How We Review Pay by Phone Casinos Not on GamStop
We score every site above against the same framework we use across the site — licence, bonuses, software, support and payments — with a few pay-by-phone-specific checks:
- Genuine carrier billing. That the site truly supports Boku, Payforit or another phone-bill provider, not just a card-based “mobile” option dressed up as pay by phone.
- A workable withdrawal method. Since you can’t cash out to your phone bill, we check the alternatives (e-wallet, bank transfer) are fast and fair.
- Licensing and ownership (usually Curacao or Malta), bonus terms, withdrawal speed and limits, and customer support — tested the same way on every site.
If a casino fails on safety or payouts, no payment method saves it — it doesn’t make the list.
What Is Pay by Phone Bill?
Pay by phone bill (also called pay by mobile or carrier billing) lets you deposit using your mobile number instead of a card. The charge is either added to your monthly contract bill or deducted from your pay-as-you-go (PAYG, or prepaid) credit. You never share bank or card details — the casino only ever sees your phone number. You may see the option labelled carrier billing, SMS billing or simply “pay by mobile” — they all mean the same thing.
The two account types behave differently, and the difference matters:
- Contract (monthly bill): the deposit is added to next month’s bill — effectively “deposit now, pay later”.
- Pay-as-you-go (PAYG): the deposit comes straight out of your existing credit, so you can only spend what you’ve already loaded.
That second point — PAYG — is the safer route, for reasons we cover under responsible gambling.
How to Deposit by Phone Bill
Topping up by phone bill takes under a minute:
- Open the cashier and choose the pay by phone / pay by mobile option (it may be listed as Boku, Payforit or Fonix).
- Enter your UK mobile number.
- Enter the amount you want to deposit — double-check it, as it can’t be reversed once confirmed.
- Confirm by SMS — you’ll get a text with a code; enter it to authorise.
- Start playing — funds appear instantly, and the charge lands on your next bill or PAYG balance.
A few nuances worth knowing before you start:
- Set up a withdrawal method first. You can’t cash out to your phone bill, so add an e-wallet or bank option before you play, not after you win.
- PAYG users: load enough credit first — the deposit fails instantly if your balance is too low.
- The charge may show as the provider (Boku or Payforit) rather than the casino name, and often as a general purchase rather than “gambling”.
- Keep the SMS confirmation. If a deposit is charged but not credited, the dispute sits with the casino — contact support with that reference code.
Pay by Phone Providers: Boku, Payforit and Fonix
A handful of providers power phone-bill deposits, and the casino decides which one it uses:
- Boku — the dominant provider, FCA-licensed and publicly listed, working across all four major UK networks. If a site offers pay by phone, it’s most often via Boku.
- Payforit — a UK-only scheme built by the networks themselves. Still accepted, but being phased out in favour of Boku and Apple/Google Pay.
- Fonix and others — smaller carrier-billing providers you’ll occasionally see at the cashier.
All four major UK networks — EE, O2, Vodafone and Three — support phone-bill deposits, and most MVNOs (Giffgaff, Smarty and so on) piggyback on them.
| Provider | UK networks | Status | Withdrawals |
| Boku | EE, O2, Vodafone, Three | FCA-licensed, most common | Deposit only |
| Payforit | EE, O2, Vodafone, Three | UK scheme, being phased out | Deposit only |
| Fonix | Major UK networks | Smaller, less common | Deposit only |
Deposit Limits: the £30 Daily Cap
This is the most important thing to know, and it’s a UK feature you can’t switch off. Phone-bill gambling deposits are capped at roughly £30 per day and £240 per month, with minimum deposits usually £5–£10.
For most players that cap is a feature, not a bug: it’s one of the few spending controls that’s enforced at the network level rather than left to willpower. Crucially, that limit is set by your mobile network — and phone-paid services are overseen by Ofcom, which took over their regulation in February 2025 — not by the casino, so no operator, on GamStop or not, can raise it for you. But it does mean pay by phone is unsuitable for anyone wanting to deposit larger sums in one go.
Elliot Watson, non-gamstopcasinos.com: “The £30 cap is the single best built-in brake in the payments space — but only on PAYG. On a contract, you’re depositing on credit and the bill arrives weeks later, so three quiet £30 days become a £90 surprise you’d half-forgotten. If you’re using pay by phone specifically to control spending, use a pay-as-you-go SIM. That way the limit is your actual money, not future money.”
Fees and Why a Deposit Might Fail
Fees: in almost all cases there’s no charge to you for paying by phone bill — the casino absorbs the processor’s cut. If a site adds its own fee on top, treat that as a red flag.
If a deposit fails, the usual causes are simple: you’ve hit the £30 daily cap, your PAYG balance is too low, your network doesn’t support the casino’s provider, or gambling charges are blocked at the account level (common on family and business plans — your carrier can confirm and, where allowed, lift it). Because a confirmed SMS payment can’t be reversed, always check the amount before you approve it.
Can You Withdraw with Pay by Phone?
No — and this catches people out, so it’s worth stating plainly. Pay by phone is deposit-only. There’s no technical way to send winnings back to your phone bill; it’s a limitation of carrier billing itself, not a casino rule. You’ll need to set up an alternative withdrawal method — usually an e-wallet or bank transfer (note that prepaid options like Paysafecard can’t be used for withdrawals either, so an e-wallet is generally quickest). Sort this out before you play, not when you’re ready to cash out.
Pay by Phone at Non-GamStop Sites: What’s Actually Different
Here’s the honest part most pages skip. A top up by phone bill at a non-GamStop casino — sometimes searched as a casino not blocked by GamStop — works the same way technically; the difference is availability. Boku and Payforit are built around UK carriers and work most smoothly with UK-licensed operators. At offshore non-GamStop casinos, genuine phone-bill billing is less widely available — some support it, some route “pay by mobile” through other providers, and some only appear to offer it. So:
- Check the cashier, not just the homepage. Confirm Boku, Payforit or Fonix actually appears as a deposit option before you sign up.
- The £30 cap still applies, because it comes from your network, not the site.
- If a non-GamStop site doesn’t offer true carrier billing, a Boku casino or a low-minimum alternative is the better route.
Pay by Phone Bill Slots Not on GamStop
Once you’ve deposited, the full library is open to you — your payment method doesn’t limit which games you can play. That includes the big Megaways slots not on GamStop and live dealer tables such as Evolution live casino games. One practical note: with a £30 daily cap, low-stake play makes sense — pick games with small minimum bets so a capped balance lasts.
Bonuses with Pay by Phone
A common catch: many welcome offers either exclude pay by phone deposits or need a qualifying deposit larger than the £30 cap allows in one go. If a bonus needs £10 you’re fine, but a “deposit £50, get £50” offer can’t be claimed in a single phone-bill top-up. If the bonus matters more than the payment method, our £5 deposit and £10 deposit guides cover low-minimum options that usually do qualify. Always read the bonus terms before depositing.
Pros and Cons of Pay by Phone Casinos
Pros
- No bank or card details shared — just your phone number.
- Instant deposits, confirmed by a single SMS.
- The £30 daily cap is a genuine, network-enforced spending control.
- A GamStop self-exclusion doesn’t block registration at non-GamStop sites.
Cons
- Deposit-only — you can’t withdraw to your phone bill.
- The £30/day cap rules out larger deposits.
- Often excluded from welcome bonuses.
- On a contract, you’re effectively gambling on credit.
Is Pay by Phone Safe?
Yes — it’s one of the more secure ways to deposit. You never expose bank or card details to the casino, every transaction is confirmed by SMS two-factor authentication, and Boku itself is FCA-licensed. The bigger safety question is the casino, not the payment method: confirm the operator holds a valid licence. The two you’ll see most are Curacao-licensed casinos, the most common offshore option, and Malta-licensed casinos, a stricter framework. Because they’re licensed offshore, many also accept players from Ireland — see our Irish casinos not on GamStop guide if that’s you.
Responsible Gambling and Pay by Phone
Pay by phone has a real responsible-gambling upside — the network-level £30 cap genuinely limits how much you can lose in a day. But it has an equally real downside on contract phones: charging deposits to a bill you pay later is gambling on credit, and the cost only becomes visible weeks afterwards. GAMSTOP exists to let people step back when gambling stops being fun, and playing outside the scheme means that safety net isn’t there.
- Use a PAYG SIM if you’re paying by phone to stay in control — you can only spend money you’ve already loaded.
- Set deposit and loss limits on the site as well. Most reputable non-GamStop casinos offer them.
- Don’t treat the £30 daily cap as a daily target. It’s a ceiling, not a goal.
