Abstract: A network registration method is described. The method including: reading a RPLMN recorded by a mobile device, when the mobile device is powered on, and obtaining a PLMN of a current candidate cell through network scanning; determining whether the mobile device is initially powered on in a roaming location, according to the RPLMN recorded by the mobile device and the PLMN of the current candidate cell; carrying out a network registration using the PLMN of the current candidate cell, when it is determined that the mobile device is initially powered on in the roaming location. A mobile device is also disclosed. The methods and devices described can simplify network registration when the mobile device is in the roaming location when the mobile device is initially powered. Thus, the network registration can be achieved more quickly.
