Android dual sim detection

Question

I have MICROMAX A100 dual SIM android phone, In my app I am accessing SIM serial number, by default I am getting SIM serial number of SIM 1, How can I access the SIM 2 data ?

Answer 1

This functionality is a hardware implementation by manufacturer (Like some phones have internal and external storage). Default android API is not designed to accommodate all manufacturer imposed features. Though manufacturers are free to modify the android they distribute on their devices and implement new features. And usually manufacturers provide additional libraries for developers to exploit those features. So, Contact the manufacturer if they provide additional API for their devices.
