Is there any reason, beyond corporate greed, for SMS messages to cost so much?

If I get it right, an SMS message is just a short string of data, no different from a message we send in a messenger. If so, then what makes them so expensive? If we’d take Internet plans and consider how much data an SMS takes, we should pay tiny fraction of a cent for each message; why doesn’t that happen?

    GSM SMS protocol is the same on both continents. The reason SMS became free in the US with 4G, was as an attempt to level competition for cell phones that weren’t iPhone, since the iMessage protocol uses data transmission rather than SMS. Now that Android uses RCS, which is also data transmission, the only use for SMS is Android to iPhone texting and dumb phones.
