Developers of wireless-enabled industrial devices are frequently faced with a specific design challenge: the SIM (Subscriber Identity Module) card.
This essential part of the M2M wireless value chain was originally designed for consumer mobile phones. However, whereas the average mobile phone user upgrades the handset every 18-24 months, industrial wireless M2M devices need to stay online for 5, 10 or 15 years, sometimes even longer. M2M products must also be able to meet extreme environmental conditions of shock, corrosion, temperature, vibration and humidity.
The Sierra Wireless Embedded SIM provides the solution:
Temperature, vibration and humidity: Our Embedded SIM operates in extreme temperatures, from -40°C to +85°C.
Service provider choice: Use your preferred service provider or carrier, ask Sierra Wireless to recommend one, or take advantage of our existing carrier partnerships.
Subscription portability and security: An integrated switch allows you to switch from the embedded SIM to an external SIM as required.
Size: The size of embedded SIM-enabled modules or modems does not change, and embedded SIM eliminates the need for a SIM card holder and a plastic SIM.
Simplified logistics: Embedded SIM eliminates or reduces the logistics challenges represented by physical SIM cards, such as inventory management, secure storage and activation.
