We provide essential field services during the product development phase. With over 500 on-site test engineers deployed across Europe, the Americas, Asia, and Africa—90% of whom are local—we ensure rapid response, on-site support, and effective communication and collaboration with OEMs and suppliers.

As a certified GCF Recognized Test Organization (RTO FT & RTO IOP), we not only have extensive experience in field testing but also provide complete test planning and on-site execution for products seeking GCF certification, ensuring a smooth certification process for our clients.

For products requiring telecom operator certification, we offer pre-certification testing to help clients assess product stability and compatibility with specific operator networks. We also assist in debugging and fine-tuning, reducing cost and improving efficiency during the formal certification process.

Beyond field testing, we also offer skilled manpower outsourcing services. Whether for firmware/software testing during product development or fulfilling high-volume on-site testing personnel needs, we provide flexible staffing solutions aligned with project requirements.

Any mobile communication device that enters specific telecom operator sales channels must pass operator certification testing. CTSi Tech is an officially recognized testing partner of telecom operators such as China Mobile, Orange (France), and Telcel (Mexico). We support our clients through the entire operator certification process.

To meet the growing demand for accessible testing services, CTSi Tech has established contact offices in multiple cities around the world, ensuring we can provide prompt and flexible support to clients with varying testing needs.

Whether for Apple iOS or mainstream Android platforms, we offer both application development and app compatibility testing services.

For clients requiring field testing across multiple international locations, we can provide complete manpower planning and test execution services—either based on client-provided requirements or with full assistance in defining the test scope.
