Note 4 - TMobile 700Mhz LTE Band 12 Question - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

I live in the Twin Cities and according to the 700Mhz map, T-Mobile has deployed Band 12 in my area. Is band 12 supposed to be faster and better? Or is band 12 just to help penetrate buildings and cover rural areas?
I'm debating if a phone upgrade is in order based on Band 12 feature.
Thanks!

To my understanding Band 12 is suppose to just help penetrate building so that you can maintain a signal. I would have posted a link for those also wondering about this subject, but since my profile is new on XDA, I can't post links yet

Any way to know what bands are in the area?

Does anyone know any way to check what bands exist in my area? I seem to only connect to band 26 (800Mhz) but my city was one of the first to have clearwire so band 41(2500 Mhz) infrastructure has to already be around. And band 25 (1900Mhz) is the back bone of sprint's lte... so I cannot believe my city only has band 26... Any way to check with some sort of band specific coverage map or tower specific information map?

Which Note 4 Exynos version works with USA T-Mobile LTE?

Folks,
I have looked for this answer everywhere and do not seem to find an answer for it: Which version of the Note 4 Exynos works with T-Mobile LTE?
From a post I read, seems that the SM-N910C sold in Qatar works, but I am not sure.
Any help is greatly appreciated !
Cheers,
G
Interesting...unless the Qatar version supports 1700MHz band....I'm don't think you'll fully be able to utilize the TM network.
This makes me curious now...
This is what I found, from XDA:
SM-N910T(Qualcomm Snapdragon 805)------[USA T-Mobile]------{FDD-LTE+WCDMA+GSM}
SM-N910T1(Qualcomm Snapdragon 805)------[USA T-Mobile]------{FDD-LTE+WCDMA+GSM}
Now, for models with Exynos:
SM-N910C(Samsung Exynos 5433)------[Asia,Europe,South America]------{FDD-LTE+WCDMA+GSM}
SM-N910H(Samsung Exynos 5433)------[Asia-Pacific]------{WCDMA+GSM}
SM-N910K(Samsung Exynos 5433)------[Korea KT+]------{FDD-LTE+WCDMA+GSM}
SM-N910L(Samsung Exynos 5433)------[Korea LG+]------{FDD-LTE+WCDMA+GSM}
SM-N910S(Samsung Exynos 5433)------[Korea SKT]------{FDD-LTE+WCDMA+GSM}
SM-N910U(Samsung Exynos 5433)------[HongKong,Taiwan,Australia,New Zealand,Chile]------{TDD-LTE+FDD-LTE+WCDMA+GSM}
I have read somewhere here in XDA that the SM-N910H will not work in T-Mobile. Then is only:
SM-N910C(Samsung Exynos 5433)------[Asia,Europe,South America]------{FDD-LTE+WCDMA+GSM}
SM-N910K(Samsung Exynos 5433)------[Korea KT+]------{FDD-LTE+WCDMA+GSM}
SM-N910L(Samsung Exynos 5433)------[Korea LG+]------{FDD-LTE+WCDMA+GSM}
SM-N910S(Samsung Exynos 5433)------[Korea SKT]------{FDD-LTE+WCDMA+GSM}
SM-N910U(Samsung Exynos 5433)------[HongKong,Taiwan,Australia,New Zealand,Chile]------{TDD-LTE+FDD-LTE+WCDMA+GSM}
And found this on the N910C:

The authority on operating bands in the US is the FCC.
https://apps.fcc.gov/oetcf/eas/repo...ame=N&application_id=544347&fcc_id=A3LSMN910C
https://apps.fcc.gov/oetcf/eas/repo...ame=N&application_id=396270&fcc_id=A3LSMN910U
Short answer, The N910C and N910U has Band 4 LTE. Neither has band 12 (700MHz Block A)
Also, when on call or in a low-signal area, hold the phone with your left hand. The diversity receiver (2nd antenna) is right beneath the power button.

Yup, thanks a lot ! I was getting to that conclusion... T-Mobile uses Band 4 (AWS 1700/2100 MHz), which you are right only the N910C and N910U have. And also true, as with other international phones like the Sony Z3 and others, the biggest regret will be Band 12. However, for what I have read, the regret there of not having Band 12 is WiFi calling and some better reception indoor like in buildings and such.
Cheers,
G.
LTE Band 12 has nothing to do with WiFi calling. WiFi calling, in terms of hardware, simply requires WiFi, which all N910 models have (2.4 and 5.xGHz). The rest is carrier support (which T-Mobile has) and software on the phone (which if it isn't on by default can be added via root).
LTE Band 12 doesn't matter much outside of California, Florida, Texas, New England, Cleveland, Denver, Detroit, Atlanta, Minneapolis and Indianapolis. Leap (Cricket) Wireless owns most of the 700MHz Block A spectrum in America. Check out this map and see where you live vs what your carrier holds.

Thank you very much.
I looked at that map but did not quite understood the results. So, can you please educate me on what really I might miss should I go missing the Band 12 for someone living on those areas you have mentioned above?
I am tired of waiting on the T-Mobile Note 4 availability and the N910U seems to be available on eBay, plus it has the Exynos.
Cheers,
What's so special about the Exynos processor over the 805? The 805 in my Note4 is a beast.
Edit: http://www.androidauthority.com/galaxy-note-4-exynos-5433-vs-snapdragon-805-395820/
The Exynos is faster. Got it.

How do you add wi-fi calling via root? My understanding is that no one has managed to extract wi-fi related software pieces from T-Mobile ROMs and successfully port anywhere. That's why I'm always stuck with TW ROMs.
Just get the sm-n910t. Why do you want Exynos version? Many app wont take advantage of that cpu.
Yup, I did. Was trying to find alternatives since the Tmobile version seems so scarce and difficult to get...but, finally got one. Cheerrs. G.
N910C VoLTE and international dialer questions.
For anyone that has the N910C running on T-Mobile, is VoLTE actived for you? When you make a call, does it stay on LTE or does it drop to 4G (HSPA) and then go back to LTE after you hang up.
Also, does the dialer include the video chat icon on the bottom left and is there a way to remove it since (I'm guessing) it doesn't work.
I have a n910c and I'm on tmobile when I call it drops down to 4g then goes back to lte.

Does HSPA (aws) 3G/4G (H+) work on your 910c on tmobile?
Also are you able to make calls & use data at the same time?
Edit: nevermind just read above post. Please disregard
Can anyone confirm for sure if they're able to surf the web or do any data related activity while on a call with their sm-n910c? I have ZERO data connectivity while on a call and as soon as the call hangs up, I instantly have my data back. Any help or confirmation is appreciated.

Carrier aggregation status on Verizon

I tried a search and couldn't find how to check to see if carrier aggregation, CA, was enabled and see what bands were actively selected for it.
Does anyone know how to see if CA is enabled and what bands are active for it? In my area I have band 2, band 4 and band 13 live for VZW. Would be interesting to know if CA has been enabled. I know that it's supposed to be live for 4+13 but for some reason my phone is always camping on band 2 in my area unless I move up a mile or two and then it switches to band 4.
I've used LTE discovery but all it shows is just Band 2, band 4 or band 13 being selected and not if CA is live.
For reference I'm located in midtown west NYC.
Thanks!

E6553 T-Mobile Band 12 support

According to the whitesheets the E6553 is supposed to support band 12. However mine never seems to use it. It's always on band 4. I'm in the Houston area, and its supposed to have rolled out here already. Does anyone else have a E6553 and actually have used band 12?
Oh and I'm using LTE Discovery to check.

Thanks, I was driving around and noticed it use band 12 finally. I guess only a fraction of the towers have band 12, and at my house and work there's only band 4. I wish they had it at work though, our lunchroom has really bad signal penetration...

Ya sadly where I've moved to in NJ has horrible LTE coverage
It only switches to Band 12 if you are inside a building where it can't pick up a Band 4 signal or if you are in an area where there is only a Band 12 LTE signal.

Has anyone tried enabling bands with QPST?

I have a question for all the lucky ones of you who have a Mi Mix.
With most of the Xiaomi phones which are released, people are unhappy about the lack of band support for regions outside of China. I know many people in Europe are unhappy about not having Band 20, those of us in Japan would really like to have UMTS Band 6/19 (among others), Australians want LTE Band 28, and people in the US would like Band 12/17.
As you may know, with some phones, it's possible to unlock these bands by putting the phone into diag mode and using Qualcomm tools like QPST. Here in Japan, it was possible to enable the UMTS Bands 6 and 19 on the Mi5 and the Mi Max, but not possible on the Redmi Note 3 or the Mi5S, so it's really case by case.
Seeing as that the Mi Mix is a concept phone people are crazy about all over the world, I am very curious whether it's possible to enable LTE bands and WCMDA bands on the Mi Mix. I don't want to spend the big money to buy one without first having confidence that I can get it to work on my carrier's bands.
So I'd like to start this discussion. Has anyone tried anything? Successes, failures, please post them all!

This (QPST) is something I have no experience with,but,interested in the subject:
I'm good with the band support (for now) as what's available in my area,with my carrier,is supported (Bands 2 &4 on T-Mobile US,no Band 12 or 66 yet),definitely would be nice for at least Band 12,if possible,as I believe my area will get it eventually.
One side note & a positive one at that:
My MiMix locks-in on a signal & has better/stronger connections than any phone I've used to date. This was really noticeable while commuting back & forth to work today,unbelieveable signal quality.
IDK if the ceramic body is better vs other materials,but,recent flagships from HTC/Samsung/LG pale in comparison vs this phone.
i have MI MIX in hand.
I think we need MIX Diag Driver to make it recognize from pc. MI5 Diag drivers are not the same

I've heard the Mi5 diag drivers were usable on the Mi5S, which is the same SD 821, so that's strange. What happens when you put it in diag mode and plug it in? Can I see a screenshot from device manager, or some evidence of what the device is?

I've got one in hand in the states (where I actually do need to unlock band 12 for T-mobile) and a patch cable I made handy in case this thing goes brick mode from us trying stuff, I'm game to be the guinea pig for science.
Fair warning though, while I'm a web developer that's very comfy with terminal, I'm new to the android ADB world, so pretty detailed instructions / links to guides will be needed ha!
Good luck Ken, I hope you are able to crack this bad boy.

Yes....was just giving the bands and frequencies I know for two GSM carriers in the US. Monitoring the bands at various locations by something like signal check lite (much easier to use/read than lte discovery IMO) would be only way to tell.. If I recall correctly this device has 3g at 850,900,1800,1900 so there is no band 4 on 3g it seems... Although band 4 (1700/2100) COULD be a 3g band too for some devices. Someone with better knowledge can chime in here. I might be wrong.

Update: I have actually successfully forced band twelve with NV values (I can see it stick and unwind the value to see that band 12 is allowed after a reboot). I followed about 10 diff guides to get my bearing on working with the Qualcomm editors and maintenance programs.
Sad to say: the modem in the Mix simply won't do band 12. I talked with a few folks from the Xiaomi Reddit Discord and they confirmed my suspicions that with Xiaomi (with a few exceptions) it is usually hardware that's keeping you off of a band.
I don't personally think there's any amount of software hackery we can do to get bands unlocked.
Edit: I am quite comfortable in ADB / SU and am happy to try any and all suggestions out on my phone in addition to what I've tried already btw. Please do let me know if there's something you think I may have missed following the various unlock threads.

Sorry to hear that the band could not be tapped into...
yes most likely a hardware thing-like Samsung (some of their models exclusively for Latin america have u.s bands but the 'international' variants of the same models will not do the U.S bands no matter what...
I actually opened one of them (got a damaged T239M) and found indeed that the motherboard is different...(so much speculation and folks asking/trying to flash S. American firmware on like the T705, T239 etc, myself included (not possible anyway even if going through TWRP and flashing modem files etc...bootloader and pit all different..so nothing would change with the other parts of the firmware)
so it is highly likely in this case that the modem will not do bands 12, 17 (ATT) and 29, 30 (ATT). However, it is impressive that for a China phone this will even do bands 2, 4 and 5. Huawei models (again supposedly international) except for some variants of the smaller 5-5.2 inch models (not p9, p8, P8 max, x2, t3, t3 pro, or m3 (some of these are the tablet phone types) and numerous other Chinese phones will not do anything more than 1, 3, 7 and then maybe 8 and 20 or a 28. (all useless for North America). Huawei has an M2 variant that has US bands and also on their smaller phones (certain versions)
so for the Mix, you at least have LTE 2, 4 and 5 (though of lesser importance).

Update: I have actually successfully forced band twelve with NV values (I can see it stick and unwind the value to see that band 12 is allowed after a reboot). I followed about 10 diff guides to get my bearing on working with the Qualcomm editors and maintenance programs.
Sad to say: the modem in the Mix simply won't do band 12. I talked with a few folks from the Xiaomi Reddit Discord and they confirmed my suspicions that with Xiaomi (with a few exceptions) it is usually hardware that's keeping you off of a band.
I don't personally think there's any amount of software hackery we can do to get bands unlocked.
Edit: I am quite comfortable in ADB / SU and am happy to try any and all suggestions out on my phone in addition to what I've tried already btw. Please do let me know if there's something you think I may have missed following the various unlock threads.

I would love to, it's the first thought I had when both starting a new guide and when I finished getting the phone to look for band 12.
I'm currently _buried_ in a project for work right now (it's taking my nights and a lot of sleep from me ha), so nothing soon. But it's on my list of first contributions I'd like to make to this awesome community!
Would you be able to try Band 20 ?
Thanks

So far my experience is that if the band isn't listed in those spec sheet it isn't there in the hardware (apparently a very Xiaomi thing to do). I'm finding that they rarely software lock you out of the bands, it's usually that their hardware simply doesn't support the band.
