NANJING, China — December 11, 2025 — Beijing Huahong IC Design Co., Ltd. (BHDC) has been awarded the title of “2025 China Mobile Supply Chain Core Supplier” at the annual China Mobile Supply Chain Ecosystem Conference in Nanjing.
The distinction was presented during the conference’s Supplier Excellence Awards ceremony, where China Mobile — one of the world’s largest mobile operator by subscribers — recognized select partners for outstanding contributions to supply assurance and product quality.
The event brought together over 1,000 upstream and downstream enterprises and partners from across China Mobile’s supply chain, with senior government and corporate leaders in attendance. Discussions centered on high-quality supply chain development and digital-intelligent transformation.
What the award means
China Mobile operates one of the planet’s most demanding telecom supply chains. Earning “Core Supplier” status signals that a vendor consistently meets stringent requirements for delivery reliability, product quality, and technical capability. For BHDC, this recognition reflects a partnership built over multiple network generations — from 3G through 5G SA.
A track record in secure connectivity
At the heart of the recognition is BHDC’s proprietary Secure Chip Operating System (HCOS), which has achieved EAL5+ certification, delivering high security, a lightweight architecture, and broad platform adaptability. HCOS underpins BHDC’s full-stack SIM card solutions deployed across China Mobile’s network.
BHDC is also a certified supplier of SIM cards and COS (Card Operating System) software for all three of China’s Tier-1 telecom operators, with annual SIM shipments exceeding 480 million units.
What comes next
Looking ahead, Beijing Huahong will deepen collaboration with China Mobile across next-generation use cases, including:
- 5G Super SIM — multi-application SIMs that combine telecom identity with transit, payment, and digital key functions
- eSIM — embedded SIM technology for smartphones, wearables, and IoT, backed by BHDC’s GSMA-compliant eSIM solutions
- Digital currency hardware wallets — secure chip modules supporting China’s digital yuan (e-CNY) on SIM-based form factors
For global operators evaluating SIM and eSIM suppliers, BHDC’s sustained recognition by one of the world’s most rigorous procurement systems serves as a compelling proof point for quality, security, and supply chain reliability.
