The wireless carrier says it plans to make customers switch to tiered data plans when they upgrade.
Verizon will unveil its data share pricing model by mid-summer.
Verizon's plan is to allow users to buy a chunk of data that can be used with multiple devices on the same account.
Verizon stopped offering unlimited data plans to new subscribers a year ago.
Subscribers who were "grandfathered" into unlimited data plans will now have to choose between tiers.
