while sim cards have been used for stuff like telemetry reporting or telistalking, these tend to require buying a totally new sim card.
What if for just one dollar, you can get a sms only sim card attached to your phone account.
If you are worried about abuses, make it so that it can only send
sms to your real phone.
The idea with this, is to use the sim card for embedded systems like door locks.
I'm sure there are other uses that can be done with this :0

||I bet having one account (and one bill) for several SIMs is baked as well.

||The iPad is the same way, but this idea isn't about data (at

limited to tiny amounts of packet data.
