I know at&t VoLTE is already deployed in Chicago, Minneapolis, Atlanta, and Dallas, when will it be deployed nationwide? Anybody know their timeline to when it will be deployed and why only a few markets are active now? It makes sense that Atlanta and Dallas are deployed because those are headquarters of at&t mobility and at&t inc respectively. Chicago/midwest is at&t's beta test market for literally everything. These cities got deployed in mid-may, it is now November, so what is taking them so long for rollout? I want to finally be able to make HD voice calls and use LTE data during voice calls
