AI Technical Summary

Technical Problem

In the existing technology, the hardware design of dual SIM dual standby mobile phones limits the flexibility of eSIM cards, making it impossible for users to dynamically adjust SIM card binding, increasing hardware costs and energy consumption, and the multi-eSIM card storage function is not fully utilized.

Method used

By displaying multiple candidate SIM card information on the terminal device and responding to user operations to modify the modem configuration parameters, the SIM card switching of the target card slot can be realized, and the physical SIM card and eSIM card can be dynamically bound, avoiding hardware insertion and removal operations.

Benefits of technology

It achieves a similar multi-SIM standby function with fewer card slots, reducing costs and energy consumption, and improving user experience and flexibility.

Abstract

The invention discloses an SIM card switching method and device, terminal equipment and a storage medium, and the method comprises the steps: displaying the information of a plurality of candidate SIM cards corresponding to a target card slot, and the plurality of candidate SIM cards comprise a physical SIM card and an eSIM card supported by a terminal; and in response to an operation of selecting a first SIM card from the plurality of candidate SIM cards, modifying configuration parameters of the modem so as to switch the SIM card bound with the target card slot from the second SIM card to the first SIM card. By the adoption of the method, a user can freely switch the SIM cards bound with the card slots in the terminal, the function similar to the standby function of multiple SIM cards can be achieved with a small number of card slots, cost and energy consumption are remarkably reduced, and user experience is improved.
