no mobile data when calling - OnePlus 6T Questions & Answers

Hey guys,
when calling someone, my wife for example, it says HD in calling screen. What does it exaclty mean? It cant be VoLTE because there would be a status bar icon which is not there.
I wouldn't care about that but my problem is that I dont have mobile data during a call, at least not on LTE. I dont know how it looks in other networks but could there be a relation to the HD call? Sometimes I really need mobile data during a call, especially when tethering with my laptop. I havent found a solution yet, not in settings and not online.
Any help or suggestions to make it possible?
Thx in advance
Edit: Thats what I found in OP community so I'm obviously not the only one.
This is 100% a bug/ issue. It's not normal behaviour for your phone to lose data connection whilst making a phone call, any decent modern smartphone should be able to handle this multitasking operation, let alone one with a Snapdragon 845!
I have access to three different phones, a Xiaomi redmi 3S, WileyFox swift 2 and my 6T.
ONLY the 6T drops my data connection when making a phone call, I have used the same SIM to test, so it's not the carrier. I'm pretty sure this used to work, as I make quite a lot of conference calls handsfree and often need to use Google whilst on a call.

HD means that you are most probably using VoLTE connection (technically you may have HD call on HSPA as well, aka 3G).
What carrier are you using? Are you using 2 SIM configuration? You will lose a network connection if your data is on SIM1 (T-Mobile for example) and you have second SIM Verizon and enabled Dual LTE in settings.

Thanks for your replies.
I'm on Vodafone Germany.
Single SIM.

If VoLTE is available in your area and through your carrier that allows you to place a phone call over your LTE connection instead of the more common voice networks. So it really depends on the area/location availability where your carrier offering.

I think it's not part of my contract and it never showed up in status bar so I don't know if it's really volte.

You haven't enabled VoLTE on your device. There is a long thread on the forum showing the trick to enable the feature on Vodafone Germany.

Are you using the stock dialer? The feature doesnt work with the Google Phone app ports.

Enable voLTE on Galaxy Note 4?

Hello,
I am currently with T-Mobile and own a Galaxy Note 4 SM-N910U model, the exynos variant. Is there a way to enable voLTE on this device through some menu? My carrier supports this feature and I know my phone does as well, but it is disabled because the data drops to 3g whenever I make a call.
Anyone?
On mine is in the menu

I confirmed with Samsung that the device indeed has support for voLTE if your carrier supports it. They informed me that it should be turned on by default, which is a lie because my carrier has voLTE and whenever I make a call, the data drops to 3g.

In Japan......if we bring a self acquired device and use it on their network.......certain feature will not work.
Like VOLTE....as I just discovered. They have a separate APN for other devices and it does not support VOLTE.
The other APN that their carrier branded phones use....recognizes the phones based off of their IMEI number.
So.....it might not be a phone issue. Could be your carrier skimming on certain features for phones purchased elsewhere.
Don't see it on my sm-n910f either
hi all, i don't see the menu in my SM-N910F
In your opinion, Is it possible that VOLTE works only on Note4 Exynos? and doesn't works on Snapdragon based Note4 ?

Just go to 'Phone' & then tap on 3 vertical dots and then select 'settings' and then select 'call' and after that enable VOLTE
can someone explain me what is the purpose of Volte? for what you use this?

volte is Voice Over LTE. It is basically what it says on the tin. You can make voice calls over LTE internet connections.
VoLTE (HD voice) and Wifi Calling WORKS with the SM-N910T.
I am currently using this device, with "MetroPCS by T-Mobile". As of 01-29-2021, T-Mobile will only allow the SM-N910T to work on their network. The "T" variant only, because it is T-Mobile's own device. VoLTE (HD voice) will work if you use OEM stock Android 6.0.1.
Here's how I enabled VoLTE (HD voice) and Wifi Calling:
Backed up ALL my files.
Removed SIM and SD cards.
Made sure battery had at least 80% !!
(If using a generic battery, it must be 100%. They drain faster!)
Used Odin (v3.13.1) to flash/install lastest Stock Android 6.0.1. (This wiped everything, even storage, pics, etc.) First boot took over 20 mins!
After reboot, connected to WIFI.
Went to phone's Settings, About Device, Software Updates, and tapped Download Updates Manually. This caused it to find a modem (baseband) update. I chose to install it NOW. It did just that, and rebooted.
Powered off phone.
Reinstalled SIM and SD cards.
Turned phone on, and VoLTE (HD voice) was fixed. Whenever I speak with another HD caller, "HD" appears next to their name.
To enable Wifi Calling, go to Settings, More Networks, Wi-Fi Calling, and enable it.
CAUTION / Extra Info:
A few days ago, I broke the screen on my primary SM-N910T. The screen would not light up, and it did not respond to any touches. I went to a MetroPCS store, to move my account to another SM-N910T. The sales rep said he could not move my account to the other device, showed me his computer screen as "proof", and said it needed to be HD voice compatible. I told him both phones are identical, and both had VoLTE working perfectly. Then he offered to try it anyway for $29 (non-refundable). I politely declined, went home, and swapped the motherboards. All is fine again. I shared this story in case you encounter similar resistance, and need to tell the sales rep you are willing to take a (non-refundable) chance. And to warn you that T-Mobile might have made some changes, that I am not aware of. However, I am currently using the SM-N910T.

Can't make calls when on LTE mode

I have n9005 rooted TouchWiz stock on 5.0,
when my phone is on LTE mode i'am unable to make/receive calls.
Kindly help me solve this problem.
Is the phone set to LTE only? If it is, does the carrier support VoLTE?

LTE/4G is a Data-Only network. To make calls over it your carrier needs to support Voice Over LTE, or VoLTE for short. Which is the mobile equivalent of VoIP.\
If your carrier does not support VoLTE, and your device is only allowed to access LTE, you can't make calls. Change to 'LTE/WCDMA (Auto)' (4G/3G) or 'LTE/WCDMA/GSM (Auto)' (4G/3G/2G) mode so the phone can automatically change to a network that supports voice codecs.

Not receiving incoming calls on AIRTEL 4G LTE
Iam facing peculiar problem with the phone. Need help with the problem.
I am using samsung note 3 LTE. When ever some one tries to call me, my mobile is Not reachable or out of coverage area even when my mobile is in my hand , perfectly working with the second sim. outgoing calls are working fine. Again, when I am in call, then if any one tries calling me, then I get call waiting. So incoming call waiting is working for me. But incoming calls are not able to connect. LTE data is working fine though incoming calls are not working. 
Tried the following but no luck. Problem still persists:
1. Reset phone and erase all data
2. Hard reset phone (volume down + poweroff and clear all data in drive)
3. Tried changing SIM to second slot
When I switch the sim back to 3G mode or 2g mode , incoming calls are working perfectly fine . I googled it and found that most people had same issue and was resolved on switching back to 3G or 2g . 
But I need to use 4g . Please tell me a solution.
I had that same issue until I took my note 3 to Rogers and they said that the note 3 doesn't support Lte
Your rom must support VoLTE.
I would unroot and go back to stock firmware, and see if problem still happens,? if it does ,its most likely the sim card.sd card reader slot, (flex cable),my Galaxy s4 had the similar symptoms , but LTE would work with a custom rom, but not if I used stock firmware, replacing sim card reader flex , just google your mak and model and search ebay. mine cost a few pounds for a decent quality part, so dont go rushing to buy the cheapest. No problems since replacing that part, even after resetting phone 3 times to see if it was a fluke. I know its a bit late for a reply, but this actually worked , I am 99% sure it would work for anyone else who has this problem with lte not connecting when 3G, and 2g do connect. If you have tried swapping sim cards, putting sim in another phone,, etc,etc. this part mentioned(sim card/sd card reader) is your culprit. Took me just over 5 hours of testing to find the solution. thanks and fair well android users

For many people having issues with LTE not connecting and diverting to voicemail on android, I am here to offer a solution to your woes. I have a Samsung Galaxy S4, GT-I9505, and recently in in 2018 in July, I had the same problem, phone calls connected on Gsm, Wdcma, BUT when I tried LTe mode, NOTHING, WENT STRAIGHT TO VOICEMAIL.Anyway I tried almost everything mentioned on certain websites and forums, with some luck, Changing LTE mode to GSM worked, and I could receive and hear phone calls. So I investigated further, I tried re flashing stock firmware, factory resetting phone.(nothing worked). I then rooted my phone and flashed a custom rom (do not try this) as it could damage your device if flashed wrongly. Yeah, so I flashed a custom rom, and low and behold problem disappeared, so I used my phone on LTE for 2 days, with no problems, I then decided to go bacjk to stock firmware, ...problem came back, not connecting to LTE mode..........being as patient as I can be, never gave up, and had a spare phone which was dead, just laying in the drawer, ..so ,I took phone apart and thought, it must be where simcard contact make contact with sim card reader contacts ( broken sim card /sd card reader part, and was I wrong, no, it actually was the sim card reader part which coonects with th motherboard, Voila, I am 99% sure if anyone else has this problem with any android that has LTE capabilities, and you know its not the sim card, then try this fix first, MAKING SURE YOU GET SOMEONE YOU KNOW TO HELP YOU , IF YOU ARE UNSURE OF WHERE TO BUY AD HOW TO FIT. hope this has helped,and I know it is a long thread, but hopefully it will be a solution that works for whoever reads and trie this, over and out. yours in sincerity, Tech82, from Surrey, England.

Yes,data works but calls don't
I'm going to suggest a longshot here. It seems that you've gotten some good suggestions so far, so I want to throw this idea out there.
Have you "provisioned" your phone lately & updated the PRL? Meaning, have you told the phone to connect to your cellular carrier, then the carrier then tells your phone what services you are paying for & are supposed to have & what cellular towers you can use? Doing just this usually fixes all sorts of problems.
Go to Settings (the little gear icon), then More (in the Wireless & Networks). Cellular Networks, Carrier Settings. Tap on Update device config. Let it talk to the network. Tap on OK. After that, Update the PRL. Let it do it's thing. Tap on OK.
No reboot is necessary. It should be making calls, receiving calls & data should all be working.
Also, I keep the Preferred network type to global, although my carrier is CDMA & I'm in the US.

Same problem here. Solution for now is to change to 2G network, at least for me. When I try to call with 4G preferred sometimes it work, but when it works they can't hear me and I have to scream. This Pie update have so many bugs it is ridiculous. I can't believe they put such ****ty update to the masses it seems like BETA version. In Oreo when making call phone switches from 4G to 3G instantly now in Pie switches worry slow if it even switch and the signal is so bad that the call drops and that is in places where the signal is perfect
Hi, since last 4 days i am facing same ptoblem cellular SIM in slot 1 not working for incoming and outgoing calls and outgoing sms but internet and sms service (invoming) is working perfect on 4G
When i switch it to 3G/2G it shows no signals
But when i inserted this same sim in slot 2 all things work perfect. same problem occurred even when i inserted other network sim in slot 1 (internet and sms(incoming) worked but unable to do calls) I had factory reset but problem not solved
I am using poco x3 nfc

VOLTE Wifi Calling with Unlocked S10+

Hey there, I've been doing a bit of research but it has been a long while since i have done any flashing of firmware etc. I received my s10+ device today. Model number is SM-G975UZKAXAA. I am a Verizon wireless customer. When I placed this device on my account I noticed I have no access to Voice over LTE, and I also do not have any access to Wifi Calling. My question is the following. I read somewhere a couple of weeks ago that if I wanted something like this I would need to flash the original VZW Firmware which would have all the lovely bloatware etc on the device. Is there any way I can do that? I have seen firmware that has been posted but I dont seem to see anything that specifically is the VZW apps etc which should (hopefully allow VOLTE and Wifi Calling and maybe even HD Calling, if thats a thing)
I would appreciate any info anyone can provide me on this, as the only solution I can see at the moment is to return the device and start over with a VZW specific device.
Cheers~
Likewise but with a T-Mobile firmware for me

Hey guys, just wanted to check in with you (or anyone else who has wifi calling on unlocked Verizon). It is 100% working? It's the only reason I got the carrier version. Should I cancel and order the unlocked?

Yes, it works with my unlocked S10+ on Verizon. It surprised the heck out of me as I too have the unlocked Note9, but no wifi calling.
What about on AT&T? Can anyone say if they can at least get VOLTE? WiFi calling would be the icing on the cake. Thank you

Wifi calling worked on my unlocked S10 out of the box on T-Mobile. I'll try and check on VoLTE later but I get **** reception near work.
Can you explain how you enabled WiFi calling on unlocked version, on Verizon? I can't find a way to do it. What about HD Voice? My real problem is that data does not work while on a call, using my unlocked, on Verizon. Is there a way to get that working?
I have unlocked S10+ on VZW. I get LTE+ which is VoLTE, data works while on a call.

Hey there, I've been doing a bit of research but it has been a long while since i have done any flashing of firmware etc. I received my s10+ device today. Model number is SM-G975UZKAXAA. I am a Verizon wireless customer. When I placed this device on my account I noticed I have no access to Voice over LTE, and I also do not have any access to Wifi Calling. My question is the following. I read somewhere a couple of weeks ago that if I wanted something like this I would need to flash the original VZW Firmware which would have all the lovely bloatware etc on the device. Is there any way I can do that? I have seen firmware that has been posted but I dont seem to see anything that specifically is the VZW apps etc which should (hopefully allow VOLTE and Wifi Calling and maybe even HD Calling, if thats a thing)
I would appreciate any info anyone can provide me on this, as the only solution I can see at the moment is to return the device and start over with a VZW specific device.
Cheers~

I don't think that is right. LTE+ and VoLTE are different things. As well as data while on a call.
VoLTE means your call is being transmitted over LTE. I'm pretty sure you can use data while on a call WITHOUT VoLTE.

How do you test if VoLTE is working? Do you get an Icon for it?
I tested WiFi calling by going into airplane mode, turning Wifi on, and making a call and it worked. But didn't get a special icon for it.
For those basing your decision to buy unlocked/international vs branded, be warned. I can only speak for Att, but I spent about 2 hours arguing with their level 2 tech department and here's what I have learned. If you have a sim that is provisioned on a branded phone and then put the sim into an unlocked/international phone, you will be able to use volte, wi-fi calling, etc., but only until the carrier pings your imei for a periodical check, once that happens, those features disappear. Also, on Android Pie, the Enhanced LTE Services tab under Mobile Data has been removed as it is turned on by default, also confirmed with ATT. The only way to manually check is to toggle wifi calling on and see if it works. Anyway, just trying to help as I have gone to a branded phone for the first time in 6 years because the reception and enhanced features are more important than rooting to me.
I was able to get wifi and volte working on my unlocked s10 by putting sim into verizon phone, letting network recognize it, enabling advanced calling and such on that device and then taking the sim out and putting it back in my new unlocked s10. The option for volte appears in settings-connections-mobile networks.
VoLTE works on tmobile, not that anyone should be surprised. That has been the case for the S8 thru N9. Now... I noticed that Samsung removed the VoLTE toggle from settings.

Correct, no VoLTE setting on my unlocked S10e, but it is on by default it seems

Using what I learned in this thread, I called Verizon and talked to Level2 support. They tried to get everything working and could not - but this was when I had the new SIM installed, provided by Samsung when I got my S10+.
So because others here spoke of their 'other' SIM, I suggested we try that - so I plugged in the SIM from my S8 and asked them to reprovision everything. They did... and....Now everything that didn't work ... WORKS.
So I have an Unlocked S10+ on Verizon that has (among other things):
- Wifi Calling
- Real Time Text
- VoLTE ("HD Voice") (Which means data now works while I'm on a phone call)
- Visual Voicemail
So it seems the Samsung SIM was part of the problem, and they are reporting this to Samsung. The tech support person told me others have reported similar issues and they will get with Samsung to figure out what the issue is.
Hopefully this helps some others as well!
