T-Mobile bands...

I'm VERY concerned about buying this phone now. T-Mobile have only listed LTE bands 4 & 17 on their site.
International
Quad Band GSM; LTE: 4, 17; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)
What in the eff?

Des just answererd this question on Twitter: https://twitter.com/askdes/status/581568102015569920
It has:
GSM - 850/900/1800/1900
UMTS - B1/B2/B4/B5
LTE - B2/B4/B12/B17 with CA + B3/B7 roaming
This is the perfect T-Mobile phone.

So the T-Mobile version does not have 1700, and is therefore identical to the other models? Do we know if it includes wifi-calling, or if we would be able to flash the T-Mobile ROM onto the unlocked dev version?

But doesn't the AT&T, Unlocked, or Dev model include all of those bands and then some?

It does have 1700! That's Band 4, and for both LTE and HSPA.
The T-Mobile version also supports WiFi calling and texting. I have no idea if the T-Mobile firmware can be flashed to the unlocked version, but I don't see why it wouldn't be feasible.

T-Mobile (Des) confirmed: 2, 3, 4, 7, 12, and 17
AT&T lists: 2, 3, 4, 5, 7, 12, 17, and 29 (adds +5 and +29)
HTC Dev & Unlocked versions (per HTC on Twitter): 2, 3, 4, 5, 7, 12, 13, 17, 29, 30 (adds +5, +13, +29, +30)
Maybe the T-Mo phone supports more that could be unlocked, who knows. The extra bands aren't useful to me.

Sorry, but I just want to clarify.
Do all versions of this phone support BAND IV UMTS or not?

HTC has done this on the past couple of phones. Only the T-Mobile phone will do their specific bands (HSPA+). On past models I don't recall anyone getting the ATT/DEV models to work with those T-Mobile bands. I don't believe we ever found out why. Some speculated it was due to cost to license all the bands, or that it is actually different hardware. The M7 and M8 were both like that.
If you are on T-Mobile, I'd get the model specifically for them.

Oh yeah I remember my Dev version being like that. Fortunately, I live in an area that has been upgraded to mostly lte. This was actually beneficial for me and maybe others in the same situation because it actually saves battery life when the phone isn't constantly switching between edge, 3g/+, and lte. I'm sure many others have been in an area that's barely out of lte but still within h+ range and it's still slow as edge or even slower.

Yes, it is OK if you live in a major area that has lots of LTE. Here just north of LA, I get into the other bands pretty frequently.

I am not sure this was answered? Do all versions of the HTC one m 9 support band 4 UMTS? Many ATT carrier unlocked models are for sale and no one seems to know if they will pick up the UMTS 1700 band 4 on T- Mo?

They will not pick up the T-Mobile specific bands, which use 1900/2100 for 41bps speed. They will work with the T-Mobile LTE band.

Wow, still a mystery. I have the AT&T SIM Unlocked One M9 and I have a TMobile prepaid SIM and get Edge, 3G, 4G, LTE Band 2,4,12...I cannot find an app that shows the actual WCDMA (4G) Bands ? But, it notates 42 MBPS when it says HSPA+ 4G using Network Signal Info-Pro App..and also shows 384 Kbps when it says 3G....
So, seems Des is correct unless the Network Signal Info Pro app is wrong?

I turned off everything except WCDMA, and this is what I get being reported by LTE Discovery. HSPA+ @ -113. I have a ATT unlocked M9. I do have the T-Mobile 2.11.531.19 firmware installed as well as the T-Mobile rom.

Thanks but as I mentioned I cannot find an App that shows the WCDMA Bands to confirm. As you can see even LTE Discovery says N/A for DL and UL Freq...when on WCDMA...
The only App I can see that helps is Network Signal Info Pro...and unfortunately it is limited and shows me the below in my market;
HSPA+ 42.2 MBPS
HSDPA 7.2 MBPS
UMTS 386 KBPS
But, does not indicate which Band or Frequency ?
Anyone know of an App or Command that will show WCDMA Bands???

[Q] M919 LTE band confirmation please

I have two M919 phones: The T-Mobile M919 and the MetroPCS M919N. They are the same phone with different branding I believe and have used both with the same flashing software, dialer codes, replacement hardware parts, etc.
I unlocked both phones as detailed in my thread in this forum.
What I need is: In the Band Selection Menu, What is default for LTE Band Preference?
I dialed *#2263# to access the menu. I have an asterisk next to Automatic in one phone and nothing in the other.
Under LTE Band Preference, I see 9) LTE ALL selected. What is the correct band to chose for T-Mobile LTE on either a T-Mobile or Metro branded Galaxy S4 M919?
Thanks much

Band 4

Thank you very much.
In my area T-Mobile just rolled out Band 12 (700 Mhz), but this band does not exist in my phone's configuration. How about yours?

BND-L24 USA LTE Bands question(s)

Reference phone specs at end. I recently got the Honor 7x and am using T Mobile in the Atlanta, GA US region. At home, when I got the phone Friday night after work it was awesome. Super fast no problems plug and play. But Monday at work I get full signal, but no internet. No download speed. I found that when I go into the settings under mobile network if I choose preferred network mode down to wcdma/gsm it turns off the LTE but I get some data. Is there a way to remedy this problem without having to sacrifice LTE while I'm at work?!? I know the Huawei website says the phone works with T Mobile, but if it only works with 3/5 bands do I just not get LTE where those bands are in effect? Can someone shed some light on this? Because before today, I honestly didn't know what any of this meant. Thanks in advance!
Phone Honor 7x
Model BND-L24
Build Number BND-L24C567B140

Miguel EsquivelHi there! Thank you for reaching Honor Device USA. How may I be of help today?
Sam8:40 pm I'm having trouble with my signal for my phone, and I'm also having a difficult time finding information on my situation with the US version of the 7x. I have L24 version, and I also have T Mobile. am I unable to get 4g?
Miguel Esquivel I see, let me help you with that
I am sorry you are havinf this issues Sam
Can i please have your imei number
Sam ...
...
Miguel Esquivel Thank you just a moment please
Thank you very much for holding Sam
Sam of course
Miguel Esquivel Can i please know who is your carrier?
Sam t mobile
Miguel Esquivel Thank you
Can i please know what issues are you having regarding the carrier signal?
Sam well, when preferred network type is set to LTE/wcdma/gsm auto and 4g is enabled, i get a full signal as far as bars go and the 4g icon is there but my download speed is nothing and it tells me im offline
when i change preferred network mode to wcdma/gsm i get data, but not 4g
Miguel Esquivel I see
Have you try a diferent sim card?
Sam sim card works in other phones fine.
Miguel Esquivel Thank you for that information
Does this happen everywhere?
Sam mostly seems to happen when I am at work
i work in...
live in...
Miguel Esquivel well it seems to be intermittent issue, but since your satisfaction is our main goal we can send the device to our repair center for further testing, but if you allow me to add my opinion i think that the signal goes weeker on that location and probably does not reach enough power to have data traveling on it
I do not have a coverage map for your carrier i am sorry, but you can consult them, it could also be a sensibility related issue with your antenna Sam
Sam i'm showing that there are 2 bands that the honor 7x does not support that tmobile does use and im just wondering why we aren't on the same page
it's not a repair issue. it's a matter of whether or not the phone is compatible, and i'm leaning towards no unless you have a solution. there are 3/5 supported LTE bands for this phone which i did not think would mean that LTE wouldn't work at all
Miguel Esquivel This are the frequency bands compatible with the L24 A
Primary SIM card:
4G LTE FDD: B2/B4/B5/B7/B12/B17
3G WCDMA: B1/B2/B4/B5;
2G GSM: B2/B3/B5/B8
Secondary SIM card (voice services only, no data service):
2G GSM: B2/B3/B5/B8
Sam so if T mobile uses B66 and B71 LTE bands for their LTE service as well and the honor 7x is incompatible with these my phone will not work properly unless i completely turn off LTE????
Miguel Esquivel I am afraid the service could be intermittent Sam
Sam so depending on where I'm at, I need to stop what I'm doing go to settings and turn off LTE data in order to get ****ty 3g data just so I'm not stranded? Read
Miguel Esquivel I am sorry Sam
Miguel Esquivel has closed the chat.

Lte does not work for me in Canada with freedom mobile too.. Honor and waway does not give a **** as usual

Okay, forgive me for this, but what was advertised that isn't working?
T-mo will be the first to tell you that not all of their services are available everywhere, is that what's going on here? I may be missing something here, but does the honor / huawei not work when a different device (with the same bands) would work?
Honestly, just a question, I really don't know...

Lte band 4 and 7 were advertised and does not work on my carrier..

the same problem here. i'm in venezuela, band 8 UMTS were advertised on the specs phone and doesnt work

The 900 band you want to use isn't available on the BND-L24 model

Works great on at&t even in areas near here that have gotten worse service recently.

Bands 5 and 12 are the main T-mo bands so it should work for you, bud. I would double check the APN. I would also have T-mo release the SIM and reprovision it (cut it loose from the network and reconnect it); I used to work for T-mo and this can resolve a buttload of connection issues.
I use mine on Cricket/AT&T and get better reception than I did with my ZTE Axon 7.

Unlock Mate SE frequency bands

Is it possible? I'm with MetroPCS and get about 80% of their frequencies but I'm short a few bands. Anyone on the same boat as me?

I'm with T-Mobile and the phone works great with no band issues-even better than my S7 edge Tmo.

I know MetroPCS uses their network. Have you done the frequency check to see if you're getting all their bands, for t mobile I mean? I have attached the bands that the mate supports on Metro but would like to enable the ones that aren't.

I don't think the Mate phone (or any honor 7x version) have the hardware capabilities for band 66 or 71. If the phone was exclusively for T-Mobile, I bet Huawei probably equipped at least their flagships with them. Below you can see all the supported bands from all the Honor 7x versions.
https://www.gsmarena.com/huawei_honor_7x-8880.php#l24
For me, even if the phone had either band 66 or 71 dunno if T-Mobile have deployed these frequencies where I live. I either get band 4 or 12 and is incredible fast (100 Mbps download).

ugh i totally want to know how to unlock all those bands
This phone becomes useless when you travel to Europe especially with LTE as major bands used in Europe aren't supported on US models.
this is very frustrating.

Unlock additional DR (5G) bands?

Hi all,
I'm wondering whether it is possible in some way to unlock additional NR bands on the S20. As far as I understand the Snapdragon 865 chipset, it comes as a fully-fledged 5G mobile platform which can be used in all countries and which supports all possible NR frequencies/bands.
So, it seems to me, that Samsung just locks off the majority of bands in the different models (for example, I got the G9810 and like to use it overall in Europe. However, Samsung only delivers the bands N1 and N78 but not e.g. N28).
Would be great if anybody could give me a hint about this.

I think there is no way to add more bands because these are defined to hardware. But i'm very interested about your model 4G Carrier Aggregation Combinations. These can get from log file: https://mt-tech.fi/en/how-to-get-4g...ons-from-your-android-phone/#Qualcomm_devices . Could you please share to me this BandInfo file? You can send this to https://cacombos.com/contribute

check out the Samsung Band Selection app on the Play Store. Supposedly, it can unlock hidden bands.

I looked at it but I'm unsure which bands are available to Sprint/ T Mobile in the St. Louis area. I set to Automatic. Playing it safe I guess .
Also when I switch to 5G it doen't show any bands. The S20 + is capable of more 5G bands I hear

Only can disable/enable bands what hardware support. If it doesn't you can't just randomly unlock bands.

What model Samsung S20+ you have? From modem logs you could export some data what your phone support: https://mt-tech.fi/en/how-to-get-4g...ions-from-your-android-phone/#Samsung_Devices
