Hello can anyone could help me my nokia 3250 has no network coverage or no signal and if I search for network it will automatically restart the phone and if I am trying to call someone it will also restart. Please help me out how to solve this problem...

Try taking out the SIM for a few minutes and trying again.

If that fails, ring your network provider.

Or even change for a new SIM.

I have tried to remove the sim card and then I put it again bust still the same it has no network coverage. I have tried my sim card on other phone but it still working I think the problem is on my phone nokia 3250.

look to the phone setting...try call your service provider...
