Your wireless bill may be going down and ABC's Rebecca Jarvis explains. Reporter: Call them a casualty of the fierce competition for your mobile phone business. Welcome to the family. I've been hearing good things about sprint. Reporter: Sprint ditching the so-called family plan and now in place of that talking hamster. Better call quality. It's fast, right? Reporter: Launching a price war to lure customer as way from rivals. For $60 a month sprint unveiling unlimited talk, text and data. That's 20 bucks cheaper than the same plan at T-Mobile plus this extra sweetener from sprint, dump the competition and get up to $350 back. All the carriers are all competitors doing everything they can to lock up subscribers. Reporter: T-Mobile fighting back with its own new offer. Get a friend to ditch sprint, verizon or AT&T, you'll get unlimited data for a year. You're not making phone calls anymore. You're sending messages and checking Facebook and streaming video and that eats up a lot of data so people are trying to find the best data plan and the best value. Reporter: The best news about this battle for your business, the winner may actually be you.

Reporter: For "Good morning America," Rebecca Jarvis, ABC news, New York.
