AT&T has launched High Definition Voice in parts of Miami-Dade, Broward and Palm Beach counties and the Treasure Coast. South Florida is the first area of the state to have access to HD Voice, which enables AT&T customers to experience clear conversations while simultaneously surfing the Web at 4G LTE speeds.
To use HD Voice, both callers will need to be in an AT&T HD Voice coverage area using AT&T HD Voice-capable devices with HD Voice set up on their AT&T accounts. There is no extra charge for HD Voice service. For more information: www.att.com/hdvoice.
