What is Boku?

Boku is a mobile-billing payment provider that lets casino players deposit by adding the charge to their phone bill instead of using a card, e-wallet, or bank transfer. You confirm a payment with your mobile number and a text message, and the amount either appears on your monthly contract bill or is drawn from your pay-as-you-go credit. No bank or card details are shared with the operator, which is the method's main privacy draw. In practice, Boku is a deposit-only, pay-by-phone method: you can pay money in, but you cannot withdraw winnings back to your phone bill. Winnings must be cashed out to a separate verified method such as a bank account or e-wallet. Deposits are instant and are capped low by design, since mobile-billing rails are built for small, quick top-ups rather than large funding. Worked example: you deposit £10 via Boku and it credits your casino balance in seconds, with the £10 later itemised on your phone bill. Most UK operators enforce a £30-per-day Boku limit, so three £10 deposits in a day would hit the ceiling. Historically some carriers or aggregators added a fee of up to around 15% on gambling charges, meaning a £10 deposit could cost £11.50, though many casinos now absorb or waive this. For players, the low daily cap and phone-bill delay double as a natural spending brake, which suits budget control. For affiliates, Boku and other pay-by-phone options convert well with mobile-first, unbanked, or privacy-conscious audiences but rule out one-click withdrawals. Compare with pay-by-phone-casino, paysafecard, muchbetter, and prepaid-card.
