Q: No signal iPhone 7 plus

It seems use of GPS is common among those suffering from this problem, but it may not be the only issue. I always have Pokémon Go running and it uses GPS as well.  With Voice over LTE shut off I did notice dropping from LTE to 3G a few times where it didn't with my iPhone 6. Haven't see the "No Signal"yet.

...since turning off Voice over LTE I meant.

Further experimenting...

with both voice over lte off and location services off, when it drops to no service it tends to eventually come back.

However.... despite saying 4-5 bars of LTE I cannot actually use any data. Safari just spins for example. After a few minutes of this it realizes nothing is happening and back to 'no service' we go!

Also interesting, the last time I came off the elevator it went to 5 bars of AT&T service, no LTE, no 4G /3G, just AT&T.  Maybe this is just a non-data connection? When I tried to hit a web page with Safari it told me right away, no internet connection.  After a few minutes of this it popped to LTE but then just spins when I try to use the connection.

in short, it's a mess. And I'm on AT&T though it seems most people here are on Verizon. 2nd phone.... hesitant to get another, but on the other hand, this one isn't usable at all.  And there must be some reason Apple is swapping them without hesitation.

Another person with same problem.  7+ 256KG on Verizon.  Got a new phone - didn't make a difference.  Put in my old SIM card from my previous iPhone - didn't make a difference.  Problems exists with Waze but also without.  Will turn off voice voice and data and just make it data on Enable LTE and then see what happens. 

Same trouble...att user in Maryland...iphone 7, 256G.  att guy felt it was hardware

issue with antenna, said others have had same complaint.  Apple genius bar

guy was all about software & cell towers.  Upgraded my software.  Didn't fix it.

Apple Store offered to switch me to a new 7, I decided to return the phone instead

on the 14 day warranty.  Very glad I did, now that I have read others' accounts

of a 2nd phone also having same trouble.

I write this from my trusty 5s, which is now back from retirement!

See my earlier post -- two posts up.  Same problem with new phone (iPhone 7+).  Did clean install and problem was still there. There with Waze and without.  Made Cellular Data Option for Enable LTE to be "Data".  Improved but the reception is still weaker and not the way it should be - or the way it was with my old iPhone 6.  Needs a fix.  Given that some people seem to have good luck with new phones, wondering whether that would be worth trying (again!).

Lucked out and got a replacement today. Did a restore from backup. So far so good. That was about 4 hours ago. We'll see how long it lasts.

Please report back on how it goes.  All too often people post here and then don't update.  Thanks!

Update from earlier. I said earlier when using waze for navigation I would get No Service, but I tested it multiple times,  when I use waze without the navigation turned on I never got no service. This would tell me it has something to do with using the gps. I hope that is a software fix as I have tried rebooting, popping out the SIM card and resetting my network settings. others ease try this and see if the same thing happens. I have a black 7 plus with Verizon

I'm having GPS issues with Waze too on my 7 plus on AT&T. I'm really hoping it can be fixed with a software update soon!

iPhone 7 256gb on Verizon. Same problem. Experienced it on a drive the Saturday after the release.  "No Service" 10-12 times on a 100 mile drive on Long Island in New York. Tech support guy already had a couple calls about it and suspected a defect. He said that we could go through all the possible solutions but in the end, he expects the phone would have to be replaced. So, Verizon sent me out a new one. But the new one had the same issue. I promptly marched into a (corporate) Verizon store today and returned it. I'm back to using my old 6. Serves me right for getting the newest iteration before all the bugs are worked out.

MY phone is on LTE data only and I turned off roaming as of yesterday. So far everything is working good. While using Waze, it showed "searching network" but my 7+ 256 verizon worked fine on my way home from work and to work this morning. It even worked while talking on the phone with the Waze app in use.  I downloaded 10.0.2 so maybe that helped? My wife just purchased her iPhone 7 and is going to use Waze today setup with data only LTEand roaming off as well. Hopefully hers works as designed also. Maybe we have a solution here...

I Have same issue with iphone7 AT&T 256gb silver. Worked for 24 hr when new. Then no service. Went to Apple Store and it started working in store when dead for 24 hr straight.  Got home and no service again. No reset, restore to factory, reseat sim, or aiplane mode switch would bring it back.  Apple replaced the phone as defective. Now the replacement is doing the same thing. It worked for 6 days before failure. Going back to Apple Store, but not happy!
