What "pay by mobile" actually means
Pay by mobile — also called carrier billing or pay by phone bill — routes the payment through your mobile network rather than your bank. You pick it at the cashier, enter your mobile number, confirm a code sent by text, and the money lands in your betting account. What happens next depends on your contract: on a monthly plan the amount is added to your next bill, and on pay as you go it comes out of the credit already on the phone.
In UK betting the provider doing the work behind the scenes is usually Boku, so a cashier may label the option "Boku", "pay by phone" or "mobile" and mean the same thing. If you already know the bookmaker you want to use supports it, our Boku betting sites page covers that provider in more detail.
Depositing by phone bill, step by step
The flow is deliberately short. Choose pay by mobile in the deposit screen, enter the amount and your mobile number, wait for the text message, and confirm it. The deposit is normally usable within seconds — as fast as a debit card, and faster than a bank transfer. You are never asked for long card numbers, a CVV or a banking app login, which is the main reason people who bet on a phone like it.
Limits, fees and the small print
Carrier billing carries lower ceilings than any other deposit method. Mobile networks cap how much third-party billing they will allow over a day and a month, and bookmakers usually add a per-transaction maximum on top. Expect to fund a modest account this way rather than a large one; if you routinely deposit more than a token amount, a debit card or e-wallet will be less frustrating.
Bookmakers do not generally charge for the method itself, but your network might: some tariffs treat third-party charges differently, and pay-as-you-go credit spent on a deposit is credit you no longer have for calls and data. Your phone contract, not the betting site, is the document that settles that question.
You cannot withdraw to a phone bill
There is no mechanism for sending money back up a phone bill, so every pay by mobile deposit leaves you needing a second method for withdrawals. Bookmakers normally ask you to withdraw to a debit card or to an account you have already deposited from, so it is worth adding one before you have winnings waiting. Our debit card and e-wallet pages cover the usual choices and how quickly each pays out.
Offers and payment-method exclusions
Welcome offers frequently exclude certain deposit methods from qualifying, and the exclusion list is written into the significant terms rather than the headline. E-wallets are the usual casualty, but carrier billing can be caught by the same clause, and a deposit made with an excluded method will not trigger the free bet however correctly you place the qualifying bet. Read the terms shown with any offer below before you fund the account, and if in doubt deposit with a debit card for the qualifying bet and use pay by mobile for top-ups afterwards.
How widely is it still available?
Availability has narrowed. Plenty of UK cashiers that once listed a pay by phone option have dropped it, so the honest answer for any specific bookmaker is the one on its own deposit page — check the payment methods listed there before signing up expecting to find it. Every operator we list holds a UK Gambling Commission licence, but the licence says nothing about which deposit methods a cashier happens to carry this month.
One safer-gambling point worth pausing on
On a monthly contract, depositing by phone bill means betting with money you have not paid yet and will not see leave your account until the bill arrives. That is a different feeling from watching a debit card balance drop, and it makes it easier to lose track. The 2020 ban on gambling with credit cards does not extend to carrier billing, so the guard rails here are the ones you set: use the deposit limits in your account settings, check your bill rather than your betting balance for the true total, and see our safer gambling page if the amounts are creeping up. GAMSTOP covers every UKGC-licensed site regardless of how you pay.
