ebay LON-L29C636B156, t-mobile USA. (upgrade to B156 yesterday, did not change anything in respect to this issue).
I can get the 4G on the home screen, but never the 4G LTE symbol. And i do not get the VoLTE menu option. I called up t-mobile support and they said that whether or not its a phone bought from them or not, LTE would get enabled if the phone supports it. So i am starting to suspect that my phone (or rather the 636 taiwanese firmware ?) does not really support/enable LTE.
My t-mobile SIM does give me 4G LTE symbol in a colleagues Honor 8 from Best Buy, T-mobile USA does not sell that. Which seems to support what t-mobile support told me. His ATT SIM does also not give me 4G LTE indication on my phone.
Given how the specs of the HW all claim LTE support for the mate 9 pro, i wonder what my best diagnostics are to determine whether or not the firmware actually enables it.
Reboot phone without any SIM inserted: "LTE cell info" app: "3G mobile technologies": Yes, "4G mobile technologies: No", "Max speeds": HSPA - aka: seems to indicate that phone does not support LTE. Same with SIM inserted, no change whether i enable/disable 4G in the system.
"AntennaPict" app, with SIM inserted, 4G enabled says LTE: -106 dbm, with 4G disabled, it says HSPA+.
*sigh*. So the diagnostics apps are inconsistent.
Was wondering what others with Mate 9 pro see.
Not sure what else i could try. Go to european firmware via Funky and see if thats any better ? (whats the number for european firmware ?).
Thanks!
Its part of the upcoming software update. Same was enabled in the mate 9.
It absolutely supports LTE. 4G is synonymous with LTE outside of the US. It won't attach to LTE networks without a SIM inserted because of the way authentication onto those networks is performed. The second app is correct.
You can check network info in about phone.
Bumping here as I have the same issue as the OP.
Anyone figured how to get LTE and VoLTE enabled on LON-L29 on T-Mobile USA...
Also, how do we get OTA update while in the US as I believe my Mate 9 Pro is an Asian Model (LON-L29636) ?
Any help here guys/gals would be super helpful. I love the Mate 9 Pro, but without these 2 **important** features it is going to collect dust on my shelf.
Thanx
Delete. Sorry answered while I was drinking and didn't read properly

Problem is you have a C636 model, which is for Asia region, not for USA. Unfortunately there is no model available under US? This was the same issue I face here in Australia - there is no AU model sold here.
From what I have seen there are only these models for the Mate 9 Pro:
Mate 9 Pro, Europe Version (LON-L29C432)
Mate 9 Pro, Asia Version (LON-L29C636)
Mate 9 Pro, Middle East Version (LON-L29C185)
Mate 9 Pro, Non-Region-Branded (LON-L29C900)
Mate 9 Pro, China Version (LON-AL00C00)
And from what I have read on XDA - there is a "cust" partition, which contains the VOLTE configuration files, which are specific to that regions Telco providers, so not having any USA configuration - the VOLTE options do not work or display to enable them... This is a major flaw with how Huawei have configured the mobile device, from what I read on forums these files are under 1mb in size, so why they have not included all regional files on each device no matter the location is beyond me.... I am stuck without VOLTE option here in Australia due to this fact, and will most likely never get it since they are not selling the device here.
The C900 being "Non-Region-Branded", sounds like this may (or may not) be a winner to rebrand to.. i'm wondering if it contains configuration for all regions!
LTE here tho is called "4G" and I am connecting with 4G and 4G+, and get the data speeds of that, but not calling (it drops down to HSPA+ when I make a call).
I have read on here that Mate 9 owners have been able to backup the cust partition and then restore it using TWRP on other devices, or most people have re-branded to their correct region.. this not possible since there is no USA or AU region build for M9 Pro.
Has dual SIM.
I'm tempted to buy and import to UK. However, not sure:
1) If Wifi calling works (I've seen online some short-codes to input into dialler). Anyone know if these work (specifically 3 UK)
2) Situation re. network. Obviously I'm pretty sure 4g will be OK but not sure on 5g (Currently 3 UK and Virgin UK/EE/Vodafone)
Any suggestions?

I'm using on Vodafone not the best network, LTE would be more of a problem with no band 20, 5g would be fine, I haven't been to 5g area to test other people in Europe have no problems with 5g
Xioami explained that the china modem and bands are quite different from Europe. With 4G you won't have B20 band and 5G antenna works differently (that's why in europe it's not dual sim).

I have had china version to test before the global.
5G in Italy didn't work very good in the china Mi 10 pro. I mean that the global version has a 25% more speed.

Is that even possible, or lockdown and heavy usage at the time of testing, side by side?
My Chinese version works fine on 5G in UK. Not sure about Italy but in UK we only use N78 5G band and the mi 10 Chinese version has that and several other bands so I'm not sure what you mean by a 25% difference in speed?
I'm wondering if we can unlock additional LTE bands in k30 Pro chinese variant for people who bought the Zoom version. I read it can be done on old devices and bands are not removed by hardware, only locked. Here you can read some examples:

I hope an expert can throw some light about this and if it can be done on modern devices.
Not having band 20 on vodafone or virgin makes no difference in the U.K. This was an issue years ago as Europe only used band 20, Europe also use band 1,3 and 7 so really isn't a problem anymore. Please search what bands your country uses, it will more than likely use 20 still but the others will also be available. I'm using the zoom model.

Well, if you're living in Germany band 20 is essential. Otherwise you won't have signal on the countryside.
So I'm also quite curious about unlocking different lte bands especially on the k30 pro zoom edition.

Same applies for Netherlands unfortunately. I might just go for the global Poco F2 Pro but I kinda want the Zoom edition lol.

the above link was posted 5 years ago, I'm not an expert but I tried every means possible on the OnePlus 3t, I was also told by people that knew more about it than me that it couldn't be done.
I tried on my old galaxy S4 never been successful
Looks like it's impossible on our phones - QPST sees the phone, but can't do anything with modem memory. Maybe because it's encrypted.
I don't really need band 20, but LTE-A band 7+7 or 7+3 is very needed. In Chinese 2020 models Xiaomi cuts off CA 7+7 support for some reason. My Redmi K20 holds LTE-A CA 7+7 easily.
Hi there, hoping someone can help with an answer;
I'm considering buying a Chinese market version of either the Xiaomi Mi 10 Pro or Mi 10 Ultra but just wanted to make sure that I'll continue to get decent 4G coverage (and hopefully even 5G coverage) on Vodafone UK.
I realise the CN version of the phone doesn't support or have band 20 which from what I've googled so far is 800Mhz.
I have no idea how phone signal actually works, so with this missing band, will I still get full coverage from the remaining bands the phone does support; B1, B3 and B7?
Does it mean that with 75% of the bands, I'll only get 75% coverage? Do certain phone masts only broadcast in B20, meaning I'd get zero 4G signal if the masts my phone uses fall into that scenario?
I'm a complete Layman with all this stuff (as I'm sure you can probably tell from the above ) so was hoping someone could help me out before I commit to spending a load of money on a phone that wont work here in the UK.
Thank you.

I don't know how Vodafone compares to Three here in the uk, but I've owned quite a few Xiaomi phones , and haven't really noticed any difference in ones that have B20 or not.

Thank you for the reply,
So some of the Xiaomi phones you've had have been Chinese import ones?
And there was no difference in 4g performance Vs global Xiaomi phones? (Just asking coz global versions do have band 20 - 800Mhz)
Thanks.
Incat said:
Yes, but I'm on Three and it might be location dependent too, but I've never had a problem getting 4g on phones with no band 20.
Check what bands Vodafone use compared to Three.
You can buy a global Mi10 Pro with band 20, though the non pro seems easier to get hold of.

That's great, I'll double check the differences in bands used between Three and Vodafone.
Finding a global Mi 10 Pro has been impossible so far, but fingers crossed......
Thanks very much again, really appreciate it.
Does anyone have an idea on how I can get 5g on my op9 ,I pay for the service and I've tried a lot of settings fiddlin ,but nothing seems to connect .maybe I'm barking up the wrong tree all together ,lots of crossed facts online about this .Is it possible ?
What service do you have?
I have OP9 5g on TMobile.. 5g works for me
5G works for me also on mine..

Go into dialer settings #*#*4636*#*# phone info and make sure Nr is selected
AT&T doesn't have the OP9 as a certified phone on their network. There is no way around this, either. I've tried everything and even selecting NR doesn't yield 5G on the device. It has something to do with the bands AT&T users for 5G.
Do you get the 5G symbol or does it just stay on LTE?
You might be able to change "carrier_policy" using the Qualcomm .exe and QTSP .exe on the computer.

This right here. As a former AT&T employee (corporate office, not retail level), I can tell you that it is most likely that the handset does not use the same 5G bands as AT&T.
AT&T primarily uses the n260 band (39GHz mmWave) and the Global OnePlus 9 does not use that band. In fact, none of the models of OnePlus 9 use n260. Now, from what I understand, AT&T *does* provide low-band n5 service in some areas so it IS possible that some users may report having 5G service on their OP9, but it's purely because they're in a low-band n5 area and as soon as they move into a more populated area where it switches to n260Go to and see,their phone will drop back to LTE.
What I can tell you from my real world experience is that 5G is really nothing to write home about. I live in one of the largest markets in the US and 5G is really not any faster than LTE most of the time. In some cases, it's actually SLOWER.

The LE2115 OnePlus 9 has AT&T's low band and C-Band 5G bands, with no mmWave, the LE2125 9 Pro has all of AT&T's 5G bands yet AT&T does not want to whitelist it for 5G access on their network. Verizon certified it for their 5G (OnePlus 9, nationwide 5G, and you can use QPST to enable C-Band on the 9, OnePlus 9 Pro, nationwide 5G, you can use QPST to enable C-Band on the 9 Pro, and mmWave), why can't AT&T?
