If a call is being made on the Oppo smartphone, we can use the "Call waiting" function to inform us when another call comes in.
Call waiting is already activated depending on the network operator, but in any case, call waiting can be activated or deactivated in the phone settings.
- Open the Phone-App
- Open the Menu
- Tap on Settings
- Tap on Carrier call Settings
- Tap on Additional settings
- Choose SIM-Card you want
- Enable or Disable Call Waiting
