A message processing method, applied to a terminal device including a modem, includes: monitoring a running state of the modem, and restarting the modem when it is monitored that the modem crashes; and maintaining a communication connection state, and prohibiting notification of a modem crash message to a user. By maintaining a normal communication state after the modem crashes, it is ensured that the user continues to use the various services of the terminal normally to avoid the interruption of the ongoing business of the user; and the terminal resumes normal operation after the modem is restarted, and the user does not perceive that the modem has ever crashed, thereby maintaining the experience of using the terminal normally all the time.
