Are you saying that someone removed the GSM IC off your phone?

no one removed the ic . it was removed automatically by falling on the floor from the roof. the screen and touch was shattered now i changed the screen portion with new. other things are intact.

SIMRAN, so the way I understand it, your GSM front end module is off. You can get it from here if you need a replacement. To replace it, I would possibly treat it like a reflow. also, have a look on here. I hope this helps, good luck.
