At a second step, as a receiving user manipulates a keypad of a receiving mobile phone, the receiving mobile phone enters reception mode. Thereafter, the transmitting and receiving mobile phones are operated in data exchange mode for transmitting data from the transmitting mobile phone to the receiving mobile phone. Finally, data transmission from the transmitting mobile phone to the receiving mobile phone is completed.
