>The other question, given the fact that they’re both GSM-based, is whether or not you know if AT&T or T-Mobile have cheap ‘machine’ plans for use by these types of devices.

AT&T and T-Mo both have cheap MVNOs (resellers.)  Airvoice Wireless resells AT&T
and has a $10/mo plan, texts charged at 2c each with any extra rolling over to
the next month.

Tracfone has a variety of AT&T bring your own device plans, of which
one of the the cheapest is $18 every 90 days, including 180 texts, any extra
rolls over.  If you need more than that, you can top up 1000 texts for
$10 at any time.

These are both SIM-only plans, put the SIM in whatever device you want.
