I'm guessing that you or whoever made the assertion is misunderstanding it.
GPS receivers have become much smaller in recent years, but I doubt
they'd fit on a board the size of a
SIM, nor would a phone not designed
for such a bea t be likely to read any data from said
SIM. IIRC, a GPS
antenna itself is larger than a
SIM.
Perhaps this is a confusion based on the current availability of
"location based" services now available from mobile phone operators?
Often incorrectly referred to as "GPS," mobile phone operators can
triangulate a phone's location based on it's distance from wireless towers,
usually for emergency ("911") use.

Location-based services are available- emergency 911-location, some
carriers offer subscription services that display your family's phone's
positions on your phone, Verizon sells a trip navigation service (similar
to GPS navigation systems) etc.

Again, I doubt it has anything to do with the
SIM per se, and, AFAIK, no
carrier allows the use of a "third-party"
SIM of any type.
BTW, a Google search turned up nothing about a GPS built-into a
SIM card.

Many, if not all, modern phones are location-enabled, but they don't
generally let you use the data directly- the carriers use it for e911 or
subscription services. A few Windows-Mobile based phones have "real" GPS
receivers built-in, and many bluetooth phones can connect to bluetooth
GPS receivers (this is the method I use.)
And, if I recall a recent article in RCR News correctly, Nokia was
reportedly planning to make operator-location data available to users on
future phones (so programmers could design GPS-like software for them.)
