Boku is a mobile billing service that lets you deposit at online casinos by charging the amount to your phone bill or prepaid credit — no bank details, no card number, just your mobile number. It's one of the most private deposit methods available to Irish players, though it comes with low daily limits and no withdrawal capability.
How Boku Works at Irish Online Casinos
Boku acts as a bridge between the casino and your mobile network operator. Here's the process step by step:
- In the casino cashier, select Boku or "Pay by Mobile"
- Enter your Irish mobile number and choose the deposit amount
- Receive a confirmation SMS from Boku
- Reply "YES" (or tap the confirmation link) to authorise the charge
- The deposit appears in your casino account instantly
- The charge is added to your next phone bill or deducted from your prepaid balance
The two-step SMS confirmation means that even if someone knows your mobile number, they cannot trigger a Boku deposit without access to your phone.
Boku Deposit Limits — The Key Constraint
Boku's low limits are set by Irish mobile network operators, not the casinos. Typical limits:
📲 Boku Limits at Irish Casinos
- Minimum deposit: €5–10
- Maximum single deposit: €10–30
- Daily limit: €30 (most networks)
- Monthly limit: may vary by network contract
- Withdrawals: Not supported
These limits make Boku unsuitable for high-volume play. It's best suited to players who want a small, controlled deposit with no bank account exposure.
Privacy Benefits
Boku's main advantage is privacy. No card number, sort code, or bank account number is ever shared with the casino. The deposit shows on your phone bill as a third-party service charge, which is less identifiable than a direct casino debit. For players on prepaid SIMs who don't use a bank account for gambling, Boku offers a rare card-free deposit route.
Irish networks Eir, Three, and Vodafone all support Boku billing. If you're on a smaller MVNO, check the casino's cashier to confirm your network is listed.
Withdrawals — You'll Need a Different Method
Boku cannot process withdrawals. Mobile billing infrastructure only flows in one direction — from customer to merchant. Before you deposit via Boku, register a withdrawal method in the casino cashier: a Visa or Mastercard Debit card, Revolut, e-wallet (Skrill, Neteller), or your bank IBAN. This ensures you can cash out without delays when you're ready.
Many players use Boku for deposits and Revolut for withdrawals — combining the privacy of phone billing with Revolut's fast payout processing. See our fast payout casino guide →
