Answer to: Intermittent Cell Signal Issues Persisting After TroubleshootingHi, the problem is caused by the baseband IC chip. You can double check this by dialling *# 06# If the screen is blank then its this chip. If the IMEI comes up (it will only show when you have a connection to the network), then its this Baseband chip. Checking under general settings will always show the IMEI even if the baseband chip is faulty. The phone get bent a little in usage and back pockets, which breaks some of the solder connections under the chip. The only way to fix this is to remove the chip, clean all the old solder off, then reball/solder and refix the same chip which is married to the board. Trying to heat the chip and giving it a nudge will not work as you need to repair 2 specific solder points which will have already been cracked and damaged. This is a very skilled and specialised repair. Hope this helps. KH
