This app is intended for dual SIM Samsung Huawei and ZTE phones: it won't (probably) work on different brands and will be useless on single SIM phones.

The two features of the app are:
- schedule an alarm that reminds you to enable or disable work SIM at shceduled times (for example at 9am when you go to work and at 6pm when you go home)
- a widget lets you open Dual SIM settings directly from the home screen

Officially supported phones:
- Huawei P9 (and probably all other Huawei phones)
- Samsung S4 mini duos (and probably all other Samsung phones)
- ZTE Blade S6 (and probably all other ZTE and Nubia phones)

This app is open source you can can find the code on our GitHub repo: https://github.com/mobimentum/dualsimreminder/

We're accepting feature requests to extend the functionality of the app just file a new issue here: https://github.com/mobimentum/dualsimreminder/issues
