An international roaming & interconnect testing solution
Mobile network operators need to ensure their roaming and interconnect services are reliable, which in turn fuels the demand for thorough roaming and interconnect testing. At QiTASC, we implement roaming tests globally. Our pioneering solution outshines all other solutions on the market and propels your business to the forefront.
As global travel increases, the demand for seamless international mobile connectivity grows. Telecommunication networks expand faster than ever. Travellers expect to use their mobile devices anywhere without interruptions or connectivity issues. The ability to validate international roaming services with accuracy, speed, and scalability has become essential.
QiTASC introduces a groundbreaking, lean test automation solution that sets a new benchmark for global roaming testing. We offer a centralized, fully automated framework designed for precision, flexibility, and real-device validation across over 100 countries. Real devices across numerous countries allow all typical human interactions with mobile devices to be replicated and tested, ensuring unparalleled performance reliability and cost/performance ratio.
Our roaming service enables comprehensive testing from mobile to backend systems. It ensures full end-to-end validation of telecom services.
Unlike fragmented testing tools, this integrated solution centralizes management, execution, and analysis within a secure and scalable environment. The system’s layered architecture separates test logic from implementation, streamlining test case development across multiple technologies and ensuring maintainable, efficient scripting. This allows network operators to evolve alongside emerging standards without major rework.
Designed for usability, QiTASC’s framework features easy-to-read scripting in conversational English, allowing testers to create and execute complex scenarios without deep programming knowledge. Test development and management can be performed via both an IntelliJ-based IDE and a secure web interface, giving teams flexibility in how they work.
Automated roaming testing software using real devices
The heart of our operations is the QiTASC international roaming and interconnect platform. Located in Vienna (Austria), it provides a run time environment called intaQt. It enables automated real-device testing that provides end-to-end validation from mobile devices through backend systems. This includes verifying call establishment, data session management, authentication, and billing flows. It is supported by automated CDR verification to ensure accuracy and compliance. Secure, isolated test environments maintain operational integrity and data protection.
Regular automated tests collect real-time quality metrics from partner networks, enabling operators to assess performance objectively. When network quality drops, OTA updates to preferred roaming lists can steer subscribers toward higher-performing networks, minimizing dropped calls, reduced throughput, and latency issues. Dynamic adjustment of environment variables such as APNs, SMSCs, or IMS settings allows rapid adaptation to diverse roaming conditions without modifying test scripts.
Remote device control enables manual interaction for scenario exploration, followed by automation for repeatable tests. Advanced SIM management supports thousands of physical and eSIM profiles, integrated with SIM multiplexers, for accurate testing of registration, authentication, and mobility management across multiple operators simultaneously.
All test results are supported by intuitive reporting and customizable logs. They provide actionable insights for rapid troubleshooting and informed decision-making. This approach ensures high-quality roaming performance, reduces time to detect and resolve issues, and supports agile network adaptation across global operations.
The portable box for roaming testing
The software runs on the IR-box, a portable lab for international roaming testing that can be placed at any location globally. For roaming testing, we select suitable locations and enable telecom operators to test their roaming services in said countries.
What can be tested
The complexity of roaming testing lies in maintaining seamless roaming across diverse network technologies and standards. Variations in configurations, signaling behavior, and service implementations across 2G, 3G, 4G, 5G NSA, 5G SA, and WiFi networks make interoperability testing essential.
The global reach of our roaming service covers the entire technology spectrum required by modern telecom operators. Built with a modular, horizontally scalable architecture, our system adapts effortlessly to new technologies and increased network demand. The multi-tenant isolation and enhanced security protocols include mTLS and certificate management to ensure secure, compliant testing even across complex global infrastructures.
Frequent bi-weekly software releases keep the framework synchronized with the latest network advancements, while its dynamic variable management allows instant adaptation of test cases to different configurations such as APNs, SMSCs, or roaming agreements without modifying the core scripts.
The technology enables telecom operators to test the following:
IR.24 – International Roaming for GSM Networks
IR.24 is focuses on international roaming between GSM networks. The main test cases for IR.24 would typically cover Registration and Authentication, Voice Calls, SMS/MMS, Supplementary Services, Data Services (GPRS/EDGE), USSD (Unstructured Supplementary Service Data), Roaming Tariff Information, Handover Scenarios, International Roaming Billing.
IR.25 – GPRS (General Packet Radio Service) Roaming Exchanges
IR.25 addresses the interworking aspects for GPRS (General Packet Radio Service) roaming exchanges, where GPRS subscribers can roam into other GPRS networks. The test cases focus on ensuring seamless service as users move from one network to another.
