I'm having a hard time finding a definitive answer about which LTE band I'll lose using the tmobile variant on att.
I don't think any, I think both are identical. I am using the N920T with AT&t. I would suggest you consider using DarthStalkers ROM, he was able to pull the AT&T carrier files.
The N920T & A are the same. If you had bought the N920I you might lose bands.
Does anyone know where I can get a band 12 coverage map? I can only find the LTE coverage map which doesn't specify if band 12 is used there

17 and 30 (I don't think the 920t's band 12 will work with AT&T's B17 - even though 12 is a subset of 17 (or do I have that backwards?) Possibly 29 (downlink only for AT&T) - but there's very little documentation on B29, so I'm not sure if the N920A supports it or not.

Could you be so kind as to translate what that will mean to me? I have a t-mobile note 4 here on att and it seems to do fine.. Do you think I'll be so lucky with the note 5?

Band 29 is rarely used by AT&T (only as a downlink in heavily congested areas.) This shouldn't be a problem.
Band 30 (WCS band) is something AT&T _just_ started deploying, but I've never seen it in actual use. In fact, until very recently, none of AT&T's own phones supported it. B30 is really of limited value for general use due to it's propagation (or lack thereof.) Like 29, its probably only used as a supplement to other bands. I wouldn't worry about B30.
B17, however, is a Big Deal for AT&T. That's AT&T's primary "lower frequency" LTE band. Because of the low frequency, it has excellent propagation (meaning it moves farther and through trees, buildings, etc.) They use this band to cover large geographical areas with minimal towers. If you will be using your phone in a non-urban area, B17 is almost essential for AT&T. (My phone spends the majority of the time at my home on B17.)
I haven't heard of anyone with a TMO Note 5 device (without explicit B17 support) attaching to AT&T's B17, but that doesn't mean it won't work. However, Unless someone confirms B17 functionality on the n290T from actual use (and not just what they think), I'd suggest assuming that it won't work.

An informative post if ever there was one indeed.
What app do you use to determine which hand your phone is connected thru? I have found this app "LTE discovery", and it seems my att note 3 stays connected to 5 mostly, or 4 for lte. But then for GSM is doesn't list a band, but appears connected. On her t-mobile note 4 connected to att, she stays on 5, but the GSM doesn't appear to be connected to anything..
We will be almost exclusively in the middle of a city, but as with anything that could change or in the event of a road trip..
Is there a place I can sit and study this information? Perhaps a website with all of this data? Or do you happen to work in the field?
In a sea of noobs, an informed person is a real diamond in the rough - I appreciate your time.

That's a good app to use. I also use my phone's diagnostic menu's, but I doubt AT&T left those enabled on the 'a' variant.[/QUOTE]

Is that with "lte discovery" that she doesn't appear to have any GSM side connection? She most likely does, as that's where voice calls will take place...

Google. Then google some more. If you run out of pages from google, use another search engine. All the information is readily available - it just takes time to find it all.

so i got through all the hoops.. don't have LTE ;-(
it connects to band 4 or 5 when i first come out of airplane mode, but it jumps right back off. stuck on 4g. called at&t for an hour, they said initially it wasn't provisioned on my sim card, but then afterwards they determined it was a problem on my end, walked my thru APN settings and then ended the call.. still no LTE.
do you have an opinion of what i could do?

Quoting me in a thread was enough... didn't have to also PM me...
@TEKHD has a firmware that might work for you. Check it out over here: http://forum.xda-developers.com/tmo...h6-tekxodus-n5-urv1-00-00-lollipop-5-t3201869
He has apparently provided a mechanism that is working for other AT&T users... (probably via loading the AT&T RIL libs.)
I haven't tried this (and I don't even have a 't' variant myself.) On the other hand, a quick search of that thread seems to show that other people are having successes with AT&T sim's on 't' variant devices.
Good luck!
Gary
sorry about the double.
after a precursory examination, idon't see exactly what you are talking about in his thread..
is it a download?

i've searched the entire tmo dev section for term "at&t" and there are sparse hits; there is some conversation about CSC for a guy in canada getting his VoLTE working, but nothing on att.

Apparently, you already found it: http://forum.xda-developers.com/tmo...on-1-aroma-t3212091/post63516726#post63516726
This has AT&T RIL's in the update.zip, and from a quick look at the first post in that thread, they are installed based on an aroma installer. Others in that thread claim it works for them. You're using a TMO device on ATT, so you have to expect some level of incompatibility. There are AT&T LTE bands that the TMO device simply doesn't support. It doesn't matter what happens with your Note 4. Different device and different modem.
So, if you want to use a TMO device on ATT, you'll have to make some sacrifices. Most people will find the sacrifices are less drastic using an international version of the phone. For some reason, US carriers go out of their way to ensure their devices are incompatible with each other.

ok this is where i started, by flashing the ATT option for this rom. but that doesn't solve the problem. i'm in the process of clean flashing the tmobile choice like he suggested.
thanks for all your help.
i'm afraid this isn't going to work either. i realize the wife's note 4 may have different hardware, and isn't a good reference.
i can see the thing connect to band 5, then band 4, lte .. but it's in "emergency calls only" mode, then it gives up on that, connects to HSUPA or HSPA+ and that's the last of an LTE connection.
i feel like it would connect if it could, and that i'm having a software issue.
problem solved guys sorry for the large headache..
Solution:
AT&T did not recognize my IMEI as being LTE capable. Because of that, they decline to allow my phone to connect to LTE. My phone would connect to an LTE tower (as in the screen shots a few pages back), but wouldn't receive anything back from AT&T, so it would say "emergency calls only" and then give up after about 10 seconds, and then never go back. Crap data all around at this time.
What you'll need to do is walk into an AT&T store, take a picture of the IMEI off an LTE phone, and then call in and change your IMEI to the phone you found. This will cause the system to recognize your phone as LTE capable, and like magic, you'll have LTE.
I can confirm that I have a tmobile branded unit that attaches to band 17. It isn't as frequently as on my note 4, I'm generally on band 2. With that said I've had virtually no trouble with service. I was initially worried about the b17 issue, but it hasn't seemed to make any difference.

Does it attach to band 17 on AT&T or t-mobile?
Hi folks,
Just wondering: been trying to use LTE Discovery, which is mostly working, but it doesn't seem to want to show the LTE band I'm using.
Has anyone managed to get this to work? Or got an alternative app that will do the job?
Thanks.

Same issue
I asked the same question a while back for the same issue. I am not sure why the app doesn't work. I am on tmo-us and it would be nice to know whether I am on band 4 or band 12.

Hmmm random that nobody seems to know why. Bumping in case there's someone with a clue here.
i compared sprint LTE frequency band with the one deployed in my country using frequency check.com and found out they're not the same, hence i can't register on the network when i choose lte on my A9 :/
i was wondering if there's a way to edit/add the network bands i'm lacking without converting it?
Is there any method similar to this but for the A9: https://forum.xda-developers.com/showthread.php?p=61352157
i managed to run this code ##3282# which brings up the EPST menu and from there i can see what LTE band my phone is exactly running (25/26/41) and their priority 25>26>41 which is clearly not the one i'm in need right now. also i've read that it's possible to get the MSL code using a logcat but don't exactly know how to ?
folks, any help? highly appreciated.

It is build I to the ruu, just convert, it makes life easier, and data backups should be compatible.
i'm trying every kind of possibility and consider conversion as a last one.
UPDATE: i downgraded my firmware and with the help of stifilz i was able to enable DM mode,now it works like a charm :highfive: i used DFS to read LTE bands (results are attached) and they're way more than 3 i activated the band 3 which is what i'm looking for but it only remained on #6828 after reboot and didn't seem to work. i also QXDM as well but it's a lil bit tricky, you have to manually write the right numbers for your bands :/
now, can i just uncheck all the bands, since i don't really need them and leaves only one (band 3)?
after sooo much hassle, i was able to finally enable different lte bands and having them enabled permanently both on 6828 and 6829 but unfortunately it didn't seem to be working which is strange since the chipset is able to handle the band 3 with the AT&T version of the A9, why not on the sprint!!
interesting.. @syntenza you said that you're able to enable LTE Band 3 permanently, but it doesnt work?

How did you do? I can not record it somehow. when it restarts it returns to its original state.
Hello,
I haven't posted here in quite some time, but I picked up the Mi Mix 2s (Fantastic device), and the only thing that's missing to make this perfect for me, is the inclusion of Band 71 (600MHz). I've seen on multiple posts about Qualcomm phones having bands unlocked using QDXM and QPST tools. In other tutorials I see that they use an app to calculate the proper NV values, but I can't seem to find one that goes beyond Band 44. Does anyone know of a manual way to calculate this value, or another tool I could use?
Thank you much,
Blimey

I've used NV calculator and LTE Band Calculator on the Play Store.
I found this video. I can't test it until 2 weeks from now as I just started unlocking process. If you test, please let me know if it works.

By taping Lock bands then LTE all of them are checked, is that how it's supposed to be ?

I checked mine on my other rooted device. It looks like they removed the LTE Band Append option sometime between January and now. I sent the dev an email asking for more about this, I'll keep you posted.
If it turns out to be a paid feature, I think the price gouging is ridiculously too high. It's $50/week! But we'll see.

HI
This feature is not allowed to access since it’s not safe to mobile phones. Please understand…

Yes, I read about the hardware stuff regarding Band 71, but regardless, I am still curious if anyone has tried to activate it in the U12+ and the U11. I have both and travel to the US, so if either is one of the models that can use it, it would be quite helpful, however, it would be nice to at least try first and see what happens.
