Re: Cost is already paid?
SMS uses the SS7 protocol (for anyone who cares). As far as not being able to triangulate it, I'm not so sure about that, but I'll defer to the experts.

Unfortunately I don't have the technical background for it.
Basically though, the SMS provider is separate from the cellular provider and the SMS message is sent over a different protocol (that's why there is no way to geolocate an SMS message, but you can geolocate a cell phone call). The gateway network for SMS is a different network from that for PLMN. |
