The UK Gambling Commission (UKGC) licenses every pay-by-phone casino UK players can lawfully use, and it binds those operators to the same Licence Conditions and Codes of Practice (LCCP) and Remote Gambling and Software Technical Standards (RTS) as any other UK online casino. And since 31 October 2025, those rules include a mandatory deposit-limit prompt before any new customer's first deposit.
Two carrier-billing providers fund the pay-by-phone deposits this page covers. Boku Network Services UK Limited applies the per-deposit caps at the carrier layer, and its FCA-authorised arm, Boku Account Services UK Limited (FRN 900030), is the regulated entity that clears the money. Fonix Mobile plc (LSE:FNX) is the second provider, used by operators such as MrQ and Hot Streak Casino. Both run on direct carrier billing, the mechanism that charges a deposit to your mobile bill rather than a card.
Here's the part most sites miss. The £30 daily and £240 monthly caps that Boku has applied to UK casino deposits for over a decade are, in effect, a built-in deposit limit, the same control type the 31 October 2025 UKGC deposit-limit mandate has now made standard across every UK online operator. This page covers the UKGC rules that bind pay-by-phone deposits, how GamStop behaves at Boku and Fonix operators, the support services every licensed operator must reference, and how to report an unlicensed site. It doesn't duplicate the wider UK regulatory roadmap or run operator-by-operator licence checks, because both live elsewhere on the site.
UKGC rules for pay-by-phone casinos
Pay-by-phone casinos in the UK are regulated by the UK Gambling Commission (UKGC) under the Licence Conditions and Codes of Practice (LCCP) and the Remote Gambling and Software Technical Standards (RTS). Since 31 October 2025, every UKGC-licensed online operator, including those that accept Boku or Fonix carrier-billed deposits, must prompt new customers to set a financial limit before their first deposit and remind them to review it every six months.
There's no carve-out for carrier billing. A casino that takes a Boku or Fonix deposit follows exactly the same LCCP rules as one that takes a debit card, because the licence sits on the operator, not on the payment method, a status you can confirm on the UKGC public register. So the licence binds the operator's conduct, its complaints handling, its fairness obligations, and its responsible-gambling tools, no matter how a deposit reaches the account.
The same goes for anti-money-laundering duties. UKGC-licensed operators have to run source-of-funds and identity checks, monitor transactions, and apply enhanced scrutiny once a customer's spend crosses risk thresholds, and a phone-billed deposit is watched the same way as a card one. Carrier billing doesn't sit outside the AML framework.
The headline change is the RTS 12 update that took effect on 31 October 2025. It's a binding rule, not guidance: operators must show new customers a deposit-limit prompt at the first-deposit stage (RTS 12) and send a review reminder every six months. A further rule landing on 30 June 2026 tightens the terminology operators must use for these limits. For the full timetable, see the UK gambling regulation roadmap 2026.
How the £30/day Boku cap functions as a deposit limit
Boku Network Services UK Limited has applied the same £8 first-deposit, £30 daily, and £240 monthly caps to UK gambling deposits since well before the UKGC's 31 October 2025 mandate. In practice, that means pay-by-phone deposits have been delivering the deposit-limit control type the regulator has now standardised, for over a decade, and at the carrier layer where you can't quietly opt out.
The numbers are worth stating precisely. Boku caps a UK gambling deposit at £8 on the first transaction, then £30 a day and £240 a month, a regime that sits below the UKGC's own RTS 12 financial-limits rule. Fonix and Siru carrier billing sit at a higher £40 daily ceiling, with the same £240 monthly figure, so the daily ceiling depends on which provider clears the deposit.
And the cap is set at the carrier-PSP layer, which is the detail that makes it bite. It binds across every UKGC-licensed operator you use with the same mobile number, so opening a second casino account doesn't unlock a second allowance. Where the FCA-authorisation anchor matters, the regulated entity is Boku Account Services UK Limited (FRN 900030); Boku Network Services UK Limited is the related trading entity that applies the caps, not the FCA-authorised arm.
So the cap reads best as a structural responsible-gambling feature, not a carrier-billing quirk. When the 31 October 2025 mandate landed, card-deposit casinos had to build new prompts and friction into their first-deposit flow. Pay-by-phone deposits already sat inside a hard-capped envelope. The £30 daily cap functions like a regulated deposit limit even though it isn't technically labelled one under the new RTS terminology rule arriving on 30 June 2026, a nuance covered in the UK gambling regulation roadmap 2026. For the mechanics of the deposit itself, see how pay-by-phone deposits work.
GamStop and pay-by-phone casinos
Every UKGC-licensed online operator has to integrate with GAMSTOP, the UK's national online self-exclusion scheme. Once you're registered with GamStop, the scheme blocks your account access, and therefore any Boku or Fonix deposit attempt, at every UKGC-licensed gambling site and app for the exclusion period you chose.
GamStop works at the account level, on the operator side. The block sits on your account, which is why a Boku-funded deposit can't reach a GamStop-registered account: the login is refused before the cashier ever loads. And it isn't the mobile number used for billing that triggers the block, it's the registered account credentials, so switching deposit method changes nothing.
You pick the exclusion period, either 6 months, 1 year, or 5 years, and it can't be reversed during the window you select. That permanence is the point. One registration covers every licensed operator at once, so there's no need to self-exclude site by site.
But one scope limit matters. GamStop covers UKGC-licensed sites only, so don't assume it catches non-UKGC offshore sites. Those sites are off-limits to UK players because they're unlicensed, not because GamStop blocks them, and no GamStop workaround exists at a licensed operator. So if a site is taking phone-bill deposits while sitting outside UKGC licensing, the route to deal with it is to report it, which the section below walks through.
Self-exclusion mechanisms at UKGC casinos
Every UKGC-licensed pay-by-phone casino has to offer its own account-level self-exclusion and time-out tools, on top of GamStop's cross-operator scheme. These sit underneath GamStop as the operator-side layer, and they run from short cool-offs to long self-exclusions.
The tools come in three tiers. A time-out is a short cool-off, typically 24 hours up to 6 weeks, that pauses the account without closing it. A deposit limit is the LCCP-mandated financial control set under the RTS 12 wording. And self-exclusion runs for a minimum of 6 months under LCCP, applied at that single operator.
The 31 October 2025 deposit-limit prompt runs before your first deposit, so you're offered a deposit-limit control at the earliest possible point in the journey. Operators also offer reality-check intervals under LCCP, usually configurable from 15 minutes upwards, which pause play to show how long a session has run. And the operator cards on the pay-by-mobile casinos UK guide catalogue the exact RG tools at each of the four live pay-by-phone operators, Casushi, MrQ, Hot Streak Casino, and Mr Vegas.
GamCare and GambleAware support resources
Two UK charities provide the front-line support that UKGC operators are required to reference: GamCare, which runs the National Gambling Helpline on Freephone 0808 8020 133 (24 hours, 7 days), and GambleAware (formerly BeGambleAware), the commissioning charity behind the National Gambling Treatment Service.
GamCare runs the helpline around the clock, free to call, and offers a live web-chat alternative if you'd rather not phone. The charity also coordinates the National Gambling Treatment Service, which routes people to structured support beyond that first call.
GambleAware commissions the wider treatment network and runs a free advice site. It rebranded from BeGambleAware, and operator footers still often carry the old brand, but both URLs route to the same charity. Gamblers Anonymous (UK) is the third recognised resource, a peer-support network for anyone who wants a group setting.
And every UKGC-licensed pay-by-phone casino must display GamCare or GambleAware contact details in its footer under the LCCP social-responsibility code. These services cover phone-bill players exactly as they cover any other UK gambler.
Reporting an unlicensed pay-by-phone casino
If a casino is taking pay-by-phone deposits from UK players without an active UKGC licence, the regulator wants to know. Reports go straight to the Gambling Commission, ideally with the operator's URL, screenshots, and any deposit-transaction evidence you have.
Four steps cover it. First, verify the operator's licence status on the UKGC public register, searching by operator name or licence number, where an active licence shows a status of "Active" and a surrendered, lapsed, or suspended status isn't lawful for new UK custom. Second, capture evidence: the operator's URL, any licence number it displays in its own footer, screenshots of the deposit page, and a record of any deposit attempt. Third, submit a report through the Gambling Commission's reporting routes on its website. Fourth, if you've already deposited, contact your mobile carrier for the Boku or Fonix-billed charge and the bank behind the carrier account, because the operator may not honour a withdrawal and the carrier can sometimes reverse the charge as a billing dispute.
The In Touch Games Limited case shows you exactly what a "stopped operating" entry looks like. The Commission suspended the operator's licence in 2023, and In Touch Games Limited surrendered the licence on 5 September 2023. It ran mFortune, PocketWin, and Mr Spin, so all three brands stopped being lawful UK pay-by-phone destinations from that date, and they stay excluded from any recommendation on this site. The public-register entry, business detail 2091, carries the status change on the Commission's own record, alongside its regulatory-sanctions log. That's the exact check this page asks you to run before depositing anywhere.
UKGC and responsible gambling FAQ
- Are pay-by-phone casinos regulated in the UK?
- Yes. Every UK-facing pay-by-phone casino must hold an active UK Gambling Commission remote-gambling operating licence and follow the same LCCP rules as any other UK online casino, including the 31 October 2025 deposit-limit prompt mandate.
- Does GamStop block pay-by-phone deposits?
- Yes. GamStop is an account-level block, so once you're registered, the operator must refuse any login attempt, which stops the Boku or Fonix deposit page being reached in the first place.
- Is the £30/day Boku cap a UKGC rule?
- No. The £30 daily and £240 monthly caps are set by Boku and the UK mobile carriers at the PSP layer. They predate the 31 October 2025 UKGC deposit-limit mandate by more than a decade, and they function as a built-in deposit limit even though they aren't the UKGC's own rule.
- How do I check if a pay-by-phone casino is UKGC-licensed?
- Search the operator's name or licence number on the UKGC public register at gamblingcommission.gov.uk/public-register. An active licence shows status “Active”. If the entry says “Lapsed” or “Surrendered”, the operator isn't lawful for UK custom.
- What support is available if my gambling becomes a problem?
- Call the National Gambling Helpline on 0808 8020 133 (GamCare, 24 hours a day). GambleAware (formerly BeGambleAware) commissions the wider National Gambling Treatment Service and runs a free advice site.
- Can mFortune, PocketWin or Mr Spin still take pay-by-phone deposits from UK players?
- No. Their operator, In Touch Games Limited, surrendered its UK operating licence on 5 September 2023. None of the three brands is licensed to take real-money deposits from UK players from that date onwards.
