发明名称 METHOD AND DEVICE FOR CONTROLLING TELEPHONE CALLS IN A PLURALITY OF MOBILE RADIO NETWORKS
摘要 A mobile radio (1) has a housing (2) with a recess (15) which is associated with the housing rear face (11) for a specific SIM card (12). Furthermore, however, this rear face has further associated recesses (18) in which further SIM cards (12, 12', 12'', 12''', 12'''') can be inserted in order in this way to provide the user with the capability to dial into specific radio networks, which allow network-internal calls, by activating or addressing the appropriate SIM cards (12). IC charges and the like are thus no longer incurred, with further operational reliability advantages also being provided.
