It's been a while since we've heard much from the ever-embattled VoIP provider, but it looks like Vonage might still have a couple tricks up its sleeve. The company's latest service plan, known as World Premium Unlimited, offers unlimited calling to mobile phones in 42 countries -- and landlines in 80 -- for $55 a month. This plan also provides for unlimited local and long distance service in the US, Canada, and Puerto Rico, and requires callers to use a touch tone phone, hooked up to the internet by way of a Vonage adapter, to make calls to places like the UK, Mexico, and Brazil. It may not be an ideal primary calling solution for most, but it could be enough to put Vonage back in our sights. Full PR after the break.
