How long can a physical SIM card be used?

The physical SIM card itself has no usage time limit. It can be used normally as long as the account is not canceled and the bound basic package is within the validity period.

If there is no valid package for more than 3 months, the card may enter the number retention dormant state, and a package purchase is required for activation.

If there is no valid package for more than 6 months, the SIM card will be canceled and cannot be used.
