Real-World Pay by Mobile Casino demo and field notes
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 auto-detected and the deposit screen gave me a single “Confirm £20” button—no SMS needed. Funds landed in <3 seconds. Easiest flow by far.
Boku + O2 (laptop on Wi-Fi): I entered my mobile, got an SMS asking me to reply “YES.” The reply cost nothing and the balance 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. Money came straight off my debit card, free of charge, and no £40 cap to worry about. Handy for bigger top-ups (£100+).
Google Pay + Three (Pixel): Fingerprint authentication in-app, instant credit. Not yet available at every casino, but when it is, the flow mirrors Apple Pay for Android users.

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.
