rSap Server for Android

[harlock]

A software for calling with a smartphone/tablet using another phone sim...
Should be useful in many situations like
Calling with tablets without phone feature
Using 2 phones, one old and simple at work and another one at home (I've broke 2 smatrphones at work)
adding 2nd line, like a dualsim..

No chance. The access to the SIM card is buried deep inside the radio/baseband/modem software. This is a several MB closed source binary.
