1. A method for establishing communication connections, comprising:
in response to a failure of a subscriber identity module (SIM) card, acquiring first key identifier (KI) card information, wherein in the case that locally stored roaming KI card information and non-roaming KI card information are both available, the first KI card information is the non-roaming KI card information, and in the case that the locally stored roaming KI card information is available whereas the non-roaming KI card information is not available, the first KI card information is the roaming KI card information;
establishing a first communication connection to a cloud SIM card management platform based on the first KI card information;
acquiring cloud SIM card information from the cloud SIM card management platform over the first communication connection; and
establishing a second communication connection based on the cloud SIM card information.
