For example, if we are abroad with the OnePlus smartphone and want to avoid additional costs, a call barring function can be activated which blocks the corresponding outgoing or incoming calls.
The following options are available to us in the phone app
- All outgoing
- Outgoing international (home country excluded)
- Outgoing international roaming
- All incoming
- Incoming international roaming
Note: When using Dual SIM, call barring can be set up individually for each SIM card.
The call barring password must be requested from the relevant network operator.
