The biggest thing on both AT&T and Verizon’s 2014 roadmap are to officially launch VoLTE (Voice over LTE). During testing there were setbacks after VoLTE tests rapidly drained battery delaying voice over LTE’s launch. Now that the battery issues are resolved VoLTE may make it’s debut on May 23, according to sources at Engadget. It has not been disclosed on which devices will be able to take advantage of VoLTE, but it should be possible for most 4G enabled smartphones to use VoLTE with an OTA (Over the air) update. The only comment AT&T has made on the news is "We're wrapping up our initial VoLTE market trials and our initial markets will be VoLTE ready this year”. When VoLTE finally debuts the voice quality should be better than current 3G calls due to improved latency and fallback where LTE service isn’t available.
