Pay by Phone Casino Not on GamStop 2026: The Complete UK Guide

Pay by phone casinos let you fund your account by charging the deposit directly to your mobile bill or prepaid credit – no card details entered, no bank login required. At UK-licensed sites that means navigating £30 daily ceilings and a credit card ban that still frustrates a significant chunk of players. At offshore casinos not on GamStop, the picture is different: more payment options, higher limits on some methods, and no GamStop data sharing. This guide covers how pay by phone actually works offshore, which providers you’ll find, what the real limits are, and the one thing most guides don’t tell you upfront – that you can’t withdraw via phone bill, and here’s what to do instead.

Our Top Pay by Phone Casinos Not on GamStop

These four have been tested for deposit speed, minimum deposit thresholds, and mobile usability. Details on each are in the individual sections below.

What Is a Pay by Phone Casino?

Pay by phone gambling means your deposit is charged to your mobile account rather than processed through a bank. There are two ways this happens:

• Carrier billing – the charge goes directly onto your monthly phone bill or deducts from your prepaid credit. You don’t need a bank card to do this; your SIM card is effectively your payment instrument.
• Mobile wallet – services like Apple Pay and Google Pay act as an intermediary, processing the deposit through a card or bank account linked to your phone’s wallet. This is technically “pay by phone” in the sense that your phone authorises the transaction, but it’s not carrier billing.

The distinction matters because the limits, privacy levels, and provider availability differ significantly between the two. Most players searching for pay by phone casinos want carrier billing – the option where no card is needed at all. Others want Apple Pay as a convenient one-tap alternative. This guide covers both.

How Pay by Phone Works at Non-GamStop Casinos

At a UK-licensed casino, pay by phone deposits go through the same KYC and GamStop verification as any other payment method. Your mobile number is logged, and if you’re on the GamStop register, you’ll be blocked.

At offshore casinos operating outside UKGC jurisdiction, the process is cleaner. When you use carrier billing:

1. You select “Pay by Phone” or the specific provider (Siru Mobile, Zimpler) in the cashier
2. You enter your mobile number – no card details
3. The casino sends a PIN or prompts biometric confirmation on your phone
4. You confirm, and the amount is charged to your mobile bill or prepaid balance
5. The funds appear in your casino account typically within a few seconds to a few minutes

The casino receives confirmation from the mobile operator that the charge has been authorised. Your name and bank details are never shared with the casino – only your mobile number and the confirmation that payment was approved.

Pay by Phone Providers at Offshore Casinos

Not all pay by phone services work the same way, and the provider makes a significant difference to your limits and experience.

Siru Mobile

Siru Mobile is the most commonly found carrier billing provider at best non-GamStop casinos - New casinos not on gamstop. Unlike Boku, Siru doesn’t have the same deep integration with UKGC compliance infrastructure, which is why offshore operators prefer it. It works through your existing UK mobile contract or prepaid credit.

Typical Siru deposits clear in under a minute. Minimum deposits are usually £10, and daily limits depend on your mobile carrier – most UK networks set carrier billing at £30–£50 per day regardless of which casino you’re using, since the limit is set by the network, not the casino.

Boku

Boku is the dominant carrier billing provider in the UK, but you won’t find it at offshore casinos. Boku operates in compliance with UKGC requirements, which means it participates in responsible gambling data sharing and enforces the £30 daily limit as a regulatory obligation. Offshore operators avoid it specifically because it connects to the same infrastructure GamStop uses. If you see Boku at a site, that site has UKGC licensing.

PayForIt

PayForIt is a UK carrier billing consortium supported by EE, O2, Three, and Vodafone. It appears at some offshore sites but is less common than Siru Mobile. Like Boku, PayForIt’s roots are in UKGC-regulated markets, and it enforces carrier-level daily limits. Where you do find it offshore, it works in the same way as Siru – deposit charged to your bill, no card required.

Zimpler

Zimpler is a Scandinavian mobile payment provider that several offshore casinos have added as an alternative to UK carrier billing. It works slightly differently: rather than charging your phone bill, Zimpler processes through a bank or card linked to your mobile number. For UK players it’s a pay-by-phone experience in terms of UX – one-tap, SMS confirmation – but it’s functionally closer to an e-wallet than carrier billing. Useful if your carrier doesn’t support direct billing at a particular site.

UK Carrier Limits for Pay by Phone Gambling

This is the question most guides dodge. The £30 daily limit on carrier billing isn’t set by casinos – it’s set by UK mobile networks. Even at offshore sites using Siru Mobile or PayForIt, if you’re on an EE, O2, Three, or Vodafone UK contract, you’ll hit a carrier-imposed ceiling.

Typical limits per network:

Network	Daily Carrier Billing Limit	Monthly Cap
EE	£30	£240
O2	£30	£240
Three	£30	£240
Vodafone	£30	£240
Giffgaff	Not supported	–
SMARTY	Not supported	–

MVNOs (virtual networks like Giffgaff, iD Mobile, SMARTY) often don’t support carrier billing for gambling at all, since they piggyback on the main networks but don’t always pass through billing capabilities.

If £30 per day isn’t enough, the practical solution at offshore casinos is to use Apple Pay or Google Pay linked to a credit card, or to use an e-wallet or crypto. These aren’t subject to carrier billing caps.

Apple Pay and Google Pay at Non-GamStop Casinos

This is where offshore casinos have a clear advantage over UK-licensed sites. The UKGC banned credit card deposits in April 2020. UKGC-licensed casinos are therefore not allowed to process transactions where the underlying funding source is a credit card – including when a credit card is linked to Apple Pay or Google Pay.

Offshore casinos are under no such obligation. Most of the non-GamStop casinos - Non gamstop casinos listed on this page accept Apple Pay and Google Pay, and the underlying card can be a credit card. For players who want the convenience of one-tap mobile deposits without the £30 carrier billing ceiling, this is the primary alternative.

Limits via Apple Pay/Google Pay are set by the casino rather than the carrier, typically ranging from £10 minimum to £5,000+ per transaction depending on the operator.

Can I Withdraw via Pay by Phone?

No. This is standard across the industry – carrier billing is deposit-only. You cannot reverse a phone bill charge back to your casino account, and mobile networks don’t support outward money transfers for gambling. This applies at both regulated and offshore casinos without exception.

Before you make your first pay by phone deposit, set up a withdrawal method. Your options at non-GamStop casinos:

• E-wallets (Skrill, Neteller): The most common offshore withdrawal route. Typically processed within a few hours to 24 hours. You’ll need to verify your e-wallet account separately, but once done, withdrawals are usually smooth.
• Bank transfer: Available at most offshore casinos but slower – typically 1–5 business days. Requires standard identity verification first.
• Cryptocurrency (Bitcoin, Ethereum, USDT): The fastest option at casinos that offer it. Processed within minutes to a couple of hours once approved. Requires a crypto wallet.
• Debit card: Available at many offshore casinos for withdrawals even where credit cards aren’t accepted for deposits.

Don’t wait until you have a winning balance to set this up. Complete identity verification and add a withdrawal method as soon as you open your account.

Lolo Casino

Lolo’s cashier includes mobile wallet support and loads quickly on phones. Minimum deposit is £10. The welcome package runs across three tiers, so your initial mobile deposit unlocks the first match immediately. Withdrawal options include e-wallet and bank transfer.

Sankra is one of the cleaner no-KYC options – you register with an email address and can deposit and play without uploading documents at sign-up. Verification is triggered on withdrawal rather than at registration. Useful for players who want to move quickly. Minimum deposit £10.

Pros and Cons of Pay by Phone at Offshore Casinos

Pros:

• No card details shared with the casino – only your mobile number
• Instant deposits in most cases
• No bank account needed for carrier billing
• Apple Pay/Google Pay option allows credit card use that UKGC sites don’t permit
• Works even if you don’t have a debit card

Cons:

• Carrier billing capped at £30/day by UK mobile networks regardless of casino
• Cannot withdraw via phone bill – must set up a separate method
• Not all offshore casinos support carrier billing (some are card and crypto only)
• MVNO customers often can’t use carrier billing at all
• If you have gambling transactions on your phone bill, they may be visible to anyone who shares the account

Is Pay by Phone Safe at Offshore Casinos?

Carrier billing is a secure payment method. Your card details and bank account aren’t exposed because neither is involved. The casino receives a payment confirmation token, not your personal financial data.

The security consideration at offshore casinos is the same as any other payment method: it depends on which casino you’re using. A casino holding a verifiable Curaçao or Anjouan licence that has a track record of paying withdrawals is meaningfully different from an unlicensed operation. Before depositing via any method:

• Check the licence number in the footer and verify it with the issuing authority
• Test customer support before depositing – ask a specific question about withdrawal times
• Start with a small deposit to test the process before committing larger amounts

Step by Step: How to Deposit via Pay by Phone

1. Register at your chosen offshore casino. You’ll need an email address and mobile number.
2. Navigate to the cashier and select “Deposit.”
3. Choose your pay by phone provider – look for Siru Mobile, Zimpler, Apple Pay, or Google Pay depending on what the casino offers.
4. Enter the deposit amount within the provider’s limits.
5. Confirm on your phone – via SMS PIN, FaceID, or TouchID depending on the method.
6. Check your balance – carrier billing deposits typically credit within seconds.
7. Set up your withdrawal method before you play – add an e-wallet address, bank details, or crypto wallet to your account while you remember.

Responsible Gambling

Pay by phone casinos not on GamStop do not participate in GamStop’s self-exclusion scheme. If you’ve self-excluded through GamStop, these sites will not block your access.

Carrier billing and mobile wallet deposits are fast and require minimal friction – which is convenient, but also means impulse control matters more than at sites with mandatory cool-off periods or deposit limits.
