Dual SIM Switch Widget was the first free app that gave us ability to toggle our SIM cards on and off as well as mobile data using simple widgets on our home screens. Plus schedule. Plus option to skip weekends.


No further development
This project was abandoned on January 18 2015. App stopped working properly on devices powered by Lollipop and I didn't fix it... Originally I made this app for myself. I liked the fact many people used it but I couldn't have committed to it.


Limitations
It was designed for most dual SIM phones based on Mediatek chipsets but not all. If it works on your dual SIM device I'm glad.
