Claim:
A method capable of avoiding interruption due to incoming call adapted to a mobile communication device, the mobile communication device comprising a switch and a control circuit, a subscriber identity module (SIM) card being installed on the mobile communication device, a power pin of the SIM card being electrically connected to the control circuit through the switch, the method comprising: setting a non-interruption period; retrieving an incoming call time of an incoming call signal when receiving the incoming call signal; determining whether the incoming call time is within the non-interruption period; controlling by the control circuit of the mobile communication device to switch off the switch automatically so as to stop to supply power to the SIM card if the incoming call time is within the non-interruption period; and controlling by the control circuit of the mobile communication device to switch on the switch automatically so as to normally supply power to the SIM card if the incoming call time is not within the non-interruption period.
