Revealing Private Numbers on Samsung & Android

Learn how to configure your Android device to unmask hidden callers and block spam permanently.

Android Spam Protection vs. Unmasking

Modern Android devices in November 2026—including Samsung Galaxy and Google Pixel phones—come with AI-assisted spam detection. However, when a caller intentionally hides their Caller ID at the carrier level (using 141 or network settings), on-device Android tools cannot identify them; the call simply appears as "Private Number" or "Withheld".

The Solution: Network-Level Routing

Because the privacy flag is applied by the carrier, your Android phone cannot unmask it locally. Instead, you must route the call to a specialized infrastructure. By setting up MaskOff UK, you leverage our secure servers to force the network to reveal the hidden ANI (Automatic Number Identification) data.

Activation on Android

The setup process uses standard MMI codes directly in your Android dialer app. Once activated, simply swipe to decline any incoming private call. Within seconds, MaskOff UK will process the routing and send you a push notification with the caller's actual phone number.
