You can find the specification for GSM and 3G technology under
ftp://ftp.3gpp.org/specs/archive/


The "SIM API for Java Card(TM)" is specified in 03.19 release 98,99 and in 43.019 for the releases 4 and 5. There are several version under each release. In the specs you find the HTML docs of the API's as well as the export files. You have toknow which release of the API is supported by the card.


For Applet loading in a Java SIM card you have to check 03.48 the secure loading protocoll based on SMS.


To better understand the API and to see some examples of how to use the API and to load an applet you should take a look into 11.13 the test-specification and test-suite for 03.19, it uses 03.48 to load the test-applets into the card.

You need to get a copy of the GSM standard 03.19 (now known as TS 101476. You can get this from the ETSI web site.

Annex A contains the HTML docs for the APIs and the java code required to compile. Annex B contains export files.

Hope that helps.

Jim.
