What is Fonix and how does it work at Casinos?
Fonix is a UK-based mobile payment platform that acts as an aggregator between companies and phone networks. Essentially, it 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 and Boku, Fonix Casinos will 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. Furthermore, Fonix can be used on all devices including tablet and desktop casino sites along with mobile.

Fonix Casinos offer some generous casino welcome bonuses and promotions including free spins, matched deposit bonuses as well as reload bonuses for returning players.

How we judge Fonix Casinos
We take several criteria into action when making our best online casino site recommendations. As well as the obvious being accepting Fonix as a payment method we also look at the overall casino experience before advising players to check out a particular site. Below you’ll find the main features we look for in a Fonix Casino:
Licenced and Secure
All of the casinos we recommend hold United Kingdom Gambling Commission (UKGC) licenses. This is to ensure a safe and secure gambling experience and that the casino meets the highest standard of fairness and has responsible gambling measures in place.
Welcome Bonus
As avid bonus hunters, we know what promotions will actually offer value. That’s why we always look for the best casino bonuses and sign-up offers that provide good returns as well as a great way to kickstart your casino experience.
Game Variety
We always consider a casino’s game selection when deciding which casinos to recommend. After all, the games are the most important aspect, so we always examine the slot selection, casino providers, live casino options, and any other genres offered.
Payment Methods
Naturally, Fonix Casinos should have a Pay by Mobile option to ensure Fonix is available but we also look for a good range of payment options, speedy withdrawals and minimal to zero transaction fees.
Customer Support
A wide range of customer support channels is only half of what makes good customer service. We also look at how helpful, knowledgeable and friendly the agents are, ensuring good support if an issue arises.
User Experience
This involves looking at the overall usability of a site, encompassing all aspects of the site including aesthetics, navigation and design of the site and how it creates the overall experience.
Fonix Casino Alternatives
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. While both PayPal and Fonix offer quick deposits, PayPal also allows for withdrawals and offers more flexibility with transaction amounts, but requires account creation, which Fonix avoids.
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 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. However, its availability depends on whether your bank is supported by Trustly and if the casino offers it as a payment option. Compared to Fonix, Trustly facilitates both deposits and withdrawals and handles larger transaction amounts, but requires a more involved process of selecting your bank and authorising the transfer, whereas Fonix simply charges it to your phone bill.
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 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. Unlike Fonix, Apple Pay Casinos can be used for both deposits and withdrawals, but it requires an Apple device and linking to a card or bank account. Fonix’s simplicity lies in its direct billing to your mobile phone.
Fonix Casinos – The Fruity Slots Verdict
Fonix offers a great Pay By Mobile service that requires little to no set-up and is easy to use. Whilst the £40 a day limit encourages responsible gambling, this combined with the £240 maximum monthly limit makes it better suited to those who make lower casino deposits. If using a Fonix Casino, players will require a separate withdrawal method like Visa, Mastercard, Neteller or bank transfer.
While it may not yet be universally accepted, Fonix is growing in popularity and its ease of use appeals to mobile-first players. For quick, secure, small-scale deposits charged to your phone bill, Fonix casinos are a valuable option, particularly with the welcome bonuses we’ve highlighted.
