A leading Android device manufacturer delivers smartphones certified for use across the largest US mobile carriers. With evolving Radio access technologies (RAT) (2G through 5G NR and NTN), carrier certification requirements and frequent Android releases, the client needed a trusted engineering partner to ensure consistent telephony and modem performance across multiple network and device environments, keeping pace with the evolution.

We designed and executed a comprehensive validation program for them covering Android telephony, modem functionality, eSIM, emergency calling and Non-Terrestrial Network (NTN) capabilities. By combining live network testing with certification-grade simulator validation, we helped the client accelerate carrier certification, improve device quality and launch new devices with confidence.

The client required a scalable validation framework to maintain device quality across multiple carriers, connectivity technologies and Android releases. Key challenges included: 

We partnered with the client to establish a comprehensive validation framework that would:

We established a dedicated telephony and modem validation program across carrier-approved laboratories and engineering centers. The framework combined live network testing with industry-standard - simulation platforms  to deliver comprehensive coverage across the Android telephony ecosystem.

Key capabilities

The program became a critical component of the client's Android device release cycle, delivering measurable business outcomes:

By establishing a scalable validation program across carrier networks, certification environments and emerging connectivity technologies, we helped the client reduce certification risk, improve release readiness and deliver consistently high-quality Android experiences. The engagement provided a foundation for future innovations in eSIM, 5G Advanced and satellite-enabled connectivity, enabling faster device launches and greater confidence in an increasingly complex mobile ecosystem.
