[0002] Whether it is mobile or China Unicom users, it is inevitable to go on business trips, business trips, visit relatives or foreigners roaming in China, especially in the 2008 "Olympic Games", there will be more people coming to China, so there will be high long-distance or roaming charges in the user's phone bill ; In addition, during the Spring Festival every year, a large number of migrant workers or students returning to their hometowns lead to a surge in local traffic, but usually the calls are with local users, which will generate high long-distance or roaming charges for users

[0003] At present, "single / dual-mode, dual-card / dual-standby" mobile phones have already been available on the market. Although roaming between different places or the Internet can be easily realized, there are two disadvantages: ① Two physical SIM cards must be inserted into the mobile phone. The cost also increases accordingly. At the same time, when the user changes the number or network, it will cause a lot of waste of SIM cards; ② only two physical SIM cards can be inserted at most, that is, the mobile phone can only have two numbers, which is not convenient for users to roam in many places
