Abstract:
UIMID of a UIM 50 owned by the owner of a portable phone 40 is stored in an owner information registration area 410b of phone 40. A CPU 405 of portable phone 40, upon receiving content, compares a UIMID of a UIM 50 inserted in phone 40 to the UIMID registered in owner information registration area 410b. The storing of the content in a nonvolatile memory 410 is permitted only when the two UIMIDs agree with each other.
