My blackberry says no signal

As far as I know.there are two possibilities to get this error..

1)Sim card not inserted properly:

Try to insert the sim properly..insert it at the desired position

2)Phone may be locked with a particular network:

If the phone is locked with a particular network then you need to unlock it.You can get the unlock service for your Blackberry 9360 Curve from either your network provider or third party unlocking service provider like, unBBlock.com and remove the network lock. Once unlocked it will work with other networks.

3)Sim Problem:

Mostly this won't be in your case because the sim had been working fine with your previous Nokia mobile and also the phone gives the same error message when you insert other sim cards.

4)Hardware Problem:

There might be some loose connection give it to a hardware service shop and check.

Don't use free codes. Several wrong codes may permanently damage the phone. For network unlocking solution you may consult with this webstore: www.guaranteedunlock.com
