Hi,
If you haven't dropped the phone or got it wet then try turning the phone off then on again and see if it works.
If still not try removing and then reinserting the SIM card and see if it works now.
If it still no good try your SIM card in another network compatible phone and see if it works there OK. If it doesn't your SIM card may be faulty.
Try another network compatible SIM card in your phone and see if it works in your phone. If it doesn't then your phone's SIM card reader may be faulty.
