Mobile casino payments have advanced a lot since the early days of “pay by mobile phone bill” options at online casinos, but many UK players still prefer this traditional option. Fonix is a phone payment operator which launched in 2006, and has more than 28 million users in 2026. While it’s getting harder to find online casinos that accept Fonix, our experts have done the hard work for you, tracking down the best options on the market. Below, you can find a list of the top Fonix casinos, advice on how to find your ideal gambling sites, and much more.

When one of our Gamblizard experts is assigned a casino review, they work from a list of 7 primary criteria and 32 subcriteria to evaluate the most important aspects of each site. Each feature is given a score, which is then weighted based on its importance to the overall casino experience, as seen in the diagram below:
We use these scores to create an overall rating for the casino:
You can find out more about how our scores are calculated by consulting the How We Rank Casinos page.
While most comparison sites would assign the casino a score and call it a day, we dig deeper to find the brands that offer the best value to our readers. We start by setting the standards that a Fonix casino needs to meet to make it onto our recommendations. Our experts scour our database of casinos to find which sites meet our strict requirements. We then compare qualitative features such as the gameplay experience and user interface to create our definitive ranking of the best pay by Fonix casino sites.
Selection Standards:

Even with our expert recommendations, we understand that it can be hard to find a site that fits your needs. To make this process easier, our experts have highlighted the key features you should look for when choosing the best Fonix casinos.
Fonix does not support withdrawals from online casinos, so it’s important to check what options are available to you when you want to cash out your winnings. Some Fonix online casinos will impose high withdrawal limits or costly fees to these transactions, so we recommend comparing the withdrawal policy at multiple casinos to find a low-cost option.
According to our findings, some casino bonuses cannot be claimed with Fonix deposits. If claiming online casino promo codes is important to you, take the time to read the conditions of the offer before you sign up. You can find a list of excluded payments in the T&Cs, as well as other important information, such as wagering requirements, maximum win limits, and game restrictions.
While Fonix carries out KYC verification during the payment process, some sites will require additional documentation before you can withdraw. To avoid lengthy delays when cashing out, check your casino’s verification policies before signing up. If you know that your casino will require proof of ID documentation before withdrawal, we recommend completing the verification process as soon as possible, as this will help expedite your payment.
If you’re making online casino payments via your phone or table device, it’s likely that mobile gameplay is an important factor when choosing your gambling sites. Rather than waiting until you’ve joined, we recommend testing all available mobile platforms on your device before signing up.
This will tell you if the site has a compatible mobile app for your device, and give you a first hand look at the casino’s user-interface and responsiveness. While trying it out, ask yourself, “Can I see myself using this app to play my favourite games?” If the answer’s yes, you’ve likely found a good place to play!
While making online casino deposits at casinos with Fonix is easy, you cannot use this payment method to cash out your winnings. Instead, you must use an alternative payment method when making withdrawals.
Making a Fonix casino deposit is a simple process that takes less than 60 seconds to complete. Follow the guide below to get started:
After you have approved the payment, the deposit will be processed instantly, and will be waiting in your account.
As Fonix does not support casino withdrawals, you must choose an alternative banking method. The majority of Fonix online casino sites will allow you to cash out via a bank transfer if your primary deposit method is not available.
To start this process, follow our helpful walkthrough:
The Fonix Identify feature lets gambling sites verify your mobile number and your personal information during the deposit process. One of the benefits of this feature is its speed; once you have submitted your payment, verification is completed within a couple of seconds. This painless verification procedure helps to avoid delays and makes it easier for you to start playing your favourite games.
Here’s what the Fonix Identify feature checks when you make your payment:
Fonix casinos are an excellent entry point for beginners, as they offer a seamless way to play with smaller amounts while staying within strict budget limits. By removing the need to share banking details, Fonix provides a vital layer of security against potential data breaches. However, in 2026, the absence of withdrawal support and relatively low deposit caps mean that high rollers or those seeking all-in-one solutions might find better alternatives.
