These must be pretty small applications -- don't SIM cards have under a megabyte of storage capacity?

Yes. The memory space is very limited, which is why you cant code with String, int, or garbage collection. As mentioned in the video, the dev environment is limited and it allows to compile complex applications to a very small binary.

I was under impression the biggest cards have up to 1-2 MB RAM, 128 MB flash and relatively fast 32-bit MCUs.

And that was a few years ago.

Edit: Found a PDF from 2006 that talks about even higher spec SIM cards: http://www.spansion.com/products/documents/hd_sim_whitepaper...

The wonders one can do with 64KB. :)

The slide (8) says 72k EEPROM, 6k RAM and 256 k ROM.
