What is Siru Mobile and how it works in casinos
Siru Mobile was founded in Finland in 2011 and is operated by Siru Mobile Oy. It began as a way to pay for parking and small services by phone and expanded into online gaming, where it became popular with Finnish and Swedish players who wanted to avoid bank and card payments. The service works through agreements with mobile networks, which bill the amount to your monthly invoice or deduct it from prepaid credit.
At a casino, you choose Siru Mobile, enter your phone number, receive a call or SMS to confirm, and the deposit is credited instantly. Monthly limits are set by Siru and the carrier, and the casino applies its own caps. The method is offered by casinos targeting Finland, Sweden, Norway and the UK.
Depositing with Siru Mobile
Select Siru Mobile at the cashier, enter an amount of at least 10, type your mobile number and confirm via the automated call or SMS. The deposit is instant and appears on your next phone bill. Siru enforces a monthly limit per phone number, typically a few hundred in local currency, and the carrier may require you to enable premium services first. The fee is shown before you confirm.
Withdrawing winnings to Siru Mobile
Siru Mobile cannot receive withdrawals; a phone bill has no mechanism for incoming payments. Under the closed-loop policy the casino will ask you to add a bank account or e-wallet in your name and complete KYC before releasing winnings. Nordic players typically use Trustly or Zimpler for payouts, both of which pair well with Siru deposits.
Fees
Siru Mobile deposits carry a carrier fee of up to 10% of the amount, charged on top of the deposit and shown on your phone bill, which makes it the costliest method in our rating. Casinos do not add their own charge, and there is no currency conversion since the bill is in your local currency. The only way to minimise the cost is to use Siru sparingly for small top-ups and to switch to Trustly or Zimpler, which are free, for regular play.
Bonus eligibility
Siru Mobile deposits are sometimes excluded from welcome bonuses. Operators cite the low verification of phone-number payments and the risk of disputed carrier charges, and the fee structure makes it unattractive for bonus accounting. Some casinos allow it; check the terms, and if the bonus matters, make the qualifying deposit with a bank method instead.
Pros
- Deposit with only a phone number
- No bank or card needed
- Instant credit
- High privacy from your bank
Cons
- Carrier fees up to 10%
- Deposit-only; winnings paid elsewhere
- Low monthly limits
- Only in Finland, Sweden, Norway and the UK
Verdict
Siru Mobile is a last-resort convenience for Nordic players who cannot or will not use a bank method and want to top up small amounts privately. For anyone else the fee is hard to justify when Trustly, Zimpler and Open Banking offer free, instant deposits and withdrawals in the same markets. Use it occasionally, not as a main method.
