I dropped Verizon several years ago, because after a rate increase, and an incentive from Sprint, as a group discount, which Verizon wouldn't match, or even come close to, in order to keep a long time loyal customer, I switched carriers.
This seems to be another "cost sharing" business decision by Verizon to raise rates for long term grandfathered customers, to get them to drop their grandfathered unlimited plan, which I'm told is going from $29.99 to $49.99 per month, making the price of unlimited data plans increase by 40%.
If true, that is a big price increase!
