Engadget - A closer look at Willcom’s W-SIM:
"Take a PCMCIA card for cellular data transfer — hardware, antenna, and all — shrink it down to the size of a SIM card, and there’s the W-SIM. It is a complete cellular package (modularized PHS, technically), and Willcom says it’s the smallest in the world at 25.6 x 42.0 x 4mm (1 x 1.65 x 0.15-inch)."
