AT&T announced what it claims is the first nationwide package including TV and mobile services in the US.

Following the end-July completion of its DirecTV acquisition, the US operator moved rapidly to unveil a new TV-mobile package which will launch on 10 August, dubbed All in One.

The offer costs a hefty-sounding $200 per month but includes up to four TV receivers, unlimited talk and text for four mobile connections and 10GB of shareable data.

Acquiring US satellite TV broadcaster DirecTV gives AT&T options in how it combines TV content with mobile and broadband in innovative ways. The All in One plan is the first example of how this will work.

AT&T is not the only operator thinking down similar lines. Arch-rival Verizon’s recent acquisition of AOL was at least partially driven by delivering cross-screen content, including to 4G devices

AT&T’s model for All in One means that users joining via an AT&T retail store can download an app to mobile devices straight away, enabling them to watch select TV content when they leave the store. Later AT&T technicians will come to their home to install the TV service.

The company said it is the only provider in the States at present that can deliver a TV-mobile package nationwide with one point of contact for customer care, and single monthly bill.
