A mobile radio apparatus for a motor vehicle has a first mobile radio module and a second mobile radio module. Furthermore, a first antenna and a second antenna are provided for transmitting mobile radio signals. To provide robust voice telephony for the motor vehicle that can be implemented with little circuit complexity, a switching device is connected to the antennas and to a respective signal connection of the mobile radio modules and that is designed to take a switching signal as a basis for changing over between a first switching state, in which the first signal connection is coupled to the first antenna and the second signal connection is coupled to the second antenna, and a second switching state, in which the first signal connection is coupled to the second antenna and the second signal connection is coupled to the first antenna. |
