Did you play with the pin code of the sim? try inserting a diferent sim into your phone and if it works, then the problem is with the sim. you will then have to take the sim to your network provider

Does this error comes when you insert the sim in your phone?I guess the phone is locked with a particular network and you are trying to insert a different network.You need to unlock the phone.You can approach and specify the country,locked network.Based on the availability you will get the unlock code along with free unlock instructions for your Nokia 3250.

Whenever I try to use my Nokia E63 It says Sim card not valid? What do I do?


Reseat the sim card, if that does not work, try any other sim card and see if the phone reacts to it any differently, if this problem happens with only one sim card then either that sim card is broken / faulty or the phone may be locked to a specific network provider, in that case you would need to get the phone unlocked.
