Question No Volte & VOWIFI option ??? - OnePlus Nord 2 5G

Hello. On my oneplus nord 2 DN2103, software version DN2103_11_A.17 I don't have the Volte and VOWifi options. I receive 5G without any problem. When I put my SIM card in a oneplus 9 I have the Volte & VOWIFI options. What's the problem ? If I'm not mistaken, the Oneplus Nord 2 does have the Volte & VoWifi option, doesn't it? Any solution ? Thanks

No solution. I own the same phone and have the same issue here in the USA. After google searching, it seems to be a frequent topic of discussion on the OnePlus community forum. Looks like OnePlus has only opened up the feature to certain carriers. There's no way to activate it using dialer codes or anything else.

Strange , same version DN2103_11_A.17 , base band M_V3_P10.M_V3_P10 , DIGI Romania , Volte & VOWiFi are present .

In Poland on Play mobile present in sim card settings.

Depends on carrier yes, same issue here in France, with Free mobile.
I've asked carrier's tech support, no answer yet.

Open the Phone app, dial *#800# , and select EngineeringMode. Once you're inside OnePlusLogKit, scroll down a bit and check the “VoLTE switch” and “VoWifi switch” options. You may also need to check “VT switch” for some carriers.

You must not have a Nord 2 because this doesn't work. That just brings up a feedback menu that allows you to submit feedback to OnePlus. There's no Engineering mode, or OnePlusLogKit whatsoever.

Adb in recovery mode doesn't work since A14 or A15 update.

so whats the "solution"?? Im on A17 (DN2103)
how we can enable it? maybe via a custom rom?

---

I think you Can enable it with root as you don't need to adb in recovery mode and use in phone terminal, Idk for custom rom.

HI. I don't understand, I check SIM1 and VoLTE is enabled and wi-fi is on.
Is your problem with operator/SIM?

---

There is no option for volte and vowifi or 5G
In my OP3T with custom rom volte and vowifi options was available.
Sometimes when i make a call an HD logo (no volte) appears on call timer.

---

Yes it's a sim/carrier issue, I have same issue.

With a rooted phone and magisk:
1. install magisk hide props
2. Add the following custom entries:
persist.dbg.ims_volte_enable
persist.dbg.volte_avail_ovr
persist.dbg.vt_avail_ovr
persist.radio.VT_ENABLE
3. Reboot
I'm on 2103_11_A.02 with AT&T and it's working

1. Once you install hide props, enter the menu with command "props" as root
2. Then press 5 for custom entries
3. Then n for new and add the commands one by one
4. When prompted for values use a "1" for all values

Ok that helps.. but after reboot device no volte icon on statusbar either options on settings sim card about volte.
My carrier supports volte but not official for my Nord2.
Same sim on other "certified devices" appears volte+vowifi options.

---

Instructions entered with Termux under Root. Now I can configure Volte and Vowifi in the menu but the problem comes from my operator Free (French operator). I even notice that if the Volte option is validated when my friends call me, they notice that the line is busy. If I remove the Volte option everything becomes ok again. French operator "Free" says that the Volte option is supported for the Oneplus Nord but not for the Nord 2 for now.....

---

What do you mean you can configure the volte and vowifi in menu? How? Where?
Why i can't see that too?

---

After typing the instructions under Termux given by Big_lou the possibility of configuring Volte and Vowifi appears in the Sim card menu as you can see on this screenshot. But since my provider doesn't allow the Oneplus Nord 2 to use the Volte function, it doesn't work...
