I’ve been using international phone services of the TC Global Systems in USA since June 2016. From the first day of using their services, I have seen and evaluated how much their communication services are improved over services of their competitors. I can attest to this being true because I make phone calls with different countries constantly.
I can definitely say that TC Global Systems provides fantastic quality services, not to mention their low costs! We can communicate with clients who are on opposite sides of the Earth as if they were next door. I would to recommend the Chief Engineering Officer of this company, Mr. Timur Voloshin as a high level specialist and also as an ingenious inventor who can create constructive solutions for any situation.
