The news come from Reuters, when Verizon CFO Fran Shamo during a webcast of an investor conference said a new iPhone would hurt quarterly margins whenever it arrives.
Verizon Wireless allows unlimited Web-surfing for $30 a month for users of its version of the popular Apple phone. But this will change in the coming months.
"We will probably do that in the mid-summer time frame," Shammo said.
Verizon Wireless will replace its unlimited mobile data plans with usage-based pricing around the middle of summer.
Apple Inc has historically launched iPhone models during the summer, coinciding with Verizon Wireless' timeline on its new data plans.
Shammo did not disclose the timing for the next iPhone.
