Siru Mobile is a deposit route, not a casino licence, and availability can depend on operator arrangements and supported networks.
Where Siru Mobile Fits in the UK Casino Payment Market
Siru Mobile sits within the Pay by Phone part of the UK casino payment market. It is not a casino licence, a gambling product, or a catalogue of games. It is a payment option that may appear in an operator’s cashier when the casino and the payment provider support that route.
The most specific operator information currently associated with Siru Mobile names Mr Vegas and Videoslots. A specialist casino review identifies both as casinos accepting Siru Mobile deposits. That makes them useful names to check, but it does not turn them into a complete list of every Siru Mobile casino available to British players. Payment menus can change, and an option shown to one customer may depend on the operator’s current arrangements, account status, or supported mobile network.
This distinction matters when looking for all Siru Mobile casinos in the UK. A short list of named operators is not the same as a permanent market directory. It is safer to treat Mr Vegas and Videoslots as reported examples, then inspect the cashier and licence details of any operator before depositing. The same approach applies whether you are using an Android phone or another device: the handset does not by itself create Siru Mobile support. The casino must offer Siru Mobile as a payment option, and the relevant payment route must be available to you.
Siru Mobile, Boku and Fonix are separate options
Pay by Phone availability in Britain has changed as operators have reviewed their payment arrangements. Boku, Fonix and Siru Mobile should not be treated as different names for one identical service. They are separate payment methods, so a cashier offering one does not automatically offer the others.
The reported operator pattern illustrates the difference. MrQ and Duelz are associated with Fonix, whereas Mr Vegas and Videoslots are associated with Siru Mobile. Other operators may retain Boku, remove Pay by Phone altogether, or use a different provider. Since 2023, the number of operators accepting Boku has been shrinking, while some casinos have moved towards Fonix or Siru Mobile.

A specialist casino review also reports a small group of UKGC-licensed casinos still accepting Boku, including BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino. That is a Boku reference point, not a Siru Mobile list. It should not be used to infer that every named operator accepts Siru Mobile, or that every operator offering Boku also offers Siru Mobile.
There was no UK Gambling Commission rule specifically banning Boku. Individual operators moved away from it because of compliance risk. That explains why the payment market can narrow without a named prohibition applying to the method itself. It also explains why an older casino article or an old cashier screenshot may no longer describe the payment choices available when you open an account.
The UK licensing boundary
Payment acceptance does not replace gambling licensing. The UK Gambling Commission regulates commercial gambling in Great Britain, including remote gambling offered to consumers there. Its jurisdiction applies to the gambling service rather than depending on where the operator’s key equipment is located. A business offering remote gambling to British consumers therefore needs the relevant Gambling Commission operating licence, and individuals involved in operating gambling businesses may require personal licences.
For you, the practical test is whether the casino has a current UK Gambling Commission operating licence for the service it provides. Check the operator in the Commission’s public register before depositing. A Pay by Phone logo, a Siru Mobile button, or a statement that an operator accepts mobile deposits does not prove that the gambling service is licensed.
This is also why “best Siru Mobile casino” cannot be decided from the payment method alone. Siru Mobile tells you how a deposit may be funded; it does not establish the operator’s current licence position, the quality of its terms, or whether the payment option remains active. The relevant question is whether the casino is legally permitted to serve British customers and whether Siru Mobile is actually available in its cashier at the time you use it.
UK Licensing
The UK Gambling Commission regulates commercial gambling in Great Britain. A business offering remote gambling to British consumers needs a relevant Gambling Commission operating licence. You should check the operator in the Commission’s public register before depositing.
The UK Gambling Commission is the sole regulator for commercial gambling in Great Britain. Its role covers the operator’s authorisation to provide gambling services, while the payment provider handles the payment channel. Those are separate layers. A casino can change its payment providers without changing its licence, and a payment method can appear across different operators without licensing the gambling activity itself.
For that reason, the names connected with Siru Mobile should be read as reported operator examples rather than as a guaranteed, complete or permanent directory. Verify the licence, sign in to the casino’s cashier, and confirm that Siru Mobile is displayed for your account before treating the operator as an available Siru Mobile casino.
Why Casino Cashiers May Offer Boku, Fonix or Siru Instead
A casino cashier does not have to keep the same Pay by Phone provider indefinitely. The payment option shown to you depends on agreements between the operator, the payment service and the mobile networks involved. If one arrangement is withdrawn, a casino may replace it with another service, or remove mobile billing altogether.
That is the reported direction of travel in the UK casino market since 2023. A specialist review describes operators moving away from Boku and turning instead to Fonix, Siru Mobile, or no Pay by Phone option. This is a market change, not a UK Gambling Commission rule that names Boku and prohibits it. Individual operators have made their own decisions, including decisions connected with compliance risk.
Casinos that accept Solana in the UK: what to check
The result is that an older list of casinos accepting Boku may no longer describe what a cashier offers when you register or return to an existing account. A casino may remain in an article as a Boku site while its current cashier displays a different option. Conversely, a casino that has removed Boku may still support another form of Pay by Phone.
Boku is not a general name for every mobile payment
Boku is one particular payment method. Its role is to charge a deposit to your mobile service, rather than to treat every mobile-based option as if it were the same product. The cashier must specifically support Boku for that route to be available.
A specialist review has listed BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino as accepting Boku deposits. That list should be read as a reported set of operator-method pairings, not as proof that every named cashier still offers Boku at the time you use it. Payment arrangements can change, and a casino can present different methods to different customers or in different account areas.
The important distinction is therefore between the casino and the method. A casino name alone does not tell you whether Boku is available. The payment label in the cashier is the relevant detail.
What changes when a casino moves to Fonix
Fonix is another named route in the Pay by Phone landscape, but it should not be treated as a new name for Boku. A casino replacing Boku with Fonix has changed its payment-provider arrangement. You cannot infer that a Boku deposit will work simply because Fonix is displayed, or that a casino offering Boku must also offer Fonix.
Network Support
Pay by Phone services like Fonix have been associated with the main UK mobile networks: EE, O2, Vodafone and Three.
Pay by Phone services and Fonix have been associated with the main UK mobile networks: EE, O2, Vodafone and Three. Network support is only one part of the chain. The mobile network may support the service while a particular casino chooses not to enable it. The reverse assumption is also unsafe: seeing a familiar network on your phone does not establish that the casino’s selected provider is available to you.
This explains why two UK casino cashiers can show different mobile-payment choices even when you use the same network. The operator selects which payment services to integrate, while the network determines whether the relevant mobile-billing route can be used. These are separate dependencies.
Where Siru Mobile fits
Siru Mobile is a further alternative that appeared as operators moved away from Boku. It is not interchangeable with either Boku or Fonix. A casino that accepts Siru Mobile has made a specific choice to support that service; the choice does not create a general right to use any other mobile-payment brand there.
These associations are subject to change, so the method currently shown in the cashier matters more than an old description of the operator.
Casinos That Accept AstroPay in the UK: Payment Guide
This also answers the practical question of whether you can use Siru Mobile at a UK online casino: you can do so where the operator expressly offers Siru Mobile as a payment choice and the service is available to your mobile account. A casino offering Boku is not automatically a Siru Mobile casino, and a casino offering Fonix is not automatically one either.
Why the cashier can look different from an old casino list
Payment-method lists age quickly because they record a commercial arrangement, not a permanent casino feature. The reported Boku list includes many recognisable operators, but the same market reporting says that the number of UK-licensed casinos accepting Boku has been shrinking since 2023. An operator may therefore appear in older material under Boku while its current payment menu has moved to Fonix, Siru Mobile or no mobile option.
You should treat each provider as a separate route:
- Boku is the established payment brand that some casino operators have retained.
- Fonix is a different mobile-payment service used by some operators as Boku availability declined.
- Siru Mobile is another distinct replacement route, offered by particular casinos rather than by every operator that once accepted Boku.
The useful comparison is not which brand sounds most similar. It is whether the exact provider appears in the casino cashier, whether your mobile network supports that route, and whether the operator still maintains the arrangement. That is why a current payment-method check is more reliable than assuming that an old Boku acceptance list also covers Fonix or Siru Mobile.
What a Mobile-Paid Deposit Does—and Does Not—Tell You About Slots
A casino accepting Siru Mobile tells you how money can be added to your gambling balance. It does not tell you which slot games are available after you log in. The payment method and the game catalogue are separate parts of the operator’s system.
For example, a specialist casino review identifies Mr Vegas and Videoslots as accepting Siru Mobile. That payment detail may help you decide whether either cashier suits your needs, but it does not turn every game on those sites into a “Siru Mobile slot”. The same games may be available to customers who deposit by another method, provided the operator offers them and your account can access them.
Slot Information
Siru Mobile is a funding method, not a game provider, and does not determine slot content or features.
The term Siru Mobile slots is therefore best understood as a shorthand for slots played at a casino where Siru Mobile can be used for funding. Siru Mobile is not the game provider, does not create the reels or bonus features, and does not determine a slot’s return, volatility, theme or rules. A casino may offer a large selection of games while accepting Siru Mobile, but the payment option itself supplies no information about the contents of that selection.
Separate the cashier from the game lobby
The cashier handles financial operations such as deposits. The game lobby handles the titles available for play. These systems can be connected to the same account without one controlling the other.
When you see Siru Mobile listed beside a deposit option, it answers a narrow question: can this operator accept that payment route at the point of funding? It does not answer any of the following:
- which slot titles the casino carries;
- which software providers supply those titles;
- whether a particular slot is available on mobile;
- whether a game can be played for free before depositing;
- what a slot’s return or volatility is;
- whether a game has progressive features or a specific bonus round.
Those details belong to the individual game description and the casino’s own lobby. Check the title’s information panel and the operator’s terms rather than inferring anything from the logo or name of the payment service.
The distinction also applies when comparing operators. MrQ and Duelz are identified with Fonix, whereas Mr Vegas and Videoslots are identified with Siru Mobile in a specialist review. That difference describes their listed Pay by Phone arrangements; it does not establish that one operator has better slots, a different slot catalogue, or special games designed for its chosen payment provider.
Mobile access does not create a separate game type
Searching for online slots that accept Siru Mobile can suggest that the payment method and the game are a combined product. Technically, they are not. A slot is supplied and operated within the casino platform, while the payment service is used to move funds into the account.
Casinos That Accept Ethereum in the UK: Payment Checks
The same principle applies to a casino’s mobile website or app. If a casino allows Siru Mobile deposits through a mobile interface, that does not mean it offers a separate “Siru Mobile slots app”. The app or mobile site is the access layer; Siru Mobile is the funding route. Game availability can still depend on the operator’s software, account status and device support.
A free-play version must also be treated separately. A demo game, where offered, does not require the same funding route as real-money play. Siru Mobile acceptance does not prove that a particular slot has a free version, and finding a free version does not prove that Siru Mobile can fund real-money play at the site hosting it.
What to verify for a particular slot
If you have a specific game in mind, inspect the casino’s lobby and the game’s information before depositing. Confirm that the title is listed, that it opens on your device, and that its real-money rules are displayed. Then check the cashier separately for Siru Mobile availability.
Slot Verification
- Confirm the slot title is listed in the lobby
- Ensure the game opens on your device
- Check the game’s information panel for rules and volatility
- Verify Siru Mobile availability in the cashier
For a UK player, “legitimate” should also be assessed independently of the payment badge. A legal online casino serving Great Britain must hold a current UK Gambling Commission operating licence, and you should verify the licence on the Commission’s public register before depositing. The presence of Siru Mobile in a cashier does not replace that check, and it does not certify any individual slot.
How a Boku Deposit Is Entered and Confirmed
A Boku deposit is entered through the casino’s cashier rather than through the game itself. First, sign in to the gambling account and open the deposit area. The cashier displays the payment methods currently enabled for that account and jurisdiction. Select Boku if it is shown. Its presence in one casino’s cashier does not prove that Siru Mobile follows the same process, so do not treat the Boku sequence as instructions for a Siru Mobile payment.
Before entering payment details, check that the casino is authorised for the British market. The UK Gambling Commission’s public register is the relevant place to verify the operator’s current licence. The cashier should also show the operator’s own payment and deposit terms. These can determine whether a particular mobile payment is available to you, even when the method is described elsewhere as supported.
Entering the deposit
After selecting Boku, the cashier asks for the amount you want to deposit and the mobile phone number connected with the payment. Enter the number carefully: the transaction is linked to that mobile account, not merely to the casino username. The amount is then passed to Boku for confirmation.
Casinos That Accept Zimpler in the UK: Payment Checks
A specialist review reported that Boku amounts were offered only in increments of ten, with £10, £20 and £30 given as examples. Treat that as a reported checkout condition rather than a permanent rule for every casino. The available buttons, the amount field and any message shown by the cashier are the controls that determine what can be submitted at that time.
Once the amount and phone number are entered, submit the request. Boku sends an SMS verification code to the supplied number. Retrieve the code and enter it in the confirmation field displayed by the payment screen. This step connects the approval to possession of the mobile phone and prevents the deposit from being completed solely by entering a number.
The payment is confirmed only after the code is accepted. If the number is mistyped, the SMS does not arrive, or the code is entered incorrectly, the request may not complete. In that situation, check the number and the cashier message before submitting another request, so that you do not create duplicate pending attempts.
The account balance should change only after the cashier reports that the transaction has been accepted. If the screen shows a pending or failed status, rely on that status rather than assuming that the funds have arrived. Keep the casino’s transaction reference or confirmation message until the balance is correct and the payment is visible in the account history.
Boku Deposit
Step 1: Selection
Sign in to your account and select Boku in the cashier area.
Step 2: Details
Enter the deposit amount and the mobile phone number connected to the payment.
Step 3: Verification
Retrieve the SMS verification code sent to your phone and enter it into the confirmation field.
This procedure describes a Boku deposit: choose Boku, specify the amount, provide the mobile number and approve the request with the SMS code. It does not establish how a Siru Mobile cashier works, what fields it requests or how it confirms a payment. A casino accepting Siru Mobile may present a different sequence, and the applicable instructions are those displayed by that operator at the time of deposit.
Real-Money Play Requires a Separate Withdrawal Route
A mobile payment option can solve one part of the gambling account lifecycle without solving the other. Boku is used to put money into an online casino account, but it is a deposit-only method. Casino funds cannot be withdrawn to Boku.
This distinction matters when you are looking for real-money slots using a mobile payment method. A successful Pay by Phone deposit means that the casino can receive your payment through that route. It does not mean that the same route can receive winnings later. The cashier treats the two operations differently: depositing transfers money into the gambling account, while withdrawing sends eligible funds from that account to a supported payout method.
What you need before depositing
You should register a separate withdrawal method before relying on Boku to fund play. This may be a debit card, an e-wallet or a bank transfer, provided the casino supports it for withdrawals and the account passes the operator’s checks. The available options are determined by the casino’s cashier, not by Boku.
Casinos That Accept Giropay in the UK: What to Check
This is the key point for searches such as “online slots pay by Siru Mobile” or “Siru Mobile slots real money UK”. A payment label describes how you fund the account. It does not, by itself, describe the casino’s full payment system, its payout options or the conditions attached to cashing out. You need to inspect the withdrawal section separately rather than assuming that a mobile-funded account can be paid back to a phone bill or mobile balance.
The same principle applies if you are considering a bonus connected with a mobile deposit. Funding the account and receiving a withdrawal are separate events, and the payment route used for the first event does not determine the route available for the second. Keep the withdrawal requirement in view before you commit money to play.
How the money-out route affects your decision
If you win while playing slots for real money, the balance remains inside the casino account until you request a withdrawal through an accepted route. Boku cannot be selected as the destination for those funds. A casino may therefore accept Boku for deposits while requiring you to use another method for withdrawals.
Check that the intended casino has a current UK Gambling Commission licence before depositing, and confirm the available withdrawal methods in its cashier or payment terms. This is not a technical detail to resolve after a win. If the only method you planned to use was Boku, it is not sufficient for the complete journey from payment to payout.
Phone-Bill and PAYG Charges: Where the Money Comes From
A Pay by Phone deposit with Boku uses your mobile account as the funding source. It does not draw money directly from a casino wallet, and it is not the same as paying by debit card or credit card. Boku charges the mobile network account connected to the number entered during the payment process.
Billing Sources
For contract customers, the charge is added to the regular mobile phone bill. For PAYG customers, the amount is taken from existing prepaid credit.
For a contract customer, the charge is added to the regular mobile phone bill. The casino receives the deposit through Boku, while the cost is collected by the network operator as part of the customer’s billing arrangement. The transaction therefore affects the amount payable on the next bill rather than reducing the balance of a bank account at the moment of deposit.
PAYG works differently. There is no later monthly bill to settle. Instead, the Boku payment is taken from the prepaid credit already available on the mobile account. The amount you can fund is consequently limited by the balance remaining on that account. If the available PAYG credit is insufficient, the payment cannot be completed for an amount greater than the balance.
This restriction belongs to the source of the money, not to the casino’s game balance. A casino may display a deposit option, but Boku still has to obtain authorisation from the mobile account. A positive casino balance does not create additional PAYG credit, and winnings held by the casino cannot be treated as mobile credit for a later Boku payment.
Casinos that accept Litecoin in the UK: payment checks
A specialist review reports the PAYG rule as a direct balance constraint: a prepaid customer cannot deposit more through Boku than the remaining phone balance. Because mobile tariffs and payment arrangements can change, you should treat the available balance shown by your network as the controlling practical limit for that transaction.
This is also why searches for Siru Mobile casino deposits, mobile-funded slots or casinos described as accepting mobile credit can produce misleading comparisons. Boku, Siru Mobile and other Pay by Phone services are separate payment methods. A statement about Boku being charged to a bill or deducted from PAYG credit does not establish that Siru Mobile uses the same billing arrangement. Check which method is named in the casino cashier and identify whether the charge will reach a monthly bill or reduce prepaid credit before you confirm the payment.
Using a Different Payment Route When Mobile Billing Is Unavailable
If Siru Mobile or another mobile-billing option is unavailable at checkout, the first alternative to examine is another Pay by Phone service. Pay by mobile and Fonix are supported by the four major UK mobile networks: EE, O2, Vodafone and Three. This support concerns the mobile network route, not automatic acceptance by every casino. The casino must also offer the relevant payment method in its cashier.
Do
- Check if your network supports the specific provider
- Verify the casino offers the method in their cashier
Don’t
- Assume a network’s support automatically means the casino enables it
- Assume Boku availability guarantees Fonix or Siru Mobile availability
That creates two separate checks. Your network may support Pay by Phone or Fonix, while the casino may show only one of them, or neither. A payment option can therefore be unavailable because of the network connected to your number, because the operator has removed it, or because the casino does not accept that particular route. The cashier is the practical point at which these conditions meet.
Using Boku through Neteller
Another route described in a specialist review is to use Boku to fund a Neteller account and then use Neteller to deposit at a casino that accepts Neteller. In this arrangement, Boku is used before the casino transaction rather than selected directly in the casino cashier. Neteller becomes the payment method presented to the casino.
This is not the same as direct Siru Mobile or direct Pay by Phone funding. It adds an intermediate account, so you need to confirm both parts independently:
- whether Boku can be used to add funds to Neteller;
- whether the chosen casino accepts Neteller deposits.
Acceptance at one stage does not prove acceptance at the other. A casino that accepts Neteller may not offer Boku directly, while a casino that displays Boku may not be the right destination for a Neteller-funded balance.
Before choosing this route, check the available methods in the relevant Neteller account and the casino cashier. Payment menus can differ between operators and can change, so an old description of a mobile-payment route should not be treated as confirmation that it remains active. You should also verify that the casino holds a current UK Gambling Commission operating licence before depositing. These checks help distinguish a working payment path from a method that is merely listed in an outdated description.
How Boku Deposit Caps Are Set
A Boku deposit has two separate constraints: the amount allowed in one transaction and the total allowed during a day. These limits belong to Boku’s payment arrangement and the mobile network behind it. They do not describe Siru Mobile, and they do not confirm that a casino offering Siru will accept a particular minimum deposit.
The figures reported for Boku are not consistent. One specialist review gives £30 per transaction as the standard UK limit, while saying that some casinos or network operators may permit £40 or £50. Another account describes a different structure: £10 per transaction and £30 per day at network level. A further version states £30 per day without specifying a per-transaction ceiling. These reports cannot be merged into one fixed rule, because the applicable cap can depend on the operator, the network and the current payment arrangement.
Casinos That Accept Maestro in the UK: What to Check
The practical point is that a casino cashier may display an amount that the mobile operator will still reject. The daily ceiling is enforced by the mobile operator rather than by the casino. If your network has already counted earlier Boku payments towards that day’s allowance, a new deposit can fail even when the casino account and cashier otherwise allow it. The reverse can also occur: a casino may impose a lower cashier limit than the network’s maximum.
Treat any stated cap as a condition to verify at the point of deposit, not as a permanent property of every Boku account. A specialist review has also reported that some limits change over time, so a figure shown in older payment guidance may not match the amount currently accepted by your network or the individual casino.
This distinction matters when comparing mobile-payment options. Searching for UK casinos with a small Siru Mobile deposit does not turn Boku’s reported caps into Siru limits. Siru acceptance, the minimum shown by a casino, and the maximum permitted by a mobile operator are separate pieces of information. Check the cashier and the relevant network conditions before treating a displayed amount as available to you.
Deposit Limits
Attention Boku deposit limits (such as daily or per-transaction caps) are enforced by the mobile operator and may differ from casino limits.
What to Check Before Relying on a Non-GamStop Claim
A Siru Mobile payment option and GamStop status are separate pieces of information. Seeing Siru Mobile in a cashier tells you how a deposit may be funded; it does not show whether the operator participates in GamStop, whether it is excluded from the scheme, or whether the claim is current.
The same applies to descriptions such as “Siru Mobile slots not on GamStop”. Siru Mobile is a payment method, not a catalogue of games and not a marker of a casino’s self-exclusion status. A casino can change its cashier without changing its regulatory position, and a payment-method description can remain online after the cashier has changed.
Before depositing, identify the exact operating company behind the site rather than relying on a brand name or a page heading. Check that company on the UK Gambling Commission’s public register and confirm that the licence covers the remote gambling service offered to customers in Great Britain. Commercial online gambling offered to Great Britain requires the relevant Gambling Commission licence, regardless of where the operator’s equipment is located. You should also verify the licence number before sending money.
Treat a claim that a site is “not on GamStop” as a separate claim requiring separate evidence. Acceptance of Siru Mobile does not prove it. Nor does the presence of a mobile-payment logo establish that an operator is outside the UK self-exclusion system. Do not label any Siru-accepting casino as non-GamStop merely because it offers that payment route.
If the site has no current UK Gambling Commission licence, it is outside the UKGC regulatory system. That is materially different from a licensed British operator described as not connected to GamStop. The licence check therefore comes first: it establishes the operator’s regulatory position, while the GamStop statement must be assessed independently from the payment method.
A cashier showing Siru Mobile may therefore answer one narrow question—whether that route is displayed for deposits. It cannot, by itself, answer whether the casino is suitable for someone seeking a non-GamStop site.

Pay-by-Phone Deposits and Welcome-Bonus Terms
A Pay by Phone deposit does not automatically qualify for a casino’s welcome offer. The deciding factor is the operator’s bonus policy, not simply the payment brand shown in the cashier. This matters when you are considering Siru Mobile casinos for real-money play: a Siru Mobile deposit may be accepted for funding while still being excluded from the promotion that you intended to claim.
A specialist review identifies MrQ, Duelz, Mr Vegas and Videoslots as operators where Pay by Phone deposits are accepted for bonus eligibility. That is an operator-specific finding, not a rule that applies to every casino accepting Siru Mobile or another mobile-billing service. The payment option and the promotional terms must therefore be checked together before you deposit.
The welcome offer itself may include several separate conditions. A typical UK casino promotion described in a specialist review is a 100% deposit match up to £100, with wagering of 35 times the bonus amount. The same type of review gives a validity period of 30 days for bonus funds and 72 hours for bonus spins. These figures describe a reported promotional pattern, not a fixed requirement imposed on all UK casinos. An operator can use different values, conditions or expiry periods.
UK casinos that accept Boku: what to check
Read the terms for the exact payment method, rather than relying on the headline displayed beside the registration offer. Check whether a Siru Mobile or other Pay by Phone deposit counts as the qualifying deposit, whether the bonus must be activated before payment, and which balance is subject to wagering. Also check the expiry wording: a time limit can apply to bonus funds and a separate one to spins.
A search for a Siru Mobile slots bonus or a no-deposit bonus should not be treated as proof that such an offer exists. Acceptance of mobile-paid deposits establishes how you may fund the account; it does not establish eligibility for a welcome promotion, free spins or a no-deposit reward. Deposit only after the relevant bonus terms state that your chosen Pay by Phone method qualifies.
Can I deposit by phone bill without Boku?
Yes. Some UK casinos offer Fonix or Siru Mobile instead; for example, MrQ and Duelz are associated with Fonix, while Mr Vegas and Videoslots are associated with Siru Mobile. Check the casino cashier to see which options are available to you.
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 £40 or £50. Network-level limits are typically about £10 per transaction and £30 per day, and PAYG deposits cannot exceed your remaining phone credit.
Why are UK casinos dropping Boku?
Some operators have dropped Boku because of compliance risk. There was no UK Gambling Commission rule specifically banning it; casinos may switch to Fonix or Siru Mobile, or remove pay-by-phone deposits.
Are Boku casinos still available in the UK in 2026?
Yes. A small number of UKGC-licensed casinos still accept Boku, including BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino. Check the casino’s cashier, as payment options can change.
How to deposit with Boku at online casinos?
Select Boku in the casino cashier, choose an amount and enter your phone number, then confirm the deposit using the SMS verification code. Boku deposits are available in amounts divisible by ten, such as £10, £20 or £30.
Are there any Boku casinos left in the UK?
Yes. The remaining direct-Boku sites include Jackpot Mobile Casino and Peachy Games, and other reported UKGC-licensed operators include BoyleSports, Sun Bingo, William Hill, Sky Vegas, PlayOJO, Genting Casino, Betfred, Lottoland, bwin and 888 Casino. Verify Boku is still listed in the cashier before depositing.
