Could you please try inserting another SIM card to see if the problem persist? This to rule out if the issue is with the SIM or the phone itself.

yes,i tried many SIM card and i tried factory reset.problem still here.

In that case I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.
