SMS Security??

When I send an SMS is it sent securely??

How can I be assured of this?? (What protocols, cryptography is used?)

Would the answer be the same if $1,000 were at stake? How about $10,000?

I've just discovered an old posting (Google Groups) of yours, see
below. Sorry to bring up such an old post!! But, did you ever
discover a solution/publish anything on the topic??

I'm currently looking to conduct my own research into the area, hence
looking around what is already in existence.
