Am gasit o metoda simpla prin care se poate activa VoLTE si VoWifi pe OnePlus 7 si 7 Pro pt Orange. Posibil sa mearga si pt Digi, nu am testat deoarece nu am SIM Digi.
Pasii care trebuie urmati se regaseste in linkul de mai jos, dar le enumar si eu.
1. Download the OnePlus Log Kit app’s APK from the link here.
2. Install the OnePlus Log Kit app using its APK file.
3. After installing the Log Kit app, open the dialer app.
4. Dial *#800# to access a secret menu.
5. You will see a warning pop-up. Tap on Enter. (Note- Follow the steps cautiously as a wrong step or move can damage your phone beyond repair.)
6. Tap on the OnePlus Log Kit option on the top.
7. Scroll down and tap the Function switch option.
8. Tap on VoLTE Switch option and then tap on cancel button.
9. Tap on VoWiFi switch option and then tap on the reboot button.
10. Your device will get restarted and when it turns On, you will see that the VoLTE and VoWiFi feature is enabled on your OnePlus 7 Pro.
Once you have followed the above-mentioned steps, then you can enable the feature easily. I would like to again bring to your notice that, please follow the steps carefully and sequentially to avoid any permanent damage to your device. Moreover, once you have enabled this feature, you can access them by;
Tap on WiFi & Internet option.
Select Sim & Network option.
Mentionez ca nu este nevoie de root.
