Last month T-Mobile began offering rollover data via its flexible "Data Stash" program, and then two weeks ago AT&T introduced a more limited rollover plan of its own.
What about Verizon - will they ever get on board the rollover train?
Don't bet on it.
Verizon CFO Fran Shammo was interviewed by CNet yesterday, and he squashed all hope that Verizon would ever play ball:
"We're a leader, not a follower ... We did not go to places where we did not financially want to go to save a customer. 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."
Shammo pointed out that Verizon never followed AT&T's lead on rollover voice minutes either, so don't expect a change of heart anytime soon.
He also labeled Google's new partnership to rebrand and sell Sprint and T-Mobile service as Google just "stirring the pot" to increase competition, and that Verizon had no interest in partnering with Google either.
Verizon knows they have a network that customers are willing to pay a premium for - and they are clearly willing to try and remain above the competitive fray.
But though Verizon is talking tough, and is clearly not interested in a competitive back-and-forth price war - Verizon did bow to consumer pressure and matched AT&T in offering double data deals in October.
Hopefully they won't keep us waiting until next October for a similarly good deal.
