Safety and Security of Pay by Phone Casinos
In the UK, when a player chooses Pay by Phone at a UK online casino, the merchant’s system makes a secure API call over TLS to a carrier-billing provider such as Boku, Payforit, Fonix or Siru. These companies partner with mobile networks to front the funds and settle instantly, logging each transaction with a unique ID for traceability.
All communications between the merchant, the provider and the mobile operator are encrypted with industry-standard TLS. No bank or card data is ever shared with the casino; only the player’s mobile number is transmitted. Provider platforms like Boku maintain ISO 27001–certified information security management systems and run continuous external assessments and bug bounty programs to detect and fix vulnerabilities.
Every deposit requires two-factor authentication. Players must confirm each transaction by responding to an text message one-time PIN or by answering a missed call and pressing a key on their handset. This step proves control of the phone number and stops unauthorised charges.
Regulators set mandatory deposit limits to curb excessive spending. Under the Payforit scheme, players cannot deposit more than £40 in 24 hours or £240 in a calendar month. Boku enforces a £30 cap per transaction (and per day) with a £240 rolling 30‑day limit. These caps help protect players by limiting potential losses, preventing sudden large deductions and supporting responsible gambling practices.
What is questionable about Pay by Phone, though, when it comes to responsible gambling, is that when you gamble on your phone bill, you’re essentially playing on credit. Which begs the question, why is this allowed while credit cards are banned for deposits? Limits are, of course, lower, but the idea remains the same.

Alternatives for Pay by Phone Casinos
In the UK online gambling market, the alternatives for Pay by Phone casinos would be:
Each of the methods offers a mobile-friendly and focused experience with some minor differences.
Pay by Phone vs Apple Pay
Apple Pay allows iOS users to deposit by tapping with Face ID or Touch ID. It uses tokenisation to secure card data and is widely supported on regulated UK casino sites.
Unlike Pay by Phone, Apple Pay supports higher transaction limits and can be used for both deposits and withdrawals via any linked card or bank account.
Pay by Phone option is, however, available on all mobile devices where whereas Apple Pay can only be used on Apple devices.
Pay by Phone vs Google Pay
Google Pay offers similar convenience on Android devices, using stored payment methods or wallet balances and biometric or passcode authentication. Its adoption among UK casinos has grown in recent years, but it isn’t very widely available.
Compared to Pay by Phone, Google Pay imposes no strict low‑value caps, but transactions rely on card networks rather than mobile carrier billing.
Pay by Phone vs PayPal
PayPal operates as a standalone e‑wallet, enabling both deposits and withdrawals with buyer‑protection policies and near‑instant processing.
It requires a PayPal account and sometimes incurs fees, but supports higher transaction values and withdrawal options that Pay by Phone does not.
The Bottom Line:
Apple Pay, Google Pay and PayPal provide broader functionality for larger sums and both deposit and withdrawal, while Pay by Phone delivers a highly secure, anonymous option for quick, low‑value deposits with built‑in spending caps to protect players.
