What are Pay By Phone Casinos?
Pay by phone casino sites let players deposit using their mobile phone bill or prepaid balance rather than a bank card or e-wallet.
As long as you hold a UK SIM card, you can use the method at any casino that supports it.
How the charge works depends on your contract type.
If you're on a monthly contract, deposits are added to your bill and settled at the end of the month. If you're Pay As You Go, the amount is taken directly from your prepaid balance.
The market has changed significantly since 2023, with Fonix now the primary provider at UKGC-licensed casinos.
It processes deposits under the Pay By Mobile brand. Boku, which was previously the most recognised name in this space, has been withdrawing from UK casino operators and the number of sites accepting it is falling.
Payforit is no longer active in the casino market. Siru Mobile remains available at a small number of operators, including Videoslots and Mr Vegas, though it carries fees of 25% to 33%.
For most players in 2026, Pay By Mobile powered by Fonix is the standard.
My View
Pay By Mobile (Fonix)
Fonix is the leading pay by phone provider at UK casino sites in 2026. Operating under the Pay By Mobile brand, it allows you to deposit using your mobile phone bill or prepaid balance.
The PSA-mandated daily limit is £40, with a monthly cap of £240. Deposits are confirmed via a four-digit SMS PIN and no financial information is shared with the casino. Compatible with all major UK networks.
Siru Mobile
Siru Mobile is used at Videoslots and Mr Vegas.
It works differently from Fonix - deposits are billed directly to your phone but carry fees of between 25% and 33%, meaning a £4 deposit becomes £5.12 after charges.
You should always confirm the fee before depositing. The maximum deposit is around £18.90 before fees.
Boku
Boku was previously the most widely used pay by phone method at UK casino sites but has been withdrawing from UKGC-licensed operators since 2023.
It's still accepted at a small number of sites but the list is shrinking. If you intend to use Boku, verify it is available at your chosen casino before registering. Where available, the daily limit aligns with the PSA cap of £40.
Payforit
Payforit is no longer active in the UK casino market.

No Withdrawals Using Pay By Phone
The downside to playing at Pay By Phone casinos is that you cannot withdraw your funds back to your mobile phone account.
If you manage to win big, your next problem will arise.
It will require you to possibly contact an online casino’s customer service department to discuss the options you have.
Inevitably, it means you will need to choose a casino payment method to receive your winnings.
There are plenty of options, including e-wallets (like PayPal) and debit cards. Below are a few options you have:
- PayPal: PayPal is arguably the most popular way to deposit and withdraw funds at gambling sites. Quick and pain-free, there are over 436 million PayPal users worldwide (as of May 2024) and is popular with online retailers such as eBay. Widely accepted in the UK including ASOS, Nike, Boots and River Island, PayPal offers a high level of security, is available for all casino bonuses and ensures fast withdrawals.
- Debit Cards: Linked directly to your bank account, VISA and Mastercard debit cards are used by most people around the world. Accepted everywhere, you will need to enter your card number, expiry date and security code information when you deposit though. Deposits and instant but withdrawals can take up to 3 working days due to banks’ processing times.
- Apple Pay: Also available to use on mobile devices, Apple Pay has become very popular in recent years. Easily linked to your debit card, Apple Pay is widely accepted online and is eligible for casino bonus offers. Withdrawals are also free and fast.
- Google Pay: Similarly to Apple Pay, Google Pay is for Android users only. Increasingly more popular, you can link your debit card instantly as well as deposit and withdraw at a whole host of casino sites with ease. It’s also valid for welcome bonuses and has no fees associated.
- Trustly: Most gambling sites now accept Trustly deposits and withdrawals. Available to use on mobile and tablet devices, Trustly connects to your bank account and offers fast, secure and free transactions.
Deposit Limit Restrictions
- £40 per day
- £240 per calendar month
When depositing at Pay by Phone Bill casinos in the UK, there are deposit limit restrictions you need to consider. The maximum you can deposit per day is £40 whilst the most you can deposit across a calendar month is £240.
With many casino bonuses offering match offers up to £100, you will not be able to claim to full bonus on offer if you use a Pay By Mobile method. Other options available such as PayPal and Apple Pay are better suited if you want to take advantage fully of a bigger casino offer.
Whilst the deposit amounts are added to your monthly mobile bill, Pay As You Go phone users will need to top up their account if they play regularly. For Pay As You Go users, it’s a good way to ensure you gamble responsibly and don’t overspend. If you’re on a contract, you may suddenly find yourself with a much bigger mobile bill the following month.
Pay By Phone Casinos Pros & Cons
With no withdrawals using Pay By Phone payment methods, this leads us nicely to the advantages and disadvantages of using this mobile payment option.
Whilst there are lots of reasons to deposit at Pay By Phone bill casino sites, there are also downsides you need to consider:
Pros
- No financial information shared with casino
- Easy and quick to use
- Instant deposits
- Secure and safe (SMS verification on every transaction)
- Increasing number of casino sites offering Pay By Mobile options
- Compatible with iOS and Android smartphones

How to Choose the Best Pay by Phone Casinos
If you’re happy using Pay By Mobile deposit methods, you also need to ensure the casino site is up to standards on other fronts.
Below is a list of things to consider before deciding to play at a Pay by Phone casino:
- 🛡️ Licensed by the UK Gambling Commission: All UK sites must be regulated and licensed by the Gambling Commission. This ensures fairness, that your information is secure, processes and standards are in place and responsible gambling tools are readily available. If you’re in Europe, look out for those licensed by the Malta Gaming Authority.
- 💳 Wide Range of Payment Methods: Pay by Phone withdrawals are not possible so you need to be able to take out your winnings if you get lucky. Popular payment options like PayPal, debit cards, Apple Pay, Neteller and Skrill are the most common choices. Check how quickly they process withdrawals and if there are restrictions such as fees. Weekend cashouts are also a big plus.
- 📱 Easy-to-use Site + Mobile Compatibility: Being able to navigate the casino site effortlessly is a must these days. This includes finding your favourite casino games, a clear My Account section, the ability to deposit and withdraw with ease and access to information is key to enjoying your experience. The site needs to be mobile and tablet-friendly with dedicated iOS and Android apps ideal.
- 🎰 Lots of Casino & Slot Games: The Pay by Phone casino needs to have a good selection of casino games including blackjack, roulette and live dealer options. Look for a wide range of slot games from reputable studios such as Pragmatic Play, NetEnt, Nolimit City and Play ‘n GO (amongst others).
- 🎁 Promotions & Offers: Having a welcome offer is ideal but there needs to be ongoing promotions and offers for existing customers. Make sure the offers have clear and transparent terms and conditions including details on eligible games, wagering requirements and restrictions. The best Pay by Phone casinos will offer weekly offers as well as cashback and slot tournaments.
- 📞 Support & FAQs: Round-the-clock customer support via Live Chat is ideal but a comprehensive Help of FAQs section will suffice most of the time. Having support on hand is the goal with a UK telephone number and quick response times what you need to ensure any issues that may arise are dealt with promptly and efficiently.

Summary
Pay by Phone casinos are on the rise in the UK with more and more of us using our smartphones to play our favourite casino and slot games.
Charging your deposit to your mobile phone bill or deducting from the Pay As You Go balance is very straightforward, quick and easy.
However, you can only deposit up to £40 a day and £240 per month.
The other major drawback is that you cannot withdraw using this method so another popular payment option is needed (look into the section above for other options).
