A method of single frequency channel communication is proposed, for use with a communication system having different communication areas of different area codes, allowing messages or signals to be transmitted between two mobile phones located in the same or different communication areas through transmitting stations without the use of electronic switching systems. A message inputted from a sender mobile phone is denoted with area codes of the sender and receiver, and converted to a signal for being transmitted to a transmitting station where the signal is processed and amplified. For message/signal transmission within a single communication area, such that the sender's and receiver's area codes are identical, the signal received by the transmitting station is directly forwarded to the receiver mobile phone. For message/signal transmission between different communication areas, the received signal is forwarded to another transmitting station in the receiver's area code, and then to the receiver mobile phone.
