Reliable OSS BSS systems a key issue for Greek operator WIND Hellas

Reliability is the top priority for Greek operator operator WIND Hellas’ CIO Nikolaos Costaras when it comes to OSS BSS solutions.

Costaras says this reliability is particularly important to the pre- and post-paid billing solutions WIND Hellas offers to its customer base.

"We do not wish to have surprises or outages," he says.

Costaras outlines the benefits to operators from working with a reliable vendor. He also details why WIND Hellas created a cost-control focused tariff and billing offering after the financial crisis hit Greece, and why is has proved popular with customers.
