Abstract
A method for automatically choosing a communication network is applicable to a mobile device. When receiving a communication request for a contact from a user interface, a processing unit determines a status of a network card module according to the communication request. When the network card module is enabled, the network card module sends a network packet and receives a corresponding response packet to determine whether the network card module is connected to the Internet. When the network card module is connected to the Internet, the network card module sends an inquiry packet to a voice over internet protocol (VoIP) proxy server and receives a corresponding response packet to determine whether the contact is online. When the contact is online, the network card module carries out the communication request through the VoIP proxy server. Otherwise, the communication request is carried out by a cellular phone module.
