A nonvolatile memory stores the contents ID of a downloaded content in association with the identification information of a removable UIM card. When downloading of contents data is requested, the CPU determines whether or not contents data which is identical to the requested contents data is already stored in a cellular phone. If the contents data which is identical to the requested contents data is not stored in the cellular phone, the CPU downloads the contents data. If stored, the CPU does not download the contents data, but determines whether or not identification information associated with the contents data matches with the identification information of the currently loaded UIM card. If the identification information does not match, the CPU updates the association of the contents ID and the identification information.
