Network connectivity is more important than ever

We believe that the network is the bedrock of a modern organisation, especially for carriers and for service providers.  The big challenge for operators today is to meet their customers’ demands for the latest online services and business critical cloud applications which inevitably consume ever-expanding bandwidth. They need to do this in a way that both delights the customer and that makes commercial sense for their own business.

We pride ourselves on using the most innovative and sophisticated technology, fuelled by continual investment that drives faster speeds and unlimited scalability. Our fibre optic network, submarine cables, wireless, radio access and trunk technologies provide unique operating infrastructure that offers complete resilience and the best possible performance, at a price point that works for our customers.

The quality of our network is further endorsed by our partnerships with market-leading vendors like Cisco and Alcatel, facilitating end-to-end solutions that provide local and global connectivity, and world class customer experience.
