OnePlus 7 and VoLTE/Wifi-Calling - OnePlus 7 Questions & Answers

You got any issue with VoLTE or Wifi-Calling?

I had this problem. Oddly what solved it was removing the sim and factory reseting then putting the sim back in. Volte finally worked after that. Seems like a bug in OxygenOS

No Wifi-Calling?

You guys have stable Wifi-Calling connection?

Yes. I've had no issues with T-Mobile WiFi calling. Works fine.

@LandLockedPH T-Mobile US??

Quick update...
I went ahead and pulled the trigger on the OP7 (non-Pro).
I'm using a T-Mobile SIM (Sim 1) and AT&T SIM (Sim 2).
I can confirm that I"m getting VOLTE on both SIM's and VOWiFi on the T-Mobile SIM.
Really happy with the device!

I know not band 71 but how about 66?

Vowifi doesn't work on vzw

Does firmware for gm1905 exist? I'm thinking this also opens bands 66 and 71.

I don't think however carrier aggregation works with the op7 and TMobile USA.
I ran a few ookla speed tests compared to my s10+ using mobile data only. Long story short the S10 would average download at approx 90mbps and the OP7 around 35mpbs.
The only way I could get the S10+ to attain similar figures to the OP7 was for me to disable LTE bands 2, 12 and 66 . In essence making it just use just band 4. Then the download speeds were similar.
On side a side note, having wifi calling enabled slowed the tests results further as you can see by the lower earlier results. Attached screen shot.

It would have been nice if there was a clear indicator that one was making a wifi calling is ready. Due to the notch I have disabled a few status bar icons including viofa and Volte. When placing a wifi call I have swipe down to check it it's wifi calling or not lolz

Calling Problem (Airtel 4G)

(On LTE). Doesn't work on 3G as well. On 2G, it's fine. But I'm not satisfied.
Current ROM- CM13.0 Unofficial by sultanxda.
But this problem has been there on every ROM I've tried. This problem was not there when I was using a 3G SIM. I've tried switching 4G SIMs but the problem persists. Please help! I want to use LTE and make calls together without changing the settings each time. The signals remain there the rest of the time but it gets disconnected as soon as I make a call. FUN FACT- SMSs work fine. Note- This isn't a ROM problem. I've called the technical support but they just don't know how to handle ****. This is very disappointing.
I'm using an Airtel SIM (India)
Thanks!

Where in India? I use Airtel 4G and never experienced this issue.

In Faridabad (NCR). I just don't know what's wrong. I've tried almost everything.

Airtel doesn't support voice over LTE. But your network should be automatically switching to 2g when a call is made and then back to 4g after the call. There will be no data access during the call except for WiFi.

What about that dialog box in the screenshot?

Try going to a place with a good signal and doing a network scan and select airtel manually instead of automatic.
There's a tower right next to my place, so I always have full connectivity. And I've already tried selecting Airtel. The problem still persists.

If you know how to flash custom baseband/modems, maybe you can see if a different one can fix the problem.
If that doesn't work, then a factory reset is the last resort.
Nope, tried that as well. I perform factory reset every now and then.

Well, I forgot to mention that the issue got resolved automatically after a few days. I don't know what actually fixed it. Maybe jgcaap's ROM, or a complete wipe. But it was fixed. Weird issue.

Anyone managed to get VoLTE working on EE S6? Whats needs to get volte working?

Has anyone managed to get VoLTE working on EE UK network on the S6? The current and very old EE firmware doesnt have it enabled.
I believe you need to have the options for VoLTE enabled in the config file and also have the EE EVR CSC code for Volte to work, is that correct?
You also have to rely on EE to actually get it working. It's been up and down for a few weeks now.
The official word is so long as you bought your phone from an EE shop it'll work when they activate it. However, I have had it working fine on an EE 920F(EVR) with a BTU rom, and I know of another member who has had it working on a BTU bought from cpw.
Marshmallow (6.0.1) is definitely needed. Once it's solidly active I'll make my working csc files available for download.
Excellent thanks. I believe you need an new APN as well to get VoLTE? I read about S7 people having a new one called IMS. Do you have th APN settings for this IMS APN?
Thanks.
I have the settings for the new apn too

Turns out I don't have true VoLTE. It's working more like Wifi Calling over LTE. Has the same result, as in it stays on 4G/LTE for any call I make (essentially the same job).
If you want the details I can post them for you, but bear in mind I'm running a custom ROM that makes my phone think it's a G925F (edge).

haha nice! wifi calling over your own 4G, nice
yeah send over the settings, althogh i think im going to give up for now, im due an upgrade in a few months now anyway
Don't forget to backup your current csc files first - just in case. VoLTE toggle should appear in settings>Mobile networks. Need to reboot. May take a while for it to become active on the network - you'll see the wifi calling icon in the statusbar when you're connected to 4G.
Good luck.

Turns out it is VoLTE. EE are implementing it in a weird way, but it is working properly.
Thanks buddy
EE aren't implementing it weirdly. 4G has no voice component so is a data stream over internet traffic.

Thanx. It really does seem weird to me. I was expecting volte to have it's own icon in the statusbar for a start, but all I get is the wifi calling icon. Calls definitely go over LTE when wifi is disabled.
I'm getting on in years but retain enough brain cells to see what's happening but not enough to fully understand it all. I do my best lol

Huawei P20 disable 2G?

Hello i want to aks is there a possibility to disable 2g and leave 3g/4g only? I enabled option to see many types of networks, but when i switch to lte/wcdma only he resset to lte/wcdma/gsm... Many other types doesent work except 3g only and lte only. Anyone maybe fogureout why is that so?
Don't do it. Afaik it's like this: If a phone is capable to use 4G/LTE it will always use 4G till it's not available anymore. Then it will switch to 3G and if 3G get's lost too it will use 2G then. So 2G is only in use when the other "G's" are not available. When you disable this network and 3G and 4G are unavailable you'll have no data at all. Or did I misunderstood your question?
Yes, but i always have 3g. But sometime he bug and stay on 2g so i need to use airplane mod on and off and he ****ch to 3 or 4 g from 2g. Thats why i want to have a option to disable 2g

You can choose 3G only in the network settings, 4G only doesn't exist.
It exist if u enable it. 3g/4g exist too but when i enable it he resset to default

Thank you very much. But the link should already have been in your first post! The screenshot alone isn't very helpful without the instructions to activate this very special menu.
Same problem and that's not helpful. 2G is very not security for now. I want choose no signal rather than 2G

The issue is not relevant since 2017.
According to the media news and Wikipedia 2G has been superseded by newer technologies such as 2.5G, 2.75G, 3G, 4G and 5G; however, 2G networks are still used in most parts of the world. Various carriers have made announcements that 2G technology in the United States is in the process of being shut down so that carriers can reclaim those radio bands and re-purpose them for newer technologies (e.g. 4G LTE).
Honestly for two years I haven't seen 2G on my device even when traveling. The rest of the countries who still might be using it will shut it down soon.

volte

hi,
is it possible to enable volte and vowifi on rmx2071? and how?
If you mean enable as the option isn't there, then sorry I can't help.
But if you mean enable, as in switch it on, then mine is under settings/sim card & mobile data/(select your sim card) /and its under network settings... 'WiFi calling'.
Unless of course the Chinese rom doesn't have it......
No way

I have the same issue with RMX2071. No VoLte, wifi calling or video call. whenever I place a call, the network changes to H+. Hopefully it works once we are able to flash a Global rom.
i have flashed a eu rom rmx 2076 but no volte options

I have the same issue but in my case is for two reason:
1. My provider not enable VOLTE in the sim. I test a Google Fi Sim and enable the VOLTE options in Settings.
2. Some provider have a internal IMEI list to enable the VOLTE service. If your device IMEI is not provisioned in this list even enable VOLTE options on the X50 Pro can work the service.

It looks like VoLte and HD call functionality has been a blame game between service providers and handset manufacturers. I am using Lycamobile in the US. The same sim card works flawlessly with VoLte and video calls when I put it in Lenovo Zuk Edge that I bought in early 2017. But this handset RMX2071 doesnot work.
does volte work on the global rom ... at least in the US
With RMX2075 VoLTE also not work.

I have RMX2071. After I upgraded to Android 11, some calls are shown as HD calls in the calls history. I wonder if they enabled VoLTE globally on Andoid 11. I have Chinese stock ROM.

5G

No 5G option on my preferred network.
Do you have A40 firmware yet? If not, then that's probably the reason why. On android-hilfe.de there have been a lot of people with 5G issues but they have been resolved with the new firmware.

Nope. I have the Vodafone model and I have 5G options within my settings

I've flashed latest german firmware .A42 and still don't have the 5G option...
Do I need to install firmware from another country?
Could you guys trigger "Developer Options" and check if "5G Network Mode" is greyed out or not
They activiated mine when I downloaded Android 11.
Do you guys have the CPH2025 model with 5G logo on the box? Then you should perform a factory reset, to see if that's help.

Also mine activated on Android 11 BUT,
I did 5G Speedtests many times and compare it with NOTE 20 Ultra .
Find x2 pro : 20 to 40 Mbps
Note 20 Ultra : 160 to 280 Mbps
The same time, area and SIM card .
Also 4G is Faster than 5G and I don't know why .
When I got my phone via O2 in the UK, they told me that I would need a new SIM card because of 5G. I've not bothered to look into why this was necessary, but perhaps you need a new (5G compatible) SIM card too?

@HamdiPiixel I had the same issue. Open the telephone dials and enter *#54794824# Do not hit the dial button though. After youve entered the code a message in the lower half of the screen should appear saying "5G switch activated". Then the option should be there. If not check if it is there after a restart.
Thanks you bro it's work you save me
