SIM卡为表示能够执行proactive command且支持SAT，它必须在文件EFphaseTKG EFsst中有相关数据。 Phase文件指的是SIM卡所支持的GSM标准的级数，值为3则指SIM卡支持GSM phase 2和设置下传功能（profile download)。SST文件包含支持哪些GSM性能的准确信息。(SIM card that can support the implementation of proactive command and the SAT, it must file EFphaseTKG EFsst have relevant data. Phase document refers to the SIM card supports the GSM standard series, a value of 3 means the SIM card supports the GSM phase 2 and settings transfer function (profile download). SST file which contains support for GSM performance of accurate information.)
