I have iphone 6s which is out of warranty. It start showing no service i don’t know why i dont even drop it. I also contact apple they said it cant be repair you have to buy new and i almost try everything after everything I switch off my phone and leave it for 2 days and when I switch it on it got network and it start working fine but after 8 days its again start showing no service but when I switch it off for day it got network and it work fine for 1 or 2 days after that its start show no service . Can you help me what should i do to fix my iphone. Is it the antenna problem or any other hardware issue?
you could try replacing the antenna first if it doesnt help it could be an issue with the board. first off try and reset the network settings
