The growth in popularity has been rapid in some places; for example, in the UK, the total number of mobile phones overtook the number of houses in 1999. Mobile phones are considered an important human invention as they have been one of the most widely used and sold pieces of consumer technology. For feature phones as of 2016update, the top-selling brands were Samsung, Nokia and Alcatel. The first handheld mobile phone was demonstrated by Martin Cooper of Motorola in New York City on 3 April 1973, using a handset weighing c.

A major breakthrough came in 1973, when the first handheld cellular mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola, using a handset weighing 2 kilograms (4.4 lb). Early mobile phones required vehicle installation due to their size and power needs. The advances in mobile telephony have been traced in successive „generations“, starting with the early zeroth-generation (0G) services, such as Bell System’s Mobile Telephone Service and its successor, the Improved Mobile Telephone Service. Early predecessors of cellular phones included analog radio communications from ships and trains. A handheld mobile radio telephone service was envisioned in the early stages of radio engineering. „Mobile phone“ is the most common English-language term, while the term „cell phone“ is in more common use in North America – both are in essence shorter versions of „mobile telephone“ and „cellular telephone“, respectively.
Capacity was further increased when phone companies implemented digital networks. Due to bandwidth limitations each cell will have a maximum number of cell phones it can handle at once. The cell towers are usually interconnected to each other and the phone network and the internet by wired connections. In the earliest mobile phone systems by contrast, all control was done manually; the customer would search for an unoccupied channel and speak to a mobile operator to request connection of a call to a landline number or another mobile. The critical advantage that modern cellular networks have over predecessor systems is the concept of frequency reuse allowing many simultaneous telephone conversations in a given service area. Feature phones and basic mobile phones tend to use a proprietary, custom-designed software and user interface.

Feature phones typically provide voice calling and text messaging functionality, in addition to basic multimedia and Internet capabilities, and other services offered by the user’s wireless service provider. Feature phone is a term typically used as a retronym to describe mobile phones which are limited in capabilities in contrast to a modern smartphone. Consequently, the industry began looking to data-optimized fourth-generation (4G) technologies, with the promise of speed improvements up to tenfold over existing 3G technologies. By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth-intensive applications, such as streaming media. Cooper made the first ever call on a cell phone when he called Joel S. Engel, a rival of his who worked for AT&T, saying, „I’m calling you on a cell phone, but a real cell phone, a personal, handheld, portable cell phone.“

Feature phones have basic software platforms whilst smartphones have a fully-featured operating system (commonly abbreviated to an OS), with the two most-used platforms being Android and iOS. SIM and R-UIM cards may be mixed together to allow both GSM and CDMA networks to be accessed. A hybrid mobile phone can hold up to four SIM cards, with a phone having a different device identifier for each SIM Card. The SIM card allows users to change phones by simply removing the SIM card from one mobile phone and inserting it into another mobile phone or broadband telephony device, provided that this is not prevented by a SIM lock. The SIM card is approximately the size of a small postage stamp and is usually placed underneath the battery in the rear of the unit. Most modern mobile phones use lithium-ion (Li-ion) batteries, which are designed to endure between 500 and 2,500 charge cycles.

Many states in the United States have banned texting on cell phones while driving. A study conducted by the University of Vienna examined approaches for reducing inappropriate and problematic use of mobile phones, such as using mobile phones while driving. In 2013, a national survey in the US reported the number of drivers who reported using their cellphones to access the Internet while driving had risen to nearly one of four. This can lead to drivers being stopped for using their device illegally for a phone call when, in fact, they were using the device legally, for example, when using the phone’s incorporated controls for car stereo, GPS or satnav. This is more apparent in countries which ban both handheld and hands-free usage, rather than those which ban handheld use only, as officials cannot easily tell which function of the mobile phone is being used simply by looking at the driver.
