Losing network connection after some time.

[its_celesto]

Guys my phone is finding it difficult to consistently maintain network connection. When i try to call someone, it shows not registered on network. When someone tries to call me, it shows that i am out of coverage area or switched off. I put this sim in old phone and found that it works well. If anyone has any solution to this please do tell.

Try to reset your phone once...or else run diagnosis once
