Companies that want to manufacture eUICCs need to obtain SAS-UP (SAS for UICC Production) accreditation for their site. On the other hand, those wanting to perform remote provisioning or download required profiles to eUICCs need to obtain SAS-SM (SAS for Subscription Management) accreditation for their site. The GSMA SAS-UP standard defines a comprehensive set of protocols and security measures for securely handling production data, including certificate management, data generation, and data personalization for Smart Cards (SC) and eUICC-sensitive products.
