T-Mobile LTE in US isn't working...ideas?

I imported the 8141 from Clove in the UK. So far, my only real issue is I have yet to see it connect to LTE. I've seen "4G" and "4G+", but no LTE...which is a problem because I can barely pick up a signal other than LTE in my area. I checked and confirmed it's using the correct APN (fast.t-mobile.com). I'm on the 110/unlimited/unlimited $30/month prepaid plan and confirmed I haven't hit the LTE cap. If I put the SIM back in my Moto X Pure/Play, it hops on LTE without a problem.
Everything I've read says the radio should support T-Mobile's frequencies. Is there another setting somewhere I need to change? Do I need to flash another region's stock ROM (and is that even possible yet)? Did I get a lemon? Do I need to hold it a certain way like whatever iPhone it was a couple years back?
Any and all suggestions are welcome.

4G+ is the UK's LTE as far as iconography is concerned. Have you done a speediest on 4G+?

I've noticed the same thing, but I (as mentioned above) thought that LTE and 4G+ were synonymous. I think the only reason to flash a region based image would be to enable radio bands that are disabled based on location (which may be in this case).

Works fine here. Lower Manhattan using same version.
4G is LTE in US.

Download LTE Discovery and you'll be able to see if it is connected to LTE or HSPA(+). Mine, also from Clove, is just fine with AT&T LTE.

You are looking at the signals wront, I'm on T-Mobile and have 4G+ as well it's the UK version of LTE. Look at my screenshot.

4G is basically the same thing as LTE in this case. 4G includes WiMax and LTE. So when you see "4G" it means you're using LTE. The same goes with 4G+ - LTE-Advanced (LTE+).
I have LTE logo on my Z3 while Z5 Premium shows 4G while using the same network.

4G is LTE in europe. We did not have that silliness that some 3,5G was called 4g. Also there is no band limitations on XZ Premium.
For app to check which band of spectrum you are connected to, please use Cellmapper app (from my signature).
If you wish to see different icon in there, you could flash Customized DE firmware which has "LTE" icon. But this has only cosmetic effect.

Instead of making a new thread, anyone knows if VoLTE works with the XZ Premium for T-Mobile?

Currently no. You need region or operator specific image Flashed (oem.sin) but there is none for XZ Premium.
But there is hope as there is t-mobile us specific modem configuration in all region images.. which will be loaded when you have correct oem image Flashed.

VoLTE and VoWIFI

Did anybody found the settings for WIFI-Call or VoLTE ?
Nothing found for Vodafone/Germany on my Z6.

No VoLTE certification on United States carriers has been the norm.
See my comment in [H]ardForum Post #10 and the response in Post#12
Has anyone, anywhere ever had a carrier VoLTE certification for their ASUS phone?

I currently own an OG Pixel from 2016 and it does not have those bands you quote in the HardForum (66, 71) and yet my Pixel operates great on my area. Are those bands important for use in your area? TMobile is my carrier if that helps any. I plan on purchasing it without a doubt.

I am on TMobile too currently running with a Moto G6. It has band 66 but not band 71 , and like your phone it runs great in my area too. However, I never have had a need to use band 66 or 71 . The only reason I mentioned the ZenFone 6 not having band 66 and 71 is some owners have the need (remote area, penetration of a building in the area where they are, etc).
What is critical for me is how will not having VoLTE affect my call quality?
Every phone I ever owned has had VoLTE as does your Pixel. For experimentation I toggled my phone's Preferred Network Type to 3G and made some calls to a robotic answering service and listened to their recordings and couldn't discern any difference in incoming voice quality when compared to 4G LTE. Incoming call quality over 2G however, sounded all muffled and terrible as would be expected.
Granted that is not an ideal way to test out call quality, better would be to make calls to different people over 4G and 3G and assess how they sound to me - and ask how I sound to them. But I have been reluctant to bug any of my handful of friends to do this with me.
My local TMobile outlet tells me that I shouldn't expect any loss of calling sound quality over their 3G network towers because TMobile is continually making tweaks to optimize them as part of their ongoing tower maintenance.
However, if you listen to what TMobile and others have to say about VoLTE it reads like this...
TMobile Support: VoLTE
VoLTE (Voice over LTE) allows you to place and receive calls on our LTE data network, and it's available nationwide.
Placing a call connects twice as fast.
Switching between 4G VoLTE and Wi-Fi Calling does not drop a call.
HD Voice on VoLTE
HD Voice is a feature that improves in-call voice quality nationwide for compatible phones.
Voice call quality is more true-to-life, with less background noise.
It automatically activates, if you and the person you're calling are both using supported phones on VoLTE.
What's your take on this VoLTE concern wreq5 ?
Would like to hear from you and others on this. In the past I've turned down flagship phones for not being able to make calls over TMobile VoLTE. And now a very attractive phone like the Zenfone 6 appears on the scene. Sure would like to have it, if only I could be assured that not having TMobile VoLTE provisioning would not be a concern.

This would not be a dealbreaker as my rural
need or getting great service in buildings is not that important but others, as yourself, do require it. As for phone calls, rarely happens for me, and I am a heavy texter so texting should be fine. The choice is yours.

I wrote above "I never have had a need to use band 66 or 71 ".

Pretty much any phone released today supports it but carriers require specific profiles for their network. There isn't a universal profile that I'm aware of. So when a carrier says your phone isn't supported or your phone does not support it, they mean that your phone isn't certified by them or have their specific network profile.
I'll admit I'm a bit uncertain on the process of getting a phone to work with the profiles in the sense that I don't know if Asus needs to do the leg work or it's the carrier. It's probably both. That's what's causing the more obscure phone models to be limited in regards to network-specific features. So if you want to ensure support, sadly you need to buy a more mainstream device.

I'm going to have to pass on this phone. Last week I contacted ASUS technical support and requested that the inclusion of bands 66 and 71 be made via a firmware update. I also asked if ASUS is planning to enable VoLTE on North American carriers. This was their response.

Hello xxxx ,
Thank you for your patience and patronage!
In regards of your escalated query, our engineering department confirms the enabling of any GSM LTE bands cannot be done within firmware since it's integrated in the hardware of the modem itself.
Also on all our current unlocked USA/CANADA Zenfones, we currently do not have support for Voice Over LTE VoLTE in our North American market at this time.

Pls can anybody check the functionality of VoLTE (wich country) and/or VoWiFi ?

Is adding bands via firmware possible? I'm unfamiliar of the tech but sounds like a hardware fix to me like they said.

Can you change LTE network band with Root?

Hi,
I'm having speed issues on OnePlus 7 using Jio. While the internet is relatively more smooth on Moto G5+.
One thing I did note was when connected to a phone call, it gets faster speeds.
I'm not sure if changing the band could affect anything.
While looking into it I came across https://forum.xda-developers.com/lenovo-p2/how-to/root-change-network-band-internet-speed-t4015883
My phone is not rooted, so not sure if it'll be able to change the band similarly.
Asking if someone can confirm.
Thanks.

Works
Rooted it myself and it does work.
Unfortunately didn't affect Jio's connection on either band.
Moto G5+ gets more signal strength than OnePlus 7 huh.

it works just "Network signal guru" app(mentioned in op link) does not support dual sim for basic users
try this
it has dual sim support for free users
https://play.google.com/store/apps/details?id=make.more.r2d2.google.cellular_pro
and make sure you take carrier aggregation into consideration while making changes to bands of respected carrier.
good luck

Question Usa carrier support

I've asked this question before and I can't find anything.
Can anybody confirm the 0/B/E versions to work on TMobile or att or mvnos of them?
If someone wants to be so kindid appreciate it. Really wanting to buy one for root.

if you use AT&T, don't buy any international models because they will block your sim. You may call them to unlock it but the sim will be blocked again after a couple days. The reason is AT&T has a list of supported models and international phones are not on their list.
T-Mobile doesn't have such a horrible thing. So yeah, it works.
Oh, and I am using 908E/DS on T-Mobile network.

That’s what I’ve done and been using till now. Bought the 908E on Amazon, unlocked the bootloader and rooted it. No custom rom for it yet other than tha Magisk rom by dr.ketan. I’ve always been an AT&T customer in so many years. They refused to work with me to make my phone work on their network so I switch to T-mobile.
I’m using the S22 Ultra 908E on T-mobile to write this right now. I don’t see any issue. If there is one, the phone is the issue.

Carrier aggregation and 5g all working well for you on t-mobile?

The missing of band 71 if using on TMO, is a big loss. I wouldn't bother.

No. I don't expect an international phone to be fully working on a US carrier network such as TMO or ATT due to missing bands. If I have to choose between slower connection and the ability to root, I'd choose the latter one. I chose TMO because it works, white ATT not working at all.
There are wifi networks available almost everywhere I go nowadays. In case there is none, usually when I was driving, 4G/LTE always available and that's good enough.

So to confirm, no signal at all for att/cricket?
What about h20wireless? Redpocket mobile?
What site to use to check compatibility? I'll take slower speeds

To confirm:
1. AT&T blocks your sim right away. Your phone turns into a small tablet. That's it. Nothing you can do about it. I don't bother with smaller companies. I only go for the big boys.
2. T-Mobile will give you slower speed and freedom of root. This comes from my experience. Very little chance I need to use my plan's data. I can't tell the speed is slower at all. As far as carrier's features, I don't use any of them, but I think you can still have them if you change it to proper CSC.
Google search your model then you will find what bands your model support. Then Google search your choice of carrier to see what bands they have. Google is your friend.

Not just slower speed. Theres some areas that band 71 would be required to even get service at all in rural areas. Like just 5 min from my house if you have T-Mobile and your phone doesnt have band 71 no service.

All depends on area. It's still missing band 71 and N71 5G. I personally couldn't as it would make my phone useless in areas I frequent

In the end, as @hyelton just said, it all depends on your area, your luck and how you would use your phone... There is no definite answer to the op's question until he figures it out himself. It works for me and I am happy with what I got but that may not apply to everyone else... If the op decides to roll the dice for a chance to get a phone that he can have total freedom over it he can go for it. Otherwise, just buy the one on Samsung website ending with U models and have all of his worries put away. Honestly, I didn't think about any of that when I placed my order.

My OP was based on the international versions because I absolutely have to have root. I have not owned a phone that I could not have root capabilities in over 10 years.
I don't care so much about 5G I just want to have a phone that functions on a US carrier from overseas. Maybe it got lost in translation but I just want to know what carriers people have and if anybody has the carriers that I mentioned with confirmation or denial of service.
Specifically the carriers on most questioned about are H2O wireless and red pocket. I'm not very Google friendly and so I'm not familiar with the bands I'm used to just buying a phone and it working as intended for my purposes.

^^^ You're overthinking it. Just pull up the bandwidths for the carrier you're looking to utilize and go from there. As mentioned you're better served by going for one of the major carriers and maybe their prepaid services. Remember major carriers prioritize their post paid plans first for their optimum network traffic followed by their own respective prepaid plans and finally the MVNOs. I would stay away from the MVNOs in your scenario if you're importing a handset not configured for the U.S to begin it and degrading it further by using an MVNO.

Question 3g connectivity on pixel 7 pro

I'm extremely disappointed and frustrated from my p7p cellular connectivity, especially 3G.
It is almost nonexistent, I tried to flash multiple roms , factory images , different carriers , rooting , with no use.
I tried using network guru to force the modem to use wcdma , with no luck .. I spotted my phone using wcdma UMTS couple of times , so there is no defect in the modem .
I'm always unreachable unless I forced it to use GSM .
Any idea how to resolve it , or workaround it ?
Can I erase modemst1 /2 and check ,or it is risky ?
Please I need help

Are you in the USA? Because 3G is either phased out or will be very soon for most networks.

I have to ask "why" are you trying to use 3G? The phone is capable of 5G and in the event that 5G is spotty you can turn 5G off and use 4G/LTE exclusively which will allow you to make calls and have data access at the same time. 3G is nearly obsolete. YMMV

I know, but here in Jordan ,3g still active for calls , volte is only provided by one carrier. And naturally, you won't be able to call using only lte coz by default, when you make a call , the phone switches from lte to 3g, and when 3g is unavailable it switches to GSM . And it's going to take long time to switch between those bands. I'm mostly unreachable by this process
So by default it's NR/LTE/ wcdma / GSM ..

Meanwhile here people have no idea what volte is and carriers dont enable it by default, i have to call them to enable it for me every time i switch a phone. 3G is still the most used network for calls there, even though 4G has even better and more stable coverage. I live in the european union.

I am only familiar with 3G with Verizon in the United States with the US version of the p7p with Verizon modem. The bands associated with 3G Verizon work well when you are outside of major cities and go more rural. But, max speeds of CDMA with Verizon bands are sub optimal at 1mbps. The call quality is great though as the old Verizon commercials "can you hear me now" reflect.
