Method and device for calling SIM card, method and device for pushing information, and SIM card allocation system

A method performed on a server for pushing information, comprising the steps of:

• receiving, by the server, current network access data uploaded by a mobile terminal;
• parsing and processing the current network access data to generate a network information database by the server;
• and
• pushing, by the server, the network information database to the mobile terminal in order that the mobile terminal calls a target SIM card that matches with the external network to perform network registration according to the network information database.

A SIM card allocation system based on massive data analysis, comprising:

• an intelligent terminal configured to parse a currently searched external network and generate a parsing result;
• to read a network information database pre-stored in the intelligent terminal;
• and to call a target SIM card that matches with the external network to perform network registration according to the parsing result and the network information database;
• and
• a server configured to receive current network access data uploaded by the intelligent terminal;
• and to parse and process historical network access data and the current network access data so as to generate a network information database and push the network information database to the mobile terminal in order that the mobile terminal calls the target SIM card that matches with the external network to perform network registration according to the network information database.
