7 carrier-billing firms that are witnessing growth in their customer bases and investments

Wouldn’t it be convenient if we could pay for merchandise using just our phone and our existing phone account? Well, there is hope. Giants such as Facebook, Google, Amazon and others are signing deals with carrier-billing players, and the carrier-billing players mentioned below are targeting convenience for the consumer.
