What is domestic roaming? I guess you mean state-to-state within the US? I wouldn't have thought that that would have ever been a thing (at least not after domestic long distance calls stopped being a thing). I always hear Americans say they have unlimited talk and text. Is this really the most popular option or do most plans just include it by default? Might explain why American mobile plans always sound so incredibly expensive to me (i.e. "pay for what you use" a la Ting is actually a disruptive idea in that market because everybody overpays by default).
