What is the GSMA SGP.31 / SGP.32 specification supported by melita.io?

GSMA SGP.31 / SGP.32 is the IoT focused eSIM technical specification that defines lightweight, secure, and fully remote SIM provisioning and lifecycle management for connected devices without user interaction. Built on the security foundations of SGP.21 / SGP.22 and aligned with the GSMA’s IoT architecture, it enables scalable, lowpower, and globally interoperable eSIM deployments across modern IoT networks. Our approach follows the GSMA’s standardised IoT provisioning model to ensure seamless, interoperable fleet operations.
