It’s a SIM card with eUICC Technology (embedded Universal Integrated Circuit Card) called eSIM. eSIM gives you the ability to remotely programme the SIM and provision different Mobile Network Operators on the SIM. You can swap MNOs on the fly and connect to a Local MNO in any country in the world.
‘IMSI’ Stands for International Mobile Subscriber Identity. This is a unique identifier number used by the Mobile Network Operators (MNOs) to identify the Subscribers and it’s key component of the Subscriber Identity Module (SIM) profile.
eUICC stands for – Embedded Universal Integrated Circuit Card. It is the software layer of the eSIM. It provides a remote SIM provisioning functionality. You can store multiple carrier operator profiles on the SIM. IoT devices can now provision and manage their mobile connectivity Over the Air. (OTA)
The eUICC Identifier (EID) is a unique global identifier for eUICC SIMs and its length is 32 digits. The EID is a 32-digit number, containing information that identifies the SIM supplier as well as acting as a global unique identifier for the physical SIM.
A multi-IMSI SIM contains Multiple IMSIs, each IMSI hosts a different (MNO) Mobile Network Operator, The SIM can Provide regional and local MNOs providing local access in any country in the world. If you are to use a single IMSI SIM, you’re stuck with their roaming partners and causes network coverage issues.
A consumer SIM is locked into one network from your local country and has high roaming costs, with fixed data volumes. An IoT SIM has Multiple (MNOs) Mobile Network Operators on the SIM, with the flexibility to remotely provision (RSP) or swap MNOs on the fly and design your Global network coverage to provide better local access and price. An IoT SIM has a PaY-As-You-Go model, perfect for enterprise customers.
An ICCID (Integrated Circuit Card Identifier ID) is a unique 19- or 20-digit number assigned to a SIM card. It is used to identify the SIM internationally and is typically printed on the SIM card itself and stored inside its memory. It’s the Identifier of the SIM card, UICC card, and profile.
EID (eUICC Identifier) is a unique 32-digit number assigned to an eUICC (Embedded Universal Integrated Circuit Card), commonly found in eSIMs. It serves as a global identifier for the eSIM and is essential for remote SIM provisioning and management. A device with an eSIM capability has an EID. an iPhone for example.
