For some reason, my iPhone 11 doesn't catch cellular communication

[Guest /u/Own_Zone_3240]

After I changed the power button in my iPhone, along with the flashlight and microphone, my cellular connection stopped working the next day, I think it's some kind of software error because I disassembled and assembled the iPhone I carefully and did not damage anything. Can you give solutions to this problem?
