Network operators T-Mobile and AT&T have both announced data rollover programs, to help customers who do not use all of their data in one month to keep the data for the next.

Verizon Wireless has confirmed it will not get on board with the data rollover program, according to Chief Financial Officer Fran Shammo that claims the company is "a leader, not a follower."

"We did not go to places where we did not financially want to go to save a customer," Shammo said. "And there's going to be certain customers who leave us for price, and we are just not going to compete with that because it doesn't make financial sense for us to do that."

The change in tone comes after several investors called for a return to "rational pricing" in the mobile industry for AT&T or Verizon Wireless, and also to stop competing on price with T-Mobile.

Even though Verizon Wireless is first place in the U.S. carriers battle, both AT&T and T-Mobile added more customers in 2014, showing the carriers are able to beat Verizon on price year-on-year.

Verizon is not exactly losing subscribers however, and it seems executives are not bothered about T-Mobile CEO John Legere's new plans to scare off the competition.

Data Stash allows customers to rollover data to the next month, T-Mobile allows this for a full year, AT&T for two months. Sprint has not announced its own deal, but it is likely something is in the works from the third largest carrier.

Google is currently looking at the prospects of launching its own MVNO wireless network, tapping into Sprint and T-Mobile's network. The wireless network will work alongside Google Fiber, its 1Gbps broadband service.
