We no longer stock the O2 SIM or Credit - we instead recommend the 3UK Phone SIM as it is much better value for money.
THIS IS FOR CREDIT ONLY- see separate listing for the SIM.
If you already have an O2 SIM, and want to add credit, just add this product to your cart.
The credit is sent as a PIN via email within 12-24 hours (sometimes slightly longer on a weekend)
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.
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
You can get 50Mb of data a day for a £1, or you can opt to buy one of the great value data bolt-ons;
100MB = £3
500MB = £6
1GB = £10
