I've spent most of yesterday and today trying to get LTE on Bell Mobility's version of the Nitro. APN configuration, SIM card, account provisioning have all been taken care of yet the phone cannot connect to LTE. Is there something I'm missing? H+ is hooking up fine but LTE is non-existent. I've been in touch with Bell and AT&T's tech support, customer service. mlee1999 (prior owner who was able to get LTE) has also been kind enough to try and help me out with this.
Thoughts anyone?
My only guess is that Bell and Rogers are using AWS 1700 MHz for their LTE networks. AT&T is using 700 MHz and thus is not compatible or 700 MHz is not enabled by default.
LiViD is correct about the frequencies but the Optimus LTE has 700 and 1700 turned on.
There is something else I went through with my Optimus LTE:
When i got my phone, my SIM was an LTE SIM, my Optimus LTE was an LTE handset, and my account was provisioned to a 1GB Data plan, but by some fluke, Bell only allows LTE on the $70+ 6GB plans and no other. I upgraded to the 6GB plan and rebooted my handset and presto! LTE came up.
One other thing is, are you in a LTE area or a fringe zone? might sound like a stupid question, i know.
Oh, and did you call AT&T to add this phone to the account, or just throw in your LTE SIM card?? Most carriers now require you to give them the ESN for LTE handsets to be activated on the LTE network.
Could I request you check my post out please? If you could help we'd be most appreciative!!
All provisioning on my account was confirmed with ATT. I also had them check ATT LTE in my area and they confirmed I should be able to get it.
Love to help you with the other thread but I've never pulled those files. Some brief instructions via PM and I'll give it a try.

APN type: default,mms,supl,hipri
Everything else was left blank or with the default info.
i wonder if this will help?

Seen the first link and it didn't work. Just tried the second link and it caused a FC when trying to connect.
I just got off the phone with AT&T and they can't do anything with an unlocked device. They did look into to it to see if they could assist but since it's not a branded device, they couldn't do much. The tech did say that she could not see APN settings on her side which leads me to believe that without it being set I will not see LTE. As a little bit of background, I'm coming from an iPhone and have switched directly to the Optimus LTE. I had to go thru all the changing/updating and provisioning of my account and even replaced the SIM card all to no avail.
You'll probably have to wait for either a Radio ROM to be released or for someone to unlock the 700 MHz frequency within the factory OS ROM itself.
Not so sure about that since mlee1999 was able to get an LTE connection. Only difference is he was not coming from an iPhone.

cman6453,
You could try flashing the Nitro baseband to your phone and see if that does the trick. Make sure to back yours up first (and make sure mmcblk0p14 is, in fact, your baseband firmware partition).

Was there any evidence provided from mlee1999 saying that he was connected via LTE and not HSPA+? Something sounds questionable about that. If AT&T is using 700 MHz and Bell is using AWS 1700 MHz, that Bell phone would not work on AT&T's LTE network. Sure the device can be unlocked, but that won't unlock the baseband frequencies.
Well, i can assure you now that the 700Mhz band is operational with AT&T via this link:

These settings are confirmed to access the AT&T LTE Network:

I personally doubt that the phone is the problem (aside from the APN settings), I am leaning towards the carrier being the problem on this one (either APN issues or something on their backend).
I will keep hunting to try and help you.
I went out today and added a second line to my account. I even picked up a Nitro (going back tomorrow) to do more "research". As soon as I got home, I switched the Nitro SIM to the Optimus. No LTE. As a matter of fact, no data at all. As soon as I switched the Nitro SIM back into the Nitro all was fine and dandy.
My goal for this exercise was to be able to switch, EASILY, between an iPhone 4S and an LTE device. Well, doesn't look like that's going to happen. Even if I got the LTE to work switching back and forth would be too much work given how randomly I switch between devices.
So I've pretty much exhausted this experiment. Thanks to all that put in there 2 cents!!
Rep - I also think it's something on their backend that's preventing LTE from lighting up. I originally thought, put the microsim in an adapter, pop it into the LTE capable device and off I go...BUT noooooooo, 3 days of pecking and hunting and big brother beats me...DAMMIT! I'll live to fight another day!!
When I first tried LTE phone I also didn't have internet at all (though as phone it worked fine), I had to call ATT to activate my sim card on their end.
Quick summary of the steps I went thru to try and get the Optimus to connect to AT&T LTE.
1. Confirmed I was in an LTE area.
2. Changed my AT&T plan to an LTE data plan.
3. Confirmed APN settings on it were the same as that found on the Nitro.
4. Changed my SIM to a "70357" SIM. That's the SKU for the SIM that they're using on their LTE devices. I checked the Nitro that I purchased and VOILA, same type SIM.
5. Confirmed my new AT&T plan was associated to the IMEI for the Optimus.
When I swapped the SIM from the Nitro, I thought I was finally going to be in LTE heaven. Nope. Not a chance but I do have a good idea on what the problem is/was.
The Nitro's IMEI was associated with that specific SIM. I went thru this process when I initially changed my plan to accomodate the Optimus. The CSR asked for the IMEI AND the UICC from the SIM. Apparently AT&T's system doesn't recognize the Optimus' IMEI. The CSR mentioned that but was able to leave the IMEI as-is. I confirmed the IMEI was not recognized by going into an AT&T store and a CSR there noticed that my account was using a "regular" GSM phone when I asked about no LTE on the Optimus.
SO.....what I'm thinking was that since the Nitro's SIM was associated with the Nitro, when I placed it into the Optimus AT&T's system noticed the UICC of the SIM was not associated to the appropriate IMEI so it was denied access to LTE. Vice-versa with my original SIM when I placed that into the Nitro. As soon as I returned the SIM's to their usual devices, LTE returned for the Nitro. WHEW!!
Moral of the story: iPhone and LTE devices, at the moment, take a lot of work to swap out regularly. So, for now, I'll be sticking with H+ devices and going along my merry way.
In case anyone was still curious, here is the definitive answer on the Optimus LTE's AT&T LTE connectivity! I am on vacation back home visiting family in Illinois, and decided to bring my Optimus LTE along for the trip, to see if I got LTE in Chicago. The line is provisioned with LTE data, and has an LTE compatible SIM.
This makes me happy, because that means now I can import other devices with the 700Mhz or 1700Mhz LTE bands and be able to use them on AT&T's network!
So i have a Rogers i747M unlocked and im using it on AT&T. I know the LTE bands are the same but I can't get the LTE to work on it. Is it even possible ? I can't change the "APN Type" on the i747M like the AT&T version can. Do i need a real AT&T micro sim ? Do i need to flash the modem (already know that it might kill the imei if i flash a AT&T modem onto it) ? Do i need a real Smartphone data plan ?
If anyone has got the i747M LTE working on AT&T please post your setup, apn settings, sim card, and any other things you did to get LTE working.
Thanks!

All you should have to do is ADD the AT&T APN and YES you'll need the LTE plan, no more flying under the radar with $10 per month data

i cant add the exact apn settings, the "apn type" field is only a 3 button choice on the i747M, whereas the i747 (AT&T version) has a text box the for "APN Type" that you can type anything in.
ive also tried another AT&T micro sim from another active i747 in my canadian S3, and still no LTE ....
i didnt dare try my cut dumbphone sim in that S3 though lol....
update SIM

Hi! I had a similar problem, I kept getting HSPA+ only and then I realised my SIM wasn't LTE "ready". I went to a Virgin mobile store (or ATT in your case) and asked for an LTE capable SIM. 5$ later I had 22mbps download and 13mbps Upload speeds
I have a T-Mobile GN2, and have both TMO and AT&T sim cards. Right now when I plug in the AT&T sim card, I get 4G signals.
Since both devices are identical (based on a 3rd party site), can we install the AT&T rom in an unlocked and rooted TMO GN2, and thereby enabling the LTE functionality??
Or will such attempt brick the phone??
What data plan do you have with your ATT sim? You need a LTE sim and an LTE enable data plan with the APN on the phone before even testing to see if LTE works out of the box. Im wondering the same about the status of the LTE radio on the TMO Note 2. Let me know if you find out anything new.
HI, This phone that I bought from italy is supposed to me unlocked. I can call but cant get data to work. I know 4g will not work here in the usa but how can I get 3g to work? Also using an att sim card
What phone version do you have,
Verify the correct APN in settings.
I bought a 710VM unlocked. It updated all the way through to G710VM20c with no problems. I have put in a T-Mobile Sim, an AT&T sim and both were live instantly on their respective networks. I am a Verizon customer though and when I put in my Verizon sim it defaults to US Cellular. All my data is roaming. I can make phone calls, get texts and MMS just fine but it is all while roaming on US Cellular. I have updated the APN to the proper Verizon version but it still doesn't log onto Verizon.
Any ideas on how to fix this? Seems strange that only Verizon is putting up a fight. See attached photos.
Thanks all!
Take vzw sim out factory reset shut down phone. Put in vzw sim and reboot.
