Abstract
A mobile phone includes a code division multiple access (CDMA) chip and a first user identity module (UIM) card. A network listening method of the mobile phone burns identification information of a second UIM card into the mobile phone, and executes a first network listening method to listen to a communication network, if a first listening frequency equals to a second listening frequency and a first listening channel equals to a second listening channel. The network listening method further executes a second network listening method to listen to the communication network, if the first listening frequency does not equal to the second listening frequency and/or the first listening channel does not equal to the second listening channel.
