Pay by SMS Casinos in the UK: Deposit by Phone Bill from £10

What Is a Pay by SMS Casino?

A Pay by SMS site lets you add funds through the cashier without entering card or bank details. The charge is confirmed from your mobile phone and then added to your next bill or taken from your pay-as-you-go credit.

Pay by SMS deposits are processed through carrier-billing providers such as Boku and Fonix, which route the payment between the casino and your mobile network. Both work with EE, O2, Vodafone and Three. The casino chooses which provider it uses — you do not select this yourself.

Best Pay by SMS Casinos in the UK (October 2026)

We focused on UKGC-licensed sites where Pay by SMS is available as a real cashier option, not just mentioned in old payment guides.

The daily cap is set by your mobile network, not the casino. EE and O2 fix it at £40 per transaction. Across all four networks, the monthly maximum is £240 — a regulatory cap that applies to all phone-bill payments in the UK and cannot be increased.

Great Britain Casino

Great Britain Casino supports Pay by Mobile deposits from £10. They have 4,520+ slots, while the casino also lists roulette, blackjack, baccarat, game shows, poker, bingo, scratchcards, instant-win titles and live dealer games. The site is optimised for mobile play, so the cashier and games can be accessed from a phone without using card or bank details for this deposit method. Pay by Mobile is deposit-only, so withdrawals require another available payment option.

How We Rank Pay by SMS Casinos

We list only UKGC-licensed sites and check each operator against the public register. Our review covers supported mobile networks, deposit limits, processing speed, bonus eligibility, withdrawal options and safer gambling tools. We update the information regularly to reflect changes in payment terms and availability. Carrier billing suits small top-ups, which is why some operators that let you deposit £4 on casino side support it.

How to Deposit by SMS, Step by Step

Depositing by SMS usually takes less than a minute once your account is ready. Before you deposit, check the cashier for any Pay by SMS fee to avoid unexpected charges. Button names and their location may vary by operator, but the typical process looks like this:

1. Register at a UKGC-licensed Pay by SMS site and complete any required account checks.
2. Open the cashier and select “Pay by Mobile” or “Pay by SMS”.
3. Enter your mobile number and choose the deposit amount.
4. Check the text message sent to your phone and confirm the charge by reply or PIN.
5. Wait for the balance to update, usually instantly.
6. Check that the amount appears on your phone bill or has been deducted from your pay-as-you-go credit.

Which Casinos Accept SMS Deposits — and Why Some Don't

We found 30 UK casino sites that accept pay-by-SMS or pay-by-mobile deposits. The number remains relatively small because operators require a specialised mobile billing integration, and processing costs can be higher than for card or bank payments.

For casinos that accept pay-by-SMS, availability depends on the cashier setup rather than brand size or the UKGC licence. Such a platform must connect to a carrier-billing service, support the relevant mobile networks and decide whether the economics work for low-value deposits.

UK mobile networks commonly cap qualifying transactions at £40 each and £240 per month. These limits apply across relevant phone-paid transactions, not separately at each casino. Pay by SMS is deposit-only, so online casinos that accept SMS deposits still need another withdrawal method.

Boku

Boku is a direct carrier billing provider. At UK Boku casinos, players enter their mobile number, receive an SMS one-time password and confirm the payment before the charge is added to a monthly bill or deducted from prepaid credit. In the UK, the service can work with EE, O2, Vodafone and Three. Mobile-billing limits are up to £40 per transaction and £240 per month.

Fonix

Fonix provides carrier billing to sectors including online gaming. A Fonix casino can use the player’s mobile number for the deposit, with two-factor authentication completed through a four-digit PIN sent to the handset. Fonix publishes a £40 UK daily spend limit and a £240 monthly limit. Its UK carrier-billing coverage includes EE, O2, Vodafone and Three, although the exact checkout flow can vary by operator.

Payforit

Payforit is better understood as a standardised UK mobile-payment journey than as a provider identical to Boku or Fonix. The flow lets a payment intermediary identify the mobile account, obtain the user’s approval and send the charge to the network for billing or deduction from prepaid credit. A Payforit casino can use the standard across EE, O2, Vodafone and Three, with the same £40/£240 mobile-billing limits applying.

Some major brands do not list SMS among their current deposit methods. For users comparing casinos that don’t accept SMS deposits, Virgin Bet lists Apple Pay and Pay by Bank, while bet365 offers Apple Pay, Google Pay and Pay by Bank. William Hill also supports Pay by Bank. These alternatives avoid mobile-billing limits and can support withdrawals in some cases.

When you top up your account via Pay by SMS (listed at these casinos as Pay by Mobile), you can get a welcome package with bonus funds, free spins, or both. Below are examples of current promotions with their main conditions:

Are Pay by SMS Withdrawals Available?

You cannot withdraw winnings by SMS or send payouts back to your phone bill. If a site claims to offer Pay by SMS withdrawals, treat it as a warning sign and check its UKGC licence before registering. Licensed UK operators use Pay by SMS for deposits only.

To cash out, choose a separate withdrawal method in the cashier, such as a debit card, PayPal, bank transfer or another available option. You will also need to complete identity verification before any payout is processed.

Pros and Cons of Pay by SMS Casinos

Pay by SMS is mainly useful for smaller mobile deposits where speed and spending control matter more than high limits or payout flexibility. Use the table below to compare the main advantages and limitations:

UKGC Licensing and the 2026 Rules You Should Know

Every pay by SMS casino we list is licensed by the UK Gambling Commission and bound by the LCCP. A few 2026 rule changes affect how deposits, bonuses and player checks work in practice:

• Bonus wagering is capped at 10x the deposit-plus-bonus amount (in force from 19 January 2026), and mixed-product promotions are banned.
• From 30 September 2026, UK casinos can only call something a "deposit limit" if it's based purely on money paid in. For example, depositing £100 on Monday and £100 on Thursday uses up £200 of your limit, even if you withdrew money in between.
• Credit cards remain banned for all UK gambling — another reason debit, PayPal and phone-bill deposits are the norm.
• Financial-risk checks run quietly in the background once deposits minus withdrawals pass £150 in a rolling 30-day period, with no impact on play for most users.

Pay by SMS vs PayPal, Debit Card and Trustly

Pay by SMS is useful for quick low-stakes deposits, but it works best alongside a separate withdrawal method. The table below compares SMS billing with PayPal, debit cards and Trustly:
