A mobile casino not on GamStop is an operator with no Great Britain licence, so it is not connected to the national self-exclusion scheme. Its deposits go through the same phone or app, but the protection does not. A GamStop exclusion holds for its full term and then stays in place until Gamstop Online is contacted to remove it.
I have spent years reading licence conditions for a living, and the phrase "not on GamStop" is the most oversold selling point in this market. It sounds like a doorway. It is really a description of an absence: a site that has not asked the Gambling Commission for permission to trade here, and therefore has not signed up to the one scheme that would stop it accepting a self-excluded player. The words say nothing about the games, the odds, the payout or the willingness to hand over a balance.
Here is the thing that gets lost. Self-exclusion is not a six-month cooling-off period that expires quietly. Since 31 March 2020 every operator holding a Gambling Commission licence must be part of Gamstop as a condition of that licence, under social responsibility code provision 3.5.5 of the Licence Conditions and Codes of Practice. Once a registration is in, it cannot be cancelled mid-term. When the chosen term ends, it simply carries on until the person contacts Gamstop to remove it. Operators licensed in Great Britain must also check their entire customer base at least every 24 hours, a requirement the Commission introduced in April 2020, which is what makes a block hard to slip past at an onshore site.
None of that reaches an offshore brand. The Gambling Commission states plainly that it is illegal for anyone to offer commercial gambling services to consumers in Great Britain without a Commission licence, including where the operator holds a licence in another country. The Commission is a regulator, not an ombudsman, and it cannot chase a balance on anyone's behalf. The scale is not trivial: the Commission's remit only covers sites that trade or advertise here, and its estimate of time spent on illegal sites by GB consumers was 152 million minutes in July 2025. Meanwhile, among people who had gambled online in the past four weeks, the Commission estimates 2.5 per cent had engaged with an illegal site.
If gambling is causing harm, the help is free and immediate. The National Gambling Helpline, run by GamCare, is on 0808 8020 133, 24 hours a day, every day; callers in Wales can also use 0808 2819 265. Blocking software such as Gamban and BetBlocker adds a layer that a phone bill cannot provide. And the term itself, once set, holds.

What Pay by Mobile Changes, and What It Does Not
The cluster that brings most people here is the pay-by-mobile question. So: a pay-by-mobile casino not on GamStop is an offshore site that lets a deposit be charged to a mobile phone bill, a call credit or an e-wallet, and it sits outside the self-exclusion scheme for the same reason as any other unlicensed operator. The payment rail is different. The regulatory position is identical.
That matters because pay-by-mobile carries an emotional colour the other deposit methods do not. A card deposit feels like a bank transaction: there is a statement, a name, a fraud line at the other end. A phone-bill charge of £10 feels like nothing at all. For anyone with a self-exclusion in place, "nothing at all" is precisely the problem. There is no onshore equivalent, because onshore operators cannot use a payment method that is not provided by a payment service provider within the Payment Services Regulations 2017 — a condition attached to licence condition 5.1.2 and effective since 31 January 2024.
The mechanics are also worth stating because they are so often blurred. Phone-bill and SMS billing work through carrier billing, and the sums involved are small by design: a carrier will not let a merchant run up a phone bill the way a debit card can be run up. The result is a deposit method that looks tidy at £10 a go and adds up over an evening. A mobile deposit casino not on GamStop tends to advertise the smallness as a virtue. It is not a limit; it is a unit of measurement.
Then there is the licence in the footer. Curaçao, Anjouan, Kahnawà:ke and Costa Rica all get waved about as though each were a regulator in the British sense. They are not the same thing. A Curaçao licence costs a one-time non-refundable application fee of EUR 4,592 and an annual total of EUR 47,450; an Anjouan B2C licence is EUR 17,828 a year with EUR 500 per additional domain; the Kahnawà:ke Commission's client provider application fee is rising from USD 35,000 to USD 40,000 on 1 January 2027. Those are fees. Fees are not supervision, and none of those authorities has any power over what happens to a balance held by a British customer.
Where the licence comes from, and what each one actually promises
| Licence authority | Cost of holding it | What a British player can do about a complaint | Self-exclusion link |
|---|---|---|---|
| Gambling Commission (GB) | Not a fee-based comparison; licence conditions apply, funded by a statutory levy of 1.1% of online gross gambling yield | Refer to an approved ADR provider free of charge after eight weeks | Must be part of Gamstop as licensing condition 3.5.5 |
| Curaçao (LOK) | EUR 4,592 application plus EUR 47,450 total annual | Operator must designate an authority-approved dispute route | No Gamstop obligation |
| Anjouan | EUR 17,828 a year, EUR 500 per extra domain | Approved ADR providers include EGIS ADR, Axion ADR, iGaming ADR and one service provider; complaints expected to be resolved within 30 days | No Gamstop obligation |
| Kahnawà:ke | Client provider application fee rising to USD 40,000 from 1 January 2027, plus USD 20,000 a year | Full-time dispute resolution officer | Its own voluntary self-exclusion is permanent and irrevocable |
| Costa Rica | No comprehensive licensing regime | Nothing | Nothing |
The Curaçao column deserves a second look, because it changed recently and a lot of sites have not caught up. The National Ordinance on Games of Chance took effect on 24 December 2024, replacing the old master-licence model with direct licensing by the Curaçao Gaming Authority. The legacy "orange" sub-licence certificates ended on 15 October 2025. Licensing by the four former master licensors ceased on dates between 18 August 2024 and 31 January 2025. And the CGA said on 7 October 2026 that its previous online portal would not return to service, with an alternative domain-verification mechanism still being built. A site showing a historic /JAZ number or an old seal is showing you a souvenir, not a licence.
The Payout Problem Nobody Puts in the Advert
Withdrawals are the point at which the offshore welcome turns cold, and the British data on the onshore market shows what a functioning payout process looks like. Gambling Commission data covering June to September 2024 recorded 44.2 million withdrawals by customers of large online operators; 96.3 per cent cleared automatically, 3.5 per cent within 24 hours and 0.1 per cent took up to 48 hours. Those figures come from the Commission's own speech of 6 November 2025. They are not a benchmark any unlicensed site promises, and the comparison is the entire argument.
It is not that onshore payouts are frictionless. They are not. Withdrawal problems were the number one topic raised with the Commission's Contact Centre, and the Commission's Annual Report and Accounts 2024-25 records that, despite work with some operators, withdrawal issues continue to cause most of the complaints it receives. Complaints coded "withdrawals and/or financial transactions" stood at 1,791 in the year to December 2025, down from 2,416 in the year to December 2022. Consumer research published on 23 July 2026 found 49 per cent of people who had gambled in the past 12 months agreed it was quick and easy to withdraw winnings; 18 per cent disagreed. So even the licensed market is imperfect. The difference is that a licensed operator has a rulebook aimed at exactly this friction, and an unlicensed one does not.
Onshore, four rules press on withdrawals. Reverse withdrawals were banned outright for all remote operators through requirement 14B, in force from 31 October 2021. Licence condition 17.1.1 says a withdrawal request must not generate a demand for information the licence holder could reasonably have asked for earlier. Licence condition 7.1.1 requires terms to be fair within the meaning of the Consumer Rights Act 2015. And the Commission's fair-terms guidance forbids any maximum limit on what a customer may withdraw from their deposit balance — the sort of term that reads "you may withdraw up to £50 per day". Compound interest builds slowly on that side of the fence. In October 2026 the Commission announced that one operator would pay £900,000 in a regulatory settlement for failures including unnecessarily delaying consumer withdrawals, one of them a term allowing only one withdrawal at a time.
Offshore, the equivalent protection is whatever the terms and conditions say, and they are usually drafted to say a great deal. In one case a prominent offshore brand reserves the right to limit withdrawals from winnings generated with bonus funds to 300 per cent of the credited bonus amount and to void the excess. That is not a delay. That is a ceiling, written in advance, on money that appeared on the screen.
Bonus Terms Are Where the Delay Is Built In
The bonus is the mechanism through which an offshore site buys time. Onshore, since 19 January 2026, wagering requirements on bonus funds are capped at ten times under social responsibility code 5.1.1, and mixed-product promotions requiring two or more types of gambling are banned. The Commission chose the cap over smaller thresholds and over an outright ban, noting that some licensees had applied wagering requirements of up to 60 times. Ten is the ceiling in Britain. It is not the ceiling elsewhere.
Offshore multipliers commonly quoted run from 25× to 40× on welcome offers, with no-deposit bonuses often at 40× to 60× and a cashout cap of €50 to €100. Those ranges come from trade and casino-guide comparisons rather than a regulator. One offshore operator states plainly that a 25× playthrough applies before winnings derived from a bonus may be withdrawn, that the multiplier can be expressed against the bonus alone or against bonus plus deposit, and that contributions to that playthrough vary wildly by game: slots and specialty games 100 per cent, table games 20 per cent, video poker and blackjack 10 per cent, roulette and baccarat 5 per cent, and craps or live dealer games 0 per cent unless stated otherwise. The last figure is the sting. A player can wager all evening on a game that contributes nothing at all to the requirement they believe they are clearing.
Two further terms do the quiet work. The first is a maximum bet while a bonus is active — €5 for regular players at one offshore operator, €10 for VIPs, with anything above it rejected. The second is the bonus-abuse clause, which lists prohibited patterns of play such as low-margin or equal-risk bets, moving from a low-weighted game to a high-weighted one after a large win, and delaying free spins until after wagering is met. British guidance requires such promotional play restrictions to be specified rather than left to the operator's sole discretion; offshore terms typically reserve exactly that discretion. Anyone comparing offers should read those two clauses before the headline number, because the headline number is the part written to be read.
And a reminder that belongs in this section rather than a footnote: the exclusion term holds regardless. A Gamstop registration set for six months, a year, five years, or five years with auto-renewal runs for its full length, cannot be cancelled part-way, and then continues until the person contacts Gamstop to remove it. An unlicensed site accepting a deposit changes nothing about that, and no offshore brand can remove a registration.
Five Signs an Offshore Operator Can Be Trusted
Trust here is a ladder, not a switch. A site can be honest about its terms and still be outside every protection that matters in Britain. What follows is the order in which I would look.
A licence that survives being clicked
A legitimate regulator lets anyone verify a licence against its own register rather than a picture in a footer. Under the Curaçao Gaming Authority's certification policy, a Certificate of Operation Seal must redirect to the authority's own certificate page, and if the certificate behind the seal names a different domain from the site being visited, that certificate belongs to another operator. Quick check: click the seal. If it does not go anywhere verifiable, or the domain on the certificate does not match the address bar, the licence claim is decoration.
Terms that state the maximum payout, not just the maximum bonus
Look for the words that limit what can be withdrawn. A term capping winnings from bonus play at a multiple of the bonus, or allowing only one withdrawal at a time, is a term designed to be met rarely. Quick check: search the terms page for "maximum", "cap" and "withdraw" and read every hit. Onshore, such terms are prohibited as unfair; offshore, they are ordinary.
A dispute route with a real name attached
Anjouan requires licensees to designate an authority-approved ADR provider and to print its name and contact details in the player-facing terms; the approved names currently include EGIS ADR, Axion ADR, iGaming ADR and one service provider. Kahnawà:ke employs a full-time dispute resolution officer. A site with an office in the Comoros and no dispute provider at all has told you what it expects to happen. Quick check: search the site for "complaints", "ADR" or "dispute" and see whether a named body appears.
Processing times in writing, with a period
A trustworthy operator publishes how long a withdrawal takes and does not change the answer when a request arrives. The Gambling Commission's own data gives the onshore standard: 96.3 per cent of 44.2 million withdrawals cleared automatically in June to September 2024. Quick check: find the published payout window. If the only timing language is "within a reasonable time" or "subject to review", treat the payout as open-ended.
Honest language about what the licence does not do
The strongest signal is an operator that says what it cannot do. Anjouan Gaming itself stated on 10 June 2026 that an Anjouan licence "is not, and has never been presented as, a universal authorisation to operate in every country in the world", and that no licensing authority can exempt an operator from local law where local authorisation is required. A site that copies that honesty into its own terms — naming its regulator and naming its limits — is doing more than most. Quick check: does any page admit the licence is not a British one? Silence is the tell.
Six Steps I Would Work Through Before Depositing
None of these steps is unusual or unlawful. They are the checks a careful person makes about anything with a name and a domain.
- Look up the licence on the regulator's own register, not on the site. Copy the licence number from the footer and find it on the authority's published list. Reason: a certificate image is a file, and a file can be copied onto any domain. A register entry belongs to one operator.
- Read the withdrawal section of the terms before the bonus section. Locate the processing window, any per-withdrawal cap, and any clause about reviewing withdrawals manually. Reason: bonuses are advertised to be read and withdrawal terms are written not to be, and the withdrawal terms govern the money that is actually won.
- Check the bonus multiplier, the game-weighting table and the maximum bet. Note the multiplier, then find which games contribute what, then find the bet limit while wagering. Reason: a 25× requirement on a game contributing 5 per cent is arithmetically a 500× requirement, and the table is where that is disclosed.
- Find the named dispute provider and the complaints deadline. Identify the ADR body in writing and check how long after an incident a complaint can be made. Reason: an unlicensed operator cannot be pursued through the Gambling Commission, which is a regulator and not an ombudsman and cannot recover money for an individual.
- Establish what happens to a balance if the operator fails. A remote operator licensed in Britain must keep customer funds in a separate client account and publish one of three protection ratings; offshore sites frequently publish nothing. Reason: the rating is not a guarantee even onshore — separation does not mean a refund on insolvency — and its absence offshore tells you the question was never asked.
- Set the controls that do not depend on the operator's goodwill. A bank-level gambling block, applied per card, plus blocking software such as Gamban or BetBlocker, which the Gamstop scheme itself signposts. Reason: a block at the card or the device sits between the impulse and the deposit, and it works whether or not the site wants it to.
The Brand Does Not Choose Whether the Exclusion Ends
The casino pay-by-mobile question gets asked in two moods, and both deserve a straight answer. If the question is whether a pay-by-mobile site can beat a self-exclusion, the answer is no, and not in the way the question usually expects. It is not that the site has been outfaced. It is that the registration itself does not lapse, and the only party who can end it is Gamstop Online, on request, after the term has run. There is no product, no payment method and no app that removes it.
If the question is instead about the practical mechanics — how much can be charged to a phone bill, how quickly a payout is processed, whether an offshore site honours its own terms — then the five checks above are the honest answer, and most of them fail. The licence authority that costs EUR 17,828 a year and posts a public fee schedule on its own website accepts no duty to a British self-exclusion, and says so. The Curaçao authority requires licensees to segregate player funds and certify random number generators, at a price of EUR 47,450 a year, and holds no power over a balance once it leaves the island's jurisdiction.
Britain's own numbers are not flattering either, and honesty requires admitting it. Payout problems remain the largest single category of complaint the Commission receives, and the Commission has had to fine a licensed operator £900,000 in part over withdrawal delays. The difference is not that the onshore market is comfortable. It is that onshore, someone with a rulebook can do something about it, and the four rules on withdrawals — the 14B reverse-withdrawal ban, condition 17.1.1, condition 7.1.1 and the prohibition on withdrawal caps — give a complaint somewhere to land.
Which brings it back to the term. Self-exclusion holds for as long as it was set, and then it holds until Gamstop Online is asked to end it, and that is the whole of the mechanism.
Questions About Mobile Casinos Outside the Scheme
Can I pay by mobile phone bill casino not on GamStop, and is it safe?
The deposit will usually go through, because carrier billing is a private arrangement between a merchant and a phone network and involves no licence check by the Gambling Commission. Safe is a different question. No onshore operator can offer a method outside the Payment Services Regulations 2017, licence condition 5.1.2, effective 31 January 2024. Offshore, the payment rail carries no complaint route, no dispute provider and no compensation mechanism if the operator stops answering.
Does pay by mobile bypass self-exclusion?
No, and the premise is worth correcting. A self-exclusion registration is not a barrier the site can be argued past; it is a record that simply persists. A Gamstop term holds for its full length and then continues until Gamstop Online is contacted to remove it. What an unlicensed site offers is a depositing route into an operator that never had to check the register — not an end to the exclusion itself. The Commission warned the industry on 20 January 2025 that unlicensed sites often target self-excluded customers.
Mobile deposit casino not on GamStop — how long does a withdrawal take?
There is no set answer offshore and no rule requiring one. For comparison, the Gambling Commission's data covering June to September 2024 found 96.3 per cent of 44.2 million withdrawals at large online operators cleared automatically. Onshore there is still no fixed maximum number of days in the licence conditions; the regime relies on fair terms, condition 17.1.1 and the unfair-terms prohibition instead. Offshore, the published window is the only promise, and "subject to review" is not a window.
How long does a self-exclusion last, and can I end it early?
Six months, one year, five years, or five years with auto-renewal, and no, it cannot be ended early. Under the terms of use, auto-renewal may only be switched off during the last six months of a five-year period, and auto-renewal can continue for up to four further five-year periods. If nothing is done after the chosen term, the scheme holds the data through a further automatic seven-year period during which operators are told the person was previously excluded.
What happens to my money if an offshore operator goes under?
Assume nothing comes back. Onshore, a remote operator must keep customer funds in a separate client account and publish one of three protection ratings — not protected, medium or high — but the Commission states clearly that separation does not mean customers are repaid on insolvency, and that businesses may hold customer money in overseas accounts. Money staked in an open bet is not customer funds at all. Offshore, no equivalent disclosure is required or commonly given.
Where do I get help if a mobile site has become a problem?
GamCare's National Gambling Helpline is free on 0808 8020 133, 24 hours a day, every day, with live chat and WhatsApp on the same number; callers in Wales can use 0808 2819 265. Gamblers Anonymous England, Wales and Ulster is on 0330 094 0322, and Citizens Advice Scotland's gambling support line is 0800 328 1131, Monday to Friday 10am to 3pm. The helpline is not a crisis line, so immediate risk needs the emergency services instead.
The Short Version
A licence you cannot verify, a withdrawal window written to be open-ended and an exclusion that does not end when the term does — that is the whole of mobile casinos outside the scheme, and the Curaçao Gaming Authority's own certification policy makes the first part easy to test, since a genuine Certificate of Operation Seal must redirect to its register and a mismatched domain means the certificate belongs to someone else. As of 13.11.2026, the term still holds until Gamstop Online is asked to lift it, and the helpline on 0808 8020 133 is free at any hour if the arithmetic stops adding up.
