The best thing worth having after the invention of Mobile Devices is free calling plans. Unfortunately, that function is available in Skype only but that is not a reason for getting upset. If you happen to live in Canada, USA or Puerto Rico, than consider yourself a lucky person because with the help of VoX you’ll be able to enjoy pretty cool mobile tariffs over Wi-Fi of 3G connections. All you have to do is to download the Nimbuzz VoIP applications and sign up for one of the following “Domestic” tariff plans. Pay as you go: $4.95/Month @ $.05/Min Mobile Out 500: $9.95/Month @ 500 included minutes, $.05/Min overage Mobile Out Unlimited: $24.95/Month International pricing is also available here. For further and wider information, please, check the official VoX site. It does look like in the closest future Wi-Fi calls will replace the regular tariff plans. Is it good or is it bad – who knows. Time will show.
