Available at operators like Mr Vegas and Videoslots.
Fonix
Associated with operators such as MrQ and Duelz.
Boku
Found at sites like Jackpot Mobile Casino and Peachy Games.
The practical comparison is simple: choose Mr Vegas or Videoslots when the deciding criterion is a named Siru Mobile option; consider MrQ or Duelz when Fonix is the available route; and look to Jackpot Mobile Casino or Peachy Games when direct Boku acceptance is what you need. Availability, not branding, decides the result.
Real-Money Play, Deposits and Withdrawals
Paying by phone can be used to put money into a casino account for real-money play. It does not create a separate category of “mobile slots”, and it does not change the cash value of any winnings. The payment method only describes how funds reach your balance; the games and the account balance remain governed by the casino’s rules.
The important distinction is between funding an account and receiving money from it. Boku is a deposit-only service. You can use it to add funds to an eligible casino account, but you cannot select Boku as the destination when withdrawing casino funds. A Boku deposit therefore solves the first part of the transaction, not the second.
That matters if you are looking for real-money slots using Siru Mobile or another Pay by Phone option. Before depositing, you need to arrange a separate withdrawal method supported by the casino. Depending on the operator, that may be a debit card, an e-wallet or a bank transfer. The suitable choice depends on the methods available in your account, not simply on the fact that the original deposit was made from your phone.

What the payment route does—and does not—mean
A mobile-funded balance can be used for real-money play in the same way as money added through another accepted deposit route. However, the payment method does not guarantee that every game is available, that every promotion applies, or that withdrawals will follow the same route. Those are separate account and operator conditions.
It is also worth keeping the names separate. Siru Mobile and Boku are not interchangeable labels for one service. If a casino displays Siru Mobile as its Pay by Phone option, that does not mean Boku is available there, and a Boku cashier entry does not confirm Siru acceptance. Check the exact method shown in the casino cashier before treating a site as suitable for your intended deposit.
For a real-money session, the practical checklist is short:
- confirm that the casino accepts the specific mobile payment service you intend to use;
- make sure the account can receive withdrawals through another supported method;
- review the casino’s rules for deposits, play and withdrawals before committing funds;
- use only funds you can afford to lose.
A successful deposit is not proof that a withdrawal method has been arranged. That is the detail most easily skipped—and the one that becomes relevant when the balance turns into winnings. Phone payment handles entry, not exit.
Deposit Limits, Phone Bills and PAYG Balance
When you compare Pay by Phone options at UK casinos, separate three different limits: the amount shown by the payment service, the restriction applied by the mobile network, and any control set by the operator. They can point in different directions, so a failed deposit does not automatically mean that the casino has removed the method.
The commonly quoted UK Boku figure is £30 for one transaction. A specialist review gives a different practical range, stating that some casinos or mobile networks may permit £40 or £50 instead. Treat those higher figures as conditional, not as a market-wide entitlement. The amount available to you depends on the live rules attached to your phone account and the casino cashier.
Deposit Limits
Attention Mobile network caps and daily allowances are enforced by your provider, not just the casino, which may cause transactions to fail.
There is also a direct disagreement about the network-level cap. One account describes Boku as allowing about £10 per transaction and £30 per day. Another version gives £30 per day but does not specify a separate per-transaction ceiling. That distinction matters: a daily allowance does not tell you how many separate payments, or what size of payment, the network will approve. Check the amount displayed when you select Boku rather than relying on an old guide.
A further point attributed to a specialist review is that the daily Boku allowance is enforced by the mobile network rather than by the casino. The operator still controls whether Boku appears in its cashier and may apply its own deposit controls, but a network-level ceiling can stop the payment even when the casino account itself would accept more. A casino cashier is not a magic override.
Monthly bill or PAYG credit?
With a monthly mobile contract, an approved Boku payment is added to the bill issued by your network. Your available spending can therefore be affected by the network’s account rules, alongside the Boku and casino restrictions. The phone bill is the charging route, not an extra deposit allowance.
Casinos That Accept Monzo UK: Payment Options
With a PAYG plan, the payment comes from your remaining prepaid balance. A specialist review states that you cannot deposit more than that balance; the payment is declined when the credit is insufficient. In practice, a network cap and your available credit work together: the lower effective amount is the one that matters.
This is separate from paying with a credit card or debit card. Boku charges the mobile account, while the mobile network decides whether the account can support the transaction. If Siru Mobile is listed instead, read its displayed limits independently; Boku figures should not be presented as Siru’s guaranteed terms.
Alternatives When Siru Mobile Is Not Available
If Siru Mobile is missing from a casino cashier, the most suitable replacement depends on the operator’s accepted payment methods. There is no single winner: Fonix is useful where the casino has integrated Fonix, while Boku offers an additional route through Neteller.
DO
- Check the specific mobile provider in the cashier
- Arrange a separate withdrawal method early
- Verify the UKGC licence status
DON’T
- Assume Boku and Siru Mobile are interchangeable
- Rely on general ‘mobile payment’ labels
- Expect to withdraw winnings via your phone bill
Fonix as a direct pay-by-phone option
MrQ and Duelz are the named operators associated with Fonix. This makes Fonix the more relevant alternative when you want to charge a deposit to your mobile service but the casino does not offer Siru. Fonix and other pay-by-phone services are supported by EE, O2, Vodafone and Three, so network compatibility is broad. It still does not make every casino accessible; the operator must list Fonix in its cashier.
Siru at other operators
Siru Mobile remains a direct option at Mr Vegas and Videoslots, according to a specialist review. If either operator accepts your registration and displays Siru when you choose a payment method, switching casino may be simpler than looking for a replacement service. This is an operator-specific distinction, not evidence that Siru is available throughout the UK market.
The practical comparison is therefore:
| Route | What it offers | Where the named acceptance applies |
|---|---|---|
| Fonix | Direct pay-by-phone funding | MrQ and Duelz |
| Siru Mobile | Direct pay-by-phone funding | Mr Vegas and Videoslots |
| Boku through Neteller | Funds Neteller, which can then be used at casinos accepting Neteller | Depends on Neteller acceptance at the casino |
Boku through Neteller
Boku provides a different workaround. Rather than paying the casino directly, you can use Boku to fund Neteller and then choose a casino that accepts Neteller deposits. This widens the range of possible destinations, but adds an intermediary and depends on both services being available to you. It is therefore more flexible by reach, while Fonix and Siru are more direct when shown in the casino cashier.
For a casino offering only one of these methods, that payment-method match is the deciding criterion. Check the cashier before registering or setting aside funds: a service being supported by your mobile network does not mean every operator accepts it. Pay by phone is convenient only when the route exists at both ends.
Minimum Deposits and the Amount You Can Pay at Once
The minimum deposit depends on the payment method shown in the cashier. A casino accepting Siru Mobile does not necessarily use the same denominations or limits as a casino offering Boku. Therefore, a search for a £5 Siru Mobile deposit casino should not be treated as evidence that £5 is available through every Pay by Phone option.
Casinos That Accept AstroPay in the UK: What to Check
For Boku, one specialist review reports deposits in amounts divisible by ten, such as £10, £20 and £30. On that account, a £5 deposit would not be available, even if the casino’s general minimum deposit were lower. The restriction concerns the available payment denominations rather than the games or the player’s chosen stake.
Published figures for Boku also disagree. One account gives a minimum of €10, a maximum of €30 and a monthly limit of €240. Another UK-focused account describes £30 as the standard maximum for one transaction, while allowing that some operators may support £40 or £50. These figures should not be merged into one supposed universal schedule: the cashier, operator and payment arrangement determine what you can select at the time.
The practical distinction is simple:
- Minimum: a stated Boku account gives €10; another description of Boku denominations starts at £10.
- Available amounts: a specialist review says the selectable Boku deposits are divisible by ten, including £10, £20 and £30.
- Maximum in one payment: published accounts differ between €30 and £30, with some operators reported as allowing £40 or £50.
- PAYG restriction: a prepaid user cannot submit a Boku payment worth more than the remaining phone balance, according to a specialist review.
That last condition can make the usable minimum higher in practice. If your remaining PAYG credit is below the denomination offered by the cashier, the transaction cannot proceed, regardless of the casino’s advertised minimum. Monthly-billed customers avoid that particular balance test, but the available Boku denominations and the operator’s own cashier settings still apply.
Siru Mobile should be checked separately. A Boku denomination rule is not proof of a Siru Mobile minimum, and neither method establishes whether a site is connected to GamStop. Before depositing, open the cashier, select the named Pay by Phone method and confirm the exact amount displayed. Small print matters.
Check the Licence; a Payment Method Does Not Prove GamStop Status
Siru Mobile is a payment option, not a regulatory category. Seeing it in a casino cashier does not show whether the operator is connected to GamStop, accepts customers who are registered with GamStop, or has any particular self-exclusion arrangement. The same point applies to searches for Siru Mobile slots or casinos described as “not on GamStop”: the payment method alone cannot establish that status.
Is Siru Mobile a slot provider?
No, Siru Mobile is purely a payment route for funding accounts and does not supply or change any slot games.
Can I use Boku to withdraw money?
No, Boku is a deposit-only service and cannot be used to send winnings back to your mobile account.
Does a mobile deposit guarantee a bonus?
Not necessarily; you must check the specific terms to see if your chosen payment method is eligible for the promotion.
The practical check is the operator’s licence. Gambling offered online to consumers in Great Britain is regulated by the UK Gambling Commission, and remote operators must hold the relevant licence even when their technical equipment is located elsewhere. Location is therefore not a substitute for licensing. A casino’s branding, payment menu or mobile-billing option does not replace that regulatory requirement.
Before depositing, look for the operator’s UK Gambling Commission licence details and confirm the licence number on the Commission’s public register. The regulator is the sole authority for commercial gambling in Great Britain. It grants operating licences to gambling businesses and personal licences to certain individuals involved in running them. For you, the important distinction is the business’s operating licence: that is the authorisation relevant to a casino offering real-money gambling.
A valid licence also places the operator within the British regulatory framework. UK-licensed casinos must provide responsible-gambling tools, including self-exclusion, and must have an internal complaints process with access to an approved Alternative Dispute Resolution service. Those obligations are more meaningful checks than the presence of Pay by Phone at the cashier.
If the operator cannot be matched to a current UK Gambling Commission entry, treat the site as outside the UKGC licensing system rather than assuming that Siru Mobile makes it suitable for British play. An offshore licence, where one exists, is not a UK Gambling Commission licence.
The criterion is clear: use licensing to assess regulatory status, and treat GamStop status as a separate question. Do not infer one from the other. That distinction matters.
Welcome Bonuses and Pay-by-Mobile Deposits
A Pay by Phone deposit does not automatically qualify for a welcome offer. Bonus rules are set by each casino, so the payment method and the promotion must be checked together. This matters when you are looking for Siru Mobile casinos offering real-money play, because a cashier may accept the payment while the bonus terms exclude it.
Casinos That Accept Zimpler in the UK: What to Check · Casinos That Accept WebMoney in the UK: Payment Guide
A specialist review identifies MrQ, Duelz, Mr Vegas and Videoslots as operators where pay-by-phone deposits are accepted for bonus eligibility. That is a useful comparison point, not a permanent guarantee: offers and payment rules can change, so read the current promotion page before making the qualifying deposit. The deciding criterion is eligibility, not simply whether Siru Mobile or another phone-billing option appears in the cashier.
The same check applies to searches for a Siru Mobile slots bonus or a no-deposit bonus. A no-deposit promotion is not implied by the availability of Pay by Phone, and a deposit-based offer may require a qualifying payment method. If the terms mention cards, wallets or particular deposit routes, do not assume that a mobile-billed payment is included.
For context, a specialist review describes a common UK welcome-offer structure as a deposit match worth 100% of the qualifying amount, capped at £100, with wagering set at 35 times the bonus. That is an example of the kind of condition you may encounter, rather than a standard attached to every Siru-accepting casino. The amount matched, qualifying deposit, games that count and wagering calculation all depend on the operator’s wording.
Time limits are equally important. The same type of review states that bonus funds expire after 30 days, while bonus spins expire after 72 hours. Treat those periods as promotion-specific conditions and confirm them in the live terms. A missed deadline can remove the bonus even when the original deposit met the payment requirement.
Read the bonus terms before paying by phone, checking four points: whether the method qualifies, what must be wagered, which games count and when the reward expires. That small comparison prevents a payment method from being mistaken for a bonus entitlement.
What are the deposit limits at pay by mobile casinos?
Boku’s standard UK limit is £30 per transaction, although some casinos or networks may allow £40 or £50. Network-level limits can be about £10 per transaction and £30 per day; PAYG deposits are also capped by 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, though availability has declined since 2023. It was not banned by the UK Gambling Commission by name; individual operators made their own decisions to drop it.
How can I be sure Boku is available where I live?
Check whether Boku appears as a deposit option in the cashier for your UK casino account, and confirm that your mobile network supports pay-by-mobile payments. EE, O2, Vodafone and Three support pay by mobile and Fonix.
Can I deposit by phone bill without Boku?
Yes. Siru Mobile and Fonix are other pay-by-phone options, though availability depends on the casino; check its cashier for the specific method.
What is the standard Boku deposit limit in the UK?
The standard limit is £30 per transaction. Some casinos or mobile networks may allow up to £40 or £50.
