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.
Using XDA to unleash the power of Android on my HTC One M9
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???

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.
Any reason why my Pixel 2 XL will not connect to Verizon's Band 4? I get all of the other bands, but not Band 4.

How are you determining which band your on?
Not trying to be sarcastic, I am truly curious. I too am on Big Red, but couldn't tell you what band I'm on
@Badger50: Answer to your question is at https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery&hl=en_US
@BuffLG: Verizon's band 4 may be widespread but it is used to provide added capacity to the network. If the cellular traffic in your location isn't heavy enough, you may never see band 4 even though the P2XL supports it.
I use Signal check to see the bands. Or LTE Discovery.

Much obliged kind sir. I do know/remember that I'm usually on band 13, but was curious to know how to check it. Thanks again :good::good:
Lol with LTE Discovery it says I'm on ATT band 12, while signal check shows band 17.
Sent from my SM-G960U using Tapatalk
Signal Check Pro easiest way.
Band 13 is Verizon's original LTE band has furthest range (700 mhz spectrum). Band 4 (1700 mhz) and 2 (1900 mhz) are their AWS spectrum.
Band 2 also has the highest capacity. Usually deployed in the most congested areas first.
Band 2 will technically be the fastest. Will probably be the hardest to connect to, but if you're close enough to a tower and getting Band 2 service, you're golden. I've seen speeds close to 100 MBPS on Band 2
I'd bet a nickel you're not seeing band 4 because of this bug: https://issuetracker.google.com/issues/37136986

Reading through everything, most people are having issues with T-Mobiles LTE band 66 showing up as band 3.

This bug is relevant on Verizon, AT&T and T-Mobile but not Sprint (I believe) as they don't have Band 4 and/or 66. T-Mobile turned on MFBI at least several months (maybe a year?) before Verizon and AT&T did.
Again I don't know for sure if it's related to what you're seeing but it does "smell" that way. Band 4 in the Phoenix area almost always shows up as a Band 2 EARFCN that Verizon doesn't own when using Signal Check Pro as it is being reported incorrectly by Android. The EARFCN is correct under the same conditions using Network Signal Guru since it reads directly from the Qualcomm chip.

I always got band 4 until the last couple weeks .. I now get Band 3 instead of band 4 which seems to be faster if I get a strong enough signal.. Band 3 doesn't seem to be as strong a signal as Band 4 though.. Band 4 was always displaying as XLTE where Band 3 displays as LTE.. my old Moto Pure still gets Band 4 so I really don't understand why the Pixel no longer will get it! Got to be by design by Verizon, me thinks!!

That's the exact issue @turboencab is talking about. There is no Band 3 LTE in the USA. You are seeing Band 3 because of an Android OS/Qualcomm bug that cuts off EARFCN values above 65536. Band 4 can be "displayed" as Band 66 and most operators choose to do this now. Band 66 EARFCN values are above 65536.
Tldr; there is no Band 3 in the US. You are still connected to Band 4. Apps aren't able to display the correct band due to an OS bug.
Try to use CellMapper as a tool to see what you're connected to. The devs for that app can "correct" this issue based off some assumptions. https://play.google.com/store/apps/details?id=cellmapper.net.cellmapper
Hello, I'm looking at the Global version of the Redmi Note 5 (Basically the pro. Referred to as the AI Dual camera on GSM arena) and I'll be using it in the US on Mint Mobile. Mint is a T-Mobile MVNO and I'm not sure how LTE support will be on this. If anyone has any info on this that would be great. I believe Mint mainly uses B4 and B12 but I could be wrong. I've been looking around and found mixed responses of it having good carrier support stateside and others saying it won't work.

I can confirm that the phone will WORK on B4 (1700mHz/2100mHz) and B5 if you live in the greater Myrtle Beach area. (Acquired from SunCom back in the late 2000's). I don't know if your area has B5. On your existing phone, get LTE Discovery from the Play Store and sample your most common areas first to see what bands are most prominent. Being where I live, the phone mostly uses Band 5 over 4 because of the lower freq; able to reach tougher places where the higher freq B4 can't reach.

Thank you so much for the reply. I'll give that a download and travel around. Since posting I did discover my current phone supports the same bands. So I'm less worried. :good:
Lte works on band 4, but not band 12 on T-Mobile. But, for me band 4 is enough, if I don't get lte the device will switch to 2g. 3g straight up does not work for me on T-Mobile, although I've heard that T-Mobile does not use 3g anymore in the first place.
All in all, for me lte works just as well as my previous phone (zte zmax pro)

I can see that. When B4 and B5 don't work the phone just switches to 2G but without internet so basic voice and sms still works. about 70% of the time after it switches to 2G it'll tap onto HSPA+ (3.5G, coined 4G) and I got that for a while until LTE reconnects. Rinse and repeat until I have to leave to go somewhere.
I just got a brand new international version of the G7 Thinq, it is the international version, with 128gb and 6gb ram.
I'm able to connect to T-mobile and make calls etc, but it won't connect to LTE even though I've been using LTE for years in my area with no issue on old phone.
T-Mobile support was not able to help me.
The highest it connects is 4g
I really do not want to return this phone to the seller, but I don't want to settle for a phone that can't connect to LTE like my old one.
Willing to try anything...any ideas?
Thanks
4G is LTE.

Do you have this phone and live in a LTE area? My old phone actually said "LTE" for the signal when it connected with LTE, are you saying this model phone does not actually say "LTE" on the signal bar?
Can anyone confirm that this phone says "LTE" at the top with an LTE signal?

4G *IS* LTE.
You need to google what LTE is.
occasionally you will see 4G+ (downloading).

I just googled it and I've read 3 sites so far that says they are not the same.....
https://www.tccrocks.com/blog/what-is-difference-between-4g-and-4g-lte/
I'm not trying to start an argument. I'm just used to my phone displaying LTE and if you are saying this model does NOT display LTE, and displays a "4G" instead, then that answers my question. Some sites even say HSPA+ is 4g, and I know that is different than LTE.
On tmobile he is correct 4g is hspa+.. My g7 says 4g lte when on lte.. Did you do a network reset? Or call tmobile and ask then to redo your phone activation to make sure you register on there network right.. Maybe need a newer sim?
Check the APN settings

I've called T-Mobile, had them do a restart, had them check APN, etc.
I'm using the same sim as my old phone that gets LTE just fine, so it's not that.
I'm thinking something about this international version maybe doesn't support one of the bands or frequencies that T-Mobile uses in Chicago (even though it says it supports GSM worldwide)
I'm probably going to send it back as my 3 year old Motorola phone gets a higher tested download speed on a speed test than this new one without LTE. Just wanted to check if anyone else had the issue. Thanks

T-Mobile uses LTE bands 2, 4, 12, 66, 71, while the G710EAW, which I assume is the model you've bought, supports bands 1, 3, 5, 7, 8, 28, 38, 39, 40, 41 - so none of the TMob LTE bands.
There are six variants of the G7, G710EAW is aimed at Asia/Oceania and together with the G710EMW (64GB/8GB single-sim version of your variant) the only one that doesn't support at least two of the TMob LTE bands.
Sorry, hope you'll find a nice replacement

Don't get your information from the LG website. The site only shows which bands are used IN THAT REGION, not what is supported by hardware.

Don't believe everything you hear on the internet. Bands 2 and 4 are supported.
These are the bands supported by the G710EAW.
GSM: 850/900/1800/1900
WCDMA: 850/900/1700/1800/1900/2100
TD-SCDMA: 1900/2000
LTE: B1/B2/B3/B4/B5/B7/B8/B12/B13/B17/B20/B28/B38/B39/B40/B41
If a band is NOT supported, trying to select it will show "FAIL" in the engineering menu.
Example: band 25 is shown, but not supported. This will show FAIL.
It was the international LG G6 which had problems with T-mobile, as Band 2 was not supported (shown in service menu, if you select it it shows 'FAIL'.)
I sold one of these phones (I had 2) to a T-mobile user and he's happy.
I have also the 128 GB lg g7 eaw version. My phone shows 4g also. The speed test i have done is 60mbps both up and down and i am ok with that.
What is the diffrence between 4g and 4g lte? Should it display lte?

My G710EAW shows 4G+. Uaing Net10 on band 2 which uses tmobile's servers. I think each and every person here needs to stop crying wolf. Seriously.
If the US version shows LTE and the international version shows 4G+ I mean who cares if its the same damn thing?
https://www.4g.co.uk/news/what-is-4g-plus-ee/
4G+ is another name for LTE-A, LTE-Advanced or 4.5G and it’s basically a faster version of 4G. It works through carrier aggregation, which allows 4G phones to receive data from multiple bands in the 4G spectrum.
So while standard 4G only uses one band at a time, 4G+ can combine two bands for increased speeds. In EE’s case it’s the 1800MHz and 2.6GHz bands which are being combined

The information is from gsmarena. They have been spot on with this kind of information the last times I checked. However, it seems like they're off with the G7. I just compared my variant with their information and it's off as well. Thanks for catching this!
So in that case I can only think of one reason why the OPs phone would not connect to TMobile 4G: the network in your area is using bands that are not supported by your G7. However, this is quite unlikely, since these would be 66/71. From what I read, they have only been introduced in 2017.
