I get an error message on my nokia 3310

[desiraja]

I switched my sim card and now when i dial numbers on both sim cards it says no network coverage?

Oh dear

Well, have you checked the Sim cards in other mobiles?

If they do work, then your phone is screwed. How did you unlock it? When did this error first occur (after doing what?)

Give us a bit more info

Cheers
