SMS is international, not just limited to the U.S.A. A SMS message is just like any mail sent from one postal system to the other, because its a transfer of something (data or snail mail) between a sender and a receipent. So if the mobile carriers wanted they could setup a similar system.
You shouldn't look at it like an exchange between domestic providers or international providers it is an exchange between service providers, be it two cell phone carriers or two postal systems.
