Iphone 7 model MNCN2J/A Cannot make or recieve phone calls message without update
My Iphone is working normally then this message turns up on the screen every moth or so -AN update is required to use mobile data on this iphone -mobile update failed your iphone cannot make or receive calls or access mobile data until it has been updated. So basically the phone becomes unless out of the blue until it is updated. In an emergency a person could die from not being able to call emergency services Apple could face a class action over this issue that needs to be resolves as quickly as possible.I rang Apple support they had never heard of that problem before and the support person said you should be able to use the phone for calls and text whether up to date or not never had this problem with any other phone before.
