  • Method for distributing virtual SIM card, method for accessing network, and related devices
    Patent number: 10375567
    Abstract: The present invention discloses a method for distributing a virtual SIM card, a method for accessing a network, and related devices. The method for accessing a network includes: determining, from at least two primary virtual SIM cards, at least two candidate primary virtual SIM cards that match a network environment parameter of a visited place of a mobile device; downloading a secondary virtual SIM card by using an accessed primary virtual SIM card that is in the at least two candidate primary virtual SIM cards and that successfully registers with and accesses a network; and accessing a target mobile network of the visited place by using the secondary virtual SIM card. Embodiments of the present invention help improve a network access success rate and network access reliability of the mobile device and reduce operation costs.
