The 4G voice revolution is gaining momentum: high-definition voice service over LTE has been commercially launched by 10 operators in Hong Kong, Japan, Singapore, South Korea, and the US, while many more have invested in the technology to support voice-over LTE capabilities, according to the latest statistics published by the Global Mobile Suppliers Association (GSA) .

The GSA notes that 66 service providers spanning 35 countries have invested in VoLTE studies, trials, or deployments, with 10 operators in Hong Kong, Japan, Singapore, South Korea, and the US, having actually launched an HD VoLTE service. The GSA also notes that there are now 92 different smartphone models that support the 4G voice variant.

If you need a refresher on how VoLTE works, Yahoo! Tech breaks it down for regular folks in the following video -- although it says the three major US carriers have plans to roll it out, so it seems it has already written off Sprint Corp. (NYSE: S).


For a deeper dive into VoLTE, Light Reading has a dedicated section devoted to the topic.


The GSA's numbers might not seem all that compelling -- after all, 10 operators with HD VoLTE is not many -- but 4G voice has been making steady progress around the world during the past few months: Dutch incumbent KPN Mobile has just announced a VoLTE trial, while Vodafone New Zealand says it will have it up and running before the end of the year. (See NTT DoCoMo Launches VoLTE on Qualcomm's Snapdragon and VoLTE: So Close You Can Hear It.)

In the US, AT&T Inc. (NYSE: T) and T-Mobile US Inc. each have a few markets up and running -- four for AT&T and 15 for T-Mobile. Verizon Wireless is planning to launch this year, and Sprint is now rumored to be targeting mid-2015 for its 4G voice launch. (See AT&T to Gain 4G Voice May 23?, Verizon VoLTE Testing Spotted, and Sprint's Hesse: HD Voice Goes Nationwide in July .)

The GSA says that 318 operators have commercially launched LTE networks and services in 111 countries, with 51 going live during the past year alone.

Re: GSA report
Sarah, have the carriers said anything about how the will bill for VoLTE?  It seems like they could do as today with "unlimited calls" or they may choose to take it as data usage?  I would guess the former as the latter would really upset customers.  So the real question is are their billing systems up to date to handle this?

GSA report
The GSA has a great list in its report that details where all the operators are at with VoLTE. You can find it here: http://www.gsacom.com/downloads/pdf/GSA_Evolution_to_LTE_report_280714.php4 (reg. required), but note that it's not exhaustive.

The GSA's Alan Hadden points out that: "For example, Vodafone said: "We will begin enabling VoLTE in Europe from H1 2014 and deployed in many markets in next 12 months." And "MetroPCS launched VoLTE in 2012. Due to spectrum constraints voice service is narrowband and not included in the above list as W-AMR technology is not used. MetroPCS is now part of T-Mobile US which has launched W-AMR enabled HD voice using VoLTE, and is included in the above list."

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
