N70 Problem

[Parmesan]

Got a little problem with my N70, It seems to be stuck in offline mode, Now i didnt even know it had an offline mode, I have tried changing the profile to general or silent but it keeps saying insert sim card?

Anyone else had this problem and found a way to fix it?

Tried updating the software, that did nothing, have also tried my sim in other phones and it works fine. Have tried a couple of other peoples sims in the phone and they dont work either.

Will take it back to nokia and see what they have to say. Cheers for the help though.
