Pay By Phone Casino UK: Deposit With Your Mobile Bill in 2026

Smartphone displaying mobile billing payment interface for pay by phone casino deposits

Pay by phone casino deposits let you add money to a casino account and have the charge show up on your monthly mobile bill or come straight off pay-as-you-go credit, no card or bank login required. UK-licensed casinos run this through one of three active providers. Boku, Fonix and Siru currently handle it. Type in your number, confirm on your phone, and the balance lands in seconds.

None of it comes back the same way.

Phone-bill billing has no payout leg at all. Win money depositing through Boku and you’ll still withdraw it to a bank account, debit card or e-wallet.

Casinos That Currently Take Pay By Phone Bill

Our casino database tracks payment methods across dozens of operators, and right now it holds confirmed tags for 46 casinos on Apple Pay and 32 on Google Pay. Carrier billing, Boku, Fonix and Siru together, doesn’t have a comparable number of confirmed listings. Operators change cashier options often, several UK sites that showed phone billing a year ago have since dropped it, and self-reported “we accept Boku” claims on comparison sites are wrong often enough that publication would be unreliable.

Our Boku casinos page covers that single provider. If a casino’s cashier shows a phone icon or the words “pay by mobile,” confirm the provider name on the payment screen itself before you commit to a deposit amount. That screen is the only place the current terms actually live.

New Casinos Adding This Method

Carrier billing isn’t a growth category among UK operators right now. Open banking rails like Trustly and card-linked wallets like Apple Pay have taken most of the cashier real estate that phone billing used to hold, because they support a withdrawal path.

New casinos may add Boku, Fonix or Siru this year. Check our payment methods hub for the current picture across every rail we track, and check the cashier of any specific casino you’re considering.

Why Trust This Guide

I’m Eva de Jong, Banking & Payments Editor at YummySpins. Deposit and withdrawal mechanics are the part of a casino review most sites skim, and it’s the part that actually decides whether your money moves when you want it to.

For this page, that meant reading the Gambling Commission’s published guidance line by line and checking Boku’s and Fonix’s own merchant documentation for how carrier billing actually works. The top-ranking pages for this exact search were blocked from direct review by anti-bot protection during research, so this page follows YummySpins’ standard payment-method structure on its own terms. The Commission’s published credit-card guidance does not mention carrier billing by name.

What Pay By Phone Billing Actually Is

Carrier billing charges a purchase to your phone account. On a monthly contract, the deposit shows up as a line item on your next bill. On pay-as-you-go, it comes straight off whatever credit you have loaded. The casino never sees a card number or a bank account.

Three providers run this in the UK gambling market. Boku, Fonix and Siru are the ones active today. Boku has the widest network reach, covering EE, O2, Vodafone and most other UK carriers. Pay-as-you-go SIMs sometimes see lower limits or get excluded outright. Fonix covers Vodafone, EE, Three, BT Mobile and O2. Siru works the same basic way as the other two. It can add a small percentage fee, folded straight into the bill itself.

You’ll still see the older PayForIt brand mentioned on comparison sites and in casino terms pages that haven’t been updated. PayForIt has been wound down as an active service, and regulatory oversight of premium-rate and carrier billing moved from the Phone-paid Services Authority to Ofcom on 1 February 2025. A casino’s terms that still name PayForIt specifically are running on old copy left over from before that switch.

Zimpler shows up in searches for “mobile payment casino” because it’s fast and phone-based, but it’s a bank-based Pay by Bank method. It pulls from your actual bank account through a single authentication step and can pay winnings straight back.

Three providers actually run UK phone-bill casino deposits in 2026, and every one of them stops at the deposit.

Mobile App Support

You won’t find a dedicated app for phone-bill casino deposits, and that’s not really a gap. Most UK-facing casinos rely on a mobile-optimised website. A dedicated app is the exception, partly because Apple and Google both restrict standalone real-money gambling apps across large parts of their stores. Where a casino does offer an app, it’s usually a wrapper around the same site you’d reach through Safari or Chrome.

Depositing by phone bill needs nothing beyond that mobile browser. You open the cashier, tap the phone-billing option, and confirm through an SMS or on-screen prompt sent to the same device. There’s no separate Boku or Fonix app to install. The provider works invisibly behind whichever casino site you’re already using, and the phone-billing flow inside a casino’s own app, where one exists, works identically to the browser version.

Pros

  • No card number or bank login ever touches the casino
  • Works on pay-as-you-go with no bank account at all
  • Deposits clear in seconds through Boku, Fonix or Siru
  • Low per-transaction caps double as a built-in spending limit
  • Confirmation step (SMS or on-screen prompt) adds a layer contactless cards don’t have

Cons

  • No payout leg whatsoever, winnings go elsewhere
  • Per-transaction limits are low, sometimes as little as £10
  • Siru can tack on a percentage fee
  • Far fewer UK casinos support it than support cards or e-wallets
  • Some welcome bonuses exclude phone-bill deposits from eligibility
  • A charge buried in your monthly bill is easy to lose track of if you’re not checking statements

How to Deposit With Pay By Phone Bill

Phone showing mobile signal icon for pay by phone casino deposit
A pay-by-phone deposit confirms through your phone’s mobile signal, not a card.
  1. Open the cashier at a UK-licensed casino and select Pay by Mobile, or the specific provider (Boku, Fonix or Siru) if it’s named directly.
  2. Enter your mobile number. No card details, no sort code.
  3. Choose your deposit amount, staying inside whatever limit the cashier displays.
  4. Confirm via SMS or the on-screen prompt sent to your phone.
  5. The deposit lands in your casino balance, typically within seconds of confirming.

Most players skip reading the confirmation limit shown on screen before tapping through. That figure, shown at the moment you deposit, is what actually applies to your account, regardless of anything published elsewhere.

How to Withdraw Winnings

Winnings routed to bank card or e-wallet, not phone bill
Winnings always route to a bank card, bank transfer or e-wallet, never back to a phone bill.

Carrier billing moves money in one direction only, so you cannot withdraw back to Boku, Fonix or Siru.

When you win, the casino needs somewhere else to send it. That’s almost always a debit card, a bank transfer, or an e-wallet if the casino supports one. You’ll typically go through identity verification the first time you cash out, standard practice at any licensed UK operator regardless of how you funded the account. The payout lands on whichever method you’ve added and verified. That’s never the phone number you deposited with. Set up your withdrawal method before you deposit by phone, ideally the same day you make your first deposit. Do it once, before you win, and cashing out afterwards is straightforward. If you’d rather deposit and withdraw through the same channel from the start, our Trustly casinos page covers a bank-based rail that handles both directions, and our fast payout casinos guide covers which UK operators clear withdrawals quickest once you’re set up.

Bonuses for Pay By Phone Deposits

Welcome offers don’t discriminate by rail as a rule. A casino running a deposit-match promotion generally honours it whether you funded the account by card, e-wallet or phone bill. What does vary is the deposit minimum required to trigger the bonus, since phone-billing caps are lower than most other methods and a £10 deposit might sit under a casino’s £20 bonus threshold.

Some operators exclude phone-bill deposits from bonus eligibility outright, usually buried in the small print under payment method restrictions. Check the bonus terms before you deposit if claiming an offer is the point of the exercise. Finding out afterwards, once the balance already reflects a deposit that didn’t qualify, is a worse way to learn it.

Games You Can Play After Depositing

Phone-bill billing doesn’t restrict which games your money can touch. Once the deposit clears, it sits in your casino balance the same way a card deposit would, playable across slots, live dealer tables, and everything else the operator offers.

You’ll find the same catalogue you’d see funding any other way. Slot libraries are built around studios like Pragmatic Play, NetEnt and Play’n GO, and live tables are run by providers such as Evolution. Nothing about the payment method itself locks you out of a game category. Wagering requirements on a specific bonus might restrict things. That’s a bonus-terms question, separate from the payment method itself.

Is Pay By Phone Safe for Casino Deposits, and What About the Credit Card Ban?

Start with the licence. A UK Gambling Commission licence is what actually protects you here, and a phone-billing option sitting in the cashier doesn’t add or subtract from that. Once a licence is confirmed, carrier billing carries its own real security features. No card number ever reaches the casino, the deposit needs an SMS or on-screen confirmation you control, and low transaction caps limit how much a single mistake or a stolen phone can cost you.

The Commission’s credit card gambling ban, in force since 14 April 2020, covers remote and non-remote gambling broadly and extends to e-wallets where the wallet itself is funded by a credit card. Phone-bill billing falls into a grey area here. I’ve read through the Commission’s published credit-card guidance and its operator rules on preventing credit-card use, and neither one mentions phone-bill or carrier billing directly. A postpaid mobile bill is a form of deferred payment in substance. The Commission hasn’t issued guidance stating whether phone-bill deposits fall inside or outside the ban’s intent. UK-licensed casinos have continued offering Boku, Fonix and Siru since 2020, which suggests operators read it as outside the ban’s scope. If certainty matters to you here, ask the operator directly.

Beyond licensing, GAMSTOP remains the UK’s national self-exclusion scheme, and every licensed operator must participate regardless of which payment methods sit in its cashier. If gambling stops feeling like entertainment, that’s the signal to use it. Support is also available through BeGambleAware, and none of what’s on this page is intended for anyone under 18.

Pay By Phone Casino: Key Facts

None of the figures below are set by a regulator, and the cashier screen in front of you always wins over anything printed here.

Providers don’t publish a single dated rate card for limits, networks apply their own caps on top, and casinos can set stricter limits than either. The cashier screen in front of you, at the moment you deposit, is the only source that’s actually authoritative for your account.

Alternative Payment Methods to Consider

If the missing payout leg is a dealbreaker, a few other rails solve it directly. Trustly casinos connect straight to your bank account for both deposits and withdrawals, with no card needed either direction. PayPal casinos offer a widely supported e-wallet route that most UK operators can pay out to, provided your PayPal balance itself isn’t funded by a credit card. If privacy without a bank login is the priority and a payout route still matters, our Boku casinos page walks through which operators pair carrier billing with a workable second method for cashing out.

Frequently Asked Questions

How do I deposit using pay by phone at UK casinos?

Open the casino’s cashier, select Pay by Mobile or the specific provider (Boku, Fonix or Siru), enter your mobile number, choose an amount within the displayed limit, and confirm via the SMS or on-screen prompt sent to your phone. The deposit typically lands within seconds.

Which UK online casinos accept pay by phone (Boku/PayForIt-style) payments?

PayForIt itself has been wound down; Boku, Fonix and Siru are the active carrier-billing providers in 2026. Our casino database doesn’t yet hold a confirmed, verified list of operators tagged with carrier billing, so check our Boku casinos page and confirm the provider name on the cashier screen itself before depositing.

Is pay by phone safe for casino deposits?

Yes, provided the casino holds a UK Gambling Commission licence, which is the protection that actually matters. Carrier billing adds its own layer on top. No card number reaches the casino, every deposit needs an SMS or on-screen confirmation, and per-transaction caps limit how much a single mistake can cost.

What are the deposit limits for pay by phone casino payments in the UK?

Limits vary by provider, network and casino. You’ll typically see roughly £10 to £30 per transaction, with daily caps commonly around £30 and reported as high as roughly £90 on some networks. These aren’t regulator-set figures. The cashier screen at the moment you deposit is the authoritative number for your account.

Can I withdraw winnings using the same pay-by-phone method?

No. Carrier billing has no payout leg at all, so Boku, Fonix and Siru can take a deposit but never return one. Winnings go to a bank transfer, debit card or e-wallet instead, so it’s worth setting up one of those before you deposit. Sort it out ahead of a win and cashing out afterwards is simple.
