Is Siru Mobile still an option at UK casinos?
Yes, but it is no longer a payment option you can assume every UK casino will offer. Pay by Phone has become a moving target: some operators have retained it, some have replaced one provider with another, and others have removed the option altogether.
That matters when you are looking for casinos that accept Siru Mobile in the UK. The name of the payment method is not enough on its own. You still need to open the cashier at the operator you are considering and check whether Siru Mobile appears for your account and mobile network.
The clearest documented examples are Mr Vegas and Videoslots, which have been reported as accepting Siru Mobile deposits. That does not turn them into a permanent list of every Siru Mobile casino in Britain. Payment menus change, and an operator can remove a method without changing its casino brand or website address.
So I would treat those names as examples of reported availability, not as a promise that the option will be present whenever you visit. I have made the mistake of assuming that a payment logo on an old page meant the method was still live. It is a quick way to waste time at the cashier.
Siru Mobile is not Boku
The two services are easy to mix up because both belong to the Pay by Phone category. They are separate payment methods, however. A casino accepting Boku is not automatically a casino accepting Siru Mobile, and a cashier showing Siru Mobile does not prove that Boku is available there.
This distinction is especially important because much of the older UK casino information concerns Boku rather than Siru Mobile. Boku has been used for deposits charged to a mobile phone bill or taken from prepaid credit, but it is a different service from Siru Mobile. Details about Boku should not be copied across to Siru Mobile as though the two systems were interchangeable.

The broader Pay by Phone market has shifted since 2023. A specialist review described operators moving away from Boku towards Fonix or Siru Mobile, while some removed mobile-payment choices completely. That helps explain why older pages can point you towards Boku while a current cashier offers Siru Mobile instead.
The same review identified MrQ and Duelz with Fonix, and Mr Vegas and Videoslots with Siru Mobile. Those are different routes, even though both are phone-based. If you specifically want Siru Mobile, selecting Fonix at the cashier is not a substitute simply because it also uses your phone.
Why availability keeps changing
The decline of Boku was not caused by a UK Gambling Commission rule naming and banning Boku. Individual operators moved away from it because of compliance risk. That is a useful distinction: a payment method can disappear from a casino because the operator changes its risk policy, not because the regulator has prohibited that brand by name.
The same practical uncertainty applies to Siru Mobile. A payment provider may be listed on an information page, mentioned in an older review, or visible at one operator while absent at another. The only useful check is the current cashier, after you have registered and passed the operator’s required checks.

There is also no separate category of “Android Siru Mobile casinos” that changes the basic position. If the operator supports Siru Mobile, the relevant issue is whether the method is offered in its cashier and works with your mobile account. The phone’s operating system does not turn a Boku cashier into a Siru Mobile cashier.
The UK licensing point
For British customers, the operator’s payment options sit inside the wider UK gambling licensing system. The UK Gambling Commission regulates commercial gambling in Great Britain, including remote gambling offered to consumers there. It remains the sole regulator for commercial gambling in Great Britain, and it issues operating licences to gambling businesses as well as personal licences to people working in the industry.
The location of the casino’s key equipment does not remove the licensing requirement when the operator offers remote gambling to consumers in Great Britain. In plain English, a casino selling real-money gambling to British customers needs the relevant Gambling Commission operating licence.
UK Licensing Check
Before depositing, check the operator’s licence number on the UK Gambling Commission’s public register. This check is separate from the payment check and ensures the casino is authorised to serve the British market.
Before depositing, check the operator’s licence number on the UK Gambling Commission’s public register. That check is separate from the payment check. Seeing Siru Mobile in a cashier tells you which deposit route is being offered; it does not replace checking whether the casino is authorised to serve the British market.
Northern Ireland is a separate legal point because the Gambling Act 2005 governs England, Wales and Scotland, but not Northern Ireland. The licensing statement above concerns Great Britain, which is the territory covered by the Gambling Commission’s remote-gambling rules.
What you can reasonably expect in 2026
The short answer is that Siru Mobile remains a possible Pay by Phone route, but availability is limited and subject to change. Mr Vegas and Videoslots are the documented examples linked with Siru Mobile, while MrQ and Duelz are associated with Fonix instead. Boku belongs in a separate column, not as a synonym for every mobile deposit service.
I would check three things before committing: the current cashier, the operator’s UK Gambling Commission licence on the public register, and the payment terms shown at the point of deposit. Do not rely on a “best Siru Mobile casinos” list frozen in an old page. With this payment method, old information goes stale quickly.

When pay-by-mobile is missing, what can you use instead?
If you are looking for casinos that accept Siru Mobile in the UK and the option is not shown at the cashier, the practical answer is not to keep refreshing the same page. Pay-by-phone options have changed, and operators have moved between providers or removed the method altogether. A specialist review describes the post-2023 shift as a move away from Boku towards Fonix, Siru Mobile, or no pay-by-mobile service at all.
That leaves you with two sensible approaches: use another payment method already available at the casino, or look for a different pay-by-phone provider rather than assuming that Siru Mobile will appear under another name.
Fonix is the closest alternative in the pay-by-phone category
Fonix is one of the services that has replaced Boku at some operators. It is not the same product as Siru Mobile, so you should treat it as a separate option in the cashier. A casino offering Fonix does not automatically accept Siru Mobile, and the reverse is also true.
The main UK mobile networks associated with Pay by Phone and Fonix are:
- EE
- O2
- Vodafone
- Three
That network support makes Fonix a realistic alternative to check, but it still does not prove that every operator using one of those networks will offer it. Payment methods are enabled by the individual casino. Your network may support the service while the casino’s cashier does not.
This is where I have made the mistake before: I saw that a payment provider worked with my network and assumed the casino would accept it. The cashier decides. Not the network advert.
Siru Mobile, Fonix and Boku are not interchangeable
The names are easy to blur together because they serve a similar purpose: letting you charge a deposit to your phone service rather than using a card or bank account directly. They remain separate payment routes, however.
A casino may list Siru Mobile, Fonix or Boku as individual buttons. It may list only one of them, or none. A page mentioning “Pay by Phone” also needs checking, because that label may lead to one provider rather than all available providers.
Do
- Check the current cashier for available methods
- Verify the operator’s UKGC licence on the public register
- Look for Fonix as a named alternative if Siru Mobile is absent
Don’t
- Assume a payment logo on an old page means the method is still live
- Use a phone number on an unrelated payment screen
- Treat Boku as a synonym for Siru Mobile
So, if Siru Mobile is absent, look for Fonix as a named alternative. Do not enter a phone number into an unrelated payment screen simply because the general description says mobile payments are supported. The provider shown at the point of payment matters.
Neteller can provide an indirect route
There is also an indirect option involving Neteller. A specialist review reports that players can fund Neteller with Boku and then use Neteller at casinos that accept Neteller.
That route is different from depositing directly with Siru Mobile. It has two stages: the mobile-payment service funds the Neteller account, and Neteller then appears as the payment method at the casino. The casino is not receiving a Siru Mobile deposit in that second step.
This can help when the casino accepts Neteller but does not display Siru Mobile or Fonix. It also means that availability depends on both parts of the chain. Boku must be available for funding Neteller, and the casino must accept Neteller for the later deposit. If either side is missing, the workaround stops there.
I would not describe this as a universal solution. It is a documented route, not a guarantee that every Boku account, Neteller account or casino cashier will present the same choices. Check the available method before moving money.
What to check when the mobile option disappears
Start with the casino’s cashier and identify the exact payment names shown there. If Siru Mobile is absent, check whether Fonix or Neteller is listed. A general statement that the operator supports Pay by Phone is not enough to identify the provider available to you.
Casinos That Accept Zimpler in the UK: Payment Checks
You should also make sure you are dealing with a casino serving the British market under the appropriate UK Gambling Commission licence. The Commission regulates remote gambling offered to consumers in Great Britain, and a UK-facing operator must hold the relevant operating licence. The public register is the place to verify that status before depositing.
Do not use a credit card as a substitute for a missing mobile method. UK-licensed casinos cannot accept credit cards for gambling, including arrangements that route credit-card funds through a money service business. Wallets also cannot be used where they allow credit-card funds to fund gambling.
That leaves the cashier’s permitted methods as the deciding factor. If the casino offers Neteller, the Boku-to-Neteller route may be relevant. If it offers Fonix, that may replace the missing Siru Mobile button. If neither appears, the operator has not provided one of these documented alternatives through that account.
Avoid choosing a casino from a payment list alone
A list of names claiming to be the “best Siru Mobile casinos” can go stale quickly because operators change their cashiers. It also does not tell you whether the payment method is available to your account, network or location at the moment you try it.
I would check three things in order:
- The exact provider displayed in the cashier.
- Whether the operator holds a current UK Gambling Commission licence.
- Whether the payment route you plan to use is permitted for gambling and suits the way you intend to fund the account.
That approach is less exciting than a long recommendation list, but it avoids treating an old Boku reference as proof of current Siru Mobile acceptance. Payment labels change. Verify the button first.
Paying by phone doesn’t change how slots work
Siru Mobile is a way to fund a casino account, not a special type of slot. Once the balance is available, the game itself does not become a “Siru slot”, and the payment route does not alter its reels, features, volatility or rules. I have seen these things blurred together in casino pages, with “mobile slots” made to sound like a separate product. It is mostly a label for how you reached the balance.
That distinction matters if you are looking for online slots with Siru Mobile in the UK. You are not choosing a different machine because you used Pay by Phone. You are choosing a casino that offers both the games you want and the payment method you intend to use. The cashier and the game lobby are separate parts of the site.
Payment vs Games
Siru Mobile is a way to fund an account, not a specific type of slot. The payment route does not change the game’s reels, features, or rules.
A specialist review has listed Mr Vegas and Videoslots as accepting Siru Mobile, while naming MrQ and Duelz for Fonix instead. Treat that as a time-sensitive snapshot rather than a permanent directory. Payment options change, and the presence of a method does not tell you which slots are available. It also does not, by itself, establish anything about the operator’s current licence position.
The British rules apply to the game
For real-money online slots supplied to customers in Great Britain, the operator must be licensed by the UK Gambling Commission. The Commission regulates remote gambling offered to people in Great Britain, even when the operator’s key equipment is located elsewhere. That is why the payment brand is not the main legal question. The important point is whether the casino serving you holds the appropriate current UKGC operating licence.
I check the licence on the Commission’s public register before putting money into an account. It is a dull step, but it is more useful than a page calling itself a “trusted slots site” and surrounding the claim with bright buttons. An offshore casino may still be accessible, but it is outside the UKGC system and is not the same thing as a UK-licensed operator.
Casinos That Accept Ethereum in the UK: What to Check
Age checks also come before gambling. Operators must verify a customer’s age before allowing deposits into a gambling account, and online gambling is legal for players aged 18 and over when the operator holds a UKGC licence. A phone payment does not bypass those checks. It is not a shortcut around account verification.
Stake limits depend on your age
The maximum stake per online-slot game cycle is £5 for customers aged 25 and over. For customers aged 18 to 24, the maximum is £2. The £5 limit for all adults came into force on 9 April 2025.
That applies to the slot play, not to the amount you happen to add through Siru Mobile. A mobile deposit does not create an allowance above the permitted stake, and a larger account balance does not change the age-based rule. If the casino blocks a stake above the relevant maximum, that is part of the British online-slot framework rather than a fault with the payment service.
I made the mistake once of treating the amount in the cashier as if it told me what I could stake. It does not. Different questions.
Essential Checks
- Verify the exact provider in the cashier
- Confirm the operator holds a valid UKGC licence
- Check if the payment route is permitted for gambling
Spin speed and autoplay
British online slots must keep each spin running for at least 2.5 seconds. That rule concerns the game cycle, so it remains the same whether the balance came from Siru Mobile, another payment method or funds already sitting in the account.
Autoplay is banned for online slots in Britain. You must start each spin yourself rather than setting the game to continue automatically. Again, this has nothing to do with the phone network or the payment screen. A casino cannot turn autoplay into an extra feature simply because you are playing on a mobile device.
That also explains why “Siru Mobile slots app” can be a misleading phrase. You may play through a casino’s mobile website or app, but the app is the access point, Siru Mobile is the payment route, and the slot remains a regulated online game. Those are three separate things.
Free-play versions can be useful for learning the controls, but they do not turn a payment method into a game category. When real money is involved, the UK rules on age, licensing, stake size, spin duration and autoplay still define the conditions. Check the operator and the game screen itself, not just the payment logo.
What happens when you make a pay-by-phone deposit?
When I tested the Boku route, it felt less like using a card and more like authorising a charge through the phone number attached to the account. That distinction matters if you are looking for a Siru Mobile casino: the cashier has to display the payment service you want to use. Seeing “Pay by Phone” in general does not mean that Boku, Siru Mobile, or another provider is available there.
Casinos That Accept Giropay in the UK: What to Check
The process starts in the casino cashier. After signing in, you open the deposit area and select Boku from the listed payment methods. You then enter the amount you want to add and provide the mobile number that Boku will bill. It is not a case of typing any number and hoping for the best; the phone must be connected to the payment arrangement being used.
A verification message follows. Boku sends an SMS containing a confirmation code, which you enter where the cashier asks for it. That code is the approval step for the transaction. Until it is entered correctly, the deposit has not been authorised. I would check the number on the screen before confirming, because correcting a mistyped mobile number after the message goes elsewhere is not a clever way to spend an evening.
Once confirmed, the charge is handled through the mobile network rather than a debit card. With a contract phone, the Boku payment is placed on the monthly mobile bill. With a pay-as-you-go phone, the amount is taken from the available PAYG credit. So the casino cashier may show a successful deposit attempt while the network still has to approve the charge against the billing arrangement or remaining prepaid balance.
The amount selector may also look different from a card cashier. A specialist review describes Boku deposits as being offered in tens: the examples given are £10, £20 and £30. In other words, that account of the service does not describe a free-entry amount field where every pound is available. The exact choices are still something I would read from the cashier itself, especially because pay-by-phone arrangements change as operators replace or remove payment options.
Boku Deposit Process
Step 1: Selection
Open the deposit area in the casino cashier and select Boku from the listed payment methods.
Step 2: Details
Enter the amount you wish to add and provide the mobile number that Boku will bill.
Step 3: Verification
Enter the confirmation code sent via SMS to authorise the transaction.
This is why searches for online casinos accepting Siru Mobile deposits can lead to a slightly confusing result. “Pay by Phone” is a broad label, while the actual provider appears only after you open the cashier. If the screen lists Boku, the flow is: select Boku, enter a permitted deposit amount, add your mobile number, then enter the SMS code. The resulting charge reaches either your phone bill or your PAYG balance.
No card details are entered into that Boku form. The phone number and the SMS confirmation do the work. Keep it simple.
Deposits are easy; getting your money back is different
Paying into a casino account and taking money out are two separate jobs. I learned that the annoying way: a payment button can be perfectly suitable for funding play while being completely useless when you want to cash out.
Boku is the clear example. It can be used to put money into an online casino account, but it is deposit-only. Casino winnings cannot be sent back to your Boku account, and the payment will not appear as a route for withdrawing funds. In other words, using Boku for real-money slots does not create a matching “send it back to my phone bill” option.
That matters when you are looking at casinos that mention Pay by Phone, Siru Mobile or another mobile-payment label. Do not treat the presence of a mobile deposit method as proof that the same method handles withdrawals. The cashier may accept your phone payment at the deposit stage and then ask you to register a completely different way to receive money.
Casinos That Accept Maestro in the UK
I now check the withdrawal page before making a deposit. It is a less exciting place to look, but it prevents a predictable mistake. You should have an alternative withdrawal method registered with the casino, such as a debit card, e-wallet or bank transfer. The available choices depend on the operator, so read what is shown in your account rather than assuming that every casino supports every route.
There is also a practical difference in how the two actions feel. A Boku deposit is designed to charge the mobile account or phone bill and credit the casino balance. A withdrawal reverses the direction of the money, and Boku does not provide that service. Your winnings therefore remain in the casino account until you request payment through an accepted alternative.
This is easy to overlook when you are searching for online slots that accept Siru Mobile or another Pay by Phone option. The payment method can make the initial deposit seem straightforward, but it says little about the final step. “Mobile money in and out” sounds tidy; in practice, it is only money in.
Before playing for real money, open the cashier and identify the withdrawal route you would use. If there is no suitable option, the convenience of the deposit is beside the point. I would rather discover that before funding an account than after a winning session.
A simple rule works here: check the exit before entering. Pay by phone may get funds into the balance, but Boku cannot bring casino winnings back out.
Small limits, set partly by your mobile network
Pay by Phone deposits are not controlled entirely by the casino cashier. With Boku, the mobile network can apply its own ceiling, so a payment may be refused even when the casino account is ready to accept it. That is an easy detail to miss when comparing casinos that accept Siru Mobile or other phone-payment services.
Network Limits
Attention The mobile network may apply its own transaction ceilings, which can cause a payment to be refused even if the casino accepts it.
The published figures are not consistent. A specialist review gives £30 per Boku transaction as the standard UK limit, while saying that some casinos and network operators may permit £40 or £50. Those higher figures should be treated as operator-specific possibilities, not as a market-wide entitlement.
Another account describes Boku as limited to about £10 per transaction and £30 per day at network level. However, the same subject is reported differently elsewhere: the daily limit is given as £30, with no per-transaction ceiling specified. That is a direct disagreement, not a distinction you can safely smooth over. The amount available to you may depend on the mobile operator, the casino and the version of the payment service presented at the time.
The daily cap is particularly important because a casino does not necessarily decide whether you have reached it. A specialist review attributes enforcement of the daily Boku limit to the mobile operator rather than the casino. In practical terms, several deposits can be blocked after the network’s allowance has been used, even if the casino itself has not imposed a matching restriction.
This also explains why two players can see different results when trying to fund similar casino accounts. The payment button may appear in both cashiers, but the network’s rules can still determine whether the transaction goes through. A declined payment therefore does not automatically mean that the casino has removed Pay by Phone; it may indicate that the mobile account has reached its permitted limit.
Casinos That Accept Monzo in the UK: What to Check
Boku should not be confused with Siru Mobile. A search for casinos accepting Siru Mobile may lead to information about Boku because both sit in the broader Pay by Phone category, but their availability and limits are not interchangeable. Check which service is actually displayed before relying on a stated cap.
The safe reading is simple: £30 per transaction is one reported Boku benchmark, while £30 per day is another reported network-level figure; £10 per transaction also appears in conflicting coverage. The mobile operator may have the final say. Small numbers, real barrier.
Alternatives if you want to pay by phone
I used to think Boku was simply the Pay by Phone option at UK casinos. That was an easy assumption to make when the cashier showed one familiar name. The market has become less tidy since then. Operators have been moving away from Boku, with some introducing Fonix or Siru Mobile and others removing Pay by Phone altogether.
A specialist review describes this change as having gathered pace since 2023. I would treat that as a snapshot, not a permanent map of the market. Payment menus change, and a service that appeared at registration may disappear before you return to make a deposit.
The main services you may see
Boku, Siru Mobile and Fonix are separate payment services. They all sit in the same broad Pay by Phone category, but seeing one available does not mean the others will also be offered. That distinction matters when you are looking for a Siru Mobile replacement: the useful alternative may be Fonix, or there may be no phone-billing option at that operator.
Pay by Phone and Fonix are supported by the UK’s major mobile networks:
- EE
- O2
- Vodafone
- Three
That network support makes Fonix a notable alternative in the current payment landscape. It does not, however, confirm that every casino using one of those networks will display Fonix in its cashier. The operator still decides which payment services to provide.
Siru Mobile belongs in the same changing picture. Some operators have moved towards it as Boku availability has reduced, while others have dropped Pay by Phone completely. So, when I check whether Siru Mobile is still active, I do not assume that a historical payment guide is current. I look for the method in the actual cashier and check the operator’s UK Gambling Commission licence before depositing.
That is less exciting than a list of “best” phone-payment casinos, but it is more honest. A payment brand can be supported nationally and still be absent from the casino you use. The network is only one part of the chain.
Check the cashier first. Pay by Phone availability is operator-specific, and the landscape is still moving.

Check the amount before you try to deposit
If you use Pay by Phone with a PAYG mobile, the first limit is sitting on the phone itself. The Boku charge comes from your remaining prepaid balance, so a deposit cannot exceed the credit available at the time. A casino cashier may show a payment option, but that does not mean your balance can cover every amount offered.
That point matters when looking for a small deposit at a casino accepting Siru Mobile or another Pay by Phone service. Boku and Siru Mobile are different services, and a limit described for Boku should not automatically be treated as a Siru Mobile limit. Check which payment brand appears in the cashier before relying on any figure.
The published Boku figures do not line up
There is a direct disagreement between the figures reported for Boku:
- One set gives a minimum deposit of €10, a maximum of €30, and a monthly ceiling of €240.
- Another account describes the UK standard as £30 per transaction, with some operators or mobile networks allowing £40 or £50.
Those are not interchangeable limits, and the currency difference makes the first set especially unsuitable as a simple UK rule. The safer reading is that Boku limits can depend on the particular operator, network and information being used. A specialist review reported the PAYG-balance restriction, while the separate limit figures conflict, so check the cashier rather than assuming the larger amount will be accepted.
A deposit can therefore fail for two different reasons: the requested amount may be outside the Boku limit shown for that casino, or your prepaid balance may be too low to pay it. The latter is straightforward: Boku cannot draw more than the credit left on the phone.
For a casino that advertises instant deposits through Siru Mobile, look at the actual payment screen and its displayed minimum before entering funds. Do not treat a Boku maximum, a Siru Mobile label or a search result as proof that the same amount applies everywhere.
And if the cashier offers a figure that differs from the advertised terms, use the cashier’s current information as the practical checkpoint. Small detail, but it saves a failed payment.
Can I withdraw money to my phone bill?
No. Methods like Boku are deposit-only. You must use an alternative method, such as a debit card or e-wallet, to receive winnings.
Are Boku and Siru Mobile the same?
No. They are separate payment services within the Pay by Phone category and are not interchangeable.
A Siru Mobile payment does not tell you a casino’s GamStop status
Seeing Siru Mobile in a casino’s cashier tells you one thing only: that the operator may support that payment route. It does not tell you whether the site is connected to GamStop, accepts self-excluded customers, or sits outside the scheme. Payment acceptance and self-exclusion status are separate checks.
I made that assumption myself once. A familiar payment logo made a site look more established than it really was. That was the wrong shortcut. A payment provider is not a badge showing how a casino handles self-exclusion.
If you are looking for casinos that accept Siru Mobile but are not connected to GamStop, be careful with lists making that promise. The position of an operator can change, and a payment option alone cannot prove it. The same applies to claims about Siru Mobile slots that are “not on GamStop”: the slot does not carry the casino’s self-exclusion status. The operator and its account controls are what matter.
For a UK-facing casino, check the operator’s current UK Gambling Commission licence on the public register before depositing. Remote gambling offered to consumers in Great Britain requires the relevant licence, regardless of where the operator or its equipment is based. A licensed casino must also provide responsible-gambling tools, including self-exclusion, and must have an internal complaints process with access to an approved Alternative Dispute Resolution service.
That licence check still does not turn Siru Mobile into proof of GamStop participation. Treat the two questions separately:
- Does the casino currently accept Siru Mobile?
- What is the casino’s current self-exclusion and GamStop position?
Do not infer the second answer from the first. I would check the operator’s own current information and the relevant self-exclusion service before opening or funding an account. If you have already registered with GamStop, trying to work around that protection is a different matter from choosing a payment method. The sensible move is to respect the exclusion rather than hunt for a route around it.
The logo is not the answer. It is just a logo.
Check the bonus terms before paying by phone
A Siru Mobile deposit does not automatically qualify for a welcome offer. Each operator decides which payment methods count, and pay-by-phone funding may be left out even when the casino advertises a bonus to new customers. I have made that assumption before: seeing the promotion was not the same as having a qualifying deposit.
A specialist review confirmed bonus eligibility for pay-by-phone deposits at MrQ, Duelz, Mr Vegas and Videoslots. Treat that as operator-specific information rather than a permanent rule for every Siru Mobile casino. Payment options and promotional terms can change, so the wording in the cashier and the bonus page matters more than an old description elsewhere.
Casinos That Accept Litecoin in the UK: What to Check
The offer itself may also carry conditions that are easy to skim past. A typical UK welcome promotion described in specialist bonus coverage matches a player’s deposit at 100%, with the matched amount capped at £100 and winnings subject to a 35x wagering requirement. In plain English, the bonus is not withdrawable simply because it has appeared in your balance. The wagering condition has to be met under the operator’s rules.
Time limits can matter just as much. Bonus funds in the same type of offer expire after 30 days, while bonus spins expire after 72 hours. Those are separate clocks, so receiving spins does not give you the same period as the matched funds. Miss the relevant deadline and the unused promotional value can disappear.
For a Siru Mobile welcome bonus, check four points before depositing:
- whether Siru Mobile or another pay-by-phone method is an eligible funding route;
- whether the offer is a deposit match, free spins, or both;
- the wagering requirement attached to bonus funds;
- the expiry period for the funds and any spins.
Do not read “no deposit bonus” as proof that a phone-funded account qualifies either. The operator’s terms decide whether registration alone is enough, or whether a particular deposit method is excluded. A quick check can prevent a small phone payment from becoming an ineligible one.
What are the deposit limits at pay by mobile casinos?
For Boku, the usual UK limit is £30 per transaction, although some casinos or 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 moved away from Boku because of compliance risk, replacing it with another mobile payment provider or removing pay-by-mobile options. The UK Gambling Commission did not introduce a rule banning Boku by name.
How does Boku work?
Choose Boku in the casino cashier, enter your deposit amount and mobile number, then confirm the payment with the SMS verification code. The charge is added to your phone bill or deducted from your PAYG credit.
