Improved audio quality is a hard thing to measure. Lots of cell phone carriers claim to have it. But only T-Mobile and Verizon actually offer nationwide VoLTE (Voice over LTE) — the relatively new calling standard that, when possible, places calls over 4G LTE data networks, instead of the traditional circuit-switched networks.
We’re still a long ways away from the day when you’ll get pure HD voice with every phone call. These days, there are so many limitations that HD voice may not actually be very noticeable. Nevertheless, our guide will give you everything you need to enable HD voice on your iPhone 6. We’ll also outline the limitations. Thankfully, those limitations are shrinking. Expect to see more VoLTE ready phones in the next few months.

Verizon announced today that it plans to roll out support for Voice over LTE (VoLTE) ahead of Apple’s expected introduction of the feature alongside iOS 8 and iPhone 6. 9to5Mac first reported back in April that Apple is targeting voice-over-LTE support for iOS 8 and future iPhone models:
Another significant addition being considered for iOS 8 and the next-generation iPhone is voice-over-LTE support (VoLTE), according to carrier sources. Currently, when an LTE-capable iPhone needs to make a phone call, the actual call is placed over last generation networks such as 3G. With VoLTE, calls will be transmitted over the same type of network that LTE data is processed through, and this can allow for benefits such as improved call quality.
Two new wireless industry measures being pushed by China’s government could hamper the growth of Apple’s iPhone in that country, according to UBS analyst Steven Milunovich. In a note obtained by Barron’s, Milunovich cited the work of his fellow at UBS who study the Chinese telecommunications market. The analysts noted that the Chinese government is “urging the three telcos to reduce their sales and marketing costs.” China’s three largest telecommunications companies are China Mobile, China Unicom, and China Telecom.
As noted by Milunovich, the government’s push to reduce sales and marketing costs will likely affect the three carriers’ abilities to offer the subsidies that reduce the upfront cost of mobilein a market where various taxes make many higher-end otherwise unaffordable for most . As a maker of relatively expensive premium smartphones, Apple is especially vulnerable to any reduction in subsidies.
