iPhone 7 Searching for network or no service
Hello,
I'm facing a problem with my new iPhone 7 A1660 model which it is not working on some sim cards. Knowing that the phone is originally sold unlocked from Apple.
The same sim card which is not working on my new iPhone7 is working on my old iPhone6 and friends's iPhone 7 A1778 model and other devices smoothly.
Noting that I tried restore, setup as new, restore from recovery mode.
Anyone can help?
iPhone 7, iOS 10.1.1, null
