Pay by Mobile Casinos
Pay by mobile casinos let you deposit using your phone bill or prepaid mobile credit instead of a card, bank account or e-wallet. You pick the option in the cashier, confirm by SMS, and the amount is added to your monthly bill or taken from your pay-as-you-go balance. No card numbers, no bank details — just your mobile number.

Here is the context that shapes this whole guide. “Pay by mobile” is the umbrella category, and underneath it sit several carrier-billing providers: Boku, Fonix, Payforit and Siru Mobile. Boku was the dominant name a few years ago, but it has largely been phased out at UK casinos since the 2020 credit-card ban — and the category survived by moving to Fonix, Payforit and Siru. So the modern reality is simple: you usually won’t see a “Boku” logo any more, but you will still find “Pay by Mobile” at a small number of casinos, powered by one of those newer providers.
That means there are two honest routes today, and we cover both. First, a handful of casinos offer Pay by Mobile directly in the cashier — in our portfolio, Duelz (via Fonix) and Mr Vegas (via Siru) are the genuine direct options. Second, everywhere else you fund a Neteller wallet by phone and deposit with Neteller, which reaches a much wider set of casinos. Whichever route you use, it’s deposit-only: a phone bill can’t receive winnings, so you cash out by card, bank transfer or e-wallet.
Pay by Mobile at a Glance
- Direct in the cashier: Duelz (Fonix) and Mr Vegas (Siru Mobile)
- Everywhere else: fund Neteller by phone, then deposit by Neteller
- The providers: Fonix and Payforit now carry the category; Boku has mostly gone; Siru powers the Videoslots/Mr Vegas family
- Daily cap: roughly £30–£40 a day, set by the provider and your network — not the casino
- Deposit-only: withdraw by card, bank transfer or e-wallet
- Networks: EE, O2, Vodafone and Three all support carrier billing
- Speed: instant on SMS approval
How Pay by Mobile Works
Carrier Billing, Not a Wallet
Pay by mobile charges your deposit to your phone account rather than taking it from a card, bank or e-wallet balance. It differs from PayPal, Skrill and Neteller (e-wallets with their own balances), from Trustly (bank authentication) and from Paysafecard (prepaid vouchers). Because carrier billing only moves money one way — into the casino — it cannot send winnings back, which is why every pay-by-mobile casino needs a separate withdrawal method.
Whether a casino offers it is set at the platform level, not by the brand on the front. In our portfolio, only Duelz and Mr Vegas surface Pay by Mobile directly; the rest require the Neteller route.
The Providers Behind the Button
Fonix powers most surviving direct Pay by Mobile in the UK, including Duelz — typically from £10, up to £40 a transaction and £240 a month. Payforit is the older network-backed framework still seen at some sites. Siru Mobile is the route used by the Videoslots family, including Mr Vegas. Boku was the original leader but is now rare at UK casinos. For the specifics on Boku itself, see our Boku casinos guide.
Depositing the Direct Way (Duelz, Mr Vegas)
Open the cashier, choose Pay by Mobile, enter the amount and your number, and approve by SMS. The balance updates instantly and the charge lands on your next bill or comes off your PAYG credit. A deposit fails only if your network blocks carrier billing, your credit is short, you exceed the cap, the number is wrong, or your account still needs verifying.
Depositing Everywhere Else (Phone → Neteller)
For casinos without direct Pay by Mobile, fund a Neteller wallet by phone (Neteller lists carrier billing under “Add money”), then deposit at the casino with Neteller. The daily phone-billing cap applies to the top-up, but once the money is in Neteller you can usually withdraw back to Neteller too.
What Makes a Good Pay by Mobile Casino?
UK Licensing and Protection
Every casino here is UK Gambling Commission licensed, which mandates identity verification before you gamble, plus deposit limits, reality checks and self-exclusion. A fast phone deposit never replaces those checks — you’ll still verify your name, address and date of birth before withdrawing.
Clear Deposit Limits
A trustworthy site states whether Pay by Mobile is accepted, the minimum and maximum, which networks work, and whether phone deposits qualify for the bonus. Duelz, for instance, states its Fonix limits openly: from £10, up to £40 per transaction and £240 a month. The cap is deliberately low, which makes the method a natural fit for controlled, small-stake play.
A Stated Withdrawal Route
Because no phone-bill method pays out, the best casinos make the cash-out route obvious before you deposit. The Neteller route has an edge here: money in via Neteller comes back out via Neteller. The rule that saves trouble: if you don’t know how you’d withdraw, don’t deposit yet.
A Genuinely Mobile-First Casino
The payment is phone-led, so the casino should be too — a smooth mobile cashier, simple SMS confirmation, document upload and live chat without switching to desktop. Mr Vegas and Duelz are both built mobile-first, which is partly why they support direct phone billing in the first place.

The casinos, and how to pay by phone at each
Duelz — The standout direct option, with Pay by Mobile built into the cashier and powered by Fonix — no Neteller step needed. Phone-bill deposits run from £10 (up to £40 a transaction, £240 a month) and, unusually, they qualify for the welcome offer of 140 free spins on a £25 deposit. Withdrawals, which can’t return to a phone bill, average around six minutes to other methods. For a genuine one-step phone deposit, this is the pick.
Pros: direct Pay by Mobile in the cashier, powered by Fonix · phone-bill deposits from £10 and they qualify for the welcome offer · withdrawals average around six minutes Cons: £25 deposit needed for the full 140-spin offer · £40-per-transaction and £240-monthly network caps

Mr Vegas — The other genuine direct option, with Pay by Mobile via Siru Mobile, the provider used across the Videoslots family. Behind the cashier sits one of the UK’s biggest libraries at 9,000-plus titles, with withdrawals from as little as £2 on some methods, and the welcome offer of 100% up to £50 plus 11 free spins is claimable by phone deposit.
Pros: direct Pay by Mobile via Siru Mobile, no e-wallet step · 9,000-plus games and withdrawals from £2 · phone-bill deposits qualify for the welcome offer Cons: £10 minimum · Siru limits are lower than card or e-wallet

Betnero — Reached by funding Neteller by phone, then depositing by Neteller. Betnero is one of the few sites where a Neteller-funded deposit still claims the welcome bonus — 100% up to £50 plus 50 free spins at a low 10x wagering — so the phone route doesn’t cost you the offer. Neteller payouts land within 24 hours.
Pros: reachable by funding Neteller with pay-by-mobile · a Neteller deposit still claims the 100% up to £50 welcome bonus · Neteller payouts within 24 hours Cons: no direct phone-bill option in the cashier · £10 minimum plus the Neteller step

Casumo — A polished, award-winning casino reachable via phone-funded Neteller, with 3,800-plus games and e-wallet payouts within hours. The welcome offer is a straightforward 50% match up to £100. Note the £3 fee on withdrawals under £10 — cash out £11 or more and it’s free.
Pros: reachable via pay-by-mobile-funded Neteller · 3,800+ games and fast e-wallet payouts · simple 50% match welcome Cons: no direct phone-bill option in the cashier · £3 fee on withdrawals under £10

BoyleSports — An established sportsbook-and-casino reachable via phone-funded Neteller, with a £10 minimum and up to 100 welcome free spins.

Betfair — Reachable via phone-funded Neteller, with fast Neteller and Visa payouts and a £5 standard minimum. New players get 50 free spins for joining, plus more after a £10 deposit — but to claim the welcome spins you must deposit by card or Apple Pay, so the Neteller route is for funding rather than the bonus.

Claim Offer Here
Paddy Power — Reachable via phone-funded Neteller, and the standout here for cash-outs: withdrawals start from a single penny to your debit card, so no small balance is ever stranded. The welcome package is 60 no-deposit spins plus 200 more after a £10 stake. Neteller deposits are excluded from that offer, so use the Neteller route to fund and claim the offer with a card.

Bonuses and Free Spins
Does a Phone Deposit Qualify for the Bonus?
It depends on the route. At Duelz and Mr Vegas, a direct Pay by Mobile deposit qualifies for the welcome offer. On the Neteller route it comes down to whether the casino lets Neteller claim its bonus: Betnero and Mr Vegas do; Paddy Power, 10Bet and Hyper do not (their offers need a debit card); and Betfair requires a card or Apple Pay for the welcome spins. The rule to remember is that a casino can’t usually add a bonus after a non-qualifying deposit, so match your method to the offer before you pay.
Free Spins
Free spins suit phone-bill play because the deposits are small. Judge them by the terms, not the headline: Betnero’s 50 spins sit behind a low 10x wagering, and Paddy Power’s 260 spins are wager-free, which beats a larger package with 40x playthrough. For wider comparisons, see our casino bonuses guide.
No-Deposit Offers
No-deposit bonuses don’t need any payment to claim, so the phone-bill question only arises later, when you make a qualifying deposit or withdraw. Those offers still carry their own caps and wagering, which a phone deposit does nothing to change.
Deposit Times, Limits and Costs
Speed
Both routes are quick. A direct Pay by Mobile deposit at Duelz or Mr Vegas clears instantly on SMS approval; a phone top-up to Neteller is equally fast, then the Neteller-to-casino deposit is instant. A deposit fails if your network blocks carrier billing, credit is short, you exceed the cap, the number is wrong, the SMS code expires, or verification is pending.
Limits
The daily cap — around £30 on Boku, up to £40 a transaction and £240 a month on Fonix — is set by the provider and your network, and applies whether you deposit directly or top up Neteller. Casinos add their own minimums: £5 at Betfair and Paddy Power, £10 at most others, £20 at SpinYoo. The cap is low by design, which makes phone-bill deposits a natural fit for controlled play. For more small-stake options, see our £5 deposit casinos guide.
Costs
Neither the provider nor your network charges you to use Pay by Mobile — the amount you deposit is the amount on your bill. The fee to watch for is on the casino side: a minority of operators add a handling charge to phone-bill deposits, so check the cashier line before you confirm. On the Neteller route, Neteller’s own terms apply to the top-up.
Contract vs Pay-As-You-Go
On a contract phone, the charge appears on your monthly bill; on PAYG it comes straight off your credit. Both work across the major networks, provided carrier billing is enabled on your account.
Withdrawals: What to Know
You Cannot Cash Out to a Phone Bill
Pay by mobile is deposit-only — a phone bill is a billing destination, not a payout account. You withdraw by debit card, bank transfer or e-wallet instead. The Neteller route has a built-in advantage: money that went in via Neteller can come back out via Neteller, often within 24 hours.
Verification and Ownership
Licensed casinos verify your identity before releasing funds, and the phone account and any payout method must belong to you. Complete verification when you register so a payout isn’t held up later, and keep your account, phone and payment details consistent.
Avoiding Cash-Out Problems
Set your withdrawal method up front, finish any bonus wagering before requesting a payout, and use a card or wallet in your own name. If you funded by Neteller, withdraw to Neteller for the fastest turnaround — see our fast withdrawal casinos guide.
Is Pay by Mobile Safe?
Carrier billing is secure: you share only a mobile number, never card or bank details, and every charge is confirmed by SMS. What it cannot do is vouch for a casino. A site is trustworthy because of its UKGC licence, fair terms, clear payout routes and safer-gambling tools — which is why every casino here is licensed and has a confirmed deposit and withdrawal route. And because phone deposits feel frictionless, set a deposit limit before you play, use reality checks and time-outs, and remember GAMSTOP covers every UK-licensed site and that many networks let you cap or block premium charges.
Casino Games at Pay by Mobile Casinos
The payment method affects the cashier, not the games. Across these casinos you’ll find classic and video slots, Megaways, jackpots and cluster-pays titles — Mr Vegas alone runs 9,000-plus — plus live roulette, blackjack, baccarat and game shows, and table games, video poker and instant wins. Because the cap keeps balances small, low-stake slots from 10p–25p a spin suit phone-bill play better than higher-limit live tables. For the full range, see our online casinos hub.
Pay by Mobile vs Other Methods
Versus Boku specifically: Boku is one provider within pay by mobile, and the one that has mostly left UK casinos; Fonix, Payforit and Siru now carry the category. See our Boku casinos guide.
Versus debit card: cards are direct and withdrawal-friendly; pay by mobile avoids card entry and caps spending, but is deposit-only.
Versus Apple Pay: Apple Pay is a card-linked wallet that deposits instantly and, at several casinos, pays back out too. See our Apple Pay casinos guide.
Versus PayPal and Neteller: both are e-wallets that handle deposits and withdrawals — and Neteller is the very wallet you fund by phone to reach the casinos above. Compare at our Neteller casinos and PayPal casinos guides.
Versus Trustly and Paysafecard: Trustly uses bank authentication and supports payouts; Paysafecard uses prepaid vouchers and, like pay by mobile, is deposit-only. See Trustly casinos and Paysafecard casinos.
Why a Deposit Might Be Declined
A deposit is declined if the casino doesn’t offer Pay by Mobile, your network blocks carrier billing, credit is too low, you exceed the cap, the number is wrong, the SMS code expires, verification is incomplete, or you’ve hit a limit you set. Confirm Pay by Mobile appears in the cashier (or use the Neteller route), check your carrier-billing setting, re-enter the number carefully, and complete verification. If billing is blocked, your mobile provider can lift premium-charge restrictions.
The Mobile Bill Cashout Readiness Test
Most pay-by-mobile pages focus on the instant deposit; the real friction is at cash-out, when players learn a phone bill can’t receive winnings. Our Mobile Bill Cashout Readiness Test scores how clearly a casino explains the whole journey, out of 10:
- Cashier visibility — is Pay by Mobile easy to find, or is it the Neteller route?
- Network clarity — are supported UK networks listed?
- Deposit-limit clarity — are the minimum and cap shown up front?
- Bonus eligibility — does a phone deposit qualify for the welcome offer?
- Fee transparency — are any casino-side phone-bill fees shown?
- Withdrawal explanation — does the casino state how phone-deposit users cash out?
- Alternative payout route — is card, bank transfer or e-wallet withdrawal explained?
- Verification timing — are KYC checks explained before cash-out?
- Mobile cashier quality — is SMS confirmation smooth on a phone?
- Support accuracy — can live chat explain phone deposits and the cash-out rule?
Duelz and Mr Vegas score highest, because the phone route is direct, qualifies for the bonus, and is stated openly in the cashier. The Neteller-route casinos score well on withdrawal clarity, since money in via Neteller comes back out via Neteller.
How to Choose
For a genuine one-step phone deposit: Duelz (Fonix) or Mr Vegas (Siru) — the two direct options. For keeping the welcome bonus via Neteller: Betnero or Mr Vegas, which let Neteller claim the offer. For the lowest entry: Betfair or Paddy Power at £5. For no stranded balances: Paddy Power, with 1p withdrawals. For the biggest libraries: Mr Vegas (9,000+) or Casumo (3,800+). For controlled spending: any phone-bill route, where the daily cap keeps deposits small.
FAQs About Pay by Mobile Casinos
Which casinos still offer Pay by Mobile directly? In our portfolio, Duelz (via Fonix) and Mr Vegas (via Siru Mobile). Elsewhere, fund a Neteller wallet by phone and deposit by Neteller.
Is Boku the same as Pay by Mobile? No. Pay by Mobile is the category; Boku is one provider within it, and the one that has mostly left UK casinos. Fonix, Payforit and Siru now power most direct phone-bill deposits.
Can I withdraw winnings to my phone bill? No. Pay by Mobile is deposit-only. Withdraw by debit card, bank transfer or e-wallet — Neteller is fastest if you funded that way.
What’s the maximum I can deposit by phone? Around £30 a day on Boku, and up to £40 a transaction and £240 a month on Fonix. Your network can set lower limits.
Does a phone deposit qualify for the welcome bonus? At Duelz and Mr Vegas, yes. On the Neteller route it depends on the casino: Betnero allows it, while Paddy Power, 10Bet, Hyper and Betfair need a card for the offer.
Can I use Pay by Mobile on a pay-as-you-go SIM? Yes, provided you have enough PAYG credit and carrier billing is enabled on your account.
Can I use someone else’s phone to deposit? No — use only an account you own or are authorised to use, as payment-ownership checks can hold up a later withdrawal.
Why does the casino ask for ID if I deposited by phone? A phone deposit doesn’t replace age and identity verification, which UK-licensed casinos must complete before you gamble.
Will a phone deposit affect my credit score? A phone-bill charge is not a credit application, so it doesn’t directly affect your score. An unpaid phone bill can cause wider issues, as with any bill.
What should I check before depositing by phone? The UKGC licence, whether the cashier offers Pay by Mobile (or whether you’ll use the Neteller route), the daily cap, any casino-side fee, your withdrawal method, and your own deposit limits.
