By contrast, smartphones generally use a mobile operating system that often shares common traits across devices. 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. 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.
In Japanese mobile phone culture for example, mobile phones are often decorated with charms. Mobile phones are considered an important human invention as it has been one of the most widely used and sold pieces of consumer technology. A study by the London School of Economics found that banning mobile phones in schools could increase pupils’ academic performance, providing benefits equal to one extra week of schooling per year. 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.
The Motorola Razr V3 and LG Chocolate are two examples of devices that were popular for being fashionable while not necessarily focusing on the original purpose of mobile phones, i.e. a device to provide mobile telephony. Screen time, the amount of time using a device with a screen, has become an issue for mobile phones since the adaptation of smartphones. 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.
In March 2011, a US insurance company, State Farm Insurance, announced the results of a study which showed 19% of drivers surveyed accessed the Internet on a smartphone while driving. In September 2010, the US National Highway Traffic Safety Administration (NHTSA) reported that 995 people were killed by drivers distracted by cell phones. Mobile phone use while driving, including talking on the phone, texting, or operating other phone features, is common but controversial. Restrictions on the use of mobile phones are applied in a number of different contexts, often with the goal of health, safety, security or proper functioning of an establishment, or as a matter of etiquette. 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.
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 jokertipp 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 first SIM card was made in 1991 by Munich smart card maker Giesecke & Devrient for the Finnish wireless network operator Radiolinja.citation needed
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. 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.
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. In addition, they enable multimedia playback and streaming, including video content, as well as radio and television streaming. Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as ‘cell phones’ in North America.

The term “5G” was originally used in research papers and projects to denote the next major phase in mobile telecommunication standards beyond the 4G/IMT-Advanced standards. The first publicly available LTE service was launched in Scandinavia by TeliaSonera in 2009. 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. This ensures it can be applied to mobile Internet access, VoIP, video calls, and sending large e-mail messages, as well as watching videos, typically in standard-definition quality. This was followed by 3.5G or 3G+ enhancements based on the high-speed packet access (HSPA) family, allowing UMTS networks to have higher data transfer speeds and capacity.
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. Due to the increasing complexity of mobile phones, they are often more like mobile computers in their available uses.
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. The petition is part of a joint effort by New York Attorney General Eric Schneiderman and San Francisco District Attorney George Gascón and was directed to the CEOs of the major smartphone manufacturers and telecommunication carriers.
