Ready for clearer voice calls? AT&T announced Thursday that it will start to activate high-definition voice (HD Voice) features, using voice-over-LTE technology (VoLTE) in select markets starting next Friday, May 23. AT&T said the first markets to offer the feature will go online in Illinois, Indiana, Minnesota and Wisconsin, though it did not name specific cities or why those markets were chosen specifically.
AT&T said it’s teaming up with Samsung on the HD Voice activation and that the first device to gain the capability is Samsung’s Galaxy S4 mini, a smartphone that launched last year and, until now, we weren’t aware had the capability baked in. The carrier promised that additional devices will offer HD support in the near future, though it didn’t name which ones. Hopefully most of the devices it has been selling for the past year will work without any issues, and we presume most, if not all, of Samsung’s Galaxy devices will be on that final list.
T-Mobile and Sprint market HD Voice capabilities though neither take advantage VoLTE technology. Verizon is also expected to roll out its own VoLTE HD Voice service sometime this year.
