iOS 10/iPhone 7+ constantly dropping service..

Enthusiast - Level 2

just completed 200-mile trip, all interstate with 95% LTE coverage.  iPhone 7+ would drop service every few minutes/miles (switching between towers maybe?).  Other devices on iOS 9. (6s, 6+) as well as MiFi were able to maintain continuous service.   Comparing coverage when service would drop showed iOS 9 maintained 3 bars, so not spotty coverage area.  Is there any way VZW could troubleshoot what happened and how to fix?  Has to be an iOS 10 or iPhone 7 issue...

I found an interesting way to try and reinstall the update by going to https://ipsw.me/. This site contains the downloadable file for the ios update 10.3.3. What I did was download the file then have iTunes restore my iphone with the new fresh download. Here are the steps:

  1. Download from the site ​https://ipsw.me/ . Be sure to look at your phones model number in the back to see if it is a global or gsm phone because you have to download the right file.
  2. Turn off "find my iphone" in settings (icloud)
  3. Sync your iPhone into iTunes.
  4. Before clicking iPhone restore, push and hold alt/ option (mac) or alt (windows) then the iPhone restore to open the systems menu and find the download file of the ios update and click ok.
  5. Follow the prompts and it will erase the phone and reinstall the update to the phone.

In theory we are just reinstalling this because possibly the update might of not installed incorrectly but if it does not work, you can follow the same method above to downgrade back to 10.3.2 if you like, good luck!

UPDATE: It has been 2 days now and this method has actually stopped the dropped services, although I still have once in a while get drop bars, I still get service. This method purpose is to try reinstalling the update because it seems that installing it though your phone or though iTunes caused a improper install of the update, but I have to say that downloading the file from the site actually fixed the dropped service! Try It!!!

I to am having this problem and I thought it was just me.   I use WAZE a lot for work and I just kept dropping GPS.  and frequently got no service in major markets.   I traveled from Harrisburg to Baltimore on 83S and on 695 E & W around Baltimore and was dropping service frequently.   Very frustrating.  I pulled over and called Verizon and the rep. said it was a know trouble area.  And that proved to me that he didn't know what he was talking about, hello - BALTIMORE 695 and 83 are major routes with fantastic coverage albeit no from an iPhone 7 plus.   So I just gave up on Verizon and decided to google it later...and here I am, glad to know that it wasn't just me.  But sad that this is happening and they don't even know what's causing it.   Hopefully they will be able to fix.   I switched to iPhone from my Samsung Note 7, so one might conclude I only have bad luck.   Thinking about just going to back to the Note 5 until they get this fixed.   Also, why the hell doesn't my iPhone 7 plus play nice with my brand new Subaru.   Just saying.   Figure it out Verizon and Apple!!!!

I can tell we have our work cut out for us. Swalljo. After all we don’t want you to leave over this. If performing a "Reset All Settings" (https://www.verizonwireless.com/support/knowledge-base-207095/ ) does not solve this for you, as Apple suggests here: https://support.apple.com/en-us/HT201415 , we recommend for the device to undergo a restore.

Hi,

When doing a full-restore, will we need set up the phone as new or restore as a backup?

Hi DG971 ​!

I can gladly clarify. In an effort to retain your device content, please restore from backup Perform a Device Restore via iTunes - Apple iPhone 7 / 7 Plus | Verizon Wireless

I am on my second iPhone 7.  I have spent hours with VZW tech support.  We have reset everything and restored the phone multiple times, confirmed that the latest carrier upgrade is installed, tried 10.0.3 and 10.1 - everything and more.  The iPhone  7 simply lags at least one bar behind my wife's iPhone 6 at best and gets "no service" where I've never experienced that before.  I'm really at my wits' end...I need a phone that works as a cellphone, not a mini wifi mobile.

I don't know if this will help anyone else, but it made a huge difference in my iPhone 7 and it cost nothing to try. 

I replaced the sim card in my phone with an absolutely new, virgin sim card from the local VZW store.  For some crazy reason, it took over an hour for the phone, the sim card and the network to talk to each other, but since I replaced the sim card the phone is no longer deaf.  It does seem to be getting  reception roughly on par with my wife's iPhone 6, which is fine.

I can't guarantee this will work for others, but it made a big difference for me - good luck.

I have been having connectivity issues with my iPhone 6s ever since the last 9.3.x IOS release. I actually upgraded to IOS 10.0.2 in hopes it would resolve my issues. My signal strength indicator is constantly changing, sometimes zero bars, no service, 5 bars, etc... which is also draining my battery really fast. I can't make or receive calls or SMS texting. I want to roll back to an earlier IOS 9.3.2 that was working fine but apparently Apple needs to be signing it which they are not anymore. My wife's iPhone 6s is not having any issues with the same exact hardware and software configuration. Verizon service won't give me any details when I call them which I have done many times now. They only said there is a big network issue. I am seriously considering cancelling my service at this point since Verizon has breached it. If there is a major issue with the IOS they should tell us and when it is expected to be fixed. I basically don't have a phone right now. An extremely frustrated customer.

Hello,

Have you updated your iPhone to iOS 10.1? It's available now. Settings-General-Software Update

I have updated the IOS software. Ths was supposed to fix connectivity issues and it was totally useless. I have been getting many dropped calls in a strong signal area. In some instances I am seeing "NO SERVICE".  Never had this issue with my IPhone 6s. It's time for Verizon and Apple to step up to the plate and resolve this ongoing problem.

As as mentioned by other people in the community, Verizon is only interested in the area or zip code you are having problems in and don't seem to get it that it's a network or phone problem.

Try doing this. Back up your information through iTunes or iCloud. After that's done, Erase and Reset All settings. What happens there might be a bug in the software itself and the backup might be corrupted. I was having problems before when I had the iPhone 6s last year. I did a back up and erase everything on my phone. I set it up as brand new iPhone. No backup from the cloud. After I got to Welcome to iPhone, my reception was a lot better. I was having problems at work mostly and I was getting my LTE working. Sometimes it goes away because I work for the government and close to the airport so signals are very weak but it was a lot better than getting no service, 1X or a lot of the times 3G but not LTE.

When I tried using the back up from the iCloud so I can see if I get the same results. Unfortunately the problems came back. So just try not restoring from back up. Choose Set as a new iPhone.

See if that works for you.

10.0.3 is only addressed to iPhone 7 & iPhone 7 Plus owners.

I don't know about iPhone 6s, but somebody on the thread said 10.1 fixes the issues on their  connectivity issues, then my best suggestion is to wait until Apple release the iOS 10.1 later this month. I'm very sorry to hear you guys are having connectivity issues on your iPhone 6s. Again 10.0.3 is only addressed to iPhone 7 & 7 Plus owners.

Yeah, there is no 10.0.3 update.  Beta 10.1 resolves the carrier issues on iPhone 6s but not all users know how to enroll and many more don't know how to get off it once on it.

Luckily my 7 Plus is working perfect but here is the fix for those with problems.........Apple releases iOS 10.0.3, fixing Verizon LTE issues on iPhone 7 & 7 Plus

In this Verizon forum someone reporting doing a General->Reset->Reset All Settings ( *not* "Erase All Contents and Settings") to fix the issue of LTE dropping out to 3G or 1x on iPhone 7, even in strong signal strength areas.

I tried this and, so far, it's looking like it might have worked.   The issue might be caused by people restoring their backups from earlier phones to their iPhone 7 models.   "Reset All Settings" puts your iPhone 7 into the default settings configuration without affecting your installs apps, etc.     You do need to redo your Touch ID and re-sign into iCloud, resign into Messages and re-configure some settings.

I actually have not had the Verizon signal dropping or issues on both me and my wife's iPhone. What I have had is the crackling and hissing/buzzing sound on the back of my iPhone near the Apple logo. Anyone else have this problem with their iPhone 7+? Try turning on a youtube video and turn the sound off. While the video is playing, listen to the back of your iphone to the right of the apple logo. We even had my wife's swapped out at the Apple store and the new one does the same thing. Is this normal?

Also having the issue. iOS 10 update significantly depreciated reception ability. Dropping words, whole calls. I used to be able to call in a darn near Faraday Cage. Now, out in the open on a clear day is spotty at best.
