Most SIMs I know are black boxes, with 0 public documentation. Taking into account that they are issued by telecom companies I don't trust them at all.
- foolfoolz 9y agothe reason there are multiple sim manufacturers and SIM cards interop seamlessly into any device is because they are built entirely on published standards. there is tons documentation, usually in the form of giant specifications. look for Secure Element. Java card. global platform. UICC.
- Aloha 9y agoThe standard is out there if you're willing to pay ETSI (or whomever - though the CDMA2000 specs are open and online) the money to get at it. They're not black boxes by any measure of the word.
