The Asia-Pacific is one of the fastest growing telecom markets in the world. It includes both developed markets, ripe for ambitious new entrants, and emerging markets which will add more than a billion new subscribers over the coming decade.

However, APAC expansion can be complex, costly and uncertain. That's why many service providers choose to partner with TNZI. We are the APAC voice specialists - with regional experience and carrier relationships built up over more than 20 years.

By partnering with TNZI, service providers can eliminate the need for high, upfront expansion and product development costs. Our new-generation managed voice services enable providers to swiftly and cost-effectively enter and expand in multiple APAC countries.
