  • If you’re topping up either by phone, by text or online, you’ll normally need a UK-registered credit card or debit card. Mastercard and Visa are universally accepted, with support for American Express being limited to some networks. Some, but not all, mobile networks will allow you to top-up using a card that’s registered outside the UK.
  • If you’re topping up with an electronic top-up card or top-up voucher, you can normally go to any retailer displaying the green top-up logo. This will include most UK supermarkets and convenience stores. You can also top-up at mobile phone stores and at your nearest branch of the Post Office. This is the best way of topping-up if you’d like to top-up with cash.
  • If you’re topping up at a cashpoint (ATM), you’ll need a UK-registered debit card or cash card. You should check to see whether your mobile network will accept a card from your bank (some mobile networks will only accept a card from certain banks).

  • Looks like Asda Mobile top up by text is now minimum £5. I tried today & got a reply saying please choose an amount from £5.

    • welcometopoland replied:

      Yep. Greed everywhere. If you just want to make 1-2 calls a month, you must waste 5 quid on any network. They are pushing people onto the monthly plans.

    Virgin pay as you go have told me that in January 2022 they will cease to have Pay as go . Unfortunately my phone is locked to Virgin , so I either get it unlocked or buy another phone . For sure it won’t be anything connected to Virgin ..//

  • Hi Ken
    Thanks for a fantastically-informative web site.
    Re Asda Mobile, I’ve just registered a card with a £1 top up. So in theory, I suppose you could keep registering new cards to do £1 top-ups. Lot of hassle, though, of course!

    • Further development. If you actually call 2732 and speak to an agent, it IS POSSIBLE to top up by £1 on an already registered card. I’ve just done it. 🙂
