How £3 Phone Bill Deposits Work

The pay by mobile casino deposit flow is identical to a £5 or £10 Boku payment: enter your mobile number, reply “Y” to the SMS and watch the credit land in seconds. The difference is the provider: most £1 deposits ride Siru Mobile or PayviaPhone because Boku’s UK limit is typically £5.

What Are Micro Pay by Phone Bill Deposits?

Micro pay by phone bill deposits refer to small casino top-ups—typically between £10 and £30—that are charged directly to your monthly mobile bill or deducted from a pay-as-you-go balance. These deposits don’t require a card, bank account, or e-wallet. While fast and secure, withdrawals cannot be made via your phone bill and must go through other options like bank transfer or PayPal.

How Do I Make a Micro Deposit Using My Mobile Bill?

To deposit using your mobile:

  1. Join a UK-licensed casino that supports pay by mobile.
  2. Select the “Pay by Phone” or “Pay by Mobile” option at the cashier.
  3. Enter your UK mobile number when prompted.
  4. Approve the deposit via SMS confirmation.
  5. The funds will either be added to your next bill or taken from your prepaid balance.

Why Use Micro Pay by Mobile Deposits?

There are several benefits to making a micro deposit at an online casino for casual UK players:
