A couple of things.. did you get the error message before or after opting into the beta? It's called DSDS if and when it's deployed with Android Q release version. (dual sim - dual standby) What do you mean you got an Airtel Sim and got your QR code? Did you first get a physical Airtel sim and then eventually they sent you a code? It's unclear from your OP

Activate DSDS Model Pixel 3

Bro, Just follow the following and you should be able to get two network signals simultaneouly.
Dial *#*#INFO#*#*
Once you get the Testing screen, go into "Phone Information".
There you would have a toggle called "Enable DSDS".
Once you toggle it, it will ask you to restart the phone.
After the restart, you would have the DSDS functional, with two networks simultaneously.
Then you can go into the "Mobile Network" option and see both networks.
Also, if you now enter the "Network and SettingS" option, you will also see a new option "Sim Cards" where you can choose which sim to use for Data, call, messages, etc.
Try out and let us know how it went.
Please note that you need to be on Android Q Beta2 or more to be able to have the DSDS option.
Just opting in to Beta won't necessarily help.
You would also need to download and install the Beta.
Cheers!

OnePlus 7 and VoLTE/Wifi-Calling

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?

WiFi calling works without issue

what do u mean switch
u just actived it under settings/network/simcard provider
then u can set it to use volte or vowifi
as standart

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

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.

The options are there, but is not possible to activate.

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.

These are the bands supported by the oneplus nord according to gsmarena.com
5G bands 1, 3, 7, 28, 78 - Europe
78 - India
Make sure your carrier is using one of these bands. Some regions use different bands, and a phone made for a region might not work well in another.
Also, are you using dual sim? Because if you are, for Europe atleast when in dual sim mode 5G is disabled until a future firmware update patches things up.

Yes I don't see 5g. I have mobile plan with 5g but I don't we 5g. My provider eses N1 network at the moment. I don't understand why.
OnePlus 8t has the same problem.

OnePlus like other phones have enabled 5G only certain networks. I have list in my blog and also instruction how you can modify your phone modem and enable 5G-support: https://mt-tech.fi/en/modify-oneplus-7-pro-5g-8-and-8-pro-nr-lte-a-band-combos/

As per the excellent guide from @olkitu above, I managed to get my OnePlus Nord to connect to 5G on Telstra (Australia) with pre-paid plan.
Additionally, I was able to get VoLTE and VoWiFi working reliably using this YT guide:
Edit: I'm on OxygenOS 10.5.9 (Android 10)

One question. Do I have to do it each and every time after every Software Update or it is permanent?

Q: Shift/force 5 II to 5G Mode

Hi,
is there a method in which I can shift or force the Xperia 5 II into the 5G mode, since it is alwaxs in 4G although there is 5G within my network (o2 de) available (on phones of my peers and also stated on the network map)?
Best way would be by settings or so without any flash or a file.
Thanks

It's not probably going there for some reason.
You can check Netmonster app https://play.google.com/store/apps/details?id=cz.mroczis.netmonster&hl=en&gl=US
It shows which bands are you currently receiving and it shows presence of 5G NSA.
As far I know, this phone doesn't work in 5G SA mode (at least yet, but I don't think it will happen due all that whitelists that operators have). Because of that you can be in 5G coverage area, but still you won't be able to connect 5G network. Also even if 5G NSA is working, you can't actually force 5G only mode as 5G NSA can't work without LTE network. 5G is also undesirable option as all phone calls are likely using VoLTE, because VoNR is likely not happening with this phone.
In reality it's actually better having 5G off, because battery life is better without it and 5G NSA is only a bit better (mainly for upload, downloads can be actually worse, if your operator uses 5G NSA DSS). Really - 5G is currently mainly marketing scam*, no real benefits from it yet (Unless you want to show off with 5G icon in front of your friends .
*This is actual example of 5G NSA scam by operator. 5G icon is shown, but does it use 5G in reality? No - it's running in 5G NSA mode and see "Odpojeno" with ! in tringle which means that 5G is not used and operator simply block access to it in this area now (And because they uses 5G NSA DSS, I'm not even mad). But yeah, 5G icon is there, so let's show off .

*#*#4636#*#* will give you "Testing' Menu with 'Phone Information' where you can select 'Preferred Network Type'. But don't fiddle with other settings there. Also if 5G is not actually available I don't think selection of preferred mode will have any effect.
I believe NR (New Radio) only will enable 5G where NR/LTE will give you both 5G/LTE.

NR/LTE is set but still not 5G connection... no clue why
