What Is a Boku or Pay by Mobile Casino Bonus?
A Pay by Mobile casino bonus, or Pay by Mobile bouns, is any welcome offer that activates after you fund your first deposit via Boku’s “Pay by Mobile” gateway, charging the amount to your UK phone bill or PAYG credit. Because the payment is treated like a standard cash deposit, Boku bonuses can take many forms:
- Deposit-match cash rewards (e.g. 100 % up to £100 at Duelz, Hyper or Mega Riches).
- Free-spin bundles tied to one or more qualifying slots (Mr Q’s 20 wager-free spins on Book of Dead).
- Prize-wheel or Mega Reel spins that can award up to 500 bonus spins (Luckstars, Win British).
- Tiered multi-deposit packages totalling as much as £1 000 + 100 FS (Monster Casino).
The only requirement is that your first payment is processed through Boku/Pay via Phone and meets the casino’s minimum (usually £10–£20).
How to Claim a Pay by Mobile Casino Bonus
Claiming a Pay by Mobile casino bonus will vary from operator to operator. But here are the common steps to claiming and activating your Boku or Pay by Phone Bill welcome bonus.
- Pick a Boku-ready site. Confirm the “Pay via Phone” logo in the cashier.
- Create your account. Enter accurate KYC info and a valid UK mobile number.
- Select “Pay by Phone Bill” in the deposit screen. Choose £10–£30 (within the carrier cap).
- Approve the SMS. Reply “YES” or enter the one-time code to authorise the charge.
- Launch the qualifying game or bonus wheel. The bonus credits automatically once the deposit clears.
- Complete wagering. Play through 30×–65× (if required) before requesting a withdrawal.
Why Are Some Casino Bonuses Not Eligible for a Pay-by-Mobile Deposit?
Most UK casinos now accept Boku for welcome offers, but exclusions still appear for three main reasons:
- Processing costs – payment providers may charge the operator up to 15 % per Boku transaction, so a few brands exclude the method or add a surcharge.
- Low carrier limits – the £30 daily cap can’t fund high-value welcome packages (e.g. “200 % up to £500”), so sites restrict Boku to smaller promos.
- One-way payments – Boku is deposit-only, which complicates “withdraw to same method” AML rules; some operators therefore block Boku for bonuses that require matched withdrawal channels.
Note: Every casino in our 2025 shortlist allows Boku deposits for its headline welcome bonus, but always scan the T&Cs for a payment-method exclusions line before you deposit.
