Pay by Phone Bill Casinos: UK Best Sites 2025
The pay by phone bill casino method of depositing is convenient and fast. UK casino players can deposit at online casinos using just a mobile phone. Pay by Phone Bill casinos let you add funds to your casino account by charging the amount to your mobile phone bill (or deducting it from your pay-as-you-go credit).
Below we explore how Pay by Phone Bill works. We will also list the best Pay By Phone Bill Casinos, and explore the main providers (Boku, Payforit, Fonix), deposit limits, payment speed and more.
What is Pay by Phone Bill and How Does It Work?
Pay by Phone Bill (also called Pay by Mobile) lets you add casino deposits to your monthly phone bill. If you use a prepaid SIM, the network deducts the deposit straight from your airtime balance. This method is available to anyone with a UK mobile number on a major network.
Here’s how a typical Pay by Phone Bill deposit works at a UK online casino:
- Select Pay by Phone: In the casino’s cashier or deposit page, choose the “Pay by Phone Bill” option (it might appear as Boku, Payforit, or similar).
- Enter Your Mobile Number: Input the phone number linked to your device. Make sure you’re using a UK mobile provider that supports carrier billing (e.g. EE, O2, Vodafone, Three).
- Confirm via SMS/PIN: You’ll receive a text message with a confirmation code or PIN. Reply to the SMS or enter the PIN on the casino site to approve the payment.
- Deposit Processed: Once confirmed, the deposit is processed instantly.
- Charge to Bill or Credit: If you’re on a monthly contract, the deposited amount will be added to your next phone bill.
This easy process makes Pay by Phone Bill extremely quick and user-friendly. As long as you have a UK mobile (on networks like EE, O2, Vodafone, or Three), you can use this method in a few taps. It’s a popular choice for mobile casino players who value speed and simplicity.

Main Pay by Phone Bill Providers (Boku, Payforit, Fonix)
Several payment providers facilitate pay-by-phone transactions in the UK. They all serve the same purpose – charging casino deposits to your phone – but there are a few differences in branding and process. The main providers you’ll encounter are Boku, Payforit, and Fonix.
- Boku: Boku is one of the most widely used Pay by Phone Bill services globally. Boku is supported by all major UK networks (EE, O2, Vodafone, Three). Notably, Boku typically imposes a £30 daily deposit limit per user.
- Payforit: Payforit is essentially the framework developed by UK mobile operators to enable carrier billing. It’s backed by all major UK providers and acts as the platform through which the charges are routed.
- Fonix: Fonix is a UK-based mobile payments company that powers the “Pay by Mobile” or “Charge to Bill” solutions for many digital merchants, including casinos.
- Siru Mobile: Siru is only used by a couple of UK casinos for phone deposits (often with higher fees around 25–33% per transaction).
Deposit Limits, Transaction Speed, and Withdrawals
One key aspect of Pay by Phone Bill is that deposit amounts are capped at relatively low limits. This is both for regulatory reasons and to manage risk since the mobile operator is fronting the money until you pay your bill. Here’s what to expect in terms of limits and speed:
- Deposit Limits: Pay by Phone Bill deposits are typically limited to £30 per single transaction, with a hard daily cap around £30–£40 and a monthly cap around £240–£300.
- Transaction Speed: Depositing by phone bill is extremely fast. Once you confirm the SMS code, the transaction is processed in seconds, and funds show up in your casino balance right away.
- No Withdrawal to Phone: A major limitation of Pay by Phone Bill is that you cannot withdraw funds back to your phone.
- Multiple Deposits: Even with low per-transaction limits, you can make multiple phone bill deposits as long as you stay within the daily/monthly cap. For example, you might deposit £10 in the morning, £10 in the afternoon, and £10 in the evening – that would hit a £30 daily limit on some platforms.
Pay by Phone Bill Casinos is quick for deposits, but it’s intentionally limited in how much you can deposit and it does not support withdrawals. For many casual players, these limits are acceptable, even beneficial for budgeting. Just remember that you’ll need an alternative to cash out your winnings, and you can’t exceed the strict caps set by the carriers and casinos.
Advantages of Pay by Phone Bill Casinos
Paying by phone bill offers several unique advantages for online casino players, especially those who prioritize convenience and security:
- No Bank Card Needed: Perhaps the biggest benefit is that you don’t need a debit card, credit card, or bank account to deposit.
- Quick and Easy (Mobile-Friendly): Using your phone to deposit is extremely convenient. It’s a method designed for mobile users. You simply tap the pay-by-phone option and confirm via a text message. The user experience is very smooth, often just 2-3 steps.
- Secure and Verified: Carrier billing is a secure payment channel. Each deposit requires SMS verification or a PIN code, preventing unauthorized charges. Only someone with access to your physical mobile phone and SIM can approve a payment.
- Budget-Friendly (Low Limits): The small deposit limits can actually be an advantage for players who want to control their spending.
- No Extra Accounts or Apps: Unlike some payment options, you don’t need to sign up for any new service to use Pay by Phone. There’s no separate account creation (with Boku, for instance, you just use your phone number – no Boku account required).
- Eligible for Bonuses: In most cases, deposits made via phone bill still qualify for casino bonuses and promotions.
- Use Anytime, Anywhere: As long as you have your phone on you, you can deposit funds 24/7 from anywhere.
Pay by Phone Bill brings convenience, privacy, and control. Many UK players appreciate that it’s simple and doesn’t interrupt their gaming flow. You can add a tenner to your balance with just a text confirmation and keep playing securely.
Disadvantages of Pay by Phone Bill
While useful, Pay by Phone Bill casinos come with some downsides and limitations that players should be aware of:
- Low Deposit Limits: The flip side of low limits is that they can feel restrictive for some players. You typically cannot deposit more than £30 (or at most £40) in a day using this method.
- No Withdrawals to Phone: You cannot withdraw winnings back to your phone bill. For some players, this fragmentation is a drawback.
- Potential Fees: Phone companies themselves don’t charge you extra for using this service (your carrier simply adds the charge to your bill). But some online casinos apply a fee for Pay by Phone deposits.
- Limited Availability: Not every casino in the UK accepts phone bill payments.
- Can Encourage Impulse Deposits: While the low limits curb excessive spending, the sheer ease of depositing by phone could encourage frequent impulse deposits.
- Requires UK Mobile and Good Signal: This method essentially requires you to have a UK mobile number. Visitors or non-residents without a UK phone line generally can’t use this.
Pay by Phone Bill is superbly convenient for depositing small amounts, but it’s not a comprehensive banking solution for gambling. It works best as a supplemental method or for those who only gamble casually.
UKGC Regulations and Responsible Gambling Considerations
Pay by Phone Bill transactions at UK casinos fall under the purview of several regulatory bodies and rules. These bodies aim to enforce responsible gambling.
- Classification as E-Money: The UK Payment Services Regulations (PSR 2017) classifies “charge to mobile” payments as electronic money.
- UKGC Licensing: Casinos must hold a UK Gambling Commission licence before they can offer Pay by Phone Bill to UK players.
- Carrier and PSA Oversight: The Phone-paid Services Authority (PSA) partners with mobile networks to supervise the Payforit platform and all carrier-billing activity.
Pay By Phone Bill KYC and Verification
Verification and KYC: UK casinos will require you to verify your identity at some stage (usually before your first withdrawal or if you deposit a certain total amount). The UKGC do this to prevent fraud and underage gambling.
