V-Star Mobile Calling
V-Star provides an Android user with a real phone number for free calling among subscribers and hidden calling to non-subscribers. It is especially useful for people who need a different phone number for a social network site, online buying and selling, a second business or online dating.
The V-Star app provides free voice calls and text messaging to other app users, in addition to a variety of paid calling plans for users that want a temporary phone number to connect outside of their comfort zone. When users install the app, they are given a choice of several robust plans.
