EUICC
eUICC (embedded UICC) refers to the architectural standards published by the GSM Association (GSMA) 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 A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless network, wireless and the network is distributed over land areas called ''cells'', each served by at least one fixed-locatio ... service providers to uniquely identify and securely connect to mobile network devices. Applications of eUICC are found in mobile network devices (cell phones, tablets, portable computers, security controllers, medical devices, etc.) that use GSM cellular network eSIM technology. Standards The core standards that define eUICC are published by the GSM Association in two topical areas. Consumer and IOT Core standards for implementing eSIM on mobil ...

ESIM
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. eSIM technology has been referred to as a disruptive innovation for the mobile telephony industry. Most flagship devices manufactured since 2018 that are not SIM locked support eSIM technology; as of October 2023, there were 134 models of mobile phones that supported eSIMs. In addition to mobile phones, tablet computers, and smartwatches, eSIM technology is used for Internet of things applications such as connected cars (smart rearview mirrors, on-board diagnostics, vehicle Wi-Fi hotspots), artificial intelligence translators, MiFi devices, smart earphones, smart metering, GPS tracking units, database transaction units, bicycle-sharing s ...

SIM Card
A typical SIM card (mini-SIM with micro-SIM cutout)A SIM card or SIM (subscriber identity module) 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, tablets, and laptops). SIMs are also able to store address book contacts information, and may be protected using a PIN code to prevent unauthorized use. SIMs are always used on GSM phones; for CDMA phones, they are needed only for LTE-capable handsets. SIM cards are also used in various satellite phones, smart watches, computers, or cameras. The first SIM cards were the size of credit and bank cards; sizes were reduced several times over the years, usually keeping electrical contacts the same, to fit smaller-sized devices. SIMs are transferable between different mobile devices by removing the card itself. Technically, the actual physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A 25 × 15 mm smart card">Vodafone New Zealand SIM card The universal integrated circuit card (UICC) is the physical smart card (integrated circuit card) used in mobile terminals in 2G (Global System for Mobile Communications, GSM), 3G (Universal Mobile Telecommunications System, UMTS), 4G (LTE (telecommunication), LTE), and 5G networks. The UICC ensures the integrity and security of all kinds of personal data, and it typically holds a few hundred kilobytes. The official definition for UICC is found in ETSI TR 102 216, where it is defined as a "smart card that conforms to the specificat ...

GSM Association
The GSM Association (GSMA) is a non-profit trade association that represents the interests of mobile network operators worldwide. More than 750 mobile operators are full GSMA members and a further 400 companies in the broader mobile ecosystem are associate members. History The GSMA was formed in 1995 as the GSM MoU Association as a body to support and promote mobile operators using the GSM (Global System for Mobile communications) standard for cellular networks. It traces its history back to a memorandum of understanding signed in 1987 by 13 operators in 12 countries that committed to deploying GSM for mobile services. Membership and governance Full membership of the GSMA is open to licensed mobile operators using a GSM family technology. Approximately 750 such operators around the world are full GSMA members. Associate membership of the GSMA is open to non-operator companies active in the mobile ecosystem. These include handset and device makers, software companies, equi ...

Cellular Network
A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless network, wireless and the network is distributed over land areas called ''cells'', each served by at least one fixed-location transceiver (such as a base station). These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content via radio waves. Each cell's coverage area is determined by factors such as the power of the transceiver, the terrain, and the frequency band being used. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell. When joined together, these cells provide radio coverage over a wide geographic area. This enables numerous Mobile device, devices, including mobile phones, Tablet computer, tablets, laptops equipped with mobile broadband modems, and Wearable technology, wea ...
