Pay By Phone Bill Casino Comparison

We've rounded up the editor's favourite pay by phone casinos in the table below. Have a quick look and see which ones feel right for you.

What is a Pay by Phone Bill Casino?

A pay by phone bill casino is exactly what it sounds like – it’s a site that accepts payments through your mobile phone. When you pay via phone, you can charge the transaction to your bill at the end of the month. Or, if you’re on prepaid, the money will come straight out of your mobile credit balance.

What Makes a Good Pay by Phone Casino?

There are lots of factors that you need to consider when you’re signing up at a pay by mobile casino - here are just a few to note.

1. UKGC Gambling Licence – A good pay by phone casino always holds a valid licence for the UK - you can check these details in the footer of the site. It’s important that you only ever sign up and play at casinos licensed by the UK Gambling Commission (UKGC).
2. Quality Game Selection – The best pay by phone casinos offer hundreds or even thousands of slot games, plus live dealer games, and virtual table games. Some of the bigger names in online gambling also have a sportsbook, so you can place all your wagers in the same place.
3. Fast Alternative Withdrawals – You can't withdraw via Pay by Phone, and a good pay by mobile casino should offer fast payouts to e-wallets or other payment methods. 
4. Bonuses That Count – Welcome offers and ongoing promotions that don't exclude pay by phone deposits with fair wagering requirements.

Pros and Cons of Using Pay by Phone

Like all the best casino payment methods, there are a few pros and cons to using pay by phone at pay by mobile casinos. But don’t worry, the good outweighs the bad here.

Is it Safe to Deposit by Phone Bill?

Using pay by phone bill is just as safe as any other trustworthy online casino payment method, like bank cards or e-wallets. The payment comes from your mobile phone bill, so you don’t need to share personal details like your bank card or bank account number.

You also don’t need to worry about anyone billing online casino transactions to your phone bill, as you need to confirm the payment (usually via SMS). Any fraudsters would need access to your phone, too.

How Pay by Phone Bill Works (and How to get Started)

Using the pay by phone bill option at online casinos is very easy. Your deposit is either added to your monthly phone bill or deducted from your prepaid balance.

How Pay by Phone Bill Works

If you’re a prepaid customer, the money comes straight off your mobile phone credit. If you’re on a monthly contract, it's added to your next bill. Just remember to keep track of your online casino deposits, so there are no surprises when your bill arrives. 

How to Use Pay by Phone at Online Casinos

To start playing slots, table games, and live casino online at a pay by mobile casino, follow these steps:

1. Choose a pay by phone casino – Pick a trusted site from our list that supports Pay by Phone Bill or Pay Via Phone service.
2. Create an account – Sign up using your email and phone number.
3. Verify your identity – Upload a valid ID and proof of address.
4. Make a deposit – Select 'Pay by Phone' as your payment method and enter the amount.
5. Enter number – When prompted, input your mobile phone number.
6. Confirm the payment – Approve your transaction via SMS or a pop-up using PIN.
7. Check your balance – Funds will be instantly added and the amount. It'll be charged to your mobile bill or deducted from your PAYG balance.
8. Play – Start gaming with real money. 

Before you start using pay by phone casinos, there are a few things to keep in mind, like deposit limits, fees and fees you might run into.

Deposit Limits at Pay by Phone Casinos

All online casinos set minimum deposit amounts, and deposit by phone bill sites are no exception. Luckily, the pay via mobile option isn’t like a bank transfer, where you’d have to deposit £50 or more. The minimum amount for the pay by phone method is usually really reasonable.

The deposit limits vary depending on the online casino. In general, you’ll need to deposit at least £10 per transaction, though there are a few £5 deposit casino sites.

The maximum deposit with pay by mobile can be defined either by the casino or by your mobile provider, and in general it’s around £30 or £40 per transaction. 

Fees at Pay by Phone Casinos

The good new is that your mobile operator won’t charge extra fees for using pay by phone – it's a built-in service they offer. However, some pay by mobile casinos charge a fee for this payment method. 

This can vary widely depending on the site, from a small percentage (1–2%) to as much as 15% of your deposit. So, if you deposit £10, you'll be charged £1.5 in fees. Always check the cashier or terms before making payments.

You can pay by phone at the top UK online casinos in different ways. Either use your mobile phone credit, or have the payments show up on your phone bill next month. Here are some of the main ways to fund your account on mobile:

Pay by Phone Bill UK Casino

This is probably the easiest way to use the pay by mobile option. You confirm the transaction via an SMS, and the amount you deposited will be added to your phone bill at the end of the month. 

Pay with Phone Credit Casino

This option is for prepaid mobile phone customers. The money you deposit into your online casino account is taken straight from your phone credit. You’ll need to make sure your phone is topped up with enough money before you make the transaction.

Mobile Top-Up Casino

A mobile top-up casino lets you top up your balance via your phone, whether that’s by charging it to your phone bill or using a mobile-only method. Apple Pay is a popular option.

Pay by SMS Online Casino

When you pay by SMS, you’ll need to confirm your online casino transaction via a text message. Once your payment is confirmed through a code, the money will be taken from your mobile phone credit or added to your phone bill.

Several companies power pay by mobile payments at UK online casinos. Here are the main providers that enable players to deposit using their mobile number or phone bill.

Other Pay by Phone Casino (Not Boku) Options

Not all pay by phone casinos use Boku. Some rely on other mobile billing methods not powered by Boku, such as Fonix and Payforit.

Fonix

Fonix is pretty similar to Boku and PayForIt, so if you’ve used either of those, there are no surprises here. Fonix simply allows you to charge your online casino deposits to your mobile phone bill and you’ll pay for them at the end of the month.

You can deposit between £10 and £40 at a time and there’s a monthly cap of £240, so you won’t be able to lose track and run into any really nasty surprises later on. 

Payforit

PayForIt is a secure mobile payment framework that lets you add funds to your online casino account using your mobile phone balance or bill. Instead of entering card details or setting up an e-wallet, you can charge the deposit directly to your existing mobile account.

Because the payment comes from your available balance or monthly bill, there's no risk of running up unexpected bills. You can only spend the funds that you have. It's a convenient option for players who want more control of their budget and prefer to keep casino deposits separate from their bank accounts.

Payforit works with most of the top UK mobile phone networks, so if you're on one of the below, you’ll have no trouble using this service to top up your online casino account:

• Vodafone
• Virgin
• EE
• O2
• Three

While pay by mobile is a quick and easy way to deposit, you might want a bit more flexibility depending on your smartphone. Both Apple Pay and Google Pay let you make secure, instant deposits from your device without sharing your card details. Here's how they compare. 

The Best Pay by Phone Casino Bonuses

Most mobile casinos let you to claim special bonuses (both for new and regular players) when you use the pay by phone bill option. That means if you're at a pay by mobile casino, you can still take advantage of welcome offers and free spins.

It’s always a good idea to read the promo T&Cs thoroughly first though, as there are some promotions where only certain payment methods can be used to claim.

Best Pay By Mobile Slots

There are plenty of top-up-by-mobile slots. Your payment method usually doesn’t affect which games you can play, and at most top slot sites, you’ll be able to top up and play by phone with no trouble. 

If you're spinning on mobile, you've got the crème de la crème of the reels at your fingertips. Age of the Gods can drop Olympian jackpots straight into your palm, while Book of the Dead pairs high RTP with rewarding bonus features. Need something quick and flashy? Starburst dazzles in seconds. Prefer a relaxed pace? Big Bass Bonanza hooks wins at a steady, satisfying frequency. 

These are just a few top picks among mobile slots fans and are widely available at UK casinos that support phone bill payments. Below, I’ve listed some of the best pay by mobile slots with progressive jackpots. 

Casino Withdrawals with Pay by Phone

Casino withdrawals with pay by phone are a little more complex than deposits. If you’re using a mobile payment method like Apple Pay, the withdrawals work the same as bank cards, so you don’t need to do anything special. 

However, if you’ve billed an online casino transaction to your mobile phone bill, you can’t withdraw with it too. 

For that reason, you’ll need to select a different payment method for withdrawals, which is generally a bank transfer. Keep in mind that bank transfers could take up to 10 working days to reach your account.

Online Casino Pay by Phone Alternatives

Mobile phone bill isn’t the only way to deposit on mobile at UK online casinos. Other mobile-friendly payment options include digital wallets, debit cards, and online banking.

PayPal

Casinos that accept PayPal are really popular in the UK, both for deposits and withdrawals. If you don’t have a PayPal account, you can set one up within a matter of minutes and it’s good for all sorts of payments – not just online casinos.

PayPal is one of the most secure e-wallets out there, allowing you to link up your bank account, without sharing your bank details with the casino site.  It's great for fast withdrawals (much quicker than bank cards) and limits tend to be quite low, at around £10.

E-wallets: Skrill & Neteller

E-wallets like Skrill and Neteller are made for casino payments – they’re secure, easy to use, and help keep your casino transactions separate from your main bank account. 

Many casinos that accept Skrill offer fast deposits and withdrawals, but keep in mind that some sites don't let you claim bonuses when using this method. And the same applies to Neteller casinos. 

Trustly

If you want to use a bank transfer but want to skip the long waiting periods and hefty fees, Trustly casinos might be your perfect match. 

You don’t need a special card, an app, or any extra setup – just log to the casino, make your transaction, and watch the funds arrive in real time. Trustly also supports higher transaction limits than the pay by phone method, so it’s ideal for seasoned players or bigger budgets.

Debit Cards: Visa & Mastercard

You already use debit cards for just about everything, so why not for your casino deposits too? Casinos that accept Visa and Mastercard are everywhere, and it only takes a few seconds to enter your card details and confirm the payment. Even though withdrawals can take a few days to appear in your account, deposits are processed instantly. 

👉 Just remember that in the UK, only debit cards can be used for online gambling – credit card payments aren't allowed.

Should You Use Pay by Phone?

The online casino deposit method that suits you best will depend on your personal preferences, so paying by phone might not be for everyone. For example, if you want one payment method for both deposits and withdrawals, you might want to consider an alternative. Some other payments might also be better for easily tracking your transactions.

However, if you want a quick and safe solution to start playing now and pay at the end of the month, pay by phone bill might be the ideal method for you. A pay by mobile casino gives you the same convenience, letting you fund your account directly from your handset.
