Hi,
I have an unlocked version of Fire Phone and have flashed the almost latest version of the Cyanogenmod ROM. I am using at&t wireless service but it seems that I just cannot use LTE. Based on other information I think the phone supports all the bands at&t is using. The network the phone is using is HSPA. I tried changing settings in the phone but it did not help. I searched carefully using related keywords but have not found anybody talking about this, and I wonder whether this is something too simple to ask or nobody else has ever encountered this problem. I want to know if there is something I can do to use LTE.
Thanks.

I have seen some issues about CM based ROM's and ATT LTE. Did you have a full LTE signal and good data speeds on the stock ROM before you flashed the CyanogenMod ROM?

Thank you for your reply. Unfortunately, I had already flashed CM before I switched to att so I do not have information about that. And currently I am not quite willing to flash the phone back to the native fireOS just for this because HSPA still gives good data speed...

Have you checked your APN settings and verified that it is setup correctly to use ATT LTE? Also, was this phone ever used on ATT before with the sim card you put in it? If not, then what will have to happen is this, I think: I found this excerpt which I believe is what will have to happen.
You WILL NOT get AT&T LTE on you phone unless your account is first provisioned with an AT&T LTE Phone. There is NO WAY around this. You must buy/borrow an AT&T phone that has LTE capability, put your SIM in that phone, and let the system provision your account for LTE automatically. This is NOT something that customer service, or a store clerk, can do for you. Once your account is provisioned for LTE (you will know because the LTE indicator will show up on the phone), you can then put the SIM card into your Fire Phone. At that point, the device will automatically select the "phone" APN, and you will get LTE (identified by the "4G" indicator).
Hope this helps

I've been searching both the T-Mobile and AT&T S III forums but haven't found my specific question.
I have an unlocked AT&T S III that I'd like to move over to T-Mobile. While I was in their store today I was told that I couldn't access their new LTE network in my area until Samsung sent out an OTA update. I know all LTE networks aren't created equally but I'm accessing AT&T's just fine, averaging about 32Mbps down and 10Mbps up.
I can't find any information about a Samsung update that would let me access T-Mobile's LTE network. I did a few speed tests with their SIM card in the store and the best result was 3Mbps down and 1Mbps up.
Any thoughts on this supposed OTA update or what I'd need to do to access their LTE using my unlocked AT&T S III?
For what it's worth, I'm currently running CM 10.1 M2.
Well according to this http://en.wikipedia.org/wiki/List_of_LTE_networks
Both At&t and Tmobile use 1700/2100 AWS. So once Tmobile releases the new Galaxy S3 someone can extract the radio from it's firmware. You could then flash the radio on your device. Alternatively you could simply enter the APN settings from Tmobile's Galaxy Note II which already (due to recent firmware update) supports Tmobile's lte network.
You can use this site to check on the progress of Tmobile's lte deployment.http://sensorly.com/map/4G/US/USA/T-Mobile/lte_310260

The APN change is a solution I haven't heard about. I'll probably head back to the store tomorrow to test this theory. I'll give feedback regardless of how it goes.
Please do I had the exact same question and I would appreciate it. Thank you.

I wasn't able to test this theory today because I couldn't find reliable T-Mobile LTE settings. I also read that changing or adding new APN settings can have adverse effects like Google Now not working. This makes me a little hesitant to try it even if I can find the right config.

Ah ok, you should be able to delete apn settings you add after testing. I don't have the phone in my possession or else I would test it myself. The settings I believe are changing the apn to fast.t-mobile.com while keeping everything else the same.

I currently have ATT service with my S3. I'm running the Intergalactic 3.0 at the moment and I absolutely love it. However - I just switched to T-Mobile. I want to keep my current phone and sell the free S3 they gave me so I don't have to deal with losing any information or anything like that. Can I get away with this on the ATT based ROM? IIRC T-Mobile and ATT run on very similar networks/frequencies. Any advice would be helpful here. If worst comes to worst and I have to use the T-Mobile provided phone, can I flash Intergalactic on it as well or do I have to choose from the T-Mobile ROMs on this site?
Thanks to everyone in advance.
You should be able to add the proper apn for t mobile. You also may want to flash one of the t mobile radios.

Strange. I unlocked the phone, I was able to put in the SIM card and the APNs filled themselves. I was able to make calls and texts but unable to use internet. Any idea here? Using Intergalactic 3.0

Strange. I went back and re-registered on the network through the settings and now it's getting 4g, just no LTE. At least it's working though!
Edit: Kinda. It worked for a minute then I locked/unlocked the phone and it didn't want to work any more.

I have been searching and cant seem to find anything... :/
I am trying to SIM Unlock my LG G Pad 8.3 Model VK810 that is Verizon and should come factory unlock I believe. I need this to be used on AT&T LTE which I have a sim card for and a tablet plan on the shared data plan.
It is on 4.2.2 baseband is m9615a-cefwtazm
I tried adding some ATT APN settings I found, but that did not help me. I think I need to Change it to GSM From CDMA somehow? I am not really sure. I can update and root if needed or whatever I need to do. I also have a samsung z3x box, but dont think it will work on the LG.
Any help would really help me out! Thank you in advance.

As it seems you are comfortable messing with your APN settings that should be all you will need to do. The device is locked to specific wireless frequencies but luckily for you at &t uses the same LTE frequencies. You will need to have root access in order to write your APN settings though, check the forums for information on that. Finally make sure that the sim you have is compatible with your tablet data plan, and your APN settings should be as follows for mobile data only.
APN: BROADBAND
MCC: 310
MNC: 410

I do not, I am sure you will find something if you look around. The V500 and V510 methods are not compatible. There is a method for yours though along with a custom recovery in the works. You may even have a custom rom in the near future.

So, I should Root this and then change the APN settings to what you told me and my ATT SIM would work?

I haven't read much about i0root but it looks like it will work. Now the next part is not certain weather or not it will work, but I have seen tablets able to run on other networks that are unlocked. As long as Verizon did not implement any extra protection you should be able to use an at&t sim that is enabled for tablet data.
Once you are rooted go pick up es file explorer and navigate to /system/etc/apns-conf.xml . Make sure that before you change anything that you make a copy and name it something else so you can find it again if you have to go back. Open the file using the text editor. You can get rid of the other apns and just put your new one in there and give it a reboot. It should kick right on after you reboot. Good luck!

I have installed a T-Mobile SIM card in my LG GPad 8.3 LTE so I could get the free gig of data they offer existing customers. It worked without rooting. All I did was add a new APN with the proper T-Mobile settings and I was able to surf. Did it right there at the T-Mobile store with the rep to verify it would work before I added the data line to my account.

Thx for the tip. The tablet is set to LTE mode and since T-Mobile LTE has the same band with Verizon LTE. It definitely works on T-Mobile.
For AT&T, no luck even if rooted. I used Radio Switcher app to go to the Tablet Info in Testing Mode. But it displays error message "This application does not work on this device".

Vk810 supports lte bands 4(aws) and 13 (700mhz block c), bands that Verizon uses
T-Mobile uses band 4 for lte mainly, will use band 2 (1900) and 12 (700 MHz block a) in the future as well. Vk810 will work on T-Mobile wherever tmobile has LTE right now (with band 4)
Att uses band 4, 2 (1900), 17(700mhz block b) and 30(2300mhz). Vk810 will only work on att if at uses band 4. If att only used band 2 in your area, your att phone (which supports band 2) will show LTE, but vk810 won't work
I don't know if there is a map showing which bands att uses in your area. There is a spectrum map showing who owns which band in which region, but no guarantee that att has active cell sites

I seen the sticky saying not to flashing any rom from another carrier but I've flashed dozens of different roms and all has been good except the roaming.

You might have to configure your APNs, or, if you haven't for a long time, you might need to update your modem, since you don't get that sort of update with custom ROMs. On my Virgin Mobile phone, I have to flash an APN fix on every new ROM, otherwise I just have 3G.

The straight talk version I have runs off Verizon towers and they have 4G disabled but the phone is suppose to be 4G enabled. The apn fixes didn't help. I'm wondering if this would need something like cdma workshop.
Ah, I see. Yeah, if the 4g is blocked on multiple ROMs, you'll need an app to fiddle with the sim card. Hopefully it's not hard blocked (a physical switch or the card is incapable of it even though the phone is)! I'd try to contact Straight Talk and/or see if it works on stock. If you're trying to get 4g without straight talk knowing, well, I don't know much about that, but CDMA workshop or something similar might be worth a shot.
I was thinking cdma workshop would be the answer but I don't know where they have it turned off. It sucks being confined to 3G when the phone is 4G compatible and straight talk will allow 4G on there Verizon network now.
So I jumped on the AT&T/DirecTV Unlimited data deal and ported my phone today. It all looked normal and I got the activation texts and such - it even populated the nxtgenphone APN info (though it was deselected and I had to select it). Anyway, I've had no data at all. As a test, I switched the APN to phone and data works, but the speeds appear to be much lower than what my wife's iPhone is seeing on the nxtgenphone APN. Anyone got any tips?
I'm running Viper 2.5, latest US unlocked firmware and US unlocked selected as carrier, and it works fine on AT&T other than this......only other thing I can mention is when I select preferred band or whatever it shows WCDMA/GSM and if I change it to WCDMA/GSM/LTE it reverts back for some reason. Any help much appreciated. I've called AT&T and they're like, uh, we don't sell the HTC 10 so can't really help you... grrrrrr.....

I'd suggest ruu to stock us unlocked rom and see if the issue persists.
Or, try clean flash of viper.
I have no issues using US unlocked on AT&T with both stock rom and ice.
Thanks for trying to help. I just finished trying stock RUU and same problem. I'm convinced, as I was before, that this is AT&T's issue. I've read numerous posts this afternoon that because the HTC 10 (and other phones) aren't in their "LTE approved" database, nxtgenphone APN won't work, or it will only give HSPA speeds. Seems like everyone who has resolved it, or didn't run into the issue at all had another AT&T LTE phone they could use for the IMEI on the account, or the rep entered the model as an iPhone or similar to make it work. Really, really frustrating, as they refuse to help me and I'm starting to think I should just terminate in the 14 day window and do T-mobile or Verizon.
I have at&t and everything worked out of the box, I've never been on stock rom, always on Viper I did the unlock and s-off without a sim and never had an issue or called at&t to activate the device I just transferred my sim from my note 4 to the HTC 10, no provisioning issues at all, VOLTE works, LTE is fine as well while on a phone call... No issues... If you need anything to compare let me know

Thanks for replying. They did confirm it was a provisioning issue and they fixed it today. They had to do something different, as the default HTC 10 provisioning and IMEI check didn't fix it even when they tried it a second time, but they were able to adjust something and LTE definitely works now. VoLTE working here, too. Thanks!
