I have been plagued with no service now on my iPhone 7 Plus 256GB since Saturday. Every now and then when I travel in the car for some distance it jumps up to 5 bars on 4G and my Notifications start alerting me of messages etc but if I then try and use the network for a phone call or browse the Internet I have nothing!!! Call Failed or Can't display this page etc. Things I have tried to fix the issue with no success: Powering off the device and turning it back on. Soft reset device power button & volume down. Removing the sim card and putting it back in. Reset network settings. Upgrade to iOS 10.0.2 Fresh Install Upgrade to iOS 10.1 Beta 1 Fresh Install I feel my only option now is to goto my local Apple Store with the device to at least make them aware of my issue just incase I should need it replaced. There seems to be plenty of people in the same boat as me going by the posts on Facebook & Twitter. If you're affected by this please list your model, capacity and network below as well as the iOS version.
