Xplorium is one of the biggest international wholesale VoIP carriers, with a significant international presence: Europe, the United States, the Middle East, Latin America and Africa. One of the company’s specialities is carrying the international traffic of GSM operators in addition to many other varied retails services. In a number of locations the traffic is carried via satellite and this gives rise to concerns about the voice quality and the efficiency of transmission.
