You want to deposit money into your online casino account, but you don't want to give out your personal banking details. Pay by Phone or Mobile Bill is one of the most secure ways of depositing funds into online casino sites. It’s quick and easy and doesn’t require sensitive banking information from you.

In most cases, you will still qualify for casino offers but always read the Terms & Conditions (T&Cs) to check if you’re eligible. If you have a mobile phone with a UK number, then this is how you can pay for items using your Pay As You Go or pay monthly phone bill/contract as currency with Boku or Payforit, without using bank details or eWallet methods.

What are Pay By Phone Casinos?

Pay by Phone Casinos banner

Pay By Phone casino sites are mobile casinos that allow their customers to deposit via their mobile phone bill or prepaid balance. As long as you have a UK SIM card/telephone number, you can use a Pay by Phone payment method at available casinos.

Different Names
You may see the mobile banking option referred to as: Pay By Phone, Pay By Mobile, Pay Via Phone, Charge to Mobile, Charge to Bill + Mobile Pay.

When you deposit at Pay by Phone online casinos, you’ll be charged depending on the type of mobile account you have:

  • Mobile Phone Bill: If you’re on a pay monthly contract, the deposit amounts will be added to your bill at the end of the month.
  • Pay As You Go: The deposit amount will be taken instantly from your prepaid balance.

With more and more of us using smartphones for everyday life, the rise of mobile deposit options has expanded significantly. The Gambling Commission’s online tracker survey in 2021 shows that 60% of online gamblers have used a mobile phone to gamble on.

The most popular Pay By Phone methods include Payforit, Fonix, Boku and Siru Mobile. Here’s a little about each mobile deposit method:

  • Pay By Mobile: Operated by Fonix, casino sites can allow customers to deposit via mobile carrier billing. A responsible gaming payment method, there is a daily spend limit of £40 in the UK which was set by the PSA. There is a monthly spend limit of £240. Once selected, you can verify your deposit with a 4-digit PIN. No financial information is required or shared with your chosen online casino either.
  • Payforit: Payforit allows you to deposit directly into a casino with the amount added to your next phone bill or deducted from your prepaid balance. Supported by all major UK mobile service providers, it’s a quick and easy way to deposit. With no payment details revealed, there are deposit limits (£40 per day and £240 a month).
  • Boku: Boku is available in over 90 countries and is chosen by over 28 million active users. With no Boku account to create or an app to download, Boku is free to use. Simply enter your mobile number if you’re on EE, Vodafone, O2 and 3. There is a £30 deposit limit per day with a minimum deposit of just £10. When you deposit, you’ll receive an SMS message which you need to confirm. It’s so simple.
  • Siru Mobile: Calling themselves the world’s easiest mobile payment method, you can use Siru Mobile and both Videoslots and Mr Vegas. Enter the amount you want to deposit and confirm the transaction by reply to the SMS message. There are fees ranging from 25% to 33% though.

No Withdrawals Using Pay By Phone

The downside to playing at Pay By Phone casinos is that you cannot withdraw your funds back to your mobile phone account. You probably don’t want to add £500 credit to your phone bill. If you manage to win big, your need problem will arise. It will require you to possibly contact an online casino’s customer service department to discuss the options you have.

Inevitably, it means you will need to choose a withdrawal method to receive your winnings. There are plenty of options including e-wallets (like PayPal) and debit cards. Below are a few options you have:  

  • PayPal: PayPal is arguably the most popular way to deposit and withdraw funds at gambling sites. Quick and pain-free, there are over 431 million PayPal users worldwide (as of May 2024) and is popular with online retailers such as eBay. Widely accepted in the UK including ASOS, Nike, Boots and River Island, PayPal offers a high level of security, is available for all casino bonuses and ensures fast withdrawals.
  • Debit Cards: Linked directly to your bank account, debit cards are used by most people around the world. Accepted everywhere, you will need to enter your card number, expiry date and security code information when you deposit though. Deposits and instant but withdrawals can take up to 3 working days due to banks’ processing times.
  • Apple Pay: Also available to use on mobile devices, Apple Pay has become very popular in recent years. Easily linked to your debit card, Apple Pay is widely accepted online and is eligible for casino bonus offers. Withdrawals are also free and fast.
  • Google Pay: Similarly to Apple Pay, this payment method is for Android users only. Increasingly more popular, you can link your debit card instantly as well as deposit and withdraw at a whole host of casino sites with ease. It’s also valid for welcome bonuses and has no fees associated.
  • Trustly: Most gambling sites now accept Trustly deposits and withdrawals. Available to use on mobile and tablet devices, Trustly connects to your bank account and offers fast, secure and free transactions.

Deposit Limit Restrictions

  • £40 per day
  • £240 per calendar month

When depositing at Pay by Phone Bill casinos in the UK, there are deposit limit restrictions you need to consider. The maximum you can deposit per day is £40 whilst the most you can deposit across a calendar month is £240.

With many casino bonuses offering match offers up to £100, you will not be able to claim to full bonus on offer if you use a Pay By Mobile method. Other options available such as PayPal and Apple Pay are better suited if you want to take advantage fully of a bigger casino offer.

Whilst the deposit amounts are added to your monthly mobile bill, Pay As You Go phone users will need to top up their account if they play regularly. For Pay As You Go users, it’s a good way to ensure you gamble responsibly and don’t overspend. If you’re on a contract, you may suddenly find yourself with a much bigger mobile bill the following month.

Pay By Phone Casinos Pros & Cons

With no withdrawals using Pay By Phone payment methods, this leads us nicely to the advantages and disadvantages of using this mobile payment option. Whilst there are lots of reasons to deposit at Pay By Phone bill casino sites, there are also downsides you need to consider:


  • No financial information is shared with the online casino

  • Easy and quick to use

  • Instant deposits

  • Secure and safe (SMS verification on every transaction)

  • Increasing number of casino sites offering Pay By Mobile options

  • Compatible with iOS and Android smartphones


  • Withdrawals or cashouts are not possible

  • Not as widely available as PayPal or debit cards

  • Not available to use with all mobile phone networks

  • Daily and monthly limit restrictions

How to Choose the Best Pay by Phone Casinos

If you’re happy using Pay By Mobile deposit methods, you also need to ensure the casino site is up to standards on other fronts. Below is a list of things to consider before deciding to play at a Pay by Phone casino:

  • Licensed by the UK Gambling Commission: All UK sites must be regulated and licensed by the Gambling Commission. This ensures fairness, that your information is secure, processes and standards are in place and responsible gambling tools are readily available. If you’re in Europe, look out for those licensed by the Malta Gaming Authority.
  • Wide Range of Payment Methods: Pay by Phone withdrawals are not possible so you need to be able to take out your winnings if you get lucky. Popular payment options like PayPal, debit cards, Apple Pay, Neteller and Skrill are the most common choices. Check how quickly they process withdrawals and if there are restrictions such as fees. Weekend cashouts are also a big plus.
  • Easy-to-use Site + Mobile Compatibility: Being able to navigate the casino site effortlessly is a must these days. This includes finding your favourite casino games, a clear My Account section, the ability to deposit and withdraw with ease and access to information is key to enjoying your experience. The site needs to be mobile and tablet-friendly with dedicated iOS and Android apps ideal.
  • Lots of Casino & Slot Games: The Pay by Phone casino needs to have a good selection of casino games including blackjack, roulette and live dealer options. Look for a wide range of slot games from reputable studios such as Pragmatic Play, NetEnt, Nolimit City and Play ‘n GO (amongst others).
  • Promotions & Offers: Having a welcome offer is ideal but there needs to be ongoing promotions and offers for existing customers. Make sure the offers have clear and transparent terms and conditions including details on eligible games, wagering requirements and restrictions. The best Pay by Phone casinos will offer weekly offers as well as cashback and slot tournaments.
  • Support & FAQs: Round-the-clock customer support via Live Chat is ideal but a comprehensive Help of FAQs section will suffice most of the time. Having support on hand is the goal with a UK telephone number and quick response times what you need to ensure any issues that may arise are dealt with promptly and efficiently.


Pay by Phone casinos are on the rise in the UK with more and more of us using our smartphones to play our favourite casino and slot games. Charging your deposit to your mobile phone bill or deducting from the Pay As You Go balance is very straightforward, quick and easy. However, you can only deposit up to £40 a day and £240 per month. The other major drawback is that you cannot withdraw using this method so another popular payment option is needed.
