Buy an SMS package from your cellular operator and send out SMS reminders via your Android phone for free!
The application can be downloaded and installed from our website: Download SmsTransmitter or collect it yourself from the sources.
In March 2019, according to a change in Google's policy, the application was removed from Google Play (located at https://play.google.com/store/apps/details?id=info.ininfo.smstransmitter), as were all applications that could send an SMS in the background.
How does it work
Depending on the manufacturer of your phone and the version of Android, you may need to make additional settings in your phone's power-saving settings for the correct operation of the program in automatic mode.
Cause - In order to increase your phone's battery life, the operating system can close all active applications, even those that are in sleep mode. This is a departure from the standards, but the trick is to increase the phone's uptime.
For example, for Huawei phones, you need to add the "SMS Transmitter" application to the list of protected ones in [Settings] -> [Advanced settings] -> [Battery manager]. Other manufacturers also have similar parameters - Samsung, Xiaomi, lg, etc.
These settings also include "Permanent data transfer in the mobile network", "Support for WiFi connection in sleep mode". When the connection is restored, the application can restore its work in the automatic mode. If the phone is on charging, SMS Transmitter works more reliably in automatic mode.
Open source application, which is a guarantee of safety and transparency. You can also implement your own server and use the application to send your sms, or pick up the sms from the e-call site server and send them in your own way (applicable if you have your own sms gateway with your registered sender name).
