    Today I went to the Syracuse Verizon store located at the mall and they were not helpful at all besides pointing me to the Apple store.  They were not concerned at all with helping me troubleshoot the LTE signal issue and would not replace the Verizon SIM card.


    I went to the Apple Store and was amazed by how helpful they were.  They listened to me state the problem and asked relevant questions to confirm what troubleshooting steps had already been taken.  They agreed that replacing the phone would help me get closer to nailing down the problem.  If I can say anything positive about this ordeal so far it's how extremely professional and helpful Apple was during my first experience at their store.  I felt like the service received justified the cost of ownership for their product.


    Now to the bad news.  Replacing the iPhone made no difference in the LTE issue I have been experiencing.  The LTE worked for a few hours and then like before it dropped the upload.  The only fix is toggling airplane mode and once the phone grabs LTE again it works fine for a hour or more then reverts back to failure (no upload, FaceTime etc)


    I'm in the process of grabbing before, during and after screen caps of signal levels, speed tests and FaceTime attempts.  To be clear this is issue is not just with FaceTime but its how I've been noticing the problem because I use that app often and it requires upload. 


    The signal level at my home is approx -85 which should not cause an issue.  The signal strength indicator never dips below 4 bars on LTE and it doesn't cycle to 3G so the issue is not with terrible signal strength as it appears some people are experiencing.  I'd like to in invite people into this thread who are experiencing this specific issue.

    Sounds like you have a bum VZW store but a really good Apple store. The Apple store near me was terrible when I went there.


    My VZW store had no problem swapping my nano SIM when I told them the problems I was having.  Given you already swapped the phone, i would highly suggest a nano SIM next to rule that out.  I had really weird behavior until i swapped my SIM, now my primary problem is just low signal strength and poor performance across VZW's network.

    I live in Syracuse as well and I have been experiencing the same issue. I have tried everything I can do without having to visit a store, but I guess I'll have to resort to doing so.

  • Tomcali Level 1 Level 1

    Now that the phone has been swapped out it certainly lessens the chance of a hardware issue but I'm not ruling it out.  If a sim swap doesn't fix the problem then Ill be running out of ways I can troubleshoot this issue and I'm fearing ill be stuck between two companies that claim the other is at fault.  I'll report back once the sim swap is done.


    Pete, how's the other thread coming along?  If I can't fix my specific issue here ill condense my posts and merge into the larger thread if that would be more useful.

  • Pete boston Level 1 Level 1

    No real conclusion from the other thread yet. At this point I believe 75% of my problems are VZW's and the other 25% are Apple's.  VZW has very poor LTE signal strength even with non-iPhone 5 devices throughout MA and NYC from my testing, the other 25% is that the iPhone 5 seems to handle low signal strength LTE worse than the Galaxy S III.

    Hey guys, I have this problem too, and not surprisingly, I also live in WNY. I live in Buffalo and work in Rochester, and I find that when I'm driving back and forth, LTE tends to hang when I switch from 3G to LTE and back again. Like most of you, I just turn airplane mode on and off and then it's good... until I switch networks again. I also sometimes experience the same thing when switching from WiFi to LTE. I'm on Verizon, so I'm guessing it's a problem with them.


    Let me know if anything changes or updates!

  • tcaputo Level 1 Level 1

    I travel all over the country and I live in Syracuse. I was in Orlando, Tampa, Sarasota FL at the beginning of the week and my Iphone 5 and had no LTE issues at all. Boston on Thursday and no problems there. Here in Syracuse same LTE problems you all have been experiencing. I would say its a network problem not the phone. If I do a hard reset it fixes the problem short term. Hope this helps.

    I'm having this problem to. I'm in Philadelphia. It seems that when you use the phone for over a minute and come back to LTE something weird happens. I can surf the web on some sites using LTE but if i go to the itunes app or the app store or try to facetime and send imessages, they wont send, Facetime wont work or the app stores won't connect.Putting the phone on airplane mode and then off everything works on LTE again. I replaced the phone but it also does the same thing. It only happens if you make a voice call. It seems like that's the only time.

  • modernistarchitect Level 1 Level 1

    Believe it or not, I think I might have figured something out. in Settings > General > Cellular > Roaming, there's a setting for International CDMA. Though the instruction below says to turn off when roaming internationally, I wonder if there's some setting that has an effect on the way that towers hand off the LTE to 3G signal and back again. I turned the setting to OFF, and my LTE to 3G switch seems to be much, much better. Might be worth a try to see if it works for all of you.



  • Pete boston Level 1 Level 1

    Thanks for the suggestion. I have only tried it for 5m so far, but no noticeable change yet. I am in a "fringe" [VZW "strong LTE"] location and my phone sat in "o" state for at least 2 or 3 minutes prior to going to 3G, and now is back to "o" again

  • Tomcali Level 1 Level 1

    I tried turning off international CDMA like modern mentioned above and 12hrs in everything appears to be working fine.  Lets hope you just found a quick fix!  Also thanks to everyone else for contributing their info so we can confirm that at least in NY this a an issue.  I'll be continuing to test the method above for a day or two before reporting back.

  • johnsonrod27 Level 1 Level 1

    same issues here 30 mins outside philly. airplane mode toggle works but is annoying, tried the international roaming thing..  well see what happens

  • Tomcali Level 1 Level 1

    Unfortunately toggling international cmda doesn't change this issue.  I'm back to where I started with LTE showing 4-5bars but being unable to upload which prevents sending dating from any app on the phone.




    Just got off the phone with Verizon Tech support.  They agreed that the sim card should be replaced as a troubleshooting step considering the work I have already done.  I should get the sim card NLT 17OCT.  I'll do the sim card swap and post any progress.

  • Allenpf Level 1 Level 1

    Hello again,  Cooleyrobb above might be onto something.  I have tested his theory, that it occurs after a voice call, since I read his post and it appears accurate.  If you reset your data connection, it seems to work until you connect via a voice call.  After the voice call, the data connection looses the upload speed. I reported this to Verizon, who told me that my trouble ticket has been escalated and remains open (12 days now).

    Count me in as another to have this issue. I'm in PA, but northeast of Philly. I notice a lot of replies are showing locations in the northeast, so I'm beginning to wonder if this is an Apple issue or a Verizon issue. This issue only just started effecting my phone last Wednesday, my first two weeks with the phone prior were without issue. The issue for me happens when I either end a call and connect to LTE or when I leave a WiFi network for LTE. The only thing that helps is either doing a hard reset or resetting network settings. Apple is sending me a replacement device, but I am not hopeful that it is hardware. I hope this gets fixed soon, as if I forget about this my battery drains really fast due to the weather widget trying to update and not having a connection.
