I have similar issues with this on my iPhone 7. It loses LTE service randomly then it has to fall back on 3G after it reacquires a signal.
I've been having the same issue since Friday night on my 7 plus. Took it to Verizon yesterday and had the sim replaced but that didn't fix the problem. Called Apple, they had me do a factory restore with my mac (I think that's their solution for everything). I drove 45 minutes into New Jersey today and twice the phone switched to no service. I noticed it usually drops to no service or 3g when I'm moving in the car. Hopefully Verizon or Apple figures this out.
I experienced 3 dropped signals yesterday while driving in NJ as well. I was using Waze or Google maps when they happened. Had to go on Airplane mode for a few seconds and then back to get back onto LTE. Hope this gets resolved.
Chiming in here, I live in NYC market, having the same issues. I noticed just in general use my phone would goto 1x sometimes then to 3g and not go back to LTE. I would toggle airplane mode and be back on LTE. Yesterday I needed to use waze for some driving and I got no service issues having to toggle or reset the phone. This happened within NYC and then when I was in New jersey driving a long trip, same thing I ended up just turning off waze. There is certainly some software issues. I do not believe at this point swapping phones out will fix anything since I believe it is a software / radio issue.

Yeah this is the use case for me... pulling it out of my pocket, 4 or 5 bars, no data, then you see it jump to 1x and then to 3G, but not LTE. I have to flip to airplane mode and off again to get LTE back.I think it's anything that puts a data load on the phone. Happened to me every time I took my phone out of my pocket and either checked the forums or facebook.

https://forums.macrumors.com/thread...ff-airplane-mode.1998373/page-2#post-23510941I've noticed that whenever Waze or Google Maps is running the phone loses service every approximately 10min then goes back to normal after 1 min. I drove around NYC all day and noticed this disturbing pattern so I called Verizon and they had me reset network settings to no avail. Anyone else seeing this?
Just got off the phone with Apple's support and then Verizon's support. Apple person acted like they had not heard of the issue before. Verizon person was surprised but did some research and found others have reported it. Got the recommendation to reset network settings. Not sure what the resolution will be but I'm trying to do my part by reporting it!FWIW, both customer service people were ridiculously polite, so that was a welcome change!
VZW support just contacted me and had me turn off HD voice as a test. You may want to try the same. VZW "Check by going to Settings> Cellular > Cellular Data Options > Enable LTE. If it's turned on, it'll show as Voice & Data. Please change this to Data"
