摘要
This invention represents a communication system for providing mobile communication between a network and an mobile terminal, the mobile terminal being equipped with one or more SIM-cards, the one or more SIM-cards having at least a first and a second identifier, the mobile terminal and/or the network having an activation function for choosing one out of the identifiers as an active identifier, the network having a connecting function for establishing calls to the identifier that is active, wherein, if a call to the first identifier is requested while the second identifier is active, a call to the second identifier is established, wherein a first call forward destination is assigned to the first identifier and a second, separate call forward destination is assigned to the second identifier, wherein if a call to the first identifier is requested while the second identifier is active, such that a call to the second identifier is established, but the second identifier is not answering and/or busy and/or not reachable, a communication with the call forward destination of the first identifier is established by a coordination function of the network.
