Fixed IP ranges for Super SIM traffic Beta

Twilio Mobile Core now uses a set of fixed IP ranges for traffic originating from Super SIM enabled devices. This enables you to set up filters on your firewall to accept traffic only from these IP ranges, instead of accepting traffic from anywhere on the Internet. The following IP address ranges are used

3.239.194.0/27
3.64.1.224/27
13.212.223.64/27

Please refer to the documentation for more details.
