Hanoi, Vietnam and Bethesda, MD, May 7th, 2019 – Vinaphone (, the leading provider of advanced telecommunications technologies and services to government, enterprise, small & medium-sized business, and consumers in Vietnam announces its partnership with KoolSpan (, to power Vinaphone ProCall, (, the secure mobile communications solution designed to meet the needs of customers in Vietnam.
