Abstract
Present invention relates to an apparatus and a method for establishing communication connections. The method includes: in response to a failure of a SIM card, acquiring first 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. In the case that the multi-SIM terminal device establishes the second communication connection based on the cloud SIM card information, the first communication connection may be disconnected, and the KI card information may be released. With the solutions, a success rate of establishing the first communication connection may be ensured on the premise of saving fees for users.
