To enhance security and control over data transmission for IoT devices connected via Super SIM, Twilio now offers VPN (Virtual Private Network) support. This feature enables secure private networks between Twilio and application data centers, while also providing benefits such as secure channels, private end-to-end networks, extended session durations, and no need for client-based VPNs. However, not all IoT use cases require VPNs, and the additional complexity and cost should be carefully considered. With Super SIM VPN, devices can only communicate with the application cloud, and static IP addresses are assigned to each device, allowing easy access from the cloud. To access Super SIM VPN, users must join the Private Beta phase and follow a step-by-step guide provided by Twilio.
