According to ISO/IEC 7816-12:2005, USB-ICC is another area in sim cards that can be utilized for additional data.

Would this be a viable place to implement extra storage capacity? Seems far-fetched, but interesting.
Pictures please.
A general (and possibly a detail), that includes the board revision and id silk screen.
At least one detail of the portion you are writing about.
