(U)SIM Interface
The (U)SIM interface is the connecting point of the mobile phone and the UICC with its SIM or USIM application. Standardisation of the (U)SIM interface The UICC with the SIM or USIM application plays an important role in mobile telephony as it is the secure element identifying a subscriber in the network and allowing MNOs to bill the respective account. Hence it is crucial to have standardised features e.g. placing phone calls or sending SMS working throughout the global network with all available handsets and (U)SIM cards resp. UICCs. Developing globally applicable standards for communication technologies is the task of standardisation bodies such as ETSI (European Telecommunications Standards Institute, 3GPP (Third Generation Partnership Project) and 3GPP2 The 3rd Generation Partnership Project 2 (3GPP2) was a collaboration between telecommunications associations to make a globally applicable third generation (3G) mobile phone system specification within the scope of the ...

Mobile Phone
A mobile phone or cell phone is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones ( landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. These include text messaging, multimedia messaging, email, and internet access (via LTE, 5G NR or Wi-Fi), as well as short-range wireless technologies like Bluetooth, infrared, and ultra-wideband (UWB). Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subscriber Identity Module
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 physic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mobile Network Operator
A mobile network operator (MNO), also known as a mobile network provider, mobile network carrier, mobile , wireless service provider, wireless carrier, wireless operator, wireless telco, or cellular company, is a telecommunications provider of services that sells, delivers and maintains mobile telephony services to an end user. Overview A key defining characteristic of a mobile network operator is that it must own or control access to a radio spectrum license from a regulatory or government entity, and also that it must own or control the elements of the cellular network infrastructure necessary to provide services to subscribers over the licensed radio spectrum. In addition the operator would also contain other elements like the back haul infrastructure and provisioning computer systems. A mobile network operator typically also has the necessary provisioning, billing, and customer care computer systems, and the marketing, customer care, and engineering organizations need ...
