What is the Pay by Mobile Payment Method?
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 to carry out a pay by mobile casino deposit:
Use your mobile phone contract (i.e., your monthly phone bill)
Deposit using a pay-as-you-go (PAYG) mobile phone contract.
Pay by Mobile Phone Bill UK Regulations
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 caps of £40 daily / £240 monthly, as well as the double-opt-in SMS rule.
How Pay by Phone Bill Casinos Work

UK Mobile Network Compatibility & Performance
All four major UK operators support carrier-billing deposits, but each has its quirks. Use the table below to see how your network stacks up.
Ensure your personal “Spend Cap” in the Three app is set to a non-zero value, or deposits will be blocked.
*Spending caps are mandated by UK carrier-billing rules and apply network-wide.
How to Deposit at a Pay by Mobile Casino
Whether you’re on Pay-Monthly or PAYG, the steps below take under a minute:
Open the casino deposit screen.
Select “Pay by Mobile / Phone Bill”.
Enter (or confirm) the amount you want to deposit.
On mobile data, your number is detected automatically; on Wi-Fi, you type your UK mobile number.

• One-tap “Yes, charge £X” prompt or
• Enter the SMS one-time code sent to your phone.
The casino balance is credited instantly.
Pay by Mobile Casino Deposit Limits
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.
Pay by Mobile Casino Deposit Fees
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.
How To Withdraw From Casinos with Pay by Mobile
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.

Simple deposit process: Depositing at a pay by mobile casino is easy. It only requires a few steps and SMS confirmation, making it a secure and user-friendly option.

Bonus availability: Pay-by-mobile casinos offer a range of bonuses, including welcome offers, free spins, and reload bonuses. However, deposit limits may affect the size of the bonuses.

Real-World Pay by Mobile Casino Demo
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.
Left: £20 deposit confirmed inside the casino cashier.
Right: SMS with one-time code (1234) used to verify the charge.
Chris Vaughan’s Field Notes
Fonix + EE (iPhone): While on 5G, my number was automatically detected, and the deposit screen displayed a single “Confirm £20” button—no SMS was needed. Funds landed in <3 seconds. Most effortless flow by far.
Boku + O2 (laptop on Wi-Fi): I entered my mobile number, and I received an SMS asking me to reply with “YES.” The reply cost nothing, and the balance was updated in about ten seconds. Slightly slower but still painless.
Siru Mobile + Three (Android): Siru sent a 4-digit code via SMS. Entering the code worked, but Siru added a £0.60 fee on my £10 test—worth noting if you’re fee-sensitive.
Apple Pay + Vodafone (iPad): Face ID + double-tap and done. The money was deducted straight from my debit card, free of charge, and there was no £40 cap to worry about. Handy for bigger top-ups (£100+).
Google Pay + Three (Pixel): In-app fingerprint authentication and instant credit. Not yet available at every casino, but when it is, the flow mirrors Apple Pay for Android users.
Sky Mobile Pay by Phone Casino Deposits
Sky Mobile Pay by Phone Casino options mirror the O2 carrier-billing flow (Sky runs on O2’s network), so you can fund your account in seconds and settle up on your next mobile invoice. The process uses Payforit rails—usually Boku or Fonix—so deposits slide under the same £40 daily / £240 monthly safety cap.
How to Deposit with Sky Mobile
Open the casino cashier on 4G/5G (header-enrichment auto-detects your number).
Select Pay by Phone / Boku / Pay by Mobile and enter the amount (min £5, max £30).
Tap Confirm £X or reply “YES” to the SMS—Sky routes the charge to your next bill or deducts it from any PAYG balance.
Balance credits are instantly applied; the charge appears under Extras → Premium Services in the My Sky app.
Sky-Specific Quirks & Workarounds
Spend Control toggle: defaults to £40; adjust it to lower or raise the limit in My Sky → Spending Controls.
Wi-Fi Calling: disable during the deposit step; header enrichment requires mobile data.
Roaming: Sky blocks carrier billing outside the UK, so top up before you travel.
Tesco Pay by Phone Casino Deposits
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 utilises the Payforit platform, often powered by providers such as Boku or Fonix, ensuring secure and regulated transactions.
How to Deposit with Tesco Mobile
Open the casino cashier page on your mobile device connected to Tesco Mobile’s network (4G/5G).
Select “Pay by Phone,” “Pay by Mobile,” or a similar option such as Boku or Payforit.
Enter the deposit amount (typically between £5 and £30).
Confirm your deposit by tapping “Confirm £X” or replying “YES” to the SMS verification message sent to your phone.
Your deposit will be instantly credited to your casino account, and the charge will appear on your next Tesco Mobile phone bill or deducted from your pay-as-you-go credit.
Tesco Mobile Casino Tips
Spend Controls: Tesco Mobile enforces the standard £40 daily and £240 monthly limits for Payforit transactions, but you can manage or adjust these limits via your Tesco Mobile account settings.
Prepaid Credit: Deposits can only be charged against your available airtime balance or contract billing; bonus or rolled-over data cannot be used for deposits.
Network Coverage: Ensure you have a strong Tesco Mobile signal and mobile data enabled during the deposit process, as Wi-Fi or roaming may interfere with the verification process.
Roaming Restrictions: Tesco Mobile carrier billing is only available within the UK. Deposits will fail if you try to use Pay by Mobile while roaming abroad.
Billing Queries: Charges for casino deposits appear under “Premium Services” on your Tesco Mobile bill, so check there if you want to verify transactions.
Mobile Deposit Casino Alternatives
In addition to the more direct pay by mobile method, there are other options. If you are looking for mobile payment options, here are the most popular:
£30–£40 cap unsuitable for high rollers, no phone bill withdrawals, occasional casino surcharge, and some MVNOs are blocked.
Workarounds when capped
Switch to Apple Pay, Google Pay, a debit card, or an e-wallet for higher or top-up withdrawals; caps are reset every 24 hours.
Key takeaways
Fast and private for micro-stakes; read the cashier preview and T&Cs for hidden fees; choose EE/Three for the fastest one-tap flow, O2 for granular spend control, or Vodafone after a 90-day probation period.

Pay by Mobile Casino FAQs
Depositing to a casino by your phone bill makes things very easy.
The main advantages of pay-by-phone-bill casinos are convenience, security and fast deposits. Plus, as most UK players prefer to make a real money bet on their iPhones and Androids, it makes a lot of sense. Just ensure you have another payment option for making withdrawals.
It appears as a single line under “Premium Services” (or similar) with the amount and a generic descriptor, not the casino’s full brand name; you settle it along with your regular airtime charges.
Carrier billing is a one-way deposit channel only; regulatory rules and telecom systems don’t support crediting funds from the casino back onto a phone bill.
Yes, you can request a “premium rate bar” from your mobile network or set a spend stop with the PSP, and the casino must honour any self-exclusion on top.
Funds appear instantly using Pay by Mobile as a depositing method—typically within one to three seconds of entering the SMS PIN or pressing “Yes” on the carrier confirmation page.
It charges your deposit straight to your phone bill in real time: you enter your mobile number, confirm the SMS PIN, the PSP bills your carrier, and the casino credits your balance instantly while the charge shows up on your next statement or is taken from PAYG credit. Read our in-depth How it Works Guide.
All four major carriers—EE, O2, Vodafone and Three—plus most of their MVNO sub-brands allow carrier-billed gambling payments through approved PSPs such as Boku and Fonix.
Yes, but you’ll need to type your mobile number manually and confirm the charge by replying to an SMS or entering a one-time PIN because the network can’t auto-detect your device over Wi-Fi.
Usually yes, but some sites exclude carrier-billing methods in the small print from. Always check the bonus terms before depositing.
The most common reasons are hitting the £40 daily carrier cap, having a premium-rate bar on your account, or trying to use the service within a new-contract waiting period.
No, carrier-billed payments are exempt because the charge is treated as telecom spend rather than a line of consumer credit.
No, the £40 per-day / £240 per-month cap is mandated across all UK networks and cannot be raised, but you can lower it or apply personal spend bars for extra control.
Yes, as long as the eSIM is on a UK carrier that supports direct billing; the network treats eSIM numbers the same as physical SIMs for premium charges.
The carrier will apply late fees and may suspend your service; the casino keeps the funds because the operator—not you—advanced the payment at the time of deposit.
No, payment providers pass the casino an encrypted alias or token, so your actual MSISDN remains private under GDPR rules.
