Adapter/switch realized in thin thickness so as to allow primarily the lodging and the connection for two or more SIM (Subscriber Identity Module) cards on a huge number of GSM cellular phones. Moreover, thanks to an appropriate switching microchip system, it allows the enabling one or another of the cards alternatively, so that the user, through an easy manoeuvre of phone keys, can have access at any time to all services and lines, at his own will and convenience, bearing in mind the different rates applicable. <IMAGE> |
