The Twilio company has developed a feature called "Network Access Profiles" into their Super SIM product, which allows device makers to control and manage network access for low-powered, inexpensive IoT devices deployed globally. This feature enables device makers to create customized profiles that restrict access to specific networks or frequency bands, optimizing performance, cost, and coverage. The profiles work by cascading rules from global settings to local network-specific rules, allowing for fine-grained control over network access. With Network Access Profiles, Twilio aims to provide a more flexible and efficient solution for IoT device makers, enabling them to build reliable and resilient solutions that can adapt to changing network conditions.
