So I am on hold with VZW last night, and I hear that Verizon has America's largest Mobile to Mobile calling community. Then I start thinking, "What about Sprint's Any Mobile Anytime offering?" I suppose as long as it only applies to Everything Data plans VZW can still get away with it. Perhaps if Sprint expands it to all plans (down the road certainly. I understand that they're probably hoping to convert some existing customers from grandfathered plans, which makes sense) then VZW will either need to change their advertisement or adopt an Anymobile Anytime offering of their own.
