I tried to unlock me Nokia 6230 from t-mobile and now i cannot get any signal at all and an error message comes up saying
'Sim Card Registration Failed'

Anybody know how to fix this?
If not, how to I lock the phone so its back to the way it was locked to t-mobile?

Thank you,
Burnttime

'Sim Card Registration Failed' normally means the sim is inactive, expired or you entered "a" or some unlock codes into the phone with this sim in the phone and burned it. Locking the phone back is nearly impossible unless it's done with AT commands from a computer which is very hard to do and not recommended. The phone being unlocked isn't the problem, I would say the sim is. Try a new sim or a friends sim and it should show to be working fine. This is if it's definately unlocked.
