I should have clarified. A carrier which doesn't support the feature on the phone I want. However, it's a moot point for me. I'm staying with AT&T, and all of their 3G, Faux G and 4G phones support it.
Again it isn't the carriers choice. It is the phone manufacturer that made this decision. This company decided to develop a chip with only one radio. They call it a feature. You call it what you want. I call it how I see it.
This design also lacks a necessary codec and air interface for improved voice call quality and future improved 4g speeds and coverage. This was also not the carrier's choice.
