Truphone is a small mobile VoIP company that was able to start growing after it received nearly $25 million from VC investors in its Series A funding round. The company can now make a real impact on the industry after a Series B round of funding garnered it an additional $32 million dollars. This news follows the company’s recent acquisition of Sim4Travel which “completes its GSM core network”. It also lets Truphone’s service move to more handsets than were previously possible and allows the company to truly compete in the global marketplace. Headquartered in London, Truphone has a small base of American users that is likely to get bigger as a result of these recent changes and investments.
