£3 phone bill deposits: PayviaPhone Micro Deposits

£3 phone bill deposits, or micro deposits, are a good way to test the waters without risking more money. A handful of UK-licensed sites now accept ultra-micro top-ups via Boku, PayviaPhone or Siru Mobile.
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:
- Join a UK-licensed casino that supports pay by mobile.
- Select the “Pay by Phone” or “Pay by Mobile” option at the cashier.
- Enter your UK mobile number when prompted.
- Approve the deposit via SMS confirmation.
- 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:
- No card or banking information required.
- Payments are instant after SMS confirmation.
- Deposit caps help support responsible gambling habits.
- Safe, discreet, and ideal for mobile-first players.
- Some casinos offer special mobile-only bonuses.
Stretching £3 Phone Bill Deposits at the Gaming Tables
Stick to 1p or 2p fixed-odds scratchcards, 10p outside roulette bets or proprietary in-house slots with micro-line stakes. Table-game minimums (£5 blackjack) exceed the bankroll—so save those for bigger deposits.
