The Universal Integrated Circuit Card (UICC) and its applications and data play a fundamental role in ensuring the connectivity and security of the network, the subscriber’s account and related services and transactions. Based on the existing UICC technology used in today’s removable SIM cards, GSMA has defined a set of Embedded SIM specifications that allows the “over the air” provisioning of an initial operator subscription, and the subsequent change of subscription from one operator to another.
The GSMA’s Embedded SIM Specification provides a single, de-facto standard mechanism for the remote provisioning and management of machine to machine (M2M). GSMA Embedded SIM is a vital enabler for Machine to Machine (M2M) connections including the simple and seamless mobile connection of all types of connected machines. In the M2M market the SIM may not easily be changed via physical access to the device or may be used in an environment that requires a soldered connection, thus there is a need for ‘over the air’ provisioning of the SIM with the same level of security as achieved today with traditional removable SIM.

UICC (Universal Integrated Circuit Card) is the hardware used in mobile devices that contains SIM and/or USIM applications enabling access to GSM, UMTS/3G and LTE networks.
Embedded SIM is a UICC that supports “over the air” provisioning of an initial operator subscription and the subsequent change of subscription from one operator to another in accordance with the GSMA Embedded SIM specification. Use of the GSMA Embedded SIM Specification simplifies industrial and logistic processes for the distribution of M2M equipment.
