In a communication device, a communicator communicates with a communication counterpart using a first communication mode or a second communication mode. When a communication by the communicator with the communication counterpart using the second communication mode is reset due to a first cause, if the communication with the communication counterpart using the second communication mode is acceptable, a communication controller causes the communicator to resume communication with the communication counterpart using the second communication mode, and if the communication with the communication counterpart using the second communication mode is unacceptable, the communication controller causes the communicator to start a communication with the communication counterpart using the first communication mode. When the communication by the communicator with the communication counterpart using the second communication mode is reset due to a second cause, the communication controller causes the communicator to resume communication with the communication counterpart using the second communication mode.
