From Wikipedia:
The Bluetooth specification was developed in 1994 by Sven Mattisson and Jaap Haartsen, who were working for Ericsson Mobile Platforms in Lund, Sweden.[2] The specifications were formalized by the Bluetooth Special Interest Group (SIG). The SIG was formally announced on May 20, 1998.

I could be wrong on this one, but I believe the SIM was introduced at the same time as the first digital (2G) mobile phone, which was 1990 in the States and 1991 in Europe.
