I have just bought a 3G on eBay UK (I live in the UK) and it is locked and two weeks old. I am happy to stay with 02 because they have great coverage where I live and places I need to travel to on business. Am I correct in thinking I need to buy a 3G SIM card from 02 and add the Web/WiFi bolt on? Will I need to get it unlocked? Basically I need an idiots guide to exactly what to do when I receive it please!
