There is something almost identical to this created by navicom. I believe a bit more expensive upfront, but there most expensive data plan is $100 for the year. It appears that the OP's service charges a minimum of 8.50 per month * 12 months = >$100. I'd rather a larger upfront charge and unlimited(?) usage for $100/year. I'm thinking about getting this and tying it into my alarm system. I originally thought of using my carputer, but I'd rather have a dedicated system for something as crucial as tracking in the event of a theft.
