据我所知,SIM 卡是一个 Java 卡,它应该实现 ETSI/3GPP 规范和 UICC 配置。
最佳答案
- If the SIM is a Java Card - does it contains a JCRE from the Suns JCRE specification?
2a. If the SIM card has a JCRE - is it actually the OS of the card or there is another layer?
2b. If there is, where can I read about it? Is there an option to interact with the JCRE with APDU and a card reader?
- Are the JCRE and the card manager the same entity or the card manager is a native applet?
If those are different, when an OTA update via SMS received, does the JCRE handle it first and then forward it to the applet or the card manager is the receives it directly?
