Ello boyz. I dont kno all that much about phones so I might be being a thicko here. I just got an 02 genie sim pay as u talk, pay £10 monthly (300 free txts a month monkey business). I came from a virgin sim (Pay as you go) and everythin was gd, reception bob on etc. Whacked new 02 sim in, and as soon as my phone fires up, a error appears saying 'SIM card registration failed', all my contacts are there and stuff cos I copied them but I have no reception whatsoever to activate my account. Do I have to put £10 on for all this to work properly? Any ideas? Ta. Edit: all I want to do is activate my sim card by calling a FREE number.
