eUICC (embedded UICC [1]) refers to the architectural standards published by the GSM Association (GSMA) [2] [3] or implementations of those standard for eSIM, a device used to securely store one or more SIM card profiles, which are the unique identifiers and cryptographic keys used by cellular network service providers to uniquely identify and securely connect to mobile network devices.
An eSIM (embedded SIM) is a form of SIM card that is embedded directly into a device as software installed onto a eUICC chip. First released in March 2016, eSIM is a global specification by the GSMA that enables remote SIM provisioning; end-users can change mobile network operators without the need to physically swap a SIM from the device.
GSMA have also developed a compliance framework [9] for eSIM devices, eUICCs, and subscription management products - to help with interoperability and security for products supporting eSIM. This is published by the GSMA as SGP.24, [10] the eSIM compliance process describes common compliance requirements for: Functional interoperability; eUICC ...
Geneva, Switzerland, Dec. 19, 2024 (GLOBE NEWSWIRE) -- SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI and Post-Quantum technology hardware and software products, today announced that its GSMA-accredited eUICC (Embedded Universal Integrated Circuit Card) technology now enables mobile phones and connected devices to ...
In August 2018, the company became the largest manufacturer of SIM with eUICC software production in the Middle East and Africa to be certified by the GSMA. [8] [9] In October 2018, Workz collaborated with Truphone to launch a remote SIM.
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 3rd Generation Partnership Project (3GPP) is an umbrella term for a number of standards organizations which develop protocols for mobile telecommunications.Its best known work is the development and maintenance of: [1]
