Cellular Update Failed in iOS 12

I have had this problem after installing ios12. Been leasing with O2 and they can't do anything. after talking to Apple tech support I went to the local Apple Store and was told it is an emerging problem and basically my iphone7 plus is unrepairable. The update has caused a problem with the modular modem and I need a new phone. I've raised a complaint with apple as I say it's their update that has caused the fault. Can't access any mobile data, texts or calls etc.

Apple has extended the warranty to cover this problem with the Iphone 7 to a total of 3 years. Take it to an Apple Authorized Repair center where they will evaluate it for eligibility. If it is due to their defective hardware, they will replace the logic board to repair your phone. That is my understanding, and how it worked for me.

Had the same problem with my 7 after updating to iOS 12... just updated to iOS12.1.2 and I’m seeing the return of the IMEI and the ‘No Sim’ signal as oppose to the ‘No Service’ and errors... I’ll see if the problem is fixed now or if I lose the IMEI again...

I have deselected and reselected the network, removed and replaced the SIM card, powered off and restarted the phone reset the network settings.... everything I could find on the net. I have the Vodafone App and have been through their customer service chat service, and when their consultant tried to contact me by SMS it does not come through, when the try to call As the screens switch over from WiFi to cell Mine is blocked with an error message

What is telling you that you need to update, and were you ever a part of the iOS beta program.

See this about the iPhone 7 issue, and see if your device meets the eligibility for the program. iPhone 7 Repair Program for "No Service" Issues - Apple Support

Start by checking to see if your carrier has a local network outage. Or this site: https://downdetector.com/

Thank you but it is the Vodafone network in The Hague, The Netherlands and has no outage at the moment .

Your phone is broken. The only solution is to contact Apple Support to arrange for a repair. Contact Apple Support
