I need assistance with LTE Radio - ONE Q&A, Help & Troubleshooting

Hi, I have a 64gb OPO in USA on Straight Talk, using AT&T network. For some reason I'm not able to get an LTE signal in Burlington, Vermont area despite LTE service being available locally. As soon as I cross into New York, New Jersey, or other states I can and do receive LTE signal, so I know my device and Sim card are capable. Others have told me AT&T uses an unconventional LTE band in this area because they took over another carrier called Unicel. What I need help determining is what band they use locally and subsequently which radio I need to flash to get LTE on that band. Currently my battery drains fast constantly switching from hspa to hspa+, yet doesn't do so in other cities and states. Any help, and links are greatly appreciated.

The OPO hardware LTE bands are: 1, 3, 4, 7, 17, 38 and 40. ATT US uses bands: 2, 4, 5, 17. So, if your ATT LTE signal is on 2 or 5 you won't get LTE in that area on your OPO. The bands are a hardware limitation of the OPO and can't be unlocked, as some people have tried in this thread: http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455.

[Q] Verizon Razr Maxx HD LTE in Canada?

Hi Guys,
So I got a new Razr HD from Verizon, and took it to Canada where I live. I travel a lot from the USA to Canada. The phone specs seem to indicate that it has all the bands necessary to support all the GSM and LTE bands as well as CDMA when in the states. I was able to easily get 3G/H+ service from Rogers in Canada by simply changing the Network Mode to GSM/UMTS instead of Global and then adding an APN for Rogers. However, I cannot get LTE service. The LTE choice seems to be bundled with CDMA LTE/CDMA but I don't think that matters, I think its just a radio choice. However, when selecting this, I get an error from the phone saying "No LTE networks could be found" and Do I want to switch to GSM?
This is sad because the phone would be excellent on LTE. Does anyone know how to get a Verizon branded phone to run on Rogers LTE?
If you have any ideas let me know, I will test them.
Thanks,
Blue

Short answer, you can't. Different LTE bands. Rogers is 4 and 17, Verizon is 1, 3, 5, 13, 25. No overlap, and no-one currently makes LTE hardware that supports ALL LTE bands.

Just wanted to add to this... I tested my Samsung Galaxy S3, a generic version that I got from Amazon, works on AT&T in the USA on LTE and in ROGERS in Canada. Too bad the Verizon Droid does not support a similar global LTE band. Or does AT&T and Rogers simply have the same LTE bands???

Yes, AT&T and Rogers have maintained the same bands since they were partnered maybe 10 years ago. Fido is owned by Rogers, so it also uses the same, from GSM up to LTE.
Neither AT&T or Verizon use "global" LTE bands, because there aren't any. Almost every country/provider uses different bands. There's some crossover, but with LTE, buy a phone for the market you are in, because you probably couldn't afford the roaming rates abroad anyway.
Hey guys, I think I have a related question.. maybe you guys can help
I live in Toronto and Rogers is my wireless carrier. From my understanding, Rogers operates on band 4 (1700 / 2100 mhz) as well as 2600 Mhz.
I am thinking of gettnig the new DROID MAXX from Verizon. I have tried asking the Verizon / Motorola reps about whether the LTE would work in Canada but wasn't able to get a firm answer.
From the Motorola website, however, as well as from gsmarena.com, it looks like the DROID MAXX will have access to not only LTE 700mhz, but also at 1700 and 2100 mhz.
What are the chances that this phone will work on Rogers LTE?
Really hoping it could work out... let me know if you guys have any ideas..

AT&T LTE Phones on T-Mobile's LTE network

So T-Mobile seems to be ramping up their LTE coverage and my area seems to be one of the LTE markets.
I was wondering, would now be a good time to buy an AT&T Android LTE phone (like the Note 2 or GS3)?
I'm not entirely clear if the LTE on those AT&T phones will work with the current/future T-Mobile LTE network.
Right now I'm currently using an iPhone 4 on T-Mobile. I get spotty 3G coverage since I'm in one of the 1900MHz refarmed areas. Would using an AWS LTE compatible AT&T phone let me get T-Mobile LTE service?
Is T-Mobile eventually going to get rid of their 3G service on the 1700MHz frequency so they can use it for LTE and then put their 3G service on the 1900MHz frequency?
I can't afford a brand new phone, but when it comes to used phones it always seems that AT&T ones are cheaper to buy than T-Mobile equivalent.

It has been my understanding that AT&T and T-Mobile smartphones are network cross-compatible because they use the same bands for HSPDA and LTE. So as long as you have the following, you should be good to go.
First and most important: ***Phone Unlocked***
The correct sim for the carrier.
The correct APN settings for the carrier. (If this isn't auto-populated after the new sim is in the phone, you can search here on XDA for them.)
Lastly, apply any patches/fixes/tweaks for the particular device where needed. (if needed)
As for this network cross-compatibility changing in the future, odds are that it probably will not happen any time soon as this would be very costly for the carrier to change so soon after launching the LTE service. Post-LTE, maybe, but that is at least another 10 years away if I had to guess. :fingers-crossed:

[Q] 1800MHz LTE Band

This phone is the first phone Verizon is selling (except the iPhones) that has the 1800MHz LTE Band (band 3).
When I saw this I was particularly excited as I visit Australia often and that's the band Telstra uses. I am currently in Australia now, and I am unable to pick up any LTE on this phone. I have gone through every possible mode in the phoneinfo app, but none will get any LTE signal.
I am using a Telstra SIM that has LTE service and I put in the correct APN settings.
The only possible explanation that comes to mind is that Verizon is blocking the 1800MHz LTE band from being used, just like the S4 came with AWS but only a software update pushed later on was able to unlock that band. If that were the case, is there any way around it?
Any other ideas why it's not working?
I tested my SIM in the same location in a iPhone and it got lte

Bit of a necro-post, but I asked both HTC and Verizon associates and they said that it should work...so don't know if some bad information has been passed my way or GSM/LTE is just being funky (I do remember reading that has been, or was, a problem)

LTE and Verizon

Has anyone with a Verizon data sim try and drop it into the LTE model yet?
Curious if it picks up a data signal.

When I scanned for networks while playing around, I noticed that it did find the Verizon (4G) network. Obviously, I have no idea if it works as I'm on T-Mobile, but I thought I'd let you know.

Looking at the specs it "APPEARS" two supported bands are there? The whole thing is annoying honestly, especially when Verizon won't allow an actual activation so you need an active data sim to try.
Confirmed
Verizon sim card does not work. Just got mine today, popped in my Verizon card from my note 2 and it doesn't even recognize the carrier.
A network scan (for my area) only shows at&t and t-mobile.
First the nexus 5 and now this. It's really starting to such to be on Verizon ...
It would only support AWS LTE on Verizon (what they call XLTE). It doesn't support Verizon's primary LTE band, which is Band 13. And AFAIK Verizon hasn't deployed LTE on PCS.
AFAIK there are three makes of the shield tablet

May want to check this out just got it from the shield tablet site - just putting this here so anyone who finds this thread also finds the relevant data
There are three versions of SHIELD tablet LTE. There is a North American version that works on AT&T, T-Mobile and Rogers on LTE bands 2, 4, 5, 7, and 17 and HSPA bands 1, 2, 4, 5.
There is a second International version that works on popular European and Asian networks. It supports LTE bands 3, 7, 20 and HSPA+ bands 1, 2, 5, 8.
Check with your favorite store/carrier to verify coverage in your area and as to what device variant you'll ACTUALLY be getting
That being said Verizon uses these bands AFAIK 13(700 MHz Block C) and 4(1700/2100 MHz AWS) for LTE(XLTE for the latter) and 0 and 1 for 3G (1xRTT/EV-DO/eHRPD) - so the only chance of using it is on band 4 - and that will only happen if the devices radio can use the AWS network which i suppose is possible AND the tower in your area having XLTE support - will just need to see - guess i wont know till i get it since they have XLTE in my town, or it could have a snowballs chance in heck or only work after a soft update..ill post an update on what happens

LTE issues with AT&T?

Hi everyone,
I'm having a couple of issues with my H830 that I'm trying to clear up.
1. Besides having the "Device Unlock" app showing up on your phone, how else can you tell if your phone is actually still carrier locked? I ask because I purchase mine used and it was locked. I did not insert a SIM, ran the unlock app, did a permanent unlock attempt, and it appeared to work. After I completed that, I downgraded, rooted, and updated to the current 20n. I had a few unrelated issues and decided to unroot/lock bootloader/reflash to stock. After I got things back to 100% stock everything, I show the "Device Unlock" app again. However, my SIM is Straight Talk AT&T and its working (mostly, that's the next question). Calls work, messages work, and data (mostly). If I was truely still carrier locked, wouldn't this not happen? Is there a warning I should be getting?
2. I believe I've seen others who have experiences issues when using an H830 with Nougat on AT&T networks, something about Band 17 being broken/disabled. Regarding my current situation from question 1, data is acting weird. If I leave the network mode setting on ""GSM/WCDMA/LTE auto", I seem to get a trickle of data - emails seem to come through, and little bits of websites come through. If I switch to "GSM/WCDMA auto" like I've seen listed in other places, data seems to work as you'd expect other than being on a slower connection. Has anyone else had this problem and resolved it?
sorry, looks like i posted in the wrong board. could a mod maybe move this to "Questions & Answers" board?
As an update, if anyone cares - I've managed to use the phone on multiple different carriers between US, China, and Taiwan. My issue here in the US is due to the network mode - I guess the band AT&T uses around here is not supported by the phone currently.

If you have an H830 that is an Tmobile Specific G5
ATT version is H820
Tmobile uses this channels or Freq bands
Freq Band
1900 MHz 2
1700/2100 MHz 4 AWS
850 MHz 5
700 MHz 12
600 MHz 71
----------------------------------------------------
ATT uses
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 9(1800), 17(700), 18(800), 19(800), 20(800), 28(700), 29(700)
38(2600), 39(1900), 40(2300), 41(2500)
the H830 dont have as many bands as ATT needs , so when there is no ATT LTE bands your phone switches to 2g hence slowwww data speed
If you want full speed on ATT network, get an H820
i do not fully get why you want to use a Tmobile headset on the ATT network
Hope this little explanation helped you

So I to am also using a using an "unlocked" T-mobile Lg G5 with an AT&T StraightTalk Sim from the Bring Your Own Phone Package which has been an absolute nightmare. Love the phone but not the data problems connection problems ...even been ridiculed by an iphone x enthusiast that is in your face annoying about the iphones. I wanna root, fix problems, and show him what a real operating system can do . :highfive:

I'm well aware there are differences in bands; my area apparently doesn't use the same 4g bands as ATT. In many areas, TMobile does, so its not an issue. If you want a G5 that could be unlocked, rooted, and run a custom OS without much trouble, H830 is the way to go. I just wanted to make sure others looking to do the same didn't think they got a bad or locked phone.
Anyone in or around new york using it?? Do you get LTE and 3g?
OP, I don't seem to understand your issue or situation. I will assume you experience poor connectivity with your H830 model on AT&T including intermittent LTE drops, losing LTE after calls, 3G/H+ only, and poor service/coverage. AT&T white-lists devices which can use LTE on their network, and while they may connect, they will get dropped to 3G/2G GPRS after a while. These white-listed devices ONLY include AT&T models of phones, and SOME unlocked phones. This is an issue many OnePlus, Nexus, and Huawei users experience with AT&T. Even though device is unlocked, LTE is gone after a while or never loads. Some have suggested to call AT&T or chat via tech support to whitelist your IMEI on their system, which will take a while to reach the correct person. What I ended up doing was switching to T-Mobile from my MVNO TracFone because they told me AT&T claimed my device was not capable of LTE (These included: G4 H811, G5 RS988, and G5 H830). As for band compatibility, it should not be an issue. AT&T supports bands 2, 4, and 12/17 (29 & 30 are rare), they just added band 12 compatibility 1-2 years ago to gain more customers from T-Mobile but it's working against them because of their LTE whitelist.

Thank you for that data, i did not know this. I will be switching back to a Tmobile MVNO next month. I am with Red Pocket so I can choose either carrier.
I was at a restaurant yesterday and my LTE was SUPER slow and I was wondering why it is slow sometimes and fast other times even with full bars (strong signal)

Sorry for the repeat delayed responses, been away and not getting alerts.
I had a few issues to begin with that were hard to determine due to multiple issues/changes/whatever. Normally I try to do one thing at a time, but I messed that up for myself. Between forum searches are real world testing, I was able to figure them out, so putting them all in one place may be helpful to someone else.
1. I had SIM unlocked my phone prior to downgrading and trying out custom roms. When I wasn't getting LTE, I thought I may have screwed something up and returned everything back to stock. In the process, the "SIM Unlock" app came back and I assumed I may have somehow relocked things. Turns out that's not the case, as I've used an AT&T sim from Straight Talk ever since and others for work in both China and Taiwan. I'd love to get rid of some of the LG/T-mobile bloatware, but I fear breaking anything if I remove this app, so I'll just leave well enough alone.
2. LTE - I was getting no data use at all originally. I couldn't confirm if this was due to a defective phone, being SIM locked, or something else. On my business trips overseas, I was able to get LTE, so it appears to be the band/whitelisting issue as you and others have mentioned. In order to semi-solve my issue, I switched my Network Mode (Settings > Connectivity > More > Mobile Networks) to "GSM/WCDMA auto". I don't get LTE speeds, but 4g works well enough for me as-is. If I ever get around to it, I'll just snag a new Straight Talk sim for t-mobile (although I get shivers any time I even think about having to deal with their customer service department)
