""No Service" after battery change on iPhone 5"에 답변It could be a sim issue. I got that twice, and both times my carrier had to change the sim.
""No Service" after battery change on iPhone 5"에 답변When I replaced my screen on myiPhone 5 the phone was constantly searching for network. I had reset network settings and the phone started working (receiving calls, messages etc) but it was still saying searching at the top. I then connected the phone to wifi, did the reset network settings and it fixed everything. The signal bar and stuff came back.
