hi,
is there network service bar on your phone?
if no,check the antenna of the phone if it is properly fix, if not fix properly, then fix it properly.
if the problem continue go to your phone menu, go to setting and call setting go to bare calls.
if the calls are bad, you deactivate it.
if this still continue then you contact your local service provider.
thanks for using fixya.

definetely you have an antenna problem!

try restoring the phone in itunes.
