I just replaced my 4S battery myself. the issue I'm facing after doing so is to have my iPhone keep searching for the mobile network. Even after fixing the date & Time, and reseting the network setting the issue has not been solved yet.

Any idea what is the problem????

does it has anything to do with WIFI connectivity? my WIFI router has just gone out of order tonight :(

Anyone have any idea to retrieve the mobile network without having WIFI connected?

HELP ME PLEASE
