1. An electronic device comprising:
a communication circuit;
a first subscriber identification module (SIM) comprising subscriber identification circuitry and including information for providing a first communication service;
a memory; and
at least one processor operatively connected to the communication circuit, the first SIM, and the memory,
wherein the memory stores instructions which, when executed by the at least one processor, individually and/or collectively, cause the electronic device to:
identify whether first SIM data cached in the memory is valid in association with the information for providing the first communication service of the first SIM based on information indicating whether the whether first SIM data cached in the memory is valid, when initializing based on the first SIM,
based on the cached first SIM data being valid, perform initialization associated with the first SIM via the communication circuit using the cached first SIM data, and
based on the cached first SIM data not being valid, perform the initialization associated with the first SIM via the communication circuit using first SIM data associated with the information for providing the first service from the first SIM,
wherein the instructions, when executed by the at least one processor, individually and/or collectively, cause the electronic device further to:
configure the information indicating whether the whether first SIM data cached in the memory is valid to indicate that first SIM data cached in the memory is invalid in case that a profile associated with the first SIM is not in the first SIM;
configure the information indicating whether the whether first SIM data cached in the memory is valid to indicate that first SIM data cached in the memory is invalid in case that the profile associated with the first SIM is downloaded in the first SIM and not activated; and
configure the information indicating whether the whether first SIM data cached in the memory is valid to indicate that first SIM data cached in the memory is valid in case that the profile associated with the first SIM is downloaded in the first SIM and activated.
