Web Top-Up

Anyone can now securely and simply Top-Up any O2 mobile phone through the web, 24 hours a day, seven days a week here at o2.co.uk

You can now top-up your own phone, top-up someone else’s phone or get them to top-up yours! And, as a thank you for using the new service we’ll even add 10% extra calltime to the phone you top-up the first time you successfully top-up this way.

Please note that the new service is now completely registration-free, so you’ll need to have your debit or credit card handy every time you go to top-up as you’ll be asked to enter your card details.

* This offer is only available the first time you complete a successful web Top-Up transaction using the new service. The amount of free calltime you're given will be calculated as 10 percent of your Top-Up amount. The free calltime will be credited to your phone within 24 hours of your successful web Top-Up.
