Abstract

The embodiment of the invention discloses a communication method and mobile communication equipment. The mobile communication equipment comprises a first modulation and demodulation module, a second modulation and demodulation module and a radio-frequency link module. The method comprises the following steps that: when the mobile communication equipment arrives at a roaming place, network information of the roaming place, where a mobile communication terminal is, and network communication capability information of the mobile communication terminal are obtained; the first modulation and demodulation module sends card distribution request information to a server through a radio-frequency link in the radio-frequency link module; card information of a virtual subscriber identity module card corresponding to a second communication network is obtained from the server; the second modulation and demodulation module is accessed to the second communication network, which the subscriber identity module card belongs to, through the radio-frequency link; and communication transmission in the second communication network is performed.

Description

technical field [0001] The present invention relates to information processing technology, in particular to a communication method and mobile communication equipment. Background technique [0002] With the development of smart terminals and wireless network technologies, users expect to use the same terminal to access the Internet at different locations. Different locations may be covered by different communication networks, and correspondingly, end users may need to pay expensive roaming data service charges for data transmission, especially in the case of international roaming. [0003] In order to save tariffs, a terminal user may need to purchase a Subscriber Identity Module (SIM, Subscriber Identity Module) card in a roaming region. The subscriber identity module card is bound with the operator. If the user wants to change the operator, the user needs to buy a calling card in the roaming area or go to the operator's business hall in the roaming area to handle related ...
