Sim card communication device

Hi, please check [login to view URL] and [login to view URL]

This flexible pcb design has been used to provide dual sim capability to phones.

I assume that it is basically filtering sim card and phone communication and when it is catching #11 or #22 input, it does the switch from sim 1 to sim 2.

I need to filter something else between phone and sim card, I will explain it over chat, if you think that you can do similar pcb and embedded software please contact me. Thanks.
