SMS Limit Override (ADB)
المتطلبات المسبقة
- A computer with ADB installed
- USB cable for your Android phone
- USB Debugging enabled on the phone
The Android SMS Limit
Android has a built-in limit that restricts apps to sending approximately 30 SMS messages within a 30-minute window. After hitting this limit, subsequent SMS sends are blocked for the remainder of the window. This is a security feature to prevent malware from sending premium SMS messages.
Why Override Is Needed
For SMS campaigns or high-volume business messaging, the 30-message limit is too restrictive. SIMtrix provides an ADB (Android Debug Bridge) command that raises or removes this limit, allowing your phone to send more messages per time window.
How to Apply the Override
This is a one-time setup: (1) Install ADB on your computer (download from Android developer website or install via package manager). (2) Connect your Android phone to the computer via USB cable. (3) Enable USB Debugging on the phone (Settings > Developer options > USB Debugging). (4) Open a terminal/command prompt and run: adb shell settings put global sms_outgoing_check_max_count 10000. (5) Disconnect the phone. The setting persists across reboots.
Safety Note
This override only affects the sending limit, not the SIM card capability or carrier limits. Your carrier may still enforce their own SMS rate limits. The SIMtrix campaign scheduler already spaces messages at safe intervals (minimum 35 seconds) to respect carrier limits.
