Paying by phone bill is a way to make a casino deposit that is easy, secure, and quick. Boku, Fonix and Siru are the most popular pay by mobile options in the UK in 2025. You can compare networks below. There are two ways in which to carry out a pay by mobile casino deposit:
Carrier billing is the telecom payment rail that powers Pay-by-Mobile deposits.
In the UK, it is regulated by Ofcom under the PSA Code of Practice v15, which sets the mandatory £40 daily / £240 monthly caps and the double-opt-in SMS rule.
When depositing to an online casino with your phone bill, you will be asked to verify via SMS. Here are the steps in more detail. We have created a dedicated how to guide, walking you through the steps of making a pay by phone bill deposit. If you encounter any errors or issues during the process, you can also check out our pay by mobile troubleshooting guide.
All four major UK operators support carrier-billing deposits, but each has its own quirks. Use the table below to see how your network stacks up.
| Mobile Network | Carrier Billing Supported? |
Auto Number Detection (Header Enrichment) |
Daily / Monthly Spend Cap* |
Common Hurdles & Tips |
|---|---|---|---|---|
| EE | Yes – Pay Monthly & PAYG | ✔ (one-tap confirm on data) | £40 / £240 | Some accounts start with “Charge to Bill” barred. |
| O2 | Yes – Charge to Mobile | ✔ | £40 / £240 | Always prompts a secure O2 page or SMS PIN for 2-factor confirmation. |
| Vodafone | Yes – Add to Plan / PAYG | ✔ | £40 / £240 | New contracts (< 3 months) can’t use carrier billing until the probation period ends. |
| Three | Yes – Three Pay | ✔ | £40 / £240 | Make sure your personal “Spend Cap” in the Three app isn’t set to £0, or deposits will be blocked. |
*Spending caps are mandated by UK carrier-billing rules and apply network-wide.
Whether you’re on Pay-Monthly or PAYG, the steps below take under a minute:
There is a hard limit in place when making a pay by phone bill casino deposit. The maximum deposit limit for pay-by-phone casinos is £30. You can, of course, make many of these mobile phone bill deposits throughout the month. However, you are limited to £30 over 24 hours. You'll need to wait a day to make another mobile phone deposit. The minimum deposit amount is usually £10 at most sites. Some UK online casinos drop this limit to just £5.
Some pay by mobile deposit casino sites charge 5-15% fees when using a pay by phone bill option. However, many casinos shoulder the cost, so that a player does not incur any extra fees of using the pay by mobile option.
You cannot withdraw funds using the pay-by-phone bill method. Therefore, you’ll need to choose other payment methods. You can check out our list of the fastest withdrawal casinos for more info on the best payment methods.
Here is a first-hand experience of using pay by mobile casino deposits at UK casinos. It has been captured and written by Chris Vaughan, Senior Editor at GamblingAuthority.

The process uses Payforit rails—usually Boku or Fonix—so deposits slide under the same £40 daily / £240 monthly safety cap.
When you deposit using Tesco Mobile, your casino deposit is added to your monthly Tesco Mobile phone bill or deducted from your prepaid credit balance. The process uses the Payforit platform, often powered by providers like Boku or Fonix, ensuring secure and regulated transactions.
