Hey all, I have finally received iPhone 7 Plus this Saturday after preordering it ages ago. Overall, super quick and nice camera. However... major issues with cellular. At my house in D.C. everything seemed okay, but the second I drove out to Maryland to my parents summer home in Lusby, issues all over. First, if I have LTE most of the time it isn't usable, nothing loads, even Speedtest displays an error. Other times, device gets stuck on Edge and even cycling the airplane mode won't fix it. When sim is first inserted, most of the time it is literally taking over 3 minutes to find service, other times gets stuck in No Service Mode. Mind you this happens in an area that gets 10-60mbps on T-Mobile and I have never even seen Edge at this house before. I have tried: 1) Activating New Sim. 2) Resetting and setting up as new. 3) Resetting Network Settings. 4) Using my Sim in another device (iPhone + S7 Edge) which my sim works great in. 5) Using another Sim in an iPhone which causes same issues. 6) Reinstalling iOS via iTunes. Conclusion: either a hardware or software bug. I called T-Mobile and they are sending a replacement iPhone. With backorders, it says that the estimated ship date is between 11/28-12/19. I have been reading around and it seems as if few Verizon users are having issues with LTE data, device dropping to 3G in strong LTE areas. Ive seen an article stating that T-Moile users are having issues as well, but nothing concrete. I know that something similar has happened with T-Mo and iOS 10 release, but I haven't found much on iPhone 7 and these issues. Does anybody have similar problems? Also, I made a Genius Bar appt for Tuesday, but according to apple.com they are out of iPhones in store. I know inventory for replacement is different, however it may also be the case. If this is a software thing, then it will be unlikely that replacement will do any good anyway. Thoughts?
