After update to iOs 15.7.8, iPhone 7 refuses to activate
The iPhone 7 says "Activation not possible" (Translation from the German prompt "Aktivieren nicht möglich") and then refers to the Apple support homepage in general, a call to the Hotline could not help to solve the issue.
It started after the update to 15.7.8 with not finding the mobile network at all.
I already went through all the usual steps, starting with erasing the network connections up to completely wiping the phone and trying to reinstall an older backup.
Trying to install the backup after wiping the phone completely always ends with the above quoted prompt "Activation not possible" .
It seems like the update to 15.7.8 completely does not work with the iPhone 7 :-((
It is quite annoying, that I am also not able to reinstall the older iOS version that worked perfectly fine until the day before yesterday, when I decided to install the update.
PLEASE HELP!!!!
