Embedded-SIM/embedded universal integrated circuit card (eUICC) – Electronic SIM profile
eUICC can be implemented in MFF2 chips or in plastic SIM cards. eSIM solution follows a new GSMA standard, that allows electronic profile delivery over the air (OTA). Top Connect provides turn-key eSIM solutions (SMDP/SMSR/OTA) for partners willing to develop a product based on this new and very effective technology.
