Remember those “save a buck or two” commercials? With MOBIVOX you won’t just save a dollar, you can actually earn bucks too. The Mobile VoIP service, which works from just about any cellular phone, is running a viral promotion where users get $1 of MOBIVOX credit for each friend they get to sign up. OK, this might not be the same thing as a dollar in your pocket, but it will pay for some of the long distance calls you make. This VoIP service bypasses the PC, and works with almost any phone in usage today. The basic service is free, and international rates outside of the MOBIVOX community are what the company calls “competitive.” But if you earn free bucks, those calls won’t cost you anything either.
