eUICC can refer to any implementation or application of the eUICC standards in an eSIM device. Each implementation of eUICC includes software code, a processor to emulate the software, non-volatile memory used to store the unique identifiers and cryptographic keys that are part of a SIM profile, and a bus interface to communicate the SIM profile to the mobile device. eUICC standards specify ...
If the eSIM is eUICC-compatible, it can be re-programmed with new SIM information. Otherwise, the eSIM is programmed with its ICCID/IMSI and other information at the time it is manufactured, and cannot be changed. One common physical form factor of an eUICC chip is commonly designated MFF2. [7]
A UICC consists of a CPU, ROM, RAM, EEPROM and I/O circuits. Early versions consisted of the whole full-size (85 × 54 mm, ISO/IEC 7810 ID-1) smart card. Soon the race for smaller telephones called for a smaller version of the card.
A typical SIM card (mini-SIM with micro-SIM cutout) A SIM (Subscriber Identity Module) card is an integrated circuit (IC) intended to securely store an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephone devices (such as mobile phones and laptops).
The LPA will request carrier profiles available for download, either by submitting the activation code provided by the user or the eSIM ID (EID) of the eUICC. The SM will provide the requested profile encrypted in a way that only the eUICC can decrypt/install to ensure the network authentication key remains secure.
The Single Wire Protocol (SWP) is a specification for a single-wire connection between the SIM card and a near field communication (NFC) chip in a cell phone. It was under final review by the European Telecommunications Standards Institute (ETSI) [when?].
[10] [11] In November, Workz together with Arm offered full eUICC manufacturing and remote SIM based on the Arm technology. [12] In December, the company signed a partnership with MTX Connect, the Luxembourg-based mobile virtual network operator to launch virtual SIMs. [13] [14] In 2019, Workz launched its first 5G SIM card.
