BHDC IoT SIM & eSIM

Professional Connectivity for Machines & Things in Harsh Environment

From flexible Plug-in SIMs to soldered Embedded eSIMs (MFF2). We provide the robust connectivity layer for your IoT fleet, featuring 10+ years lifespan, automotive-grade endurance, and remote management capabilities.

Product Ecosystem

IoT SIM

For devices with SIM slots. Made from high-grade PC/ABS, capable of withstanding -40°C to +105°C. Superior to standard PVC, ideal for industrial routers and gateways.

IoT eSIM

Available in standard MFF2 and ultra-small WLCSP packages, designed for space-constrained devices requiring extreme durability and eUICC capabilities. Manage your eSIM fleet remotely with our SGP.32 solution.

Product in Detail

Built for Harsh Environments

Made from industrial High-Temp PVC or ABS. Capable of withstanding temperatures from -40°C to +105°C, corrosion, and vibrations. Perfect for outdoor cameras, vehicle trackers, and industrial routers where normal phone cards would fail.

Long-Term Reliability

Our IoT Flash memory is optimized for high endurance, supporting millions of read/write cycles and retaining data for over 10 years, matching the lifecycle of your device.

Global compatibility & Security

Supports 2G/3G/4G/5G networks, with compliance to 3GPP standards (TS 31.101/102) and native support for USIM/ISIM applications. Hardware-level protection with AES/DES encryption, ECC/RSA algorithms, and 5G SUCI privacy support.

eSIM Intelligence

Our eSIMs support GSMA SGP.32 standards. Manage them via our eIM Platform to switch operators over-the-air, enabling global deployment with a single SKU.Remote provisioning: Supports OTA profile download/activation/deletion. Multi-network flexibility: Store at least 2 profiles for global connectivity redundancy. Enhanced security: Flash memory with 200,000+ erase cycles, multiple algorithms, and True RNG for secure authentication.
