Do you want to enable 4G voice phone calls on your Oppo? Well, with the VoLTE (Voice over LTE) feature, you can experience better and high-quality OPPO VoLTE calls as long as your mobile carrier and your location support this.

Below is the step to enable Volte and turn off VoLTE on your Oppo.

Some carriers turn on this feature by default. However, still check the methods below.

Method 1: Go to [Settings] > [Dual SIM & Cellular/SIM Card & Mobile Data], select one SIM card and enable [VoLTE Calls]

Method 2: Go to [Settings] > [Dual SIM & Cellular], select one SIM card and enable [VoLTE Calls]

Method 3: Go to [Settings]>[Call]> [Enable the VoLTE voice call function]. HD/ VoLTE icon will appear on the status bar once VoLTE voice call function is enabled

Note: If your device does not support VoLTE, [Enable the VoLTE voice call function]/[VoLTE Calls] option will NOT appear.

Volte not Working on Your Oppo device? Try the following

If you are using Jio SIM, please uninstall Jio4GVoice/ JioCall application, if it is installed on your phone.

Use the VoLTE enabled SIM card in Slot 1 because VoLTE works best in SIM Slot1.

Change the Preferred Network Type to 4G because VoLTE only works with 4G network.

Go to [Settings] > [Dual SIM & Cellular Data/SIM Card & Mobile Data] > [Select SIM] >[Preferred Network Type] > Choose [4G/3G/2G/Auto].

OR

Go to [Settings] > [Dual SIM & Cellular Data/SIM Card & Mobile Data] > [Select SIM] >[Preferred Network Type] > Choose [4G/3G/2G/Auto].
