Imagine if every state had a different cell phone carrier or go back even further to when it was long distance even just blocks or cities over. Now imagine a technology comes in that doesn’t care what carrier you are on, or if it’s long distance.

That is kind of what happened to countries. Especially if you have people who work in one and live in another or have clients in another.

So even though now maybe it isn’t long distance, or carriers talk to each other, everyone is used to the way they have been doing it for free.
