iPhone 6 says " No service " or "searching"

I can not get my phone to get any cellular signal. I have tried everything on the software side of things and I mean everything. I know this is a hardware issue because for a while If I just gave my phone a bump, the cellular connection would come back on and I would have service. I dove into the phone and I disconnected all the cables that plugs into the logic board and even cleaned the logic board. I connected everything back on, still no service. I need some help and answers on what I should do to get this working on my own. It's got to be something simple. is it a simple process to replace the cellular antenna and if so where can I purchase? Could it be the RF antenna switch ?

Check the date and time. If the date and time are off, it'll cause this issue. I fixed an iPhone 5s that was set to 2027 that was constantly searching. I hope this helps.

Is there any update on this issue? I have the same problem and I know the problem is on the motherboard. It was bent before and probably the solder underneath one of the chip is not connected. Is anybody knows which chip is responsible for carrier network?
