300 VoLTE-
capable devices
480 operators have
commercially launched LTE
networks with 550 forecasted by end 2016.
46 operators in
29 countries commercially
launched VoLTE-HD

Industry Stats
Sources: GSMA, Analysys Mason
Annual costs can rise to about
$45 millionin 5 years, for a subscriber base of around 75 million
Typical Tier 1 operator, cost of deploying and operating an on premise IMS solution would be about
$10 million
By 2018, it is expected that about
600 million smartphone users
worldwide will use VoLTE as their default voice service
