If you’re a Verizon Wireless customer who was grandfathered in with an unlimited data plan after the company eliminated the option for new customers, enjoy it while it lasts — the company will be moving you to a tiered plan soon.

Speaking at the JP Morgan Technology, Media and Telecom conference on Wednesday, Verizon CFO Fran Shammo said customers with unlimited 3G data access will be required to switch to a data-share plan after transitioning to the company’s 4G LTE service.

“LTE is our anchor point for data share. So, as you come through an upgrade cycle and you upgrade in the future, you will have to go on to the data share plan,” Shammo said. “Everyone will be on [it]. A lot of our 3G base is on unlimited… [and] when they migrate off 3G they will have to go to data share.”

So when will that happen and how much will it cost? The data share plan is scheduled to launch in mid-summer, but pricing details have yet to be announced.
