Information processing method and electronic device

An electronic device, comprising:

• a processor supported by the device, wherein the processor obtains a first identity identifier assigned to a terminal by a network side;
• in response to loading the first identity identifier on the terminal and, from a plurality of identity identifiers of the terminal, determines a second identity identifier as an identity identifier of the terminal in a first operation state;
• and obtains, based on the second identity identifier, information used for registering and connecting with a second communication network;
• and
• a communication module communicating with the processor, wherein the communication module establishes a data connection between the first identity identifier and the first communication network;
• and, on the data connection established between the first identity identifier and the first communication network, registers with the second communication network using the information for registering and connecting with the second communication network.
