Nexmo and CSG Partner to Support Explosive Growth of SMS

ENGLEWOOD, Colo. (October 24, 2013) — Nexmo, a pioneer in cloud-based applications for OTT providers, and CSG Systems International, Inc. (NASDAQ: CSGS), a global provider of interactive transaction-driven solutions and services, today announced that Nexmo has expanded its relationship with CSG to include CSG Assure for fraud-protection and quality assurance.

CSG Assure enables some of the biggest and best-known global communication services providers to test for and guarantee quality of service. CSG Assure’s network covers 420 mobile networks in 130 countries, which helps Nexmo verify the worldwide delivery of time- and content-critical SMS on behalf of its rapidly growing corporate customer base.

“CSG Assure is like an insurance policy for our existing customers, all of whom require SMS in real time with appropriate content,” said David Vigar, director of carrier relations at Nexmo. “We have a culture of customer focus and innovation that calls for scalability and flexibility to match the exploding expectations of our growing customer base.”

Nexmo uses CSG Assure as an independent test platform that allows it to proactively send test SMS through various routes. Mobile operators and SMS aggregators can then verify results that include precise delivery time, textual content verification, address verification, character set validation, concatenated messages delivery testing, and binary content verification.

“SMS aggregators are managing an increasing amount of SMS traffic around the world, and our SMS testing capabilities are unparalleled,” said George Fraser, vice president of Europe, the Middle East, and Africa at CSG. “CSG Assure has become the de-facto standard for SMS testing in the industry; the timely and relevant content we provide allows our clients to maintain competitive differentiation while investing in innovation.”

CSG Assure is available in the cloud and as a subscription-based model that supports speed-to-market for new offerings and seamless hardware and software updates. Nexmo also benefits from fraud protection, quality assurance, and increased operational speed and efficiency. In addition to reducing manual error-prone tasks, Nexmo will be able to adapt in near-real-time to events such as quality dips to protect its margins and service levels.
