OnePlus How to enable or disable call barring

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.
