How to Enable Full SMS Sending Access for SMS Mobile API (Active and Background Modes)
To guarantee uninterrupted SMS delivery through SMS Mobile API, your Android device must be properly configured to allow the app to operate both in active mode and in the background. This guide explains the necessary settings to grant full access, ensuring that messages can be sent continuously—even when the app is not open. By allowing background operation and disabling battery optimization for the app, you'll ensure that SMS Mobile API remains active and reliable at all times.Step 1: Open SMS Mobile API Settings
On your Android device, **press and hold the SMS Mobile API app icon** for a few seconds until a menu appears above it. Then, **tap the “i” icon** in the top-right corner of the popup. This will take you directly to the system settings page for **SMS Mobile API**, where you can adjust permissions, battery usage, and background behavior.
Now go to your phone’s settings to verify that the configuration shown on screen matches your current setup.
This configuration is personally used and recommended by our technical support team to ensure that SMS messages are sent reliably—even when the SMS Mobile API app is running in the background.
