Abstract

The present invention discloses a method and a relevant apparatus for achieving localized roaming of a mobile terminal. In the present invention, the mobile terminal sends real SIM card information to apply for a virtual SIM card to obtain a corresponding mobile terminal number of a roaming region, and registers user information to activate the virtual SIM card to serve as a calling party or a called party, so as to set up a called communication connection of a real SIM card. The mobile terminal applies for a virtual SIM card from a communication network of a roaming country to obtain a corresponding mobile terminal number of the roaming region through allocation, so that the user does not need to purchase a new SIM card in the roaming region, thereby saving the charges for purchasing the SIM card, ensuring a convenient operation and satisfying the demand of the user.
