When a call is made with the other party, a "call" is displayed on the display unit 32 and, according to the charging signal, the coin accumulator 26 stores the coin equal to the call rate set in the basic unit rate / time setting unit 32. On the other hand, the card reader unit 28 deletes the amount of information corresponding to the set call rate from the inserted card information amount (step 14), and determines whether the handset 21 is on-hook after executing the step 14 (step 5). If the call is not in progress, it is determined whether the basic unit call time has elapsed (step 16). If the basic unit call time has elapsed, it is determined whether the amount of coins or card information inserted is equal to or less than the unit call rate (step 17). After If it is more than the above charge, after charging the set rate in the basic unit rate / time setting unit 33 set in proportion to the talk time and distance (step 18), the step 15 is executed, and if it is less than the unit call rate, the coin accumulation unit ( The balance accumulated in 26) is returned or the inserted card is returned, the display unit 32 is cleared, and the wireless unit 30 is controlled to transmit a call termination signal to the cell site. When the card is used, the voice service unit 24 outputs the data "Receive the card" and then outputs the data "thank you" to the receiver or speaker Spk (step 24). If "0" is entered twice during the initial phone number input after execution, the voice service unit 24 outputs the data "Cannot make an international call" and then outputs the data "Press the redial button and start again". Then, voice is sent to the receiver side or the speaker Spk (step 21), and it is judged whether or not the redial button is driven (step 22). If the redial button drive is not detected, if the drive is detected, step 7 is performed. If the redial button drive is not detected, the handset 21 detects whether the handset 21 is on-hook (step 23). If it is on-hook, step 24 is executed. If it is not on-hook, step 21 is executed. If after performing Step 11 above, the relaying of the Cell Site relay is congested and the relay cannot be performed. After the message " press the redial button and start again " is sent to the receiver or speaker (Spk), it is determined whether the redial button is driven (step 19). If the redial button is detected after the execution of the step 19, the step 7 is executed. If the redial button is not driven, it is determined whether the handset 210 is on-hook (step 20.) If the handset 21 is on-hook after the step 20 is executed, step 24 If not, execute step 19.
