Experiencing significant issues after the iOS 10 update. Ive lost signals strength in several areas, and the phone will get stuck in No Servic. Rebooting the phone helps temporaril. I see it go from late to 4g to e then to no service, then stay as no service until I reboot. Resett all networks settings does not fix the issue.

I Spoke without T-Mobile (USA) about the issue. They said others have reported the same problem but no resolution has been found.

this is for iPhone 6.
