Verizon's Voice over LTE (VoLTE) platform has been in the works for a while now, and according to industry insiders, it's about ready to hit the big time. Catharine Trebnick, an analyst at Northland Capital Markets, told Light Reading Mobile this week that the service has already launched on a trial basis in two cities, and that Big Red plans to roll it out on a nationwide level in 2013. According to Light Reading Mobile, Trebnick's claims were later corroborated by a second, anonymous source. Verizon, as you may recall, had previously pegged 2012 for the commercial launch of its new platform, and could still achieve that goal with launches in select markets, before going live on a nationwide basis next year, as rumored. The company, however, is playing its cards close to the chest, saying in a statement that it's "continuing to work on VoLTE and the services it brings, and will share any launch or availability plans in due course."
