Wireless device with multiple SIM cards

摘要

The device has a mobile station (103) connected with a mobile radio network (102) under usage of a subscriber identity module (SIM)-card (101a). A multiplexer (106) is connected with the mobile station for accommodating the SIM card, and has a switching unit for connecting the card with the mobile station. An interface e.g. universal serial bus-interface, establishes a data connection to the mobile station. Another switching unit switches-off the mobile station when the card is separated from the mobile station and another SIM card (101b) is connected with the mobile station. An independent claim is also included for a system for checking a service quality in a mobile radio network.
