Filter unwanted calls from specific contacts, unknown numbers, or based on personal preferences. This service allows you to set blocking rules for different times, situations, and contact groups, so you never have to worry about unwanted interruptions.

Our priority call feature ensures that calls from emergency contacts get through, even if blocking is enabled. This allows family and other urgent contacts to reach you whenever necessary, giving you peace of mind.

When a call is blocked, Who_U automatically sends a customized SMS to inform the caller that you’re unavailable. This service can be personalized with various message templates to suit different scenarios, including requests for callers to share their information.

Set schedules to automatically manage calls based on your daily routines. Define specific times for when calls are allowed or blocked, letting you focus on work, family, or personal time without interruptions.

Our repeat call detection service identifies callers who attempt to reach you multiple times within a short period. If they call again within 3 to 5 minutes, an alternative SMS response can be sent, allowing you to handle potential urgent situations with ease.

Activate Do Not Disturb (DND) mode to silence all calls except for emergency contacts or priority groups. Perfect for important meetings, focused work sessions, or uninterrupted rest time, DND mode ensures only essential calls come through while all others are blocked or muted based on your settings.
