Abstract

The invention discloses a communication method and a communication device based on a channel SIM card. The method comprises the following steps of after first terminal equipment starts up, acquiring a first mobile country code MCC corresponding to a current position where the first terminal equipment is located and an MCC list supported by a first channel SIM card latest issued by a cloud; judging whether the first MCC is within an MCC list range; if yes, using a first channel SIM card to communicate with the cloud; if no, polling at least one preset channel SIM card, selecting a second channel SIM card corresponding to the first MCC, using a second channel SIM card to build a communication connection with the cloud, sending a request message to the cloud, acquiring a third channel SIM card issued by the cloud, and using the third channel SIM card to communicate with the cloud. According to the method and the device provided by the invention, the condition that the terminal equipment needs to poll all the channel SIM cards in the terminal equipment when the terminal equipment starts up each time is avoided, and startup time of the equipment is greatly saved.

Description

technical field [0001] The present application relates to the field of mobile communication and cloud sharing, and in particular to a communication method and device based on a channel SIM card. Background technique [0002] For people who often go abroad, they often need to use international roaming communication services for business communications, which will cost high international roaming charges. In order to reduce the cost of international roaming charges, a SIM (Subscriber Identification Module, SIM technology for customer identity module) cards. By assembling the SIM card on MiFi devices, such as mobile terminals, and providing users with data traffic services, it can reduce roaming charges abroad. [0003] Generally, when the MiFi device is turned on, it needs to use traffic to communicate with the cloud, and the cloud will assign a local SIM card to the MiFi device through a series of algorithms. Specifically, using eSIM technology, the channel SIM cards of some...
