iPhone se cellular signal drop

Hi, I have recently bought an iphone se second hand and it's warranty period is expired. This phone signal strength is always 3 bars at home so I can receive and make calls, send text etc.

But when I travel in bus or walking to office the signal drops to zero and then the signal never comes back even after restarting the device.

It only comes back if I swap the sim to another phone where it works great and after that I put the sim back to this phone.

I did everything network reset, ios restore, latest ios updates etc.

Any ideas what could be the issue?

The fuselage shell of the non-original plant can also cause the signal to drop, or is it good to check the antenna interface?If all of these are ruled out, that is why the motherboard signal amplifier is needed for maintenance.
