    Anyone else having problems with getting the One to work on AT&T's network using LTE? I can get HSPA+ on it, but just won't do that 4G/LTE.

    I suspect its a problem with AT&T's network not recognizing the IMEI class for The One as indicated here, but I was curious if others had got around this problem.

    most likely an issue with APN's. You can try searching on google for a AT&T LTE APN setting and edit it.
    To edit your APNs, go to Settings>Mobile Data> APNs

    agreed. This is similar to when I had apn issues. All it took was reentering the apn #'s.

    Moved to technical support

    Did you give att your imei number? That could be a reason

    Another user had some trouble with this but it was because he gave att the OnePlus One's IMEI
    He got it solved by having att change the IMEI to one from an HTC One m8

    Also check apn as others have said

    There are several options for ATT APN but I haven't modified any of them. But with that said, I've tried all of the AT&T APN options and the highest I can get is HSPA+. Here are the LTE APN settings that don't work:

    Name: ATT LTE
    APN: pta
    MMSC: http://mmsc.mobile.att.net
    MMS Proxy: proxy.mobile.att.net
    MMS Port: 80
    MCC: 310
    MNC: 410
    Auth: Not set
    APN Type: default,supl,mms

    If you don't mind sharing your APN settings, it would be appreciated to compare.

    I did in fact give them the IMEI number. I suspect this is what the issue is...problem is I don't have access to an AT&T Android phone so I can't give them an IMEI.

    just go to the att store and find the needles salesperson or ask for someone experienced with byo off contract phones. they're promoting byo phones but not training employees how to deal with non att phones. my apt was correct but the had the imei problem mentioned above. I'm guessing oneplus will get att the info necessary to recognize the native imei, but in the meantime they will have to enter another phones imei that's already provisioned with lte into the system. in my case the salesman entered the imei from his own phone, an LG flex into my account. this fixed my connectivity problems and my visual voicemail problem. everything is great now.

    I had a friend of mine let me use his IMEI number from a broken Galaxy Note 2 and I chose AT&T phone when inserted the sim. I used the AT&T online chat to get everything setup and all is well with me. I am going from iPhone 5 to OPO.

    I went to the ATT store yesterday to do the BYOP plan and gave them my girlfriends Nexus 5 IMEI. Got LTE right away!

    LTE no problem here. But I stopped telling AT&T my imei a long time ago. they still think I have my s4 from last year.

    Yeah i'm having the same issue switching from an iphone 5. Stuck on H+ which crawls. I honestly don't know much about the technical aspects of phones.. Will somebody send me an imei I could use? Or are they supposed to be protected? I would love to call customer service and be able to switch to LTE

    Worst case - go out and buy a backup phone that can do LTE - I would suggest a cheap ATRIX HD - you can load cyanogenmod and get latest android plus its unlockable and rootable. and it does LTE. if you look on craigslist or ebay you should be able to find one for 100-140$ Has a microsd slot too. and is great as a backup phone.

    Update - It was in fact the IMEI. Basically if AT&T's system doesn't recognize the device IMEI then it just makes the conclusion that its a feature phone and only capable of 3G/HSPA+. Once I created my own IMEI and gave it to them, I rebooted and boom...4G LTE.

    does it display "LTE" or just display "4g". i thought the consensus was that cyanogen displays "4g" even though it's actually LTE.

    When I check the Settings | About Phone | Status it is reporting LTE.

    Screenshot_2014-07-12-17-45-25~2.jpg I found a way you can just make it SAY LTE instead of the 4g logo. Root your phone, install xposed frame work (if you dont know what it is dont ask just stop right here). then load the module GRAVITY BOX for KK and theres a setting in there that lets you change display for 4G logo to say LTE instead.

    I stopped by a store the other day, rep put in his IMEI number and I had 4G after a restart. He said LTE should actually show once the phone does a "network reset." He said, normally you can trigger one by removing the phone's battery, but that's not really an option here. He said it will eventually do a network reset on it's own, but didn't know when. Getting very fast speeds now.

    Played w/ APN settings forever and nothing happened until rep put his IMEI in. Get someone to do that.
