I'm on a plan that predates the plans being effected by the price increase.

My price has been the same for years. That said, the plan I'm on was also because of an issue way, way, way back (like a decade ago), and actually being responded to by someone in the c suite after making a comment on the ordeal, who then handed me off to exec customer service to get my issue addressed.

I doubt anyone is getting that sort of response and result today, but I personally have no reason to change providers - Verizon and AT&T would be just as bad, if not worse. Verizon even tried to charge me for devices I had paid in full (and I was out of contract timing) when I switched to T-Mobile.
