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.
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 ...
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.
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.
Change in applications and menus stored on the SIM is difficult after the customer takes delivery of the SIM and sometimes may be recognized as surveillance software. To deliver updates, either the SIM must be returned and exchanged for a new one (which can be costly and inconvenient) or the application updates must be delivered over-the-air ...
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?].
Matter is a freely available connectivity standard for smart home and IoT (Internet of Things) devices. [2] [3] [4] It aims to improve interoperability and compatibility between different manufacturers and security, and always allowing local control as an option.
SVN: 23 - The "software version number" identifying the revision of the software installed on the phone. 99 is reserved. By contrast, the new style IMEI code 49-015420-323751-8 has an 8-digit TAC of 49-015420. The CDMA Mobile Equipment Identifier uses the same basic format as the IMEI but gives more flexibility in allocation sizes and usage.
