When eSIM devices are first switched on they need to find the subscriber’s chosen operator to activate cellular connectivity. GSMA eSIM Discovery has been designed to make this process as fast and seamless as possible, requiring minimum action from the end user – it is a digital method for profile activation, which the industry has specified itself.
Established as a globally available cloud-based platform, GSMA eSIM Discovery matches the eSIM, using its eUICC Identifier (EID), with the owners purchased network operator profile. The eSIM device is then able to seamlessly acquire the eSIM profile from the correct operator. Use cases from both consumer and consumer IoT are perfectly suited to benefit from this Discovery (DS) method.
GSMA eSIM Discovery is an integral part of the GSMA Remote SIM Technical Specification and Architecture, SGP.21 eSIM Architecture Specification and SGP.22 eSIM Technical Specification.
