What is an iSIM

Are you curious about iSIM and its implications for IoT connectivity? Look no further! In this post, we’ll explore what iSIM means and the differences between iSIM and eSIM, as well as where physical SIM cards fit into the connectivity landscape.

💡 What is an integrated SIM? ðŸ’¡

An integrated SIM (iSIM) is an alternative form factor to traditional SIM cards. Instead of physically placing a SIM card into a device, as with mobile phones or IoT devices, iSIMs are placed directly onto the device’s System-on-a-Chip (SOC). This removes the need for a removable SIM card and simplifies the device’s design.

⚙️ What’s the Difference Between eSIMs and iSIMs? âš™ï¸

While eSIMs are soldered to the circuit board of a device, iSIM technology offers greater flexibility and security. With iSIM, the SIM is integrated into a Tamper-Resistant Element (TRE) on the device’s SOC. Unlike a separate processor, it consumes less power and can be activated wirelessly using a secure industry-accepted protocol, eliminating the need for specific SIM hardware.

🔌 How Does System-on-a-Chip (SOC) Work? ðŸ”Œ

To understand iSIM, let’s delve into the concept of integrating with the device’s SOC more deeply. An IoT device often needs to perform various tasks, such as connecting to WiFi, processing audio and visuals, and sending/receiving data. Incorporating the SIM directly into the SOC reduces costs, simplifies manufacturing, and minimizes power consumption for battery-powered devices. This integration also saves space on the printed circuit board (PCB) and reduces overall costs for enterprises and device manufacturers.

✨ What are the Benefits of iSIM? âœ¨

iSIM offers numerous advantages over traditional SIM technologies:

1️⃣ Size: iSIMs are incredibly small – under 1 millimeter squared – making them the smallest SIM technology available. This compact size allows device manufacturers to add more components or create smaller and more affordable devices.

2️⃣ Security: iSIM specifications adhere to the trusted standards of the Trust Connectivity Alliance. Integrated into the SOC’s secure enclave, iSIMs are highly resistant to tampering, theft, or damage. Their fixed integration makes it harder for unauthorized access.

3️⃣ Resources: iSIM technology is a significant leap forward in terms of power consumption and cost. By configuring iSIMs to reduce standby power, it provides an efficient alternative to multi-chip approaches like eSIM. Fewer components and simplified design also reduce manufacturing and logistical costs.

4️⃣ Compatibility: iSIMs can seamlessly connect to 2G, 3G, 4G, and 5G networks and are not tied to any specific network requirement. Standardized by GSMA, 3GPP, ETSI, and other global organizations, iSIMs enable devices to switch networks Over-The-Air (OTA) based on location, cost, or preference.

5️⃣ Use Cases: Due to their small size and wide compatibility, iSIMs open up endless possibilities for enterprises and device manufacturers to explore innovative business models. They can be used in applications like utilities for electricity or gas meters, medical equipment and wearables, logistics use cases, vehicle telematics systems, and more.
