Roaming testing
Roaming Testing verifies that mobile connectivity works without interruption across different countries, networks, and technologies.
Challenge
Multi-operator complexity
Different operators, technologies, and configurations create high integration effort across roaming interfaces.
Limited visibility
Operators lack transparency across international networks and signaling flows.
Manual testing & low scalability
Manual testing cannot cover all roaming scenarios, technologies, and locations efficiently.
Service errors
Basic service disruptions (voice, SMS, data) can lead to decreasing customer satisfaction.
Solution
Test interoperability
Automated tests validate roaming scenarios across partner networks 24/7 to ensure seamless interaction.
Centralized, real-time monitoring
Signaling, reporting, performance metrics, and KPI tracking across all networks.
Scalable test execution
Continuous automated testing enables high test coverage across multiple countries and networks.
Real devices in real networks
Testing with real devices and SIMs in real networks ensures accurate validation of user experience and charging behavior.
What we test
Roaming Testing validates basic services across technologies and layers.
IR-box: Real phones in real networks
Our test automation framework allows operators to perform real-live roaming tests without complex infrastructure setup. It runs on the portable lab for international roaming, the IR-box. It is positioned in real networks.
Mobile devices, SIM cards, and other hardware is inside the IR-box. The testers don´t need direct access to the devices, enabling real-device testing in any location worldwide.
