Now, when I spoke w/ ATT on the phone they said the device may not work at LTE speeds. From what I'm reading online, this is because the SIM I'm using has never been registered on a LTE network.
Users of other unlocked phones have mentioned this is an issue and have suggested the following:
Put the micro SIM in a compatible LTE phone and turn it on. The SIM should register on the network. Put the SIM back in the unlocked phone and you should be good to go.
To test that I'll have to find a compatible phone, but so far changing the APN settings hasn't worked.
Any thoughts from ATT or otherwise?

Based off the specs of your device, you should be in the clear for LTE data service to work on your device as long as you have LTE service in your area. There are two things that you need to check on. First make sure your APN settings are set to the latest, most up-to-date APN settings. You can find the most recent APN settings by clicking Here
Second, you need to make sure that your data plan is reflecting an LTE enabled device. I have not personally delt with the OnePlus One device, but tech support should be able to get your plan set up for LTE data if it isn't already set up. You can check if you have an LTE data plan by logging into myAT&T.
Hope this helps!

Appreciate the response! I am sure LTE is available in my area.
When I have the APN you linked to selected my device says "No Internet Connection." I can make calls and text, must no data.
If I switch the APN "ATT Phone" with these settings:
Proxy/Port/Username/Password/Server: Not set
MMS Proxy: proxy.mobile.att.net
MMS port: 80
Authentication type: Not set
APN type: default,supl,mms
APN Protocol: IPv4
APN roaming protocol: IPv4
Then I get data (looks like HSPA to HSPA+ speeds).
To the second part of your response, when I called in they said that because the phone is unlocked and the IMEI doesn't show on their system, therefore they can't guarantee LTE Speeds. The system actually said it was putting me on a 2G plan.

I apologize you're still having issues with your device. I personally had this problem before a long time ago with an old blackberry. The issue is your account thinks that you have a 3G/HSPA+ device as our default data plan.
You can reach our to our Tech Support line (1-800-801-1101). They need to manually change your data plan to an LTE data plan. A store won't be able to though their system will only populate a data plan off the IMEI of your device. You can say you have an unlocked pure Android device (Nexus 5, or a Google Play Edition of a device) and they should be able to get you squared away.
You can also send a PM to ATTCustomerCare and they can assist as well. You can expect a response from them within 2 business days. You can send them a PM by clicking here.
Hope this helps!

Can't speak for others, but the settings you provided above for AT&T Phone APN did the trick for my OPO. Got connected HSPA at first, but after a minute or so the 4G sign showed up. I use GoPhone SIM and was previously using an international (non-LTE) Samsung S3. I first tried to get help in the local store, but they had no clue.
Only trick for me was remembering to save the APN settings through the top right button - if you simply go back it loses changes.

I should add - they did add my IMEI number to my account in the store.

Hi, curious what type of plan you're on?
My OPO is in the mail on its way to me. I'm using a feature phone plan now at $50/mo all unlmited.

I also got a One Plus One from China, then I flashed it with CM11S. All I can get so far is H or H+, just couldn't get 4G.
I have the latest APN, 4G LTE plan, asked AT&T tech support to update the IMEI number. Still no luck!
I am curios to find out what did your local store do to make it workable with 4G/LTE.
Appreciate it a great deal if you can share the ultimate trick to make One Plus One 4G/LTE compatible.

What I did was go into the APN and instead of choosing AT & T LTE, I chose ATT Phone instead and then LTE lit up after about a minute.
The order under APNs for me are: ATT (wap.cingular), ATT Activation (Iwaactivate), ATT Broadband (broadband), ATT LTE (pta), ATT Phone (phone)......
Hope that helps.
