TelServ especially serves carriers and resellers in the telecom market. We don’t facilitate end-users. Why? Because we are convinced that you – as a carrier or reseller – have the experience and expertise needed to service this group of clients. And last but not least, we don't want to compete with you.
We don’t talk about our clients, their turnovers or their volumes.
