Common dial-up numbers and/or common ID numbers are set for the simultaneous transmission of information, such as news or advertising, to a plurality of mobile wireless terminals. In addition, these common dial-up numbers and/or common ID numbers are also recorded in a switching center that sends out information. When information is sent from the information providers, the switching center simultaneously transmits this information to mobile wireless terminals having these common dial-up numbers and/or common ID numbers.
