Hi there! I'm planning to use multiple sim cards for the transmission of my data and instead of using multiple modules, i think of using sim hot swap technique. Has anyone here tried using the method? What I plan to do is to use multiple sim card connectors and use a multiplexer to select which of the holders will connect to the GSM Module and will be used for transmission. I think its possible but I need some documents to prove that it really is possible, to convince my professor. Can anyone send me links to projects who had done it? Any other better ideas will surely help. Thanks a lot!
