Pay by Mobile Casinos UK 2026: Phone Bill Deposits Explained
Phone bill deposits are small by design: networks cap them at £40 a payment and £240 a month. Here is how pay by mobile works at licensed casinos.
A pay by mobile casino lets you deposit by charging the amount to your mobile phone account, with no card or bank details involved. Among the more than seventy Gambling Commission-licensed operators covered on All British Casinos, Amazon Slots is still the only one that lists Pay by Mobile as a deposit method; the larger groups reviewed since lean on Apple Pay, Google Pay and Pay by Bank instead. The method comes with hard limits set by the mobile networks, and it is usually deposit-only, so you need a second method to withdraw.

How phone bill casino deposits work
In the cashier you choose pay by mobile, enter your number and the amount, then confirm the payment, usually by replying to a text message. The charge is then collected by your mobile network. The payment is processed by a carrier billing provider; Boku and Fonix (which runs Payforit) are examples of services used for charge-to-bill payments in the UK.
Amazon Slots describes depositing from £10 by debit card, PayPal or Pay by Mobile, in GBP only, and requires every payment method to be in the name of the registered player. If the phone contract is in someone else's name, the deposit should not be made.
The £40 and £240 caps on charge-to-bill payments
UK mobile networks cap charge-to-bill payments at £40 per transaction and £240 per month per account, under payment services rules. That ceiling applies on top of anything the casino sets, so pay by mobile slots sites cannot take a large deposit by phone even if you ask. Any gambling-specific cap a particular operator applies within that is set out in its own cashier and terms.
These caps are not a substitute for your own limits. GB-licensed sites ask you to set a deposit limit before the first deposit, and since 30 September 2026 operators must offer gross deposit limits that count every deposit in the period. Pick a figure that suits your budget rather than the network maximum; the deposit limits guide explains how each type of limit works.
Withdrawing when you deposit by phone bill
Money cannot be paid back to a phone bill, so pay by mobile is usually deposit-only. Before you deposit, add a withdrawal method in your own name, such as a debit card or PayPal, and complete any ID checks. Operators may ask for documents before paying a withdrawal, and reverse withdrawals have been banned in Great Britain since October 2021. Payout speed then depends on the method you withdraw to - see fast withdrawal casinos.
Mobile slots and the welcome offer
Amazon Slots currently lists Chance to win up to 500 bonus spins on Starburst.
18+, new players, £10 min fund; bonus spins winnings subject to 10x wagering; max bonus conversion equal to lifetime deposits up to £250; only bonus wagers count
Its £10 minimum fits inside the £40 network cap, but check the promotion's full terms for any payment exclusions before making a qualifying deposit by phone. GB rules have capped wagering on bonus funds at 10x since 19 January 2026.
On slot games, the stake limit is £5 per spin, or £2 if you are 18-24. Spins cannot be run on autoplay at GB-licensed casinos, and each spin takes at least 2.5 seconds. For the games themselves, see online slots.
Is pay by mobile right for you?
- Suits: small, occasional deposits, and players who do not want card details stored at a casino.
- Less suited: anyone who wants one method for paying in and cashing out, or larger deposits.
- Check: the operator's Gambling Commission account number on the public register, the mobile deposit minimum and the withdrawal method you will use.
A phone bill arrives weeks later, which makes it easy to lose track of what you have spent. Keep a note of each deposit or check the account history in the cashier.
