We design and deliver solutions that give operators clear insights and comprehensive control over their signalling, with a focus on security, roaming, SMS monetisation and analytical applications.
We’re rated as a top innovator and Tier 1 vendor in Signalling Firewall, Steering of Roaming and SMS Firewall in independent research. We proudly serve more than 800 million subscribers worldwide.
We have continually broken new ground since our inception in 2005, when we brought together a team with a depth of expertise in signalling, technology, and IP not seen elsewhere.
We are not held back with preconceived notions of how things should or shouldn’t be done. With this, plus our creativity, and huge input from customers, we will remain leaders in innovation, and the commercial and common-sense choice for mobile network operators.
