1つのIoT SIMによる信頼性の高いグローバル接続

An IoT SIM card is an IC (Integrated Circuit) chip that holds wireless carrier credentials to provide access to cellular networks for IoT devices like fleet or asset trackers, health wearables, or security cameras.

A SIM card mainly stores carrier credentials in the form of a unique identifier called the ICCID (Integrated Circuit Card Identifier), an IMSI (International Mobile Subscriber Identity) and an authentication key that validates the IMSI toward the mobile carrier.

eUICC eSIMs—not to be confused with embedded SIMs that are simply pre-soldered SIMs with a smaller form factor—are SIMs of any form factor that can hold several SIM profiles on their hardware and switch the profile as needed, as standardized by the GSMA.

Twilio offers IoT / M2M SIM cards and SIM profiles to provide maximum global cellular uptime for IoT devices on one SIM, with a single API for central SIM management.

The main purpose of most IoT devices is to collect data from remote locations. Look for IoT data plans that offer simple per-MB-per-SIM pricing that’s unified across all carriers for predictable cellular cost.

Any device that needs connectivity in remote locations or places without other reliable connectivity uses a SIM for wireless access. Cellular IoT use cases include fleet and asset tracking, micromobility, health wearables, connected building technology, etc.
