This database of laws provides a comprehensive view of the provisions of laws that restrict the use of mobile communication devices while driving for all 50 states and the District of Columbia between 1992 when first law was passed, through 1 December 2010. Japan prohibits all mobile phone use while driving, including use of hands-free devices. In many countries, mobile phones are used to provide mobile banking services, which may include the ability to transfer cash payments by secure SMS text message.
Mobile phones are considered an important human invention as it has been one of the most widely used and sold pieces of consumer technology. They also stated that with the lack of data for the research and the usage periods of 15 years will warrant further research for smartphones and the cause of brain tumors. 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.
- Screen sizes are often measured in diagonal inches or millimeters; feature phones generally have screen sizes below 90 millimetres (3.5 in).
- 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.
- 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.
- Up until that point, smartphone application distribution depended on third-party sources providing applications for multiple platforms, such as GetJar, Handango, Handmark, and PocketGear.
- 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%.
- 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.
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. In developed countries, smartphones have largely replaced earlier mobile technologies, while in developing regions, they account for around 50% of all mobile phone usage. 3G is able to provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. These first-generation (1G) systems could support far more simultaneous calls but still used analog cellular technology. Early predecessors of cellular phones included analog radio communications from ships and trains.
Screen sizes are often measured in diagonal inches or millimeters; feature phones generally have screen sizes below 90 millimetres (3.5 in). 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 that computational workloads can be distributed according to their processing requirements and energy constraints.
A common data application on mobile phones is Short Message Service (SMS) text messaging. 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%. 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.

Contrary to popular misconception, the Federal Aviation Administration (FAA) does not actually prohibit the use of personal electronic devices (including cell phones) on aircraft. Mobile phone technology has progressed significantly since its origins, evolving from large car-mounted systems to compact, handheld devices. Furthermore, mobile phones offer satellite-based services, such as navigation and messaging, as well as business applications and payment solutions (via scanning megawaysvip QR codes or near-field communication (NFC)).

These 0G systems were not cellular, supported a few simultaneous calls, and were very expensive. 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. 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.
- 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.
- In 2001, the third-generation (3G) was launched in Japan by NTT DoCoMo on the WCDMA standard.
- 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.
- 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.
- 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.
Because of these problems, the performance of mobile phone CPUs is often more appropriately given by scores derived from various standardized tests to measure the real effective performance in commonly used applications. Handsets with more advanced computing ability through the use of native software applications are known as smartphones. Low-end mobile phones are often referred to as feature phones and offer basic telephony. The automation systems can control the “hand off” of a customer handset moving between one cell and another so that a call in progress continues without interruption, changing channels if required. Former systems would cover a service area with one or two powerful base stations with a range of up to tens of kilometers’ (miles), using only a few sets of radio channels (frequencies).
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 phone is a term typically used as a retronym to describe mobile phones which are limited in capabilities in contrast to a modern smartphone. The International Telecommunication Union measures those with Internet connection, which it calls Active Mobile-Broadband subscriptions (which includes tablets, etc.).

By contrast, smartphones generally use a mobile operating system that often shares common traits across devices. Smartphones are defined by their advanced computing capabilities, which include internet connectivity and access to a wide range of applications. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries.
