Can we program an application which will enable toggling the numbers of a sim card with 2 numbers?
Does Android provide any set of api's in its documentation?
If so kindly help to know
If not what would you think is the best way forward
I knew of developer friend who tried to use special SIMs and was able to use the SIM toolkit functionality to switch IMSIs. 
Can you help me know about the installation of SIM toolkit in terms of the Android software stack? or a link that can help me get this functionality working?
