Esim Go Reference
This Go eSIM module processes eUICC IDentifier (EID) used in the context of Remote Provisioning and Management of the eUICC (eSIM) in according to GSM Association Official Document SGP.02 (Remote Provisioning of Embedded UICC Technical Specification) and SGP.22 (RSP Technical Specification) for EID using the ITU-T E.118 (ITU-T Recommendation E.118, the international telecommunication charge card) based scheme. See GSMA eSIM specifications for more info. Mobile devices that support eSIM include Apple iPhone 12 Pro Max, Samsung Galaxy S20 Ultra, Huawei P40 Pro, Google Pixel 4 XL etc.
