Fonix is the UK's leading mobile SMS and Carrier Billing mobile aggregator. For gamblers, this means that you can deposit using Fonix at online casinos that support pay by mobile powered by this service.
Fonix was founded in 2006 and listed on the London Stock Exchange in 2020. Its clients include Daily Mail, Channel 5, and ITV, among others. In addition to the UK, Fonix now operates in Ireland, Germany, and Austria.
In many ways, Fonix is similar to Boku and PayForIt, as each of these brands allows you to deposit using your phone bill, and they all have relatively low daily spending limits. Still, with Fonix, you can deposit up to £40 daily, which is slightly more than the £30 daily limits on Boku casinos and PayForIt casinos.
To use Fonix at online casinos, you only need your phone within reach. You don't need to sign up with a third-party service provider or give your card details.
Here's how you can deposit at online casinos with Fonix:
💡 The minimum sum you can deposit with Fonix is £10.
💡 The most you can deposit per day varies between £30 and £40, depending on the casino. The maximum limit for monthly transactions via Fonix is £240.
💡 Fonix doesn't charge deposit fees, and the deposits are typically instant.
Fonix doesn't allow withdrawals from casinos.
To withdraw winnings from a casino, you must choose one of the alternative payment methods offered by the gambling site.
Typically, the alternative methods include at least Bank Transfers. You can affect the selection by making an additional deposit using a method other than Fonix. That way, this deposit method should also appear on the list of alternative options if it supports withdrawals.
This updated list includes the newest Fonix casinos. We are adding more new Fonix casinos as soon as they emerge, so you can enjoy a fresh experience with easy Fonix payments.
If you're eager to see more newcomers, our newest casinos page provides you with the latest UK brands.
When you register a new account with a Fonix casino, you can often receive a bonus to boost your first deposit—or, you can get a bonus for free, as some Fonix casinos can have promotions for no-deposit bonuses.
Here, we take a quick tour of casino bonuses you can potentially find on Fonix casino sites.
A first deposit bonus is a treat that casinos reserve for first-time depositors.
This is typically a bonus you can get only once for your first deposit at the casino. However, if you miss it because you didn't notice it required a manual activation, you might still get it if you contact the casino's support team.
A typical first deposit bonus at Fonix casinos is a 100% Match bonus up to a certain sum and some additional bonus spins. If you can't find the kind of bonus you're looking for at any of the Fonix casinos listed on this page, have a look at the UK's best casino bonuses.
When you get free game rounds from a casino without having to pay for them, they're called free spins. Casinos usually offer free spins for new members as a way to give them the easiest start on the games when they don't need to risk their own money.
A few Fonix casinos offer free spins at the moment, and all you need to do to claim them is to sign up and follow the casino's instructions. You can also check our no deposit free spins promotions currently available at other sites.
Like free spins, no-deposit bonuses are promotions that you can claim from a casino without spending a penny.
A no-deposit bonus is usually given as free spins, but it can also be money you can play on the games of your own choice. Additionally, it can be free bingo tickets or even free betting slips. Essentially, anything can be a no-deposit bonus as long as you get it from a casino for free.
See our best no deposit casino bonuses for more information.
There are several reasons that speak for using Fonix for gambling. First and foremost, Fonix is a safe and quick method to deposit money while also ensuring that gambling stays within set limits.
Fonix is also free to use, as it doesn't charge fees or require setting up an account. In addition, by using Fonix, you don't need to give out your card or bank details to a casino.
To properly weigh both sides, here are the pros and cons for you to consider before using Fonix.
Using Fonix doesn't require a downloadable app or signing up to a third-party service
Fonix is a safe and secure way to deposit money
Fonix limits gambling transactions to £40 per day, so it's an added layer to gambling responsibly
Fonix doesn't charge deposit fees
With Fonix, you can deposit now and pay it later on your next mobile bill
You can't use Fonix to withdraw funds from casinos
With the maximum daily transaction limit of £40, Fonix doesn't cut it for high rollers
Fonix isn't as widely available at online casinos when compared to eWallets, cards, etc
Smaller mobile carriers usually don't support mobile billing
Fonix is a safe payment option at UK casinos. With Fonix, you essentially use your mobile bill to pay your deposit, so you don't need to share your card details with casinos.
Fonix also uses two-factor authentication every time you deposit with it. This happens with a 4-digit code that Fonix sends you via SMS. You need the code at the casino where you're depositing to confirm the transaction.
Fonix is a great way to play casino games in UK online casinos. It gives you access to numerous different kinds of games that you can find at casino sites.
Here are some of the popular casino game categories.
It is easy to play slots with Fonix, as these games are available everywhere. Every casino site has some slots available, and a little shopping around gives you access to every game provider out there.
Table games are those classic casino games, such as roulette or blackjack. While these games don't have as many versions as other games, they are still easily available at Fonix casinos.
You can also enjoy live casino games with Fonix deposits. Live casino table games and game shows give you that social gaming feel that reminds us of brick-and-mortar casinos.
Online poker has become a bit of a rarer sight these days, but it is still available at a handful of UK casinos. Unfortunately, these casinos do not accept Fonix deposits, and you need to use other payment options to play poker.
Since you can't withdraw with Fonix, it's good to explore the alternative banking methods which you can use for withdrawals. Here are some popular options which allow cashing out.
Visa is a globally accepted payment card that UK residents can use for online casino gaming, but only the debit option due to the UKGC's regulations.
You can use a Visa debit card to deposit and withdraw funds at casinos. Deposits are instant, but withdrawals typically take 1-4 business days—sometimes even a week, depending on the casino. So, it's not the fastest withdrawal method, but easily the best option out there if you don't want to use eWallets.
Visa is also accepted by every UK-licensed casino, including Fonix casinos. See our list of casinos that accept Visa.
PayPal is an online wallet and payment service that you can link to your debit card or bank account. You can authorise PayPal to charge your card or transfer money to your PayPal account and use the funds there to deposit money at casinos.
PayPal transactions are typically fast. At some of the fastest-paying casinos, PayPal cashouts are in your bank within an hour. This makes PayPal one of the most popular banking methods, and its wide acceptance is another reason for this.

If you're hesitant about using your cards or eWallets, wire transfers are your final option for cashing out your casino winnings.
When the deposit method doesn't allow withdrawals, wire transfer is the most usual choice the casinos offer players who want their money out from a casino and haven't used any other deposit method.
Wire transfers are the slowest of the bank transfer methods. After requesting a withdrawal via wire transfer and the casino processing it, it can take up to 10 days to receive the money. However, sometimes bank transfer deposits are the only way to get your winnings.
Fonix casinos are online casinos where you can deposit money and pay for it with your phone bill. When you use Fonix to deposit, the sum gets charged to your next mobile bill, allowing you to play now and pay later.
Fonix is a relatively new mobile payment method in UK casinos, but it is quickly becoming more widely available. The advantages of using Fonix include its simplicity and the fact that there is no need to download additional apps. In addition, Fonix doesn't charge any fees.
Fonix is on its way to becoming one of the top choices for quick and effortless mobile payment options in the UK.
