No data during calls? - Huawei Mate 9 Questions & Answers

Hi Guys,
I'm using the US Mate 9 with AT&T, a GSM provider. I noticed when I'm on a call either there is no data (Internet) available or very patchy with the screen on...
Wanted to ask you guys if this is normal and expected behavior?
Thanks!

I dont think is normal, I've seen icon change from 4g to 3g to H+ when I'm on calls but still able to open facebook,whatsapp or firefox while calling. I'm with Tmo tho.

It's because At&t doesn't allow VoLTE on the Mate 9 so when you make a call you get dropped to 4g or 3g speeds. T-Mobile allows VoLTE so data doesn't change due to a call. I run both sims in mine and it's why I keep my personal line on T-Mobile and use it's data. My At&t line is strictly for work calls.

Thanks for your responses guys... In all my years of using all these different phones on AT&T, I've never ever noticed this since the Verizon days. I'll take the degraded 3G or H+, but yesterday it went straight to no data. Do you guys think I need an adjustment in my APN or is it a buried setting somewhere to fix it?
Thanks!

I didn't adjust anything with my At&t sim so I don't think you should need to either. Also this is a brand new sim and number so it was never in a different phone. I know on my Axon I had to put it in my iPhone first to get it working properly but not this phone. Are you in a good coverage area?

Are you sure about this device not doing VoLTE.

The device does VoLTE, At&t however isnt allowing it on the device. I can switch my data to my At&t sim and take a screen shot and back to T-Mobile and take one if need be.

Is the 4GLTE icon for Tmobile? I dont get to show the LTE letters but only 4G in mine, probably because is the Chinese version.

Both At&t and T-Mobile show 4gLTE icons but At&t's drops to 4g only while in a call, T-Mobiles stays 4gLTE which verifies VoLTE only works on T-Mobile.
I believe you're correct and the Chinese variant doesnt show LTE.

[SOLVED]
Guys, thanks for all your helpful responses! Just to close the loop on the issue of *NO DATA* during calls was fixed with the check box, checked in the attachment.
Although, as shared here, it's possible that it's H+ or 3G only service, not true LTE.
Thanks!

Alternative Solution
I had the same problem, I found out that this box was already checked on my phone, What fixed it for me was checking Mobile Network -> Access Point Names> selecting "ATT Phone"
I had initially selected "ATT Nextgenphone."

Disable LTE without custom ROM?

I have the ATT HOX and want to disable LTE due to the known issues with missed calls etc. Would it be possible to disable it through root access WITHOUT installing a custom ROM?
I'm not sure what AT&T do to their phones but can you not change it via Settings > Mobile Network > Network mode.

Att one x doesn't have that function. Try to do it in service menu trying typing in *#*#4636#*#*
Go to phone info and scroll down. It works for me on clean Rom but not sure about stock rom

What known missed calls issue? What would LTE have to do with missed calls? LTE on AT&T is data only. It doesn't do anything with calls. You can dial *#*#4636#*#* and try to set it to gsm only or something.

Believe me I have tried. It's not possible. But ik you said you didn't want to, but you really should look into custom ROMs. There's some that are basically stock with just better battery
Except for ATT. Its a well documented fact that they have it disabled. Any changes you make revert back to default.

Its a fairly well known issue with ATT and LTE phones.
As far as I can tell since LTE IS data only it has a hard time receiving calls when its connected to the LTE network. I think it has something to do with only having 1 antenna and it cant communicate on voice and data at the same time. Or, maybe not.:silly: All I know is that when my phone is connected to LTE I will not receive phone calls. All calls will ring a few times and then go to voice mail. I eventually get voice message notifications when the phone switches out of LTE.
Any changes made in the field test mode do not stick. Thank you very much ATT.

I've had 3 different LTE phones on AT&T and never had issues with missed calls and I'm constantly on a LTE connection. My phone kicks to hspa+ right before I receive a call and then it rings. Goes back to LTE about 30 seconds after I hang up. The only thing I can think of is that you are on LTE only in the field test mode thing. That will definitely give you call problems. What does it say that you are connected to when you go into the phone information menu?

I've had a few LTE phones too but I can confirm that this is an issue with AT&T and the HOX. (At least in certain areas.) The phone is *supposed* to do what you said and switch off LTE when a call comes in but that doesn't always happen. I've noticed it the most at my office where I usually have 4 bars of "4G LTE" or one or two bars of "4G". I'll have a long period of time with no incoming calls or texts and then when I make a call (and the phone switches to "4G") I get the backlog of voicemails and text messages. Hard resets haven't helped and AT&T refuses to admit that it's a problem.
Heres a summary of what I have found:
1 Being in field test mode does not affect incoming calls.
2. When making outgoing phone calls with LTE or HSPA displayed in field test mode, the connection will switch to UMTS and then revert back to LTE or HSPA after hanging up. I dont know what that means, just throwing it out there.
3. On a few occasions during my testing I have noticed that I could not receive calls when HSPA is displayed in field test mode. I think that the phone had just switched from LTE, although I havent been able to 100% verify that.
4. My connection at my house varies between LTE, HSPA,EDGE.
5. EDGE is great. My phone makes and receives calls all day long when I have a EDGE connection.
6. Most of my testing has been at home where I have crappy reception to begin with. On a few occasions when I had my wife with me I had her call my phone(connected to LTE). Same as when at home, my pone never rings.

Exactly!
I have Samsung Galaxy S3 on AT&T and I have same issue when connected to LTE. I have been working with AT&T CSR for over a week and no resolution yet. I have talked them into switching my data plan from 300MB LTE to Unlimited Standard Phone data plan. (Unlimited standard phone data plan uses HSPA+ and not LTE, which would resolve the issue)
From what I have understood so far, its not the phone, its the AT&T LTE network.
Wouldnt people with the same phone have more answers for you?

No, because this issue is not related to the phone but its related to AT&T LTE network. So everyone on AT&T LTE network has same issue and not only people with HTC one X.

I was on phone with them last night. They have created a case number for me so their "technical team" can look into it. They promised me to get back to me before friday on this.
For changing the data plan, the CSR tried to change it but it didnt work yesterday. I blame it on the CSR because I know some people on XDA has done that before. I am gonna call them again and have a different CSR try it or me.
And plus, with this change, you get unlimited HSPA+ for just $10.

Thanks for the link. Those settings actually worked for me. I had already tried a couple different APN configs but none of them seemed to stick.
So, now I have successfully disabled LTE.
Unfortunately, I'm still having intermittent missed calls with the phone connected to HSPA. Also, At work in certain areas, we have rock solid LTE reception and guess what...no missed calls. WTFrack?
At home the only time I can get regular calls is when the phone is connected to EDGE.
I seriously think that there must some relationship between 4G/LTE and signal strength. Does anyone know If EDGE and 4G/LTE use the same towers or same power outputs?

[Q] LTE problems?

Been on the iPhone for close to a year. I'm tagging out! Coming back to android and the ultra or maxx has been the device I've set as my decision. However I'm a tmobile user. Maxx has the battery life I need so I want to clarify before I pick one up what any glitches of the device may be on the network. I've been reading with the kitkat update there is some sort of issue with the enabled lte and not being able to utilize SMS/phone at the same time as lte data? Is this true? If so any possible way to remain on H+ without activating lte or inputting apn settings? Or has this been rectified? Lol.....rectified.
Any input anyone has is appreciated. And yes I know. I should get verizon. I've been with tmobile for 12 years. I just can't beat their price right now and I live in an lte city. When I go out in the county it's a different story. But one day I'll jump ship. Maybe intervention is required. But right now I wanna stay with the T.

"LTE Thunderbolt" on the play store will be your best friend while on T-mobile
Works wonders with moto devices, you can choose which exact signal the phone should look for (LTE included)
Great phone period. On vodafone with it right now, used that app to ONLY look for HSPA+ and everything is golden Lemme know if you have any other questions, but that app should fix ya up
Awesome thanks bud. I was a but concerned about that whole hiccup and was making me second guess getting it, but the phone seems to be the best choice for me out of any available android phone. Hopefully this will get worked out. Do you find it a little inconvenient to switch signals or do you just stick with the hspa signal permanently?

You can switch the phone into gsm only using phone info. If lte is disabled you'll be fine on KK until they fix it. LTE/GSM works fine on 4.2. I'll link a copy of phone info to make the change. Please don't modify other settings as you can potentially permanently damage the radio. You'll get HSPA+ in refarmed areas. EDGE everywhere else.

You're doin it wrong GSM only disables the LTE radio.
If I'm understanding arcanexvi's post correctly it instructs to switch to "gsm only" and not "gsm auto", though it's circled in the illustration. Hard for me to speculate though until I have the phone in hand.
Lol you beat me to it. I can see the confusion though since gsm auto is circled in the photo. It's like sitting in the drivers seat getting directions from the passenger and they say left and point to the right lol. I'll let ya know how it goes when I get the phone. Thanks bud.

how to unlock AWS

Sprint note 5 unlock full , is there a way to get tmobile 4glte on this ? I was told that sprint lock that from there phones so I have to enable aws
The Sprint Note 5 variant contains the LTE bands to support Tmobile's B4 and B12 LTE network. If its unlocked you don't have to do anything but just pop in a Tmobile sim card. Not sure what is the confusion is. In addition you have to set your Network mode to be Automatic in Mobile Networks settings.
My note 5 is unlocked by sprint. And i do not get LTE from tmobile, only 3g. When i switch to automatic, it stops working and i get a "!"
Yup but it does have 4glte capabilities, also I was suggested to try verizon but they don't have unlimited plan, at least know I get my clients photos and respond don't have to hang up and all that

XZ on Verizon?

I know this is not officially supported, but does anyone know if this will work with a Verizon SIM? I know in the past, CDMA radios were required for Calls and Texts, but with VoLTE, shouldn't CDMA be unnecessary at this point? Can someone try throwing a Verizon SIM in it and see if it will work. I'm trying to find a Note 7 replacement here. The rest of the Verizon phones SUCK.
I'm really wondering about this too. I'd jump from my S7 Edge to this if it could really work. lol
Oh yeah, if any of you Xperia XZ owners could be so helpful in using this tool from the Verizon website: https://www.verizonwireless.com/bring-your-own-device/. I think this would help see if we could use the XZ on Verizon network. If any of you guys do it, can you post screenshots (blacking out any private info if you may), I'd really appreciate it!
Verizon uses CDMA which Xperia phones so not support. They only do GSM. I suspect a Verizon sim card would not find coverage in an XZ.

But there is LTE support. If you have an XZ in your possession, can you try using the tool in the link I provided to see if it works?
To be able to use VoLTE, you will need to enable HD Voice or Advanced HD feature for your line and also the person you call has to have to same feature enabled. Both callers need to be in LTE coverage areas for VoLTE works.
So it isn't always working for you if you don't have CDMA capable phones.
Sent from my SGP771 using Tapatalk
All voice calls still go through the CDMA network UNLESS, you are on Verizon and have HD voice enabled on your phone. I
know, Verizon is still using 800 CDMA in almost every cell site. This this is so VZ customers can call other carriers..
This became very apparent a few months ago when Verizon had a CDMA network outage on the west coast and we could only call people with in Verizon that had HD Voice, no one else.
If the XZ does not support CDMA (can someone confirm?) that would mean NO "Cell Network " phone calls. Data should work fine if the XZ supports LTE 700 c, 1700 f, 1900
Kinda getting tired of this, I really wanted an S7 Active and now the XZ.
One of these days I am going to jump ship. I. just have a bit of "data coverage anxiety" is the only thing holding me back...
The reason Verizon keeps their CDMA network because they still have 3g devices which are CDMA only.

Yes but, not necessarily the reason why VZ is keeping CDMA.
3G (1900Mhz CDMA) will begin to get faced out sometime next year. This is not a secret, it's actually common knowledge. In fact, some areas already don't have 3G coverage.
(800Mhz CDMA) Voice will stay at least for 2017. This is because VZ's VoLTE aka VoIP is not quite ready to go.
Some guy already tried using a VZ SIM on a Xperia XZ, didn't work.
Search YouTube for: "Sony Xperia XZ Verizon CDMA Test"
CDMA faced out all over the world last year except VZW. Some areas do not have 3g coverage doesn't mean there is no CDMA network there. There is a lot of VZW basic (CDMA) devices in the market now.

For this guy, it could be the first time he tried unlocked phone.
At least he need to add APN settings for Verizon network first. It's not gonna work what so ever since unlocked phones do NOT have it.

If you're not connecting to a tower, I don't think APN settings are going to help you.

Of course you don't however, didn't that phone connect to the network briefly at start up, did it? Also it's only video so it can't prove xz doesn't work with VZW. It's my opinion even though I'm not with VZW.

Just to be clear; that's not my video. I'm no expert either but I really don't think APN settings would cause the tower to drop connection. AFAIK APN settings are just for data and MMS services.
I understand it's not your video and you knew APN is for data and mms. However, you forgot that in mean time, most VZW devices use CDMA for voice until they introduced HD voice (VoLTE) to have both voice and data work at the same time.
So without correct APN settings, nothing is gonna work including voice for non-cdma devices.

But yes. I am up and running on LTE+ right now. I would post a screen shot... But I don't know how
Can you help me?

I saw your post also on the verizon regarding the XZ working with it. That's cool man! I bought the XZ based on the LTE network which I was betting that it would work but no good. I currently have a z3v working with HD calls and stuff so that's why I believed that XZ would work.
Thank you in advance!
APN configuration
Hi! I found out this configuration on a Google search claiming that XZ works with verizon.
Just Google for
1587_13_verizon_apn_settings_for_sony_xperia_xz
On "apn gishan net" and you will find out. I will try it as soon as I arrive on my vacation destination (currently driving)... Lol
Not that simple...

Well I did the setup but I wasn't able to get it work. @MpV35;73223832 can you please share the info that you got on the tier2 verizon help-desk? (I saw your comments on the verizon community)
Thank you one more time

Att wifi calling

I was able to setup wifi calling on att, but is set to mobile preferred, anyway to change this? At least on phone app settings I cannot change it to wifi calling preferred.

I just set mine up, and can't find the option either. I just googled this problem and it appears the same thing happened on the Pixel 2. One guy said that he called Pixel support and they said that it isn't possible to set wifi calling to preferred. Apparently wifi calling will kick in when needed. I tried it just now, and it seems to be working.

Excellent to have Wifi Calling on Att finally on our pixels!:good:
I was wondering if wifi calling would work with at&t. If I remember right hd calling worked with the p2 with the right sim and getting it provisioned on your line but wifi calling didn't work. That only worked on phones from at&t. There were a couple places that I needed wifi calling and it came in handy. One was in a couple places at work with bad cell service and another was in a friend's home in the mountains of PA. wifi but no cell towers around. If wifi calling works at all I'll be glad.

So nothing happens when you tap Wi-Fi calling then. Bummer
Edit: we'll have to wait for custom ROMs

Yeah I'm surprised also. I always missed wifi calling on my Pixel 2 XL. I definitely works on my Pixel 3 xl on AT&T, you just can't set wifi calling to preferred.

Wifi calling does work, I tried a test call and it worked fine. I'm glad, because I live in an area where the cell signal is very weak.

That's great that it works. I would only need it when cell is unavailable. I sold my p2xl and had an s9+ for a while. That was a mistake. It was a good phone but I need my pixel back. Thanks for the info.
If I remember right that's how all the pixels are even on Verizon.
No option to make WiFi calling preferred.
At least it is working on Att because previous ones did not.
On my Pixel 2 XL, on TMobile, I have the option to set wifi calling to preferred. My 3 had not arrived to check yet. I do not have the setting in your screenshot for the emergency address.

What service do you have?
I know on Verizon you could never make it preferred, and Att never worked.
Unless Verizon changed after I changed carriers

This is what we see on AT&T...we don't have the option to select calling preference.
Guys!! This is a huge win for pixels and non at&t branded phone lovers!!! Never before in the history of at&t and Android has VoWiFi worked on non at&t branded phones.. I couldn't believe my stroke of good luck when I tested it today!! Thank you thank you Google. I had switched to TMobile because of this and carried at&t as secondary to fill in the gaps.. but i may just switch back.. so happy.. also, TMobile is the only American carrier that let's you prefer wifi calling over mobile.. so no dice there.. but hey, I'll take it.. and you can always enable airplane mode and force wifi calling.
Also, I tested tonight in a poor at&t coverage area and it seemed to switch between wifi and cellular calling just fine!!

If it does for you that's great...I tried it for 24 hrs. Had no signal my whole day while work in my office. So no go for me, even with it being a lot cheaper service.
I do hope they keep improving though, for competition purposes.

Yes they do! In so many ways and areas. And they have improved so much in the last year. I travel a lot and love watching coverage and I could name dozens and dozens of new towers. But they need 100s and 100s to compete.. let's hope the Sprint/tmo merger got through. It would be awesome to have reliable competition to dumb and dumber.
