摘要：
非易失性存储器(25)相关联地存储可移除UIM卡(30)的标识信息和下载内容的内容ID。当请求下载内容数据时，CPU(11)确定与请求的内容数据相同的内容数据是否已经存储在蜂窝电话(10)中。如果与请求的内容数据相同的内容数据没有存储在蜂窝电话(10)中，则CPU(11)下载内容数据。如果已存储，则CPU(11)不下载内容数据，而是确定与该内容数据关联的标识信息是否与当前加载的UIM卡(30)的标识信息一致。如果标识信息不一致，则CPU(11)更新内容ID和标识信息的关联。
摘要（英）：

A nonvolatile memory (25) stores the contents ID of a downloaded content in association with the identification information of a removable UIM card (30). When downloading of contents data is requested, the CPU (11) determines whether or not contents data which is identical to the requested contents data is already stored in a cellular phone (10). If the contents data which is identical to the requested contents data is not stored in the cellular phone (10), the CPU (11) downloads the contents data. If stored, the CPU (11) 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 (30). If the identification information does not match, the CPU (11) updates the association of the contents ID and the identification information.
