Engadget: AT&T to launch VoLTE in Chicago, Minneapolis this month

AT&T is going to roll out VoLTE in Chicago and Minneapolis by the end of May, according to a report by Engadget.  If correct, AT&T will beat Verizon out of the gate for the first U.S. VoLTE HD voice deployment.

MetroPCS deployed a non-standard version of VoLTE in 2012, going with a narrowband codec instead of the mandated AMR-WB.

Launch date for AT&T VoLTE is expected to be on May 23, according to Engadget sources. AT&T says it is “wrapping up” initial market trials with markets ready for VoLTE this year.

No indication when AT&T would be able to deliver VoLTE nationwide, but there’s been a lot of HD voice buzz over the last 24 hours between Sprint, AT&T, and Verizon.
