  Good point.

  No pin number required?

    Even if there's PIN on SIM, tracker must be able to unlock it, and given that GSM module is a pretty common one operated via AT commands over serial line you can easily get it from there.

  Someone tried this with the card in a smart meter. They were still billed for it when they got caught.
