United World Telecom (UWT) is a global telecommunications company designing, operating, and supporting international voice infrastructure for businesses worldwide.
Founded in 1996, United World Telecom provides the carrier-grade network, advanced local and international routing, and operational expertise behind modern global voice services, serving over 17,000 corporate clients worldwide. We support international calling, local and toll-free voice, SIP connectivity, and Bring Your Own Carrier (BYOC) solutions across 160+ countries.
Our headquarters is located in Delray Beach, Florida, but our team operates globally, including in Asia (Thailand and India), Europe (Ukraine), Africa (Cameroon), and the Americas (Brazil, Peru, and Mexico). This presence enables close collaboration with local carriers, faster issue resolution, and deep familiarity with country-specific regulations and routing conditions.
We prioritize network reliability, call quality, and routing integrity even when it requires greater operational investment. Every call placed through our network is treated as mission-critical, because for our customers, voice is not a feature, it is core infrastructure.
