In a method for permitting change of an electronic card without powering off and a communications device employing the method, the communications device includes a control module, a card connector for receiving the electronic card, and a trigger module. The method includes: when the communications device is in an on state, triggering the trigger module to generate a trigger signal to the control module; enabling the control module to determine a card insertion mode if it is detected that a state of electrical connection of the card connector with an electronic card changes from a disconnected state to a connected state after receipt of the trigger signal; and enabling the control module for supplying power to the electronic card inserted into the card connector upon determining the card insertion mode.
