Secure Call Zain is an Android app developed by Zain SA. This free utility and tools app provides users with a solution to manage their phone calls effectively. With Secure Call Zain, subscribers can take control of their received calls by implementing a pin code requirement for callers to reach them.

The app offers various screening modes that users can enable or disable according to their preferences. One such mode is the greylist, which prompts callers to enter a specific pin code before being able to connect with the user. Alternatively, users can create a whitelist to allow selected contacts to bypass the pin code entry. Additionally, the app allows users to create a blacklist to block incoming calls altogether.

What sets Secure Call Zain apart is its customization options. Users can set screening rules based on specific time periods, such as day and time, and group them by single numbers, groups of numbers, or even countries. This level of customization ensures that users have full control over who can reach them and when.

Secure Call Zain is a reliable solution for managing phone calls, giving users the peace of mind and control they need in today's connected world.
