PURPOSE: To attain the calls in a mobile communication system where plural numbers are set according to the calling distances by performing the second call by another set number if the first call fails by a number that is set according to its calling distance. CONSTITUTION: An automatic calling device 1 is used in a mobile communication system where plural numbers are set according to the calling distances when the calls are carried out via a mobile network 5. When the automatic calling is required, the device 1 first tries to call a fixed network 3 by a stored call number 11. If the number 11 shows a portable telephone 7 used in a car, the network 3 is connected to the network 5. If the call fails, the device 1 tries a call again after correcting the first call number 030 into 040 and vice versa. When the call succeeds, the call number 11 starting at the successful number 030 or 040 is stored. |
