Twilio Changelog

Additions and changes to the Twilio platform

Twilio Super SIM® is available for download as an eSIM profile. Until now Super SIMs were available as physical SIMs in various form factors (2FF/3FF/4FF and MFF2). With the eSIM support, you can now reserve a SIM profile via a new API and then download the reserved SIM profile from Twilio’s SM-DP+ server to your eSIM/eUICC-enabled IoT device. Here is the typical call flow that you will use for downloading a Super SIM profile:

Typical call flow for downloading a Super SIM Profile

Twilio currently supports Consumer Profile eUICC SIMs. In order to download a Super SIM profile, your device must have a Consumer Profile eUICC SIM (in any form factor) and the Local Profiles Assistant (LPA) software on the device. Please see Consumer Profile eSIMs for IoT devices for more details on device requirements. 

If you are interested in trying out Super SIM profiles or reviewing our API documentation, please sign up for the pilot.
