The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP, UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators.
Integrated Digital Enhanced Network (iDEN) is a mobile telecommunications technology, developed by Motorola, which provides its users the benefits of a trunked radio and a cellular telephone. It was called the first mobile social network by many technology industry analysts. iDEN places more users in a given spectral space, compared to analog cellular and two-way radio systems, by using speech compression and time-division multiple access (TDMA).
A SIM card is an integrated circuit (IC) intended to securely store the international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephony devices. Technically the actual physical card is known as a universal integrated circuit card (UICC); this smart card is usually made of PVC with embedded contacts and semiconductors, with the SIM as its primary component. In practice the term "SIM card" refers to the entire unit and not simply the IC.
A SIM lock, simlock, network lock, carrier lock or (master) subsidy lock is a technical restriction built into GSM and CDMA mobile phones by mobile phone manufacturers for use by service providers to restrict the use of these phones to specific countries and/or networks. This is in contrast to a phone that does not impose any SIM restrictions.
The Motorola Razr is a discontinued series of flip phones that is part of the 4LTR line and was manufactured by Motorola Mobility until 2007, in favor of the Motorola Razr2. The V3 was the first phone shown in the series and was introduced in December 2003 and released in the market in the third quarter of 2004. The V3 model was followed soon thereafter by the improved V3i, including a collaboration with Apple Inc. for iTunes to be built-in. It was launched in 2006.
Pantech Inc. is a South Korean company that manufactures mobile phones. Established in 1991, its market is mainly domestic with partners in the United States, Japan, China, Europe and Vietnam. In 2012 Pantech was the second best-selling handset maker in South Korea, according to Gartner. In 2013 Samsung Electronics bought a 10% stake in Pantech. Pantech also partners with PCD for specialized phones.
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.
The Motorola StarTAC, first released on January 3, 1996, is often assumed to be the first ever clamshell (flip) mobile phone. Technically, however, NEC had been releasing flip phones on NTT Docomo's PDC Mova network long before 1996, namely the TZ-804 and TZ-1501, both respectively launched in 1991 and late 1994. Another early precursor of this form factor was the Grillo, which was designed in Italy by Richard Sapper and Marco Zanuso in 1965. The StarTAC is the successor of the MicroTAC, a semi-clamshell design first launched in 1989. Whereas the MicroTAC's flip folded down from below the keypad, the StarTAC folded up from above the display. In 2005, PC World named the StarTAC as the 6th Greatest Gadget of the Past 50 Years. The StarTAC was among the first mobile phones to gain widespread consumer adoption; approximately 60 million StarTACs were sold.
Some mobile phones support use of two SIM cards, described as dual SIM operation. When a second SIM card is installed, the phone may allow users to switch between two separate mobile network services manually, have hardware support for keeping both connections in a "standby" state for automatic switching, or have two transceivers to maintain both network connections at once.
Dual-mode mobiles refer to mobile phones that are compatible with more than one form of data transmission or network.

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, video games and digital photography. Mobile phones offering only basic capabilities are known as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones.
The HTC Touch Pro2 is a slate smartphone, part of the Touch series of Internet-enabled, Windows Mobile, Pocket PC smartphones designed and marketed by HTC Corporation of Taiwan.
