A piece in the Korean Times calls attention to the largest LTE audiences. Verizon has the most, followed by NTT DOCOMO and SK Telecom.
SK Telecom already has VoLTE and HD voice deployed, with six handsets: Samsung Galaxy S3 & Galaxy Note 2, LG Optimus Vu & Optimus G, and the Vega Race 2 & R3. The largest LTE carrier in South Korea, SK Telecom has over 5 million subscribers – half the nation’s total user market – as of August this year. Later this year, SK will add Rich Communications Services (RCS) to its LTE offerings.
NTT DOCOMO received VoLTE client software back in June and an IMS and VoLTE test Kit at the end of August, according to press releases from Ecrio. The real time communications software company says it has supplied its Mobile Communications Client Suite (MCCS) to SK Telecom and Verizon Wireless, with deployments on more than 50 million handsets.
No word on when NTT will launch operational VoLTE service, but it seems to have all the necessary tools.
