Days after closing the AT&T-Time Warner merger, AT&T is rolling out a newest video offering called WatchTV, available in the U.S.

You can stream through the WatchTV app or on select browsers at no additional cost with our two latest unlimited wireless plans. The plans - AT&T Unlimited &MoreSM and AT&T Unlimited &MoreSM Premium - are scheduled to launch next week.

WatchTV features 30+ live channels, will be compatible on virtually every current smartphone, tablet or web browser, and certain streaming devices. In addition to live programming, WatchTV includes over 15,000 TV shows and movies on demand.

WatchTV, which will be free for customers of the new wireless plans, will cost $15 per month as a standalone product. Customers who sign up for the higher-priced wireless plan can also get HBO for free.

With &More Premium, you'll also have the option to add one of several premium services for no extra charge. Premium services include HBO, Cinemax, SHOWTIME or STARZ as well as music streaming services like Amazon Music Unlimited and Pandora Premium.

In addition to that, you'll get 15GB of high-speed tethering, access to high definition video, and a $15 monthly credit toward DIRECTV, DIRECTV NOW or U-verse TV.

WatchTV is available with AT&T's two latest unlimited wireless plans:

AT&T Unlimited &More Premium offers:

• Option to add WatchTV
• Option to add one of several premium services
• $15 monthly credit toward DIRECTV, DIRECTV NOW and U-verse TV
• 15GB of high-speed tethering
• High-quality video

AT&T Unlimited &More:

• Option to add WatchTV
• $15 monthly credit toward DIRECTV NOW
• Up to 4G LTE unlimited data

At launch, full details on our wireless plans will be available on att.com/unlimited. Details on WatchTV as a $15/month standalone service are also coming soon.

A federal judge earlier this month approved the merger of AT&T and Time Warner, handing AT&T a win after the U.S. Department of Justice sued to stop the deal, saying a merger would give AT&T unfair leverage over rival pay-TV providers.

WatchTV as a standalone product will compete with other low-cost video streaming options, including Dish Network's Sling TV, which costs $20 for the base package, and Philo, which costs $16.
