An industrial-grade IoT card is a dedicated SIM card designed for industrial scenarios, featuring extreme environment adaptability, anti-interference, high stability, and long lifespan. It provides continuous and reliable network connectivity for industrial equipment such as machine tools, sensors, and robots under complex conditions like high/low temperatures, humidity, vibration, and electromagnetic interference, supporting core functions including equipment monitoring, data collection, and remote control.

Compared with consumer-grade IoT cards (mostly used in smart homes and wearable devices), it has significantly improved design standards, durability, security, and management capabilities. Its core is to meet the rigid demands of industrial production for "uninterrupted connection" and "data reliability".

Functions in -40℃~85℃, suitable for high-temperature workshops, outdoor cold, cold chain warehousing, etc.

Complies with IEC 60068-2-6 anti-vibration standards, with anti-impact performance and IP68 dustproof & waterproof rating, avoiding poor contact caused by vibration or dust.

Surface uses acid/alkali-resistant and anti-oxidation materials, suitable for long-term use in corrosive environments like chemical plants and electroplating workshops.

Supports 2G/3G/4G/5G, NB-IoT, LoRa, etc., with automatic network switching to prevent disconnection.

Built-in high-performance RF modules improve communication in weak signals; resists electromagnetic interference via frequency hopping and filtering.

Smart algorithms enable millisecond-level reconnection to reduce downtime.

Uses industrial-grade chips verified by accelerated aging tests, ensuring over 10 years of service.

Supports deep sleep mode, reducing energy consumption in intermittent communication scenarios (e.g., smart water meters) to extend battery life.

Embedded design reduces plug-in loss; remote OTA upgrades and fault diagnosis lower on-site maintenance frequency.

Built-in SE security chip supporting SM4, AES-256, etc., with tamper-proof storage for device identity information (IMSI, keys).

Card and base station perform bidirectional identity verification via encrypted keys to prevent illegal access.

Uses DTLS, IPSec, etc., for end-to-end data encryption to avoid interception during transmission.

Operator platforms monitor card status in real time; abnormal situations trigger remote freezing and alarms.
