I wondered if any of you guys out there could help little me ?? Not knowing a huge amount about mobiles I purchased a 6230i from my next door neighbor but one It was locked to the O2 network (UK) I then paid to have a unlock code ( Didnt know about this site back then !!) anyway I managed to unlock the phone & it recognises the Orange sim that was put in there. How ever there is a but !! when the mobile is switched on it asks for a security code ... I have phoned up O2 who then told me to phone club Nokia ( which I then had to join ) Who informed me that the last owner must have put a lock on the phone so that it would only recognise the original sim I have asked her what the code is but she cant remember what she would have put on there... What if anything can I do ???? Any help would be appreciated
