Just heard from a foreign gateway provider.

You are required to get a CSC to transmit into the U.S.

It is being dictated by the U.S. carriers as a group, and there is no way around leasing a CSC from the telcos to send SMS messages.

If you live anywhere, but the U.S., SMS delivery is dependable and less expensive, generally.

While sending SMS messages to the U.S. is now a premium service for the entire world.

Guess who is paying the ultimate price?

U.S. consumers of course.

Fewer new and innovative services will be offered to U.S. subscribers, in my opinion.
