AT&T To Pay New or Existing Customers $100 to Add Line of Service

The U.S. wireless price wars continue, with the latest update coming from the AT&T camp as they promise to give customers a $100 credit just for adding a new line of service.

AT&T announced Wednesday that new or existing customers who add a new smartphone, tablet, feature phone, mobile hotspot or wireless home phone are entitled to it.

Of course, that $100 isn't the kind you can slip into your wallet -- it's actually a credit that shows up on your bill!.

“This $100 credit is a way we can reward our existing customers who add an additional line of service for their loyalty, and it’s an incentive for customers of Verizon, Sprint, T-Mobile and other wireless carriers to come to AT&T and enjoy the nation’s most reliable 4G LTE network," remarked David Christopher, chief marketing officer at AT&T Mobility.

The offer is good for both new and existing customers, but ends on March 31, 2014.
