We no longer stock the O2 SIM or Credit - we instead recommend the 3UK Phone SIM as it is much better value for money.

GETTING CREDIT
dataGO.co can sell you credit you add to your account.
This is only if you have bought an O2 SIM from us -this normally requires a UK credit card.
Just purchase one of the O2 credit vouchers here. We will then email you the top-up voucher codes within 24 hours. You then need to put the O2 SIM into your phone, dial 4444 and follow the prompts to top-up using the voucher.
You can also buy top-up vouchers from O2 shops and convenience stores around the UK.
The main product information page for the O2 SIM is here and there is also a number of FAQs answered here.
There are two top-up amounts.
£10 = 75 UK mins, 500 UK texts, 100MB UK web
£20 = 250 UK mins, 2500 UK texts, 250MB UK web
And the longer you're with O2, the better it gets- they double the amounts included with the tariff top-ups if you stay with them for three months.
£10 tariff – Text GO10 to 21300
£20 tariff – Text GO20 to 21300
Now with extra data: get an extra 150MB when you top up £10 or 250MB when you top up £20
