- Tap on the three-dot menu icon (⋮) at the top right corner.
- Select "Settings" from the dropdown menu.
- Tap on "Blocked numbers".
- Tap on the "+" icon at the bottom right corner to add a new number.
- Enter the number you want to block and tap "OK".
Once you've added the number, it will be blocked immediately. The blocked number won't be able to call or message you, and their calls will go directly to voicemail.
