To update:
iPhone 7+ 128GB Black w/ Verizon. NYC based (Brooklyn & Queens)....
As mentioned before, same issue occurs as all is reporting. No service, mainly while being out and about. The problem happens with VoLTE turned on (HD Calling) on the phone itself. Right now it's off on the phone, still on my account on the network! Not something I am fond of doing, as I've grown accustomed to simultaneously using phone/data.
It's mainly while simultaneously using Waze. I do not use other car navi apps. Now there was mention about GPS being the common denominator as well as VoLTE. To add, I don't know how GPS functionality would be on an app like Waze vs Map My Ride/Walk/Run etc. I use Map my Ride for 1 Hr+ and 15+ miles at a time with no disruption in service. The functionality of Map my ride is to record bike rides, not direct you. GPS technology is not my speciality, so maybe someone can clarify the difference between the two apps?
I also would like to add, that Apple as well as Verizon both advertise faster network and internet. Both wifi is no better, and Verizon's advanced LTE feels non-existent. This is an on going issue now for 14 days, nothings changed.
I wiped the phone clean, and I am not swapping the device if everyone who has done so is reporting no changes. Has anyone heard positive acknowledgement from Apple or Verizon? I am still awaiting Apple Care to call me back for a few days.
