The HD Voice will initially be available in select areas in Illinois, Indiana, Minnesota and Wisconsin, and will continue to expand on a market-by-market basis.
AT&T was the first to deliver Samsung’s Galaxy family of devices; and the introduction of VoLTE HD Voice in collaboration with Samsung marks yet another key milestone in offering the best selection of Samsung Galaxy series in the U.S. AT&T said that subscribers will not have to choose between faster data speeds and HD voice as they can simultaneously talk while surfing the Web at 4G LTE speeds.
