Short Message/Messaging Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile devices exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines.
An emergency telephone number is a number that allows a caller to contact local emergency services for assistance. The emergency number differs from country to country; it is typically a three-digit number so that it can be easily remembered and dialed quickly. Some countries have a different emergency number for each of the different emergency services; these often differ only by the last digit.
Unstructured Supplementary Service Data (USSD), sometimes referred to as "quick codes" or "feature codes", is a communications protocol used by GSM cellular telephones to communicate with the mobile network operator's computers. USSD can be used for WAP browsing, prepaid callback service, mobile-money services, location-based content services, menu-based information services, and as part of configuring the phone on the network. The service does not require a messaging app, and does not incur charges.
A mobile phone feature is a capability, service, or application that a mobile phone offers to its users. Mobile phones are often referred to as feature phones, and offer basic telephony. Handsets with more advanced computing ability through the use of native code try to differentiate their own products by implementing additional functions to make them more attractive to consumers. This has led to great innovation in mobile phone development over the past 20 years.
Mobile malware is malicious software that targets mobile phones or wireless-enabled Personal digital assistants (PDA), by causing the collapse of the system and loss or leakage of confidential information. As wireless phones and PDA networks have become more and more common and have grown in complexity, it has become increasingly difficult to ensure their safety and security against electronic attacks in the form of viruses or other malware.
000 Emergency, also known as Triple Zero or Triple 0, and sometimes stylised Triple Zero (000), is the primary national emergency telephone number in Australia and Australian External Territories. The Emergency Call Service is operated by Telstra, and overseen by the Australian Communications and Media Authority (ACMA), and is intended only for use in life-threatening or time-critical emergencies.
Wi-Fi calling refers to mobile phone voice calls and data that are made over IP networks using Wi-Fi, instead of the cell towers provided by cellular networks. Using this feature, compatible handsets are able to route regular cellular calls through a wireless LAN (Wi-Fi) network with broadband Internet, while seamlessly change connections between the two where necessary. This feature makes use of the Generic Access Network (GAN) protocol, also known as Unlicensed Mobile Access (UMA).
Mobile advertising is a form of advertising via mobile (wireless) phones or other mobile devices. It is a subset of mobile marketing, mobile advertising can take place as text ads via SMS, or banner advertisements that appear embedded in a mobile web site.
Mobile device management (MDM) is the administration of mobile devices, such as smartphones, tablet computers, and laptops. MDM is usually implemented with the use of a third-party product that has management features for particular vendors of mobile devices. Though closely related to Enterprise Mobility Management and Unified Endpoint Management, MDM differs slightly from both: unlike MDM, EMM includes mobile information management, BYOD, mobile application management and mobile content management, whereas UEM provides device management for endpoints like desktops, printers, IoT devices, and wearables as well.
The Samsung SCH-u470, or Juke and Verizon Wireless Juke, is a mobile phone offered exclusively by Verizon Wireless. It was announced on 2 October 2007, and released that same year on Q4 in three colors: red, teal, and navy (blue). The phone is a music player when closed, and can be swiveled for use of the mobile phone. It also has a VGA-resolution camera with a special "night shot" mode for taking photos in low-light conditions.
A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light-weight laptops, and the hybridization of the two in 2-in-1 PCs.
The HTC Dream is a smartphone developed by HTC. First released in September 2008 for $179 with a 2-year contract to T-Mobile, the Dream was the first commercially released device to use the Linux-based Android operating system, which was purchased and further developed by Google and the Open Handset Alliance to create an open competitor to other major smartphone platforms of the time, such as Symbian, BlackBerry OS, and iPhone OS. The operating system offers a customizable graphical user interface, integration with Google services such as Gmail, a notification system that shows a list of recent messages pushed from apps, and Android Market for downloading additional apps.
A mobile phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and therefore mobile telephones are called cellphones in North America. In addition to telephony, digital mobile phones support a variety of other services, such as text messaging, multimedia messaging, email, Internet access, short-range wireless communications, satellite access, business applications, payments, multimedia playback and streaming, digital photography, and video games. Mobile phones offering only basic capabilities are known as feature phones ; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones.

Carrier IQ was a privately owned mobile software company founded in 2005 in Sunnyvale, California. It provided diagnostic analysis of smartphones to the wireless industry via the installation of software on the user's phone, typically in a manner that cannot be removed without rooting the phone. The company says that its software is deployed in over 150 million devices worldwide.
Phone Link, previously Your Phone, is a syncing software developed by Microsoft to connect Windows PCs to Android and iOS mobile devices to view notifications, make phone calls, use mobile apps amongst others, via the PC. It is a native component of Windows 10 and Windows 11, where it is a UWP app and consists of a driver that communicates with the mobile device, where it is named the Link to Windows app. Phone Link makes use of Wi-Fi, Bluetooth for voice calls, or mobile data; it syncs via Microsoft servers, meaning that an internet connection is required.
Google Messages is a text messaging software application developed by Google for its Android and Wear OS mobile operating systems, while it's also available via the Web.
Next Generation 112 (NG112) is a blueprint for emergency communications which are entirely based on Internet Protocol (IP) technology, from the citizen requesting help to the Public Safety Answering Point (PSAP) responding to that request. Over the last decade or so, publicly available electronic communications network providers have started their respective journeys toward migrating to Next-generation networks. Network rollouts are more advanced in some countries than others but by the end of the 2020s, networks will be predominantly IP-based providing a platform for innovative multimedia communications. In mobile networks this will be based on 4G and 5G technology and most voice communications will be based on Session Initiation Protocol (SIP). Public authorities need to respond to these developments so that PSAPs are equipped to receive emergency communications originating on many different types of devices and applications. NG112 provides the basis for this as a flexible, scalable and future-proofed platform for emergency communications.
