Yeah, the old AT&T unlimited plan for $30 a month got increased $5 per year for 10 years and is now $80 plus higher regulatory, admin and bogus fees. Just get Visible from Verizon, $20 per month for 2 years.
This is BAU for all American companies. They will hoodwink you at every turn. Just accept it and move on.
