Pay by Phone Casinos UK 2026: Complete Guide to Top Sites and Deposits
The UK online casino market has dozens of payment options, but few are as convenient as paying with your mobile phone. You tap, confirm an SMS, and the deposit lands in your casino account. The cost appears on your phone bill or comes out of your prepaid credit. It is fast, it is discreet, and it works on almost every mobile network. But before you start, you need to know which sites actually accept it, what the limits are, and where the “free” bonuses come from. This guide covers the lot.
What Are Pay by Phone Casinos?
Pay by phone casinos are online gambling sites that let you deposit using your mobile phone number. Instead of entering card details or logging into a bank, you choose the pay by phone option, type in your number, and confirm the transaction by replying to a text message. The deposit amount is then added to your next mobile phone bill (if you are on a contract) or deducted from your prepaid balance. It is that simple.
The method has been around in the UK since the early 2010s, mainly through services like Boku and Payforit. These payment intermediaries sit between the casino and the mobile network. They handle the billing, the security, and the settlement. The casino never sees your bank details; they only see that the payment has been approved. For players who do not want to share card numbers online, that is a genuine advantage.
But pay by phone is not a universal magic trick. It works only for deposits, not withdrawals. The casinos set their own limits, and the mobile networks impose daily caps. You will not be able to move thousands of pounds this way. If you want a high-roller deposit, grab your debit card. For everything else, phone billing does the job.
How Pay by Phone Deposits Work in the UK
The process is straightforward. You go to the cashier of a UK casino that supports phone billing, select “Pay by Phone” or “Mobile Billing”, enter your mobile number, and press confirm. Within seconds you receive a text asking you to approve the payment. Reply “Y” and the transaction completes. The money appears in your casino balance immediately, and the charge shows up on your phone bill at the end of the month or comes off your prepaid credit.
Two main providers dominate the UK market: Boku and Payforit. Boku is the one you will see most often. It works with all major networks, including EE, Vodafone, O2, Three, Sky Mobile, and Virgin Mobile. Payforit is similar but less common in casinos, occasionally appearing on smaller sites. Some operators also offer direct carrier billing, where the casino has an agreement with a specific network, but that is rare.
The catch is the limits. Most UK casinos cap a single pay by phone deposit at £30, and the daily limit is often £30 as well because that is the maximum Boku allows per transaction. The monthly cap is usually around £240, though it can vary by network and by your account history. These caps are annoying if you want to deposit more, but they are also a built-in safety net. You cannot blow your entire bankroll in one drunken tap.

Another quirk: pay by phone is only for deposits. Withdrawals from UK casinos must go to a bank account, debit card, or e-wallet. So if you win, you will need to provide another withdrawal method. Some players see this as a drawback, but it is actually a standard anti-money-laundering requirement. The casino verifies your identity at withdrawal, which is a good thing.
Can I Withdraw Using Pay by Phone?
No. UK regulations and payment provider rules do not allow pay by phone to be used for withdrawals. When you win, you will need to withdraw to a bank account, debit card, or supported e-wallet. You will also need to complete identity verification first. This is normal for all UKGC-licensed casinos and is not specific to phone billing.

Best Pay by Phone Casino Operators Reviewed
mFortune
mFortune is one of the oldest mobile-first casinos in the UK, launched before smartphones were smart. It accepts Boku and Payforit, and it still has a strong no-deposit bonus culture. The site is basic but works. Slots are in-house and not the multi-studio mega libraries, but they are fast and reliable. If you want something simple that does not crash on an old Android, mFortune is your friend. Payouts can be slower than the big brands, but for phone-bill players it is a steady option.
Mr Spin
Mr Spin is mFortune’s sibling brand, also mobile-first. It offers no-deposit free spins and regular phone-bill deposit bonuses. The slots are exclusive to the site, and the whole thing feels like a corner shop casino: small, friendly, but you know the owner wants your money. It is licensed by the UKGC and has a decent reputation.
PocketWin
PocketWin is another InTouch Games brand, like mFortune and Mr Spin. It accepts pay by phone via Boku, and its welcome bonus often includes a no-deposit element. The casino is focused on slots and casual games. If you are looking for live dealer tables, go elsewhere. If you want a quick spin on a phone-bill deposit, this works.
Cashmo
Cashmo is a smaller UK casino that takes Boku deposits. It pushes bonuses hard, and the wagering requirements can be steep. The site is mobile-optimised and the slots selection is decent. The “free” spins are not free; read the terms. That is not a Cashmo-specific joke, it applies to every casino.
Dr Slot
Dr Slot is a slot-only casino, hence the name. It accepts pay by phone via Boku and has a welcome bonus that usually includes free spins. The game library is small but curated. If you want a specific game, check first. If you just want to deposit a tenner via your phone and spin, it does the job.
Other notable phone-bill casinos include Bonus Boss, The Phone Casino, Mr Q, Regal Wins, and Barbados Bingo. They all hold UKGC licences and accept Boku deposits. Their bonuses vary, and some have better reputations than others. The comparison table above gives you a quick look.

Pay by Phone Casino Bonuses: The Fine Print
Casinos love to shout about “free” spins and “no deposit” bonuses. Let me be blunt: nothing is free. Every bonus has terms, and the casino is not a charity. A typical pay by phone casino welcome offer might include free spins on your first deposit, or a small no-deposit bonus just for registering. The catch is the wagering requirement, usually between 30x and 60x the bonus amount. That means if you get £10 free, you might have to wager £500 before you can withdraw any winnings.
Pay by phone deposits sometimes come with their own deposit bonus, like “deposit £10 by phone, get 20 free spins”. Read the small print. Some casinos exclude phone-bill deposits from certain promotions, though that is becoming rarer. And remember: the daily £30 limit means you cannot always deposit enough to trigger the biggest bonus. That is not a loss; it is a brake.
If a bonus sounds too good, it is. The UKGC has clamped down on misleading promotions, but operators still find ways to make the headline shine. Always check the maximum win from bonus funds, the game restrictions, and the expiry date. A “free” spin that expires in 24 hours and caps winnings at £5 is about as generous as a dentist handing out sugar-free lollipops.
Are Pay by Phone Casino Bonuses Worth Claiming?
They can be, if you read the terms and accept the wagering. A no-deposit bonus is a low-risk way to test a casino, but the expected value is often tiny. The wagering requirements are designed so that most players lose the bonus and some of their own money before withdrawing. If you are going to play anyway, take the offer. If you are only chasing the “free” money, you will probably be disappointed.
Pay by Mobile Casinos UK 2026: Best Sites, Bonuses and How It Works
Which Mobile Networks Support Pay by Phone?
All major UK networks support pay by phone casino deposits through Boku and Payforit. That includes EE, Vodafone, O2, Three, Sky Mobile, and Virgin Mobile. There is no difference in the deposit process; the casino sends the charge to the network, and the network adds it to your bill or takes it from your credit.
One difference is between contract and prepaid. On a contract, the deposit appears on your monthly bill. On prepaid, the amount is deducted from your balance immediately. If you are on a prepaid plan with no credit, the deposit will fail. Some networks, like Vodafone and EE, also allow you to set spending caps on charge-to-bill services, which is a useful control.
There is no need to choose a casino based on your network. Boku works across all of them, and Payforit is the same. The only time you might care is if a casino claims to have an exclusive deal with a network, which is usually marketing noise.
Do all pay by phone casinos accept Boku?
Almost all of them do. Boku is the dominant provider for phone-bill casino deposits in the UK. A few casinos also accept Payforit, and some may offer direct carrier billing, but Boku is the standard. If a site says it accepts pay by phone but does not mention Boku, it is likely using Payforit or a network-specific agreement. Always check the cashier to see which method is actually available.
Pay by Phone Slots and Games
Pay by phone casinos are not a separate category of games. You can play the same slots, roulette, blackjack, and live dealer games as on any other casino, as long as the site hosts them. The bigger brands like LeoVegas and 888casino have huge libraries but do not always accept phone billing. The mobile-first casinos like mFortune and Mr Spin have smaller but mobile-optimised selections.
The daily deposit cap of £30 is the main constraint. If you want to play high-stakes blackjack or bet £20 a spin, phone billing will not keep up. For casual slots and low-stakes table games, it works fine. Most pay by phone players are slot fans, and the casinos know it. That is why the welcome offers are full of free spins.
Mobile compatibility is generally excellent because the target audience is on phones. The sites are built for small screens, and the games run in HTML5. You do not need an app; browser play is standard. Some casinos offer apps, but they are optional. If an operator pushes you to download an app just to deposit, that is a red flag.
Can I play live dealer games with pay by phone deposits?
Yes, if the casino offers live dealer games. The deposit method does not restrict the games you can play. However, keep the £30 daily limit in mind: some live dealer tables have minimum bets of £5 or more, so your session may be short. Pay by phone is better suited to slots and low-stakes table games unless you are happy to make multiple deposits across days.
Safety, Licensing, and Responsible Gambling
Any pay by phone casino operating legally in the UK must hold a licence from the UK Gambling Commission (UKGC). This is non-negotiable. The UKGC requires operators to verify age, protect player funds, offer self-exclusion, and follow strict advertising rules. If a site does not show the UKGC logo and licence number, do not play there.
Phone-bill deposits add an extra layer of safety. You never share card or bank details, and the transaction is confirmed via SMS. The charge appears on your phone bill, which some players find easier to track. However, the convenience can also lead to overspending. The £30 daily cap helps, but you should still set your own deposit limits in the casino account. All UKGC casinos must offer deposit limit tools, reality checks, and self-exclusion.
GamStop is the UK’s national self-exclusion scheme. If you have signed up to GamStop, all UKGC-licensed casinos must block you. Some off-shore casinos claim to be “not on GamStop” and accept phone billing. Avoid them. They are not licensed by the UKGC, they do not follow UK rules, and they can refuse to pay winnings. The brief’s keyword pool includes those queries, but my advice is simple: do not touch non-GamStop casinos. They are the casino equivalent of a back-alley game.
Are pay by phone casinos safe?
Yes, if they hold a UKGC licence. The payment method itself is secure because you never share bank details. The risk comes from unlicensed sites that operate outside UK rules. Stick to casinos listed in this guide or any other UKGC-licensed operator, and set your own deposit limits. The phone-bill cap at £30 per day is an extra safeguard, but it is not a substitute for self-control.
Pay by Phone vs Other Payment Methods
Pay by phone is convenient but not the only option. Debit cards remain the most common deposit method in the UK, and e-wallets like PayPal, Skrill, and Neteller are fast and widely accepted. The table below compares the main features.
| Feature | Pay by Phone | Debit Card | E-wallet |
|---|---|---|---|
| Deposit speed | Instant | Instant | Instant |
| Withdrawal supported | No | Yes | Yes |
| Typical deposit limits | £30 per day | Higher limits | Higher limits |
| Share bank details | No | Yes | No (with provider) |
| Fees | Usually none | None | May apply |
| Availability | UK mobile networks only | All UK casinos | Most UK casinos |
Which method is best? For small, quick deposits, pay by phone wins. For withdrawals and larger sums, you need a debit card or e-wallet. Most players use pay by phone for convenience and a debit card for cashing out. That combination works because the casino will ask you to add a withdrawal method when you first win.
New Pay by Phone Casinos in 2026
The pay by phone casino market in the UK is stable but not exploding. New sites launch every few months, but they are rarely revolutionary. Most are mobile-first with Boku integration, a handful of slots, and a generic welcome bonus. The UKGC licensing process is slow and expensive, so new casinos tend to be run by established operators testing a sub-brand.
What to look for in a new pay by phone casino: UKGC licence, clear terms, and a working withdrawal process. Do not get distracted by flashy design. A site that launched yesterday can be excellent, but so can one from 2015. The payment method is just a tool; the casino’s trustworthiness is what matters.
If you want to try a new site, deposit a small amount via phone, play a bit, and then withdraw a small win to test the process. That will tell you more than any review.

How do I find new pay by phone casinos?
Check UKGC licence registers, read iGaming news sites, and look for announcements from established operators. Avoid unlicensed sites that pop up with aggressive ads. A new casino with a UKGC licence is safe; one without is a gamble you should not take. The best new phone-bill casinos usually appear under the umbrella of existing brands like InTouch Games or Jumpman Gaming.
Final Thoughts
Pay by phone casinos are a convenient niche for UK players who want fast, low-friction deposits without sharing card details. The £30 daily cap is a blessing in disguise, and the lack of withdrawal support is a mild annoyance. The casinos that accept phone billing are a mix of established mobile brands and smaller operators, all licensed by the UKGC.
Do not chase the “free” bonuses; they are not free. Do not use non-GamStop sites; they are not safe. And do not deposit more than you can afford to lose, whether it is via phone or any other method.
Is there a fee for pay by phone deposits?
Most UK casinos do not charge a fee for phone-bill deposits. The transaction cost is absorbed by the casino or the payment provider. Your mobile network may add a charge for premium SMS services, but pay by phone casino deposits are usually not premium-rate. Always check your phone bill after the first deposit to confirm no unexpected charges.
Can I use pay by phone on a pay-as-you-go plan?
Yes, as long as you have enough credit. The deposit amount is deducted from your prepaid balance immediately. If your balance is lower than the deposit amount, the transaction will fail. This is a useful way to manage spending because you can only deposit what you have already paid for in advance.
What happens if I lose my phone or change my number?
If you lose your phone, your casino account is still protected by your password and any two-factor authentication you set up. The pay by phone number is just a billing identifier; it does not grant access to your casino account. If you change your number, update it in the casino cashier before making another deposit. The old number will no longer work for billing once your mobile provider reassigns it.
