Will telecom carriers block or flag my SIM card for sending SMS?

Carriers flag SIM cards when they detect burst traffic or receive user spam complaints. ApnaSandesh enforces a 3.5s to 6s safety throttle between sequential dispatches and automatic opt-out suppression to keep your SIM in complete compliance.

Why is there no cloud dashboard or web login?

By keeping ApnaSandesh 100% on your Android device in a local Room SQLite database, we eliminate server operating costs, avoid user data leaks, and ensure the app works even with mobile data turned off.
