Verizon Wireless announced today its plans to get rid of its unlimited data plan that was grandfathered to previous users in favor of “tiered” data plans — and Verizon subscribers are NOT happy about it.

FierceWireless reported earlier today that Verizon CFO Fran Shammo was speaking at the J.P. Morgan Technology, Media and Telecom conference and said the unlimited data users who were grandfathered after the company’s switch to tiered plans last year will be required to pick a data-share plan.

Verizon reportedly is launching the data-share plan this summer, which will move the unlimited 3G data plan users to 4G LTE, but they will lose their $30 unlimited plan.

“Everyone will be on data share,” Shammo said.

Users on the Verizon Wireless Facebook page did not respond kindly, and many said they were leaving the nation’s largest wireless carrier.

Shammo did not elaborate on when exactly the change will take place, although with the data-share plans coming this summer, it looks to be soon. The data share plan is more geared at family plans and small businesses — the plan will have one amount of data purchased that is shared among everyone on the plan.

Verizon eliminated unlimited data plans in July of 2011 but kept previous subscribers to the plan. AT&T has done the same but is still keeping its unlimited data intact for grandfathered users. Sprint offers unlimited data to new users.

This announcement comes shortly after the company announced last month it would start charging a $30 fee for users to upgrade their phones.
