The invention discloses a method for distributing and accessing a virtual SIM card to a network and related equipment, including: determining at least two candidate primary virtual SIM cards that match the network environment parameters of the visited place of the mobile device among at least two primary virtual SIM cards; SIM card; through at least two candidate primary virtual SIM cards to register and connect to the network successfully, access the primary virtual SIM card to download the sub-virtual SIM card; use the sub-virtual SIM card to access the target mobile network of the visiting place. The embodiments of the present invention are beneficial to improving the success rate and reliability of mobile devices entering the network, and reducing operating costs.
Description
Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for virtual SIM card distribution and network access and related equipment. Background technique [0002] In mobile communication technology, the mobile device is equipped with a user identity module SIM card, and the SIM card can be used to register to the mobile network of the operator for networking. Users only need to buy a SIM card from the local mobile operator and install it in the mobile device to use the voice and data services provided by the operator. In order to obtain the SIM card more conveniently, a virtual SIM card came into being. Users do not need to purchase a physical SIM card, just download the SIM card data to the terminal via the network (such as wireless fidelity Wi-Fi, Internet, etc.) , You can achieve the same effect as the physical SIM card and use the network service provided by the operator. [0003] In the international roaming...
