Root Discovery Service

The GSMA Root Discovery Service is an integral part of the GSMA Remote SIM Technical Specification and Architecture, SGP.21 and SGP.22, acting as a one stop shop for profile acquisition.  As a globally available Internet service the Discovery Service acts as a central communication point for eSIM-enabled consumer devices, allowing the consumer to acquire their profiles on demand.

The DS is designed to be the most efficient means of profile acquisition, more efficient than other methods, such as activation codes or primary device pre-loading, with minimum end user interaction required.

How it Works for the end user

The Discovery Server is available to enable end users, with an agreed mobile subscription contract, to connect their device with their subscribed profile.

Once they have agreed a mobile subscription contract with an operator, the end user can retrieve the corresponding profile onto their device directly from the Discovery Service.

How it works for the profile owner

Connection of an Operator’s SM-DP+ (or Alternative SM-DS) to the GSMA Root Discovery Service requires interoperability testing, followed by contract agreement and payment for the discovery service.

Interoperability testing

Interoperability testing is mandatory for SM-DP+ (or Alternative SM-DS) wishing to use the GSMA Root DS service.  This ensures interoperability and integrity of the system.  Interoperability testing must be performed via the GSMA Root DS Customer Test Environment (CTE).

GSMA test certificates to perform interoperability testing are available from the GSMA Certificate Issuer. Use of the CTE is free of charge, as are the test certificates.

To apply, download and complete the DSA.6 form and email to dsrootenquiries@gsma.com

How it works for the Device/LPA/eUICC

Access to the DS server is via a fair-use policy. Device and eUICC manufactures wishing to ensure connection of their devices to the DS are recommended to conduct interoperability testing using the GSMA DS Customer Test Environment (CTE).
