I recently bought a new iPhone 7 with no guarantee and the SIM card is unfortunately not read (SIM card is not defective) and the mobile phone does not activate a laptop, pc etc. I also do not have it
Does the device start at all? So do you come to the menu?
Yes, it still starts, but I only get to the point where it says to configure manually
And you won't get any further there? Does the display accept nothing?
Possibly. Otherwise check with the manufacturer to see if they can assess what's going on.
