APN settings for my OnePlus One

Just got a OnePlus and it is defintiely LTE compatible based on the device specs (says it is bands 4/17 compatible). 

 

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?

Hi:

 

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.

Hi:



Just out or curiosity, is your One Plus One phone "US Spec"? For example,
does your back cover say "CYANOGEN"?

Mine says CYANOGEN on the back.

Hi Matt:



That explains it. With saying "Cyanogen" in the back means this phone is
for export (or for the US). So it has the right bandwidth/frequency to
utilize AT&T LTE. I bought one that is for the Chinese market, and it never
worked for the AT&T LTE. So, I bought another one just like yours, and once
I gave AT&T the IMEI number, it picks up LTE right away.



Thank you very much for the clarification. Chinese domestic model, do not
have the right frequency for AT&T LTE. Have a great day!



Sincerely,

Joseph

Hi, I just got my OnePlus One 2 days ago and followed your instructions to get some sort of mobile data to work. However, it's H+ and not 4g LTE. What do you think I could possibly do, to resolve this issue?

Thanks in advance

Hi??



First of all, is your One Plus One, Global version? If you purchased it
from China, then it does not have the proper band for AT&T LTE.



It??s quite simple to determine which version that you have, just look at
the back cover. If there is ??Cyanogen?? sign at the bottom of the back
cover, then you have the global version, then you can use AT&T LTE. If
there is no such ??Cyanogen??, then you have the Chinese version, then you
can??t use AT&T LTE.



The reason I am certain about this is because I own two One Plus. I first
purchased one in China, and no matter what I do, the most is H+ (even after
I gave AT&T my IMEI number). Then I received an invite, so I bought another
One. Then I just called AT&T and give them the new IMEI number again, and
it works immediately. So I am certain it has to do with the version of
hardware that you have, I also verified this with One Plus representative.
They confirmed that Global version, has different frequency coverage from
their China domestic model.



If your unit has ??Cyonagen?? on the back cover, then you need to:

1. Make sure you have LTE package for your service

2. Have the new SIM card

3. Call AT&T and give them your IMEI number



It should work immediately after AT&T has the IMEI number.



I hope this helps you.

OnePlus One do not support 850MHz for LTE band 5 as AT&T use in some areas. That why whatever you do you will not get LTE data with this phone in some areas. I'm surprise that support team from AT&T do not know this.

I am currently on a oneplus one phone I get 4g LTE, I removed the Sim card from my Samsung Galaxy s4 inserted it into the slot of my oneplus one phone, I have high downloading speeds and enjoy all the comforts of a 64 gb phone with 3 gb processor speeds. AT&T sees the unknown phone and had never inquired. Customer service is able to troubleshoot on your phone anyway. I am still a customer of AT&T. Hope this helps

Hi all,

  Posted a new thread about this but saw the comments from the AT&T employee and thought I'd share what customer service supervisor said today.

 

He had apparently worked with the IMEI team on a project in which they were working out how to support phones that were not originated with AT&T (or any carrier).  The current "fix" was to send an email to the "IMEI Ranges" team with the IMEI #(s) that needed to be added.  She cautioned that it could take 2 weeks and that I would get an e-mail confirming once completed.

 

FWIW...
