This is interesting. Can you use the SIM in some other project? Here's the use case: there are applications where some sensor needs to communicate its readings at a very low bandwidth (say, < 10B per second). It would be great if a $10 SIM would allow me to place this sensor anywhere, and not just within range of WiFi.
