Q: LTE is not working on iPhone 6 plus

i just got the iPhone 6 plus and it seems like it's not connecting to LTE.  I only see 4G icon showing even though my daughter's iPhone 5 is displaying LTE on her phone. Is this a carrier issue or the iPhone?

iPhone 6 Plus, iOS 8

    I had this same issue last weekend and tried all the standard resets and suggestions. I finally went to the AT&T store and rather than wait 2 hours for tech support, they just gave me a new SIM card and told me to go home and call in to get my phone switched over to that one. Took a 5 minute phone call and LTE was working...

    Had my iPhone exchanged at Apple today because of this issue, reception is the same. It is safe to eliminate the phone as the root of the problem. Verizon techs are investigating.

    So, you do not have hd calling enabled.  How does someone know if there phone is enabled with hd calling?

    The HD calling feature is enable by Verizon by default. It is not available in all areas, as it is still in early beta. To disable the feature you need to contact them. However, I am under the impression that it is not possible to disable that feature without disabling LTE.

    I am having the same issues, I plan on going to the AT&T Store today to do the same process you did.  Thanks for the info!

     

    Question:  Did/does your 4G/LTE drop randomly while driving down the freeway? And the only way to get data back is to switch on airplane mode for a few seconds, then switch it back off?  Thanks!

    Yes, I experienced this problem. (see my previous post in this thread)

    Ahhhh, glad to see its not just me going crazy! I noticed this issue after pulling away from ATT with my new iphone 6. Was glad to get on this new device with what apple says, Improved LTE. Which I instantly new would translate into, more trouble with LTE. As soon as my phone jumped off wifi as leaving the store in a Strong LTE service area, my phone said 4G. I thought it was just a setting, SO I did all the typical resets and all that, GREAT! LTE came back for 30 seconds, then back to 4G.  While I do get LTE at times it seems to drop it often. My wifes iPhone 5 is holding LTE fine, AND the ping times are half of what mine are. I have not been to ATT yet but hope to soon. I will see if this fixes the problem. Every time I run out and get a new iPhone model there is some major problem I get stuck with. 

    P.S. two more iphone 6 from friends and family are having the same problem. Except one of them will not hold LTE signal at all, sitting next to the ipad mini holding LTE strong.

    Yes, today I had 3G in a new city I was traveling. Did not move from where I sat. It said 3G, slow service, could not get GasBuddy to work, kept spinning, and then switched airport on and then off, BOOM LTE..my app's where not working.  Later that day, the same.

     

    Also it is constantly going back and forth.

     

    NOT HAPPY,

    This is probably not a carrier issue.  It's an Apple issue.  Since Apple does not let its customers (nor it's lower level tech support people) know of known bugs in its software or hardware, it's up to users to get frustrated of find out for themselves.  There are a multitude of problems with iOS 8, and 8.0.2. Particularly with the iPhone 6.  The LTE/4G issue is but one of them.  I have sent this report to Apple's bug reporting site (as should you all), but don't expect a reply.  I can restart the phone and LTE comes back.  I can reset network settings and LTE comes back.  I can restore as a new iPhone and LTE comes back (but other problems arise).  But sooner or later, LTE goes away and 4G comes back. With it, the iPhone 6 begins to heat up as it tries to fine the LTE connection.  And of course battery life drops dramatically as well.  I have called Apple tech support and now they can actually pull up diagnostics on the iPhone.  For mine, the battery and hardware tested fine, but there was errors appearing in the software and operating system.  While these errors were not specific, it does indicate buggy operating system.  With the fiasco of iOS 8.0.1 which made it all of about an hour before being pulled for killing cellular service altogether, it makes sense that in the rush to get something out, errors were still made with the LTE/4G side of things.  I hope that Apple can get it right with 8.1 and that it comes out fairly soon.

    So, Apple doesn't let its customers know about 'known bugs', but then you acknowledge that you know that Apple pulled the iOS 8.0.1 update very quickly, which proves they take action regarding 'known bugs'.

     

    Interesting contradiction.

    After two days on the phone with Verizon (Vzw) tier 2 support and Apple
    support I was able to get an answer, and get this fixed. There are some known
    issues with the Vzw iPhones staying in extended mode - so check these first!
    This is a very important issue to get fixed because until you do you are stuck
    on other cell operators towers and not Vzw and you will not get high definition
    calling!

     

     

     

     

     

    1) IMPORTANT- If you are using a Vzw Network
    Extender
    in your home or office, since update of iOS 8.1 you
    will always see extended mode on your phone, no matter what, for now. (4g HD
    calling not yet available through Vpn tunnel)

     

     

     

     

     

    2) 8.1 apple update defaulted all the iPhone cellular mode LTE setting to data
    only
    .  to fix, go to settings> Cellular > Enable
    LTE > Select
    Voice & Data. a check mark
    should appear within 30 seconds and Verizon will reappear on iPhone. If the
    check mark appears you are now back on Vzw cell network and have High Def
    calling. If not - complete a "hard reset on the iPhone" Do this
    by holding down your power button and home button until you see the apple logo
    on the screen, This actually disconnects the batter on the phone and forces the
    sim card to reach out to the towers and reinitialize settings.

     

     

    If this does not work, toggle on and off Airplane Mode

     

     

    If that does not work; go to settings> General> Reset> Reset
    Network Settings

     

     

    Now if after all that your check mark does not appear or you get a pop box
    on the phone that says "call Vzw to enable LTE calls" then here is
    the solution:

     

     

    Call Vzw, have them add the following 3 codes on your account:

     

     

    A) Advanced Calling 1.0 - Vzw Feature Code 81143

     

     

    B) High Def Voice - Vzw Feature Code 81158

     

     

    C) High Def Access - Vzw Feature Code 81186

     

     

    If you give the Vzw rep the three feature codes it will make your life
    easier because this is a very new issue!

     

     

    Now you can hard reset and select LTE Voice and Data and get back on the Vzw
    Network

     

     

     

     

     

    2 days and 4 hours on the phone with both companies solved this issue, I am
    not that smart, just pushy to get my new HD calling that I bought the dam
    iPhone 6 for! Cheers!  gene

     

     

     

     

     

     

     

     

    Note: When doing all this you must be in good range of a Vzw cell tower and
    have at least two bars of signal on your phone, if not go outside.

    Something like that. I got my lte compatible SIM card. But lte is not working. And I can only switch 4G on/off there no any 3G on/off. And I can use 3G to access interne. You know how to fix this issue. And I contaced carrier and the told me that my sim is working with 4G.

    I got a new iPhone 6 Plus in December and had problems with LTE from the beginning. Could only use the internet via WIFI most of the time. After getting a new SIM card, I still had the same problem. Calls to Verizon and Apple help desk did no good. I made an appointment at my local Genius Bar and while they could not diagnose the problem either, they put me in touch with tier 2 help at Verizon. After almost a month of daily frustration, we figured out the problem was that my Verizon data Usage Controls were set too low. It must have been on a default setting to limit my data usage to 1 GB and then stop all data usage once the 1 GB data limit was reached. I did not even know this control existed. In case it happens to someone else who is as clueless as I was, check your Verizon Usage Controls by clicking on the "Usage Limits" tab.
