AT&T on Saturday announced a price cut for family plans with large amounts of datam, as the the No. 2 U.S. mobile provider tries to regain ground lost to Verizon Wireless and T-Mobile US. A family of four can now get unlimited talk and text, and 10GB of data for $160 a month.

The discounts are available to any customer, including small businesses with up to 10 lines, and customers of other carriers who switch to AT&T.

Customers new to AT&T can get these prices on AT&T's network when they sign up for a 10GB or larger bucket of data and purchase a phone with AT&T NextSM (no annual service contract and get a new device every year for $0 down) or bring their own device or purchase a phone at full retail price.

Current AT&T customers can save with these new plans, too, when they choose a 10GB or larger bucket of data. For example, a family or small business with four smartphones could move to this new plan and save between $40 and $100 per month, depending on their current plan.

In some cases, families will actually pay less if they upgrade. That family of four, already pays $170 monthly for a 4GB plan and $180 for 6GB. If they upgrade, they will pay $160.

Also, all new and existing AT&T customers will receive a $100 bill credit for each new line of service added - whether a smartphone, tablet, feature phone, mobile hotspot or AT&T Wireless Home Phone.

The cuts follow recent price adjustments at all four U.S. wireless providers.
