Casino Sites Accepting Fonix Payments – September 2025
What is Fonix and How Does it Work at Casinos?
Fonix is a UK-based mobile payment platform that allows purchases to be made anywhere that accepts Pay By Phone and adds the amount to your next mobile bill. Recently it has become a more prominent payment method for gamblers, with more and more switching to mobile as their primary device for using casinos.
Similar to other Pay by Mobile options such as Payforit, Fonix Casinos allow you to charge the deposit amount to your monthly phone bill. Fonix can be used with all major mobile networks including Vodafone, Three, EE and O2.
Pay by Phone options such as Fonix provide players with a safe, secure and quick way to make deposits, without having to share any personal information with a casino. Plus, Fonix can be used on all devices including tablet and desktop casino sites along with mobile.
Tip: Fonix cannot be used for withdrawals, so you’ll need to choose another payment method. Don’t worry, all of the Fonix online casinos we recommend also have lots of fast, free withdrawal methods

Fonix Casino Complimentary Payment Methods
Since Fonix can only be used for deposits, it’s always a good idea to have another payment method lined up for withdrawals to get access to your winnings! We’ve outlined some alternatives below, as well as highlighted how they compare against Fonix casinos.
PayPal is an e-wallet service that allows users to store funds and make online transactions. It requires creating a PayPal account and linking it to a bank account or card. PayPal casino transactions are usually very fast, with both deposits and withdrawals often processed within minutes or hours, depending on the casino. This speed, combined with its widespread acceptance at UK casinos, makes it a popular choice.
Trustly is an online banking payment method that facilitates direct bank transfers without requiring card details. It acts as a middleman between your bank and the casino. Trustly casino deposits are typically instant, and withdrawals are often processed much faster than traditional bank transfers, sometimes within a few hours or a day. This speed, combined with its security and direct bank connection, makes it a popular alternative to standard bank transfers.
Mobile e-wallets like Apple Pay allow for quick and secure transactions using fingerprint or facial recognition. Like Fonix, Apple Pay is also primarily used by mobile players but it is exclusively for iOS users. Apple Pay casino deposits are generally instant, and some casinos offer fast withdrawals to Apple Pay, often processing them within a few hours. This makes it a popular choice for mobile users seeking speed and convenience. However, it’s limited to Apple device users and not all UK casinos accept it
