sim card registration faild

after following Jpp01UK's directions to unlock my nokia 6230 which worked fine. my phone is now excepting the sim card but sayin "sim card registration failed"
if anyone can help me on this it will be much appreciated

 

what sim is it? make sure your not trying to put a 3g sim in a 2g phone, it wont work

if the sim works in another phone that is unlocked, then try to unlock your phone using VERSION 5 of the codes i gave you

had this happen on a nokia 6600, said it was unlocked but would accept new sims, but it finally did after version 5 was input, apparently its a symbian phone thing. but yours isnt i dont think

but try CODE 5 anyway

let me know what sim it is etc, might help to narrow down the problem

 

just tried code 5 but there isn't any change
i am trying to put a 02 genie sim card into a t-mobile phone

these sims are crap people have loads of problems, contact o2 is my advice, sim updates may be needed

 

ok thanks for your help anyway very much appreciated

 

i have just tried a normal 02 pay as you go sim card in the phone and the same message has come up, would this be a problem with the phone?

 

o2 had a tendency to lock the sim card to the phone via the IMEI number many moons ago, dont think they do it now

try an orange sim in there or something

when you typed the codes in what i gave you did it say "sim restriction off"?

 

yeah sim restriction of was the message that came up when i entered the code.
