AT&T Expands America's Best Guarantee to Deliver Faster, Simple Support, with Fewer Transfers

What's New: AT&T is expanding America's Best Guarantee to deliver a faster, simpler experience. Now, customers who call AT&T can expect an answer in 5 minutes or less and if not, they will be offered a callback at a time they choose. Customers who pair AT&T Fiber or AT&T Internet Air and wireless will have one dedicated technical expert to assist from start to finish. If we fall short of these promises, the Guarantee proactively makes it right with a benefit.
