Data flow control method, apparatus and terminal

The invention discloses a data flow control method which comprises the following steps: determining whether an avatar application bears a relationship with a main data card; displaying the avatar application with corresponding relationship with the main data card, the avatar application using the flows of the main data card; and concealing the avatar application with no corresponding relationship with the main data card, the avatar application not using the flow of the main data card. With the method provided in the invention, it is possible to properly allocate the networking data flows of double cards or multiple cards. At the same time, the problem with display redundancy of avatar application can also be well resolved, which makes a smart phone interface simpler and brings more use experience to the users. In addition, the invention also discloses a data flow control apparatus and a terminal, which can achieve what has been mentioned above. 本发明公开了种数据流量控制的方法，判断分身应用是否与数据主卡具有对应关系；显示与所述数据主卡有对应关系的分身应用，并且所述分身应用
