An objective of this application is to provide a SIM card switching method and apparatus, and an electronic device, so that the electronic device can quickly and accurately perform SIM card switching. The electronic device comprehensively determines, based on a use status of a radio frequency and a network connection status, whether a SIM card needs to be switched. When the radio frequency is used by a specific service, a network connection is temporarily abnormal. However, this temporarily abnormal network connection does not affect operation experience of a user. In this case, if the SIM card is switched, traffic of the SIM card is wasted, and time consumption during SIM card switching also increases a user operation delay. Consequently, determining whether to switch the SIM card only based on the network connection causes incorrect SIM card switching. In this application, incorrect SIM card switching can be avoided.

The present disclosure relates to application server access methods and terminals. One example method includes in response to a terminal failing to connect to an application server by using an IPv6 address, setting an accessed domain name to a restricted domain name, and, when the accessed domain name is re-accessed later, connecting to the application server by directly using an IPv4 address.
