Introduction to Unwanted Calls


Receiving calls from unknown numbers is a common annoyance that many of us face. These interruptions not only waste our time but also disrupt our peaceful moments. Let’s be honest, who enjoys unwanted calls? We all despise spam and robocalls!

Introducing SIM Blocker


To tackle this issue, we developed an effective SIM Blocker app designed specifically to stop these unwanted calls. This simple yet powerful call blocker application serves a single purpose: to block annoying and unsolicited calls.


With SIM Blocker, you can ensure that spam callers and unknown numbers do not disturb you. Simply add a number to the blacklist, and the app will take care of the rest. You can also easily manage your whitelist and edit your blocked calls list at any time.

Features of SIM Blocker


SIM Blocker is not just a call blocker; it is a comprehensive security app that offers a variety of functions:


  • 📴 Dual SIM Call Blocker: SIM Blocker stands out as one of the best call blocking apps on the Play Store, particularly due to its dual SIM functionality. It is the only dual SIM app available for Android devices. If you own a phone with two SIM cards, you can customize the blocking mode for each SIM card separately. This feature is compatible with almost all smartphones running Android 7.0 and above.


  • 🕘 Tasks Scheduler: One of the most remarkable features of SIM Blocker is its task scheduling capability. You can schedule your blacklist so that calls are blocked during specific times or set up recurring tasks for weekdays. For instance, you can enable call blocking from 09:00 to 14:00 every Monday and Wednesday. The app automatically manages the scheduling for you!


  • 💬 SMS and Notifications: This app allows you to activate automatic SMS responses and notifications. The app runs in the notification bar, and when a call is blocked, you can configure it to automatically send an SMS and notify you of all blocked calls. Additionally, you can manually reject incoming calls with an SMS whenever you choose.

User Experience


SIM Blocker is beautifully designed and user-friendly. The free version includes ads, but you can upgrade to the Pro version from the Play Store to enjoy an ad-free experience and additional features.
