Hello.
I am using Honor 8 L04 with B162.
My network is AT&T of USA. I looks like I cannot use data using call.
I remember my previous phones (Galaxy or iPhone or HTC) were okay with this.
Is this device issue or setting issue?
Could be a firmware issue that will be solved with a future update.

It's not rom or radio related, I have been facing this issue since 4G was first used in Turkey. I'm able to send sms or have access to internet, device model is D821. Anybody know something about that?

It's normal behaviour because LTE is commonly used only for data connection except your network have VoLTE (Voice over LTE) functionality.
Using Three as an operator and when calling or answering it of course switches from 4g to 3g but the connection is lost. No data connection. Anyone with the same problem?
Can it help with a new rom?
I have reinstalled the phone 2 times but no success.
BTW. It works when I have 4g off.
same issue here with my new xperia xz. with stock 6.0.1 (unrooted) and with newest 7.0 firmeware. my redmi note 3 had 300 % better lte signal. does someone have the same issue? my provider is tmobile (including LTE band 20)

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.
I m using my G930FD (Dual SIM) phone from may 2016. On marshmallow i didn t have any problem. After I switched to nougat, problems occurred with reception on 4G.
Where I live, the phone uses the Band 20 (800Mhz) and working both Sim cards without any issue, everything OK.
At my workplace LTE uses Band 3 (1800Mhz) appear the problems. After a random period of time, SIM1 unusable switch off from network and get "No service, emergency call only". Airplane switch ON/OFF, and SIM 1 functional again.
You can see the actually used channel dialing *#0011#
I think the problem is related to nougat modem, and only on BAND 3. Tried 4-5 different nougat modems, but no lucky.
TEMPORARY SOLUTION: flashed back marshmallow 6.0.1 modem G930FXXU1BPL6 and now seems ok.
Anyone else have this problem?

I'm not using the dual SIM version but the normal one (G930F). I also have some issues with 4G data dropping to EDGE/GPRS after a call and occasional "Emergency calls only" message. This would either require a restart or a switch in Mobile data type (LTE/3G/2G) and revert back for it to be fixed. I've also tried flashing different modems like you've done. I initally had the NEE region in Marshmallow (which I remember had the same issue, but less frequent) and then I updated to Nougat by flashing the BTU firmware.
I will try the modem that you have mentioned, hope it all gets fixed after that Thanks :good:
Using stock m9. Data 4g or other turns itself off when I start dialing and reconnects after I complete my call. Very frustrating when I need to search something while talking. Is there a setting I'm missing? Has anyone else noticed this?

Probably, you are missing VoLTE. Without this technology when phone using 4g and receiving call, it jumps to wcdma (3G) to get call, but drops mobile Internet in this moment.
To get everything working need:
- Mobile operator, who supports VoLTE
- Phone. Mate 9 supports VoLTE on paper, but not in all roms and not in all regions. For example, owner is living in USA, but has Mate 9 with chinese Rom -> no VoLTE.
You will have to enable VoLTE in order to get rid of the trouble.
I have the same issue also. I own the dual SIM variant and use one card for calling and the other one for mobile internet. Whenever I start a call the mobile data connection is stopping. I tried to enable VoLTE with no success.

In the latest C432 roms Huawei has removed the possibility to enable VOLTE for Vodafone Italy.
This possibility was present only in the first 2 update.

This is other case. If you are using one card for calling only, and second card for mobile internet only - you can't get call and mobile data together, cause Mate 9/Mate 9 Pro are DSDS phones (dual SIM dual standby)
To get what you want need have DSDA phone (dual SIM dual active). They are with two independent radio modules. Honor 8 for example.
Dsds phone has only one radio module but uses interchange method of work. On physical level it jumps from first sim to second then gets back to first. If you are in call with first sim, phone does not go to second -> no internet.
