Abstract: Disclosed are a method for determining an access method of a mobile terminal, a storage medium, and a mobile terminal. A database comprising APN types and APN access identifiers is pre-stored in a mobile terminal, such that when a SIM card is inserted into the mobile terminal, the APN type and the APN access identifier corresponding thereto can be searched in the database according to information about the SIM card, thereby determining that the access method of an operator corresponding to the SIM is VoLTE or VoWiFi, distinguishing between VoLTE and VoWiFi, reducing the probability of access failure of the mobile terminal.
