GSMA’s eSIM certification is the global benchmark for security and interoperability. Watchdata has successfully completed the SAS-SM accreditation, which covers the full life-cycle security requirements for eSIM production, issuance and management, ensuring full compliance with GSMA specifications.
Against the backdrop of exponential IoT device growth, eSIM technology—thanks to its remote-provisioning and multi-carrier switching capabilities—has become the cornerstone of global connectivity. Industry forecasts indicate that by 2030, vehicle-embedded eSIMs will see rapid expansion, driven by connected-car adoption, while smart meters, asset trackers, POS terminals and industrial sensors are expected to grow at a CAGR of approximately 20%. Watchdata’s certification is a timely response to these trends, providing IoT vendors with a one-stop, internationally compliant connectivity-management platform.
Released by GSMA in 2023, the SGP.32 specification targets two key pain points in cross-border IoT deployments: complex carrier switching and large-scale device management. Watchdata, an early adopter of the standard, has built its eIM solution on SGP.32 and the widely deployed SM-DP+ (Subscription Manager Data Preparation+) infrastructure, delivering three core innovations:
1. Streamlined connectivity management: standardized APIs allow enterprises to orchestrate eSIM profiles across multiple operators without bilateral integration.
2. Automated deployment: Remote SIM Provisioning (RSP) and bulk activation shorten time-to-market for smart-meter roll-outs and global logistics-tracker deployments.
3. Cost optimization: eliminating physical SIM replacement and logistics reduces connectivity OPEX by more than 30 %.
The platform has already been deployed across multiple verticals. In a flagship automotive programme, vehicles leave the factory with Watchdata eSIMs and dynamically switch to the optimal local network after sale—no physical card swap required. In a pan-Asia smart-government initiative, the solution will remotely provision millions of devices, eliminating connectivity failures caused by incompatible network standards.
“This milestone reflects not only Watchdata’s leadership in secure digital connectivity but also the growing global momentum behind eSlM innovation.”
”said GSMA’s Director of IoT. “Their achievement sets a new benchmark for excellence in the loT ecosystem, reinforcing the importance of trusted, scalable and standards-based solutions in enabling the next generation of connected devices.”

For IoT vendors, the solution significantly lowers the barrier to international expansion:
• Faster time-to-market: devices can ship with Watchdata eSIMs and, upon arrival in the target market, download the local profile OTA—especially with Watchdata’s Bootstrap-less technology that requires no seed profile.
• Higher reliability: GSMA-certified security architecture prevents unauthorized profile tampering, meeting stringent requirements for finance, healthcare and critical-infrastructure applications.
• Open ecosystem: interoperability tests have been completed with leading carriers across North America, Europe and Southeast Asia.
Jinyan Song, General Manager of Watchdata, stated that the company will continue to invest in eSIM R&D, focusing on two strategic directions:
1. AI-driven connectivity optimization: machine-learning algorithms will analyse network behaviour and automatically switch devices to the carrier offering the best signal or lowest cost.
2. Carbon-neutral applications: remote eSIM management reduces e-waste from physical SIM swaps, supporting sustainable IoT growth.
Industry analysts note that this certification could reshape the Asian eSIM landscape. Historically dominated by European and North-American vendors, the infrastructure layer is now seeing Chinese companies gain definition power. As 5G RedCap and other technologies mature, the convergence of eSIM, cloud and edge computing is expected to enable new scenarios such as plug-and-play industrial IoT modules and seamless global consumer devices.
