Hey guys, I got a defect iPhone from a friend that I want to repair. The activations fails because it needs a sim card for that. It doesn’t matter if I put it in or not, it’s always searching for service. The Wifi is fine. The sim card works with other devices. I tried calling an emergency number for testing, the call instantly fails. That’s why I think the antenna is broken. I don’t think that it has a problem with reading the sim card as emergency calls should work without one. I went looking for a GSM antenna, but I was only able to find Wifi antenna parts. I hope you guys can tell me which part I need and if the problem might be something different (software->new motherboard maybe?) Thank you in advance!
This is a board issue, not the antenna. Usually it’s the transceiver or the front amps. If you go to settings-general-about and find that the IMEI/MEID not displaying, then it is a baseband chip issue.
