Pay by Phone Casinos UK 2026: The Complete Guide
Pay by phone casino deposits have never been the default for UK players. They exist, they work, and a handful of mobile-first operators have built entire products around them. But the method is quieter than a responsible gambling pop-up. If you are looking for a way to fund a casino account without typing card details, this is the 2026 state of play.
Most high-street brands still ignore phone bill deposits. The credit card ban from 2020 did not kill pay by phone, but it did not make it mainstream either. What remains is a niche cluster of UK Gambling Commission licensees that accept Boku, Payforit, and occasionally Siru Mobile. The trade-off is clear: convenience and low limits versus a deposit method that cannot handle withdrawals.
This guide covers how carrier billing actually works at UK casinos, which brands still accept it in 2026, the fees and deposit limits you should expect, and why the phrase ‘not on GamStop’ in the same sentence as pay by phone should make you leave the page.
What Pay by Phone Actually Means in 2026
Paying by phone at a casino is not the same as tapping Apple Pay or Google Pay in a shop. The phrase refers to a deposit charged to your mobile phone bill, or deducted from your prepaid credit, using a carrier billing provider. The two dominant names in the UK are Boku and Payforit. Siru Mobile appears occasionally, but it has never gained much traction outside a few niche brands.
The process is deliberately simple. You pick ‘pay by phone’ or ‘mobile billing’ on the casino cashier, enter your mobile number, and confirm the payment with a text message or one-time code. The amount is then added to your next phone bill if you are on a monthly contract, or taken from your available credit if you are on pay-as-you-go. No card number, no bank login, no e-wallet password.
But the word ‘simple’ does a lot of heavy lifting. The deposit still lands in a verified casino account, not a black box. You must have passed age and ID checks before the casino allows any deposit method, including phone billing. What you gain is a frictionless top-up. What you lose is any chance of withdrawing that money back the same way.
How Deposits Work: Boku, Payforit, and Carrier Billing
Boku dominates the UK market for gambling-related carrier billing. Its integrations appear at mFortune, PocketWin, Mr Spin, and several sibling brands. Payforit works in a similar way but has stricter merchant categories, which is why some casinos offer one and not the other. Both rely on the mobile network operator to authorise the charge and add it to your bill. That means your network, not the casino, often sets the upper deposit limit.
Deposit limits for pay by phone are lower than almost every other method. A VIP player who wants to move £500 in one go will not use Boku. The typical daily cap is set by the network and the casino together, and it rarely stretches beyond a modest amount. For a £5 or £10 session on mobile slots, that is fine. For anything larger, you need a debit card or bank transfer.
Fees are another area where the details matter. Most UK pay by phone casinos do not add a surcharge, and the network does not charge the player either. But always check the cashier before confirming. Some operators quietly pass on a small processing cost, especially for deposits under £10. If a fee appears, it is not a technical glitch; it is a business decision, and you should treat it as a reason to reconsider the casino.
- Boku – most common, works on all major UK networks, charged to phone bill or prepaid credit.
- Payforit – similar carrier billing, sometimes limited to certain networks, used by older mobile casino brands.
- Siru Mobile – occasional alternative, less widely accepted at UK-licensed sites.
Top Pay by Phone Casinos Compared
The table below lists the UK-licensed casino brands that actively advertised pay by phone deposits as of early 2026. These are not the biggest names in the industry, but they have held UKGC licences and maintained working Boku or Payforit integrations for years. Bonus columns show only the type of offer, not a specific amount, because promotional terms change too often for static figures to be useful.
| Casino | Pay by phone method | Bonus type | Notes |
|---|---|---|---|
| mFortune Casino | Boku, Payforit | Welcome bonus | UKGC licensed; no withdrawal to phone bill |
| PocketWin Casino | Boku, Payforit | Free spins | Mobile-first interface; frequent small offers |
| Mr Spin Casino | Boku | No deposit free spins | Slots-only brand; low minimum deposit |
| Cashmo Casino | Boku | Welcome bonus | Low-stakes slots; Boku only |
| Dr Slot Casino | Boku, Payforit | Free spins | Slot-focused catalogue; simple lobby |
| Jammy Monkey Casino | Boku | Welcome bonus | UKGC licensed; fast registration |
| Pocket Fruity Casino | Boku, Payforit | No deposit free spins | Retro slots focus; pay by phone long-standing |
| Spinzaar Casino | Boku | Welcome bonus | Newer mobile casino; few payment options |
| Casino 2020 | Boku, Payforit | Free spins | Simple mobile lobby; Boku as primary method |
Selection criteria: the casino must hold a current UK Gambling Commission licence, offer at least one pay by phone method for deposits, and not be flagged for unresolved payment complaints on major UK player forums. The brands above are the core group that has remained stable across 2024 and 2025.
A second table is not needed to understand the method itself, but if you are comparing Boku and Payforit, the difference is mostly one of availability. Boku tends to support all four major networks—EE, Vodafone, O2, Three—while Payforit occasionally drops one network due to commercial agreements. That nuance rarely appears in casino reviews, which is why many players end up confused when a deposit fails on one network but works on another.
Deposit Limits, Fees, and Withdrawal Realities
Pay by phone deposits are asymmetric by design. The casino can take money from your phone in seconds, but the casino will not send winnings back to your phone bill. Withdrawals always go to a bank account, debit card, or e-wallet that has passed the casino’s verification checks. That means you cannot use pay by phone as a closed loop. You deposit with your phone, you withdraw with your bank.

This asymmetry catches new players. You might deposit £10 via Boku and win £50. When you request a withdrawal, the cashier will ask for a bank account or PayPal. If you have never verified one, you are stuck until you do. It is not a scam, but it is an extra step that most card depositors never face. The phone bill deposit is only one half of the transaction.
Daily and monthly limits also matter. UK operators often cap carrier billing deposits lower than £50 per day, and the network may impose its own lower cap. If you try to deposit twice in 24 hours, the second attempt can fail without explanation. That is not the casino blocking you; it is the mobile network applying its own anti-fraud rules. For a player who wants a quick £5 on Starburst, this is irrelevant. For anyone doing serious session budgeting, it is a persistent annoyance.
Licensing, Safety, and the GamStop Question
Every legitimate pay by phone casino in the UK holds a licence from the Gambling Commission. That is not negotiable. The licence covers all deposit methods, including carrier billing. If a site claims to offer pay by phone but appears on the Commission’s list of unlicensed operators, avoid it. No amount of Boku branding makes an offshore site safe.
The same logic applies to GamStop. A UKGC-licensed casino must integrate with GamStop self-exclusion. Pay by phone deposits do not create a loophole. If you self-exclude via GamStop, the casino must block your account and reject further deposits, including phone bill deposits. Sites that advertise ‘pay by phone not on GamStop’ are explicitly targeting players who want to bypass a responsible gambling tool. That should be a red flag, not a selling point.
There is a persistent myth that phone bill deposits are anonymous. They are not. The casino still knows your name, address, date of birth, and mobile number. The mobile network knows exactly when and where you paid. The bank or network bill shows a line item, usually under the processor name such as ‘Boku’ or ‘Payforit’, not the casino brand. That is a small privacy benefit, but it does not make the transaction invisible. If anonymity is your goal, pay by phone is the wrong method.
Bonuses and Wagering: The Fine Print
Most pay by phone casino bonuses are identical to regular bonuses, just smaller. The reason is structural: deposit limits are low, so a 100% match on a £10 deposit is worth £10, not £500. Free spins offers tend to be the dominant promotion because they fit neatly into a £10 or £20 phone deposit. No-deposit free spins also appear, but they are usually capped at 10 or 20 spins and come with maximum win limits.
Wagering requirements still apply. If a bonus claims to be ‘free’, remember that the casino is not a charity. The word ‘free’ appears because it attracts attention, not because the money is genuinely free. Read the terms: playthrough on the bonus, game weighting, expiry dates, and maximum bet limits. A free spin worth 10p can carry a 35x playthrough that is mathematically impossible to clear on a limited game selection. That is not a flaw; it is the design.
One genuine advantage of pay by phone casinos is that they often run lower-stakes promotions. You will see more £5 deposit bonuses and fewer £1,000 match offers. For a casual player, that is better value, because the wagering is easier to meet in absolute terms. But it is still a bonus. Treat it as a small discount on your entertainment, not as income.
FAQ
These are the questions that appear again and again on UK casino forums, answered without the marketing gloss.
Payforit Mobile Casinos UK 2026: Pay by Phone Bill at Licensed Casino Sites
Can I deposit at UK casinos using my phone bill?
Yes, but only at a specific group of UK-licensed casinos that integrate Boku or Payforit. You choose pay by phone in the cashier, enter your mobile number, and confirm by text. The deposit is added to your phone bill or deducted from prepaid credit. It is not available at every casino.
Are pay by phone casino deposits legal in the UK?
Pay by phone deposits are legal in the UK as long as the casino holds a Gambling Commission licence. The method itself does not breach any regulation. The credit card ban of 2020 did not affect carrier billing, because the charge is collected by the mobile network, not a credit provider.
Which mobile networks support pay by phone casino deposits?
Boku and Payforit work on EE, Vodafone, O2, and Three, though individual casinos may not support every network. Some smaller networks and MVNOs are excluded. Always check the casino cashier or support page before trying to deposit, because network availability can change without notice.
Can I withdraw winnings back to my phone bill?
No. Pay by phone is a deposit-only method in the UK. Withdrawals must go to a verified bank account, debit card, or e-wallet. This is the biggest drawback of carrier billing. You can fund your account in seconds, but you cannot receive money back through the same channel.
Are pay by phone casinos safe if they are not on GamStop?
No. A UKGC-licensed casino must be part of GamStop, regardless of deposit method. Any site advertising ‘pay by phone not on GamStop’ is either unlicensed or operating outside the UK framework. Avoid it. The whole point of GamStop is to block access when you need it, and no deposit method overrides that.
