Q: No signal iPhone 7 plus

exchange phone from apple ,it's the best way to did with that .there's a lot people do that

Have the same exact issue: iPhone 7 plus 256gb Verizon black. Preordered the phone got it on September 21st and after a few days no service drops to 3G and stays there until network reset or airplane mode toggle. Went to Verizon on the 23rd got a new SIM card and after a few hours the problem came back. Next day went to Apple told them about the problem they did a device swap which had to be ordered because there was no stock and on the 27th I got the replacement phone first day it was completely fine but the second day all the problems came back this time the phone has a hissing sound as well.. so on September 30th brought the phone back to apple along with the box and they said they can get a me another replacement and I declined it not knowing if its refurbished or not and asked for a refund but the genius didn't want to refund since the serial number is different than the box. Luckily i chatted with Apple the day before and had the email and talked to the manager and finally returned the device. Back to my iPhone 6s now and no problems with service even with VoLTE on. Miss the iPhone 7 plus size and stereo speakers but I'll wait until all the bugs and hardware issues are fixed before I order again!

I have this problem on my iPhone 7 (Verizon) and its really irritating and I almost got lost somewhere in Cleveland because of it.

Per the poster on this thread I changed voice over LTE to "Data only" and it seems to have resolved the problem.

Well, the problem isn't actually resolved but its a work-around that works, at least for me.

Still having the same issue with 4g going off and not coming back , the turning carrier from auto did

improve it slightl.

Guess we will have to wait for the next software update to see if it corrects these issues.

Update: It's been two weeks now since I first reported this to Apple. I have sent Apple the cellular logs that captured activity for 48 hours. They also took a diagnostic report that was sent directly from my phone. I've reset to factory new settings, swapped two SIM cards and it's still happening. Just today I was asked by their engineering team to swap my SIM with another SIM that is also active on Verizon (I used my the one from my wife's iPhone 6s) and the problem still occurred.

Judging from this forum (and others), many people are experiencing the same problem, but Apple still hasn't nailed down the cause -- or hasn't revealed a solution to their AppleCare team. Honestly, I don't know how widespread the issue is, but I would strongly suggest calling AppleCare if you're experiencing the problem so they can get a good idea of how many others it's affecting. Is it hundreds of people, or thousands? I have no idea.

For now, on drives where I need GPS, I've changed the LTE setting to Data Only and it seems to temporarily resolve the problem.

I have an iPhone 7+ With Spint and have started to have spontaneous signal strength drops and inability to make even local calls. I had to restart my phone but I still only have 2 bars. My wifes iPhone 6+ at least has 3-4 bars. Anyone else on Sprint having issues similar to Verizons.

I am on my 3rd iPhone 7 with my fingers crossed.  So far, an hour in it is still showing lte service. I am on AT&T and since day one have been loosing service and only seeing the No Service indicator. Once in a while the phone would perk up and show either 4G with Five empty circles, or full bars LTE for about 20 min but would still not pass tragic to and from the internet.

Apple replaced the first, launch day phone and the second one started the same thing after only a few hours.

Just got back from my 4th Apple Store visit and they gave me another new phone and so far so good.  The Genius said it is a known issue that they are working on a software update to fix.

My problem never went away, even with LTE on data mode, off or voice and data.

One thing I have thought about is each phone came with iOS 10.0 installed and soon after testing and setting it up, I updated it to 10.0.2. On a hunch, this time I left it at 10.0. And so far so good.

I hope this third phone is either a better hardware, or keeping it on 10.0 will solve it until they can release 10.0.3 to fix it for good.

So it is not just Verizon, but also AT&T that is effected.  Also the mentioned temporary work around of turning off LTE voice did not fix it for me.

Definitely is a wide spread as we have same problems here in uk , already saw a similar report from Australia too, seems like many if not all of the first production are affected. If software update fix it will be happy days but if it's a hardware issue with the antenna or Intel chip inside than recall is need it. I am sure that some users will never find out that their phone has this problems but for the average or heavy users it's a serious trouble. Went to Apple Store in London talked to some of the guys there and they knew nothing about it.

Having the exact same problem in NYC area-- for me toggling airplane mode doesn't help, have to restart phone.

Same problem in Pittsburgh, Pa. iPhone 7 plus 128gb Verizon.  Phone shows no signal.  Will not find a signal unless I shut it off and turn it back on.  Called Verizon they suggested turning lte to data only. The problem is that once you do that you can no longer talk and surf at the same time.  Verizon sent the issue to their tech people to work on. I considered replacing the phone but there are non in stock locally.

Following up: iPhone 7+ 128 Verizon. NYC area.

New Waze update for iOS didn't resolve the glitch when VoLTE was on. Phone went to no service as  previously mentioned. The one thing I do notice, when in no service, when you're in settings main screen, where it has shortcuts for cellular wifi etc. there is no option to manually select a network. I know in the past on my 6+ on Verizon if I legitly lost service for being In the middle of the woods upstate ny, the network selection option showed. I haven't traveled yet with my 7 to verify if this is a removed feature or part of the bug. I Don't think the phone even knows it's in no service

Just a follow up.  I picked up my 3rd 7+ on Sunday. No problems all week (so far).

I've been in dead zones where both my 7+ and 6+ dropped to no service, and it came back right away when back in signal area. In fact the 7+ came back faster than the 6+.

So maybe the 3rd one doesn't have the issue?

One thing I did do different this time around. I did NOT restore from backup. I don't really know what all Apple sweeps up in a backup, but it took 1-4 hours to accomplish on my first 2 7+'s. This does not count restoring actual apps.  I've had this same backup set going back to my 4.  So I thought, lets try a clean setup and see what happens.

So far so good.

Now...BluTooth to my car? Completely destroyed and unusable now...

Same problem with my Verizon iPhone 7 128 GB in Silver.

Keeps dropping to "No Service" any time signal is now and only way to bring it back is to re-boot the phone.  It doesn't help that I live in an area with 1 to 2 bars of service and I rely on WiFi Calling when at home.  I Turn on Waze to download directions when I leave the house and then No Service as soon as I drive down my street and onto the highway.  No Service and NO GPS.

Experienced the same issue while playing Pokemon Go.

My iPhone 6 running iOs 10.0.2 did not have any of these issues.  My iPad Air running iOs 10.0.2 also on Verizon has been consistently been 1 or 2 bars stronger in many areas.  The iPad maintains service while  No Service continues to show in my new iPhone 7.

I swapped out the SIM card with the one that was in my iPhone 6 and am hoping for the best.

Exact same problem.  3rd time factory defaulting the phone, only way to get it to work again.   7+ 32gb Verizon version running the 10.1 beta.  Guess I will Android it for a while

Well an update... I updated to 10.1 public beta 2 with it in it's not working mode and it activated and is working again.  Some symptoms when this happens, my phone number is no longer displayed at the top of the contacts, imessage still works on wifi, settings, about Network shows None, ICCC will say no sim but when I eject the sim it will have the No Sim popup.  Right now it's working.  If I did not know better it seems more like an activation/sim rejection error.
