How to set up WeChat voice on oppo mobile phone without being interrupted by phone?

If a mobile user is engaged in WeChat voice and a phone call suddenly comes in, the phone will interrupt the WeChat voice call, because the phone has the highest priority, and the phone and WeChat are on the same link, which is in conflict. Open the settings, click on the wireless and network to select the mobile network, and open the voLTE HD call button. Wechat voice will never be interrupted again, but a telephone call interface will appear, giving you the right to choose. VoLTE setting method:

ColorOS 7 and above: "Settings > SIM card and traffic management >: Select a SIM card > VoLTE HD call".

ColorOS 3.2-6. 1 Version: "Settings >; Dual card and mobile network > select SIM card > VoLTE call ".

Remarks:

1, OPPO models use telecom cards to turn on the VoLTE switch by default, and mobile phones cannot turn off this switch.

2.OPPO 5G models use Unicom cards. If the 5G switch is turned on, the phone will turn on the VoLTE switch by default. If VoLTE needs to be turned off, the 5G switch must be turned off first.

3. VoLTE switch cannot be set during the call.

4. After 4.VoLTE is turned on and registered successfully, the word "HD" will be displayed in the notification bar of the mobile phone.
