The invention provides a communication parameter recovery method and a communication parameter recovery apparatus. The communication parameter recovery method comprises the steps of in the startup running process of a terminal, detecting whether an NV parameter of the terminal is corrupted and/or lost; when it is not detected that the NV parameter is corrupted and/or lost, keeping continuous running of the terminal; and when it is detected that the NV parameter is corrupted and/or lost, rewriting a default communication parameter in a Modem processor into a corresponding NV item according to a preset recovery mechanism in the Modem processor of the terminal to execute communication parameter recovery operation. Through the technical scheme provided by the invention, the communication parameter can be quickly, effectively and automatically recovered when the communication parameter of the terminal is lost and/or corrupted, so that a communication function of the terminal can be recovered, the data security of the terminal can be effectively protected, and the user experience can be improved.
