DualSim Reminder

Tools for dual SIM devices from Samsung
Intended for dual SIM Samsung phones: it won’t (probably) work on different
brands and will be useless on single SIM phones. The two features of the app
are:

* Set an alarm that reminds you to enable/disable SIM at scheduled times, e.g. for working times.
* Add a homescreen widget that lets you open Dual SIM settings directly.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.

Download F-Droid
  • Version 3.1.00 (3100) suggested Added on 2021-06-24

    This version requires Android 4.2 or newer.

    It is built and signed by F-Droid, and guaranteed to correspond to this source tarball.

    Permissions
    • run at startup
      Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the phone and allow the app to slow down the overall phone by always running.
    • prevent phone from sleeping
      Allows the app to prevent the phone from going to sleep.
    • set an alarm
      Allows the app to set an alarm in an installed alarm clock app. Some alarm clock apps may not implement this feature.
    • have full network access
      Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.
