In a few words, I want to be able to house multiple sim card in one enclosure and emulate a given sim card in another location, by connecting the two over internet. A few concepts : - Sim bank : An enclosure that contains a number of SIM cards, which can be used by a gsm gateway. - Gsm gateway : An enclosure containing one ore more gsm/3g/4g modems. What I'm looking for in terms of deliverable : - Hardware: everything needed to build the sim card emulator on the ISO/IEC 7816-3 layer + interfacing it via internet to a management system comprised of one or more sim bank - Software: source code of the whole thing. Have a look at the attached image for a better understanding. What I want is on the green side. I don't want what's on the red side. As a first step, let's discuss how you would implement the emulator device. A few reference to help you : [login to view URL] [login to view URL] [login to view URL]
