Company Profile

Corporate Philosophy

Global TaNk provides effective, reliable, and affordable ICT solutions with a competitive edge, designed to support significant business growth for our customers. Specializing in corporate telecom services since 1993, we have always been committed not only to saving clients money but also offering original, highly value-added services.

Three key services represent the pillars of our business, for which we draw on industry knowledge and expertise that has satisfied the diverse telecom needs of more than 5,000 companies to date: ICT consulting—project management to establish more effective communications infrastructure; a full range of UltraCall voice services; and UltraNetCom data services, from Internet access to setting up international networks.

Global TaNk leverages our unique position as an independent Japanese firm with resale agreements among leading carriers to choose optimal telecom services for clients from multiple carriers, which we enhance with our own services to build a solid communications infrastructure. Our commitment to competitively priced telecommunications services allows our clients to invest in their business.
