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.
Today, mobile phones are globally ubiquitous, and in almost half the world’s countries, over 90% of the world population, or approximately 7.2 billion people, owns at least one. 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). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as ‘cell phones’ in North America.
Mobile phones are considered an important human invention as it has been one of the most widely used and sold pieces of consumer technology. In most jurisdictions, prison inmates are forbidden from possessing mobile phones due to their ability to communicate with the outside world and other security issues. Other countries, such as China and the Netherlands, have introduced special lanes for smartphone users to help direct and manage them. Many passengers are pressing airlines and their governments to allow and deregulate mobile phone use, while some airlines, under the pressure of competition, are also pushing for deregulation or seeking new technology which could solve the present problems. In the U.S., the Federal Communications Commission (FCC) regulations prohibit the use of mobile phones aboard aircraft in flight.

From data to durians: H2O.ai’s journey to AI-led accessibility
In Israel, similar phones to kosher phones with restricted features exist to observe the sabbath; under Orthodox Judaism, the use of any electrical device is generally prohibited during this time, other than to save lives, or reduce the risk of death or similar needs. Demand for metals used in mobile phones and other electronics fuelled the Second Congo War, which claimed almost 5.5 million lives. Even so, mobile phones typically have less value on the second-hand market if the phones original IMEI is blacklisted. Studies have shown that around 40–50% of the environmental impact of mobile phones occurs during the manufacture of their printed wiring boards and integrated circuits. China has proposed using this technology to track the commuting patterns of Beijing city residents. Enabling contactless payments through NFC-equipped mobile phones requires the co-operation of manufacturers, network operators, and retail merchants.

Depending on the device’s type and design, the screen fills most or nearly all of the space on a device’s front surface. Mobile CPU performance depends not only on the clock rate (generally given in multiples of hertz) but also the memory hierarchy also greatly affects overall performance. Mobile processors commonly use heterogeneous multicore architectures, combining cores with different performance and power characteristics so betsomnia that computational workloads can be distributed according to their processing requirements and energy constraints. With smartphones, NAND flash memory was adopted as it has larger storage capacities and lower costs, but causes longer boot times because instructions cannot be executed from it directly, and must be copied to RAM memory first before execution. The first GSM phones and many feature phones had NOR flash memory, from which processor instructions could be executed directly in an execute in place architecture and allowed for short boot times. Additionally, short-range Wi-Fi infrastructure is often used by smartphones as much as possible as it offloads traffic from cell networks on to local area networks.

This has introduced additional difficulties for law enforcement officials when attempting to distinguish one usage from another in drivers using their devices. In other countries, including the UK and France and in many US states, only handheld phone use is banned while hands-free use is permitted. Although these phones are intended to prevent immodesty, some vendors report good sales to adults who prefer the simplicity of the devices; other Orthodox Jews question the need for them. In the UK and US, law enforcement and intelligence services use mobile phones to perform surveillance operations. Some mobile phones can make mobile payments via direct mobile billing schemes, or through contactless payments if the phone and the point of sale support near field communication (NFC).
- A mobile phone or cell phone is a portable wireless 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).
- The introduction of Apple’s App Store for the iPhone and iPod Touch in July 2008 popularized manufacturer-hosted online distribution for third-party applications (software and computer programs) focused on a single platform.
- 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.
- 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.”

Smartphones are defined by their advanced computing capabilities, which include internet connectivity and access to a wide range of applications. These first-generation (1G) systems could support far more simultaneous calls but still used analog cellular technology. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. Furthermore, mobile phones offer satellite-based services, such as navigation and messaging, as well as business applications and payment solutions (via scanning QR codes or near-field communication (NFC)). In addition, they enable multimedia playback and streaming, including video content, as well as radio and television streaming. Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recording, and gaming.
The introduction of Apple’s App Store for the iPhone and iPod Touch in July 2008 popularized manufacturer-hosted online distribution for third-party applications (software and computer programs) focused on a single platform. The first mobile news service, delivered via SMS, was launched in Finland in 2000, and subsequently many organizations provided “on-demand” and “instant” news services by SMS. A mobile app is a computer program designed to run on a mobile device, such as a smartphone. Of the two, Android has been the best-selling system worldwide on smartphones since 2011, and as of March 2025, Android had 71.9% of the overall market share, while iOS had 27.7%.
