A communication device is provided with a processing unit. The processing unit reads a plurality of elementary files from a single subscriber identity card for each of a plurality of subscriber numbers when power-on, and registers to a network for each of the subscriber numbers according to the read elementary files. Also, the processing unit enables a multi-standby mode of wireless communications in response to successful registration to the network for at least two of the subscriber numbers.
