1. A method implemented by a device management server and comprising:
receiving, from an internet of things (IoT) device, a data report message comprising a device identifier of the IoT device and a first subscriber identity module (SIM) card identifier, wherein the first SIM card identifier is of a SIM card in the IoT device;
storing the device identifier, the first SIM card identifier, and a correspondence between the device identifier and the first SIM card identifier;
identifying that a second SIM card identifier corresponding to the device identifier is stored, wherein the second SIM card identifier is different than the first SIM card identifier, and wherein device-card binding is set for the IoT device; and
updating the second SIM card identifier to the first SIM card identifier based on the device-card binding being set for the IoT device and after device-card unbinding has been performed on the IoT device.
