69-570: The Nokia N73 is a mobile phone announced by Nokia on 2006 as part of the Nseries and started shipping on 15 July. The N73 succeeded the N70 and packed in numerous multimedia features. It features a 3.2 megapixel autofocus camera, a front camera, a then-large 2.4-inch display, and stereo speakers, all in a relatively slim and pocketable size and form. It runs on Symbian v9.1 ( S60 3rd Edition). An improved, music-focused version called N73 Music Edition

138-553: A cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication , digital mobile phones have evolved to support a wide range of additional services. 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). Mobile phones also support

207-412: A retronym to describe mobile phones which are limited in capabilities in contrast to a modern smartphone . 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 . A feature phone has additional functions over and above a basic mobile phone, which

276-404: A base station with (for example) a useful range on the order of a kilometer (mile). These systems have dozens or hundreds of possible channels allocated to them. When a subscriber is using a given channel for a telephone connection, that frequency is unavailable for other customers in the local cell and in the adjacent cells. However, cells further away can re-use that channel without interference as

345-408: A channel. It would be impractical to give every customer a unique channel since there would not be enough bandwidth allocated to the mobile service. As well, technical limitations such as antenna efficiency and receiver design limit the range of frequencies a customer unit could use. A cellular network mobile phone system gets its name from dividing the service area into many small cells, each with

414-438: A concern in day-to-day use. Future mobile phone batteries are expected to utilize advanced technologies such as silicon-carbon (Si/C) batteries and solid-state batteries, which promise to offer higher energy densities, longer lifespans, and improved safety compared to current lithium-ion batteries. Mobile phones require a small microchip called a Subscriber Identity Module or SIM card , in order to function. The SIM card

483-540: A different set of frequencies from neighboring cells, and will typically be covered by three towers placed at different locations. The cell towers are usually interconnected to each other and the phone network and the internet by wired connections. Due to bandwidth limitations each cell will have a maximum number of cell phones it can handle at once. The cells are therefore sized depending on the expected usage density, and may be much smaller in cities. In that case much lower transmitter powers are used to avoid broadcasting beyond

552-506: A given service area. This allows efficient use of the limited radio spectrum allocated to mobile services, and lets thousands of subscribers converse at the same time within a given geographic area. 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). Once these few channels were in use by customers, no further customers could be served until another user vacated

621-421: A handset making a call, interface with the land-line side of the network to connect to other subscribers, and collection of billing information for the service. 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. In the earliest mobile phone systems by contrast, all control

690-453: A laptop, desktop, and tablet computers. Recent development in PTT communications is the appearance of apps on smartphones , some of which can function on multiple platforms. Wireless carrier-grade PTT systems have adapted to and adopted the smartphone platform by providing downloadable apps that support their PTT systems across many mobile platforms. Over-the-top (OTT) applications do not depend on

759-515: A mobile device, such as a smartphone. The term "app" is a shortening of the term "software application". A common data application on mobile phones is Short Message Service (SMS) text messaging. The first SMS message was sent from a computer to a mobile phone in 1992 in the UK while the first person-to-person SMS from phone to phone was sent in Finland in 1993. The first mobile news service, delivered via SMS,

828-514: A music player, a Visual FM Radio , RealPlayer , an IM client, a WAP browser, a full web browser based on KHTML / WebKit , a Microsoft Office document viewer, a PDF viewer, an Adobe Flash Lite viewer and some games. The majority of these applications support background execution; for example, one may listen to music while browsing the Internet, and then may switch to write a text message or e-mail, without having to close any applications. With

897-501: A problem due to the design of the phone, the quality of the cellular network and compression algorithms used in long-distance calls . Audio quality can be improved using a VoIP application over WiFi . Cellphones have small speakers so that the user can use a speakerphone feature and talk to a person on the phone without holding it to their ear. The small speakers can also be used to listen to digital audio files of music or speech or watch videos with an audio component, without holding

966-464: A single hand, since most thumbs cannot reach the entire screen surface; they may need to be shifted around in the hand, held in one hand and manipulated by the other, or used in place with both hands. Due to design advances, some modern smartphones with large screen sizes and "edge-to-edge" designs have compact builds that improve their ergonomics, while the shift to taller aspect ratios have resulted in phones that have larger screen sizes whilst maintaining

1035-512: A single platform. There are a huge variety of apps, including video games , music products and business tools. Up until that point, smartphone application distribution depended on third-party sources providing applications for multiple platforms, such as GetJar , Handango , Handmark , and PocketGear . Following the success of the App Store, other smartphone manufacturers launched application stores, such as Google's Android Market (later renamed to

1104-422: A user may be too busy to handle a talk switch, voice operated switches are sometimes employed. Some systems use PTT ID to identify the speaker. Push-to-talk over cellular ( PTToC ) is a service option for a cellular phone network that enables subscribers to use their phones as walkie-talkies with unlimited range. A typical push-to-talk connection connects almost instantly. A significant advantage of PTT

1173-626: A variety of multimedia capabilities, such as digital photography , video recording , and gaming . In addition, they enable multimedia playback and streaming , including video content, as well as radio and television streaming . Furthermore, mobile phones offer satellite-based services, such as navigation and messaging , as well as business applications and payment solutions (via NFC ). Mobile phones offering only basic features are often referred to as feature phones ( slang : "dumbphones" ), while those with advanced computing power are known as smartphones . The first handheld mobile phone

1242-469: A very thin carbon microphone". Early predecessors of cellular phones included analog radio communications from ships and trains. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. 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,

1311-416: A wide range of applications. The International Telecommunication Union measures those with Internet connection, which it calls Active Mobile-Broadband subscriptions (which includes tablets, etc.). In developed countries, smartphones have largely replaced earlier mobile technologies, while in developing regions, they account for around 50% of all mobile phone usage. Feature phone is a term typically used as

1380-400: Is a portable 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 ). This radio frequency link connects to the switching systems of a mobile phone operator , providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on

1449-497: Is approximately the size of a small postage stamp and is usually placed underneath the battery in the rear of the unit. The SIM securely stores the service-subscriber key (IMSI) and the K i used to identify and authenticate the user of the mobile phone. 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

1518-414: Is most commonly located on the radio's handheld microphone, or for small hand-held radios, directly on the radio. For heavy radio users, a PTT foot switch may be used, and also can be combined with either a boom-mounted microphone or a headset with integrated microphone. Less commonly, a separate hand-held PTT switch may be used. This type of switch was historically called a pressel . In situations where

1587-777: Is not available in the Middle East and North Africa. Nokia has also released another model of the N73 called the 'N73 Special Edition' in the Middle East and North Africa. The phone was released during the Muslim holy month of Ramadan in 2007. The phone has the same hardware as the other editions of the N73 but comes pre-loaded with Islamic applications and the phone is completely white. Nokia also released an N73 Special Edition in Indonesia, without pre-loaded Islamic applications. All three versions of

1656-462: Is not being played). In the later firmware versions this application can be terminated, but doing so prevents the Music Edition remote control from working, until the application is started again by using the phone's keypad. The 'N73 Internet Edition' was essentially the Music Edition, but retaining the 'multimedia button' function, rather than a dedicated 'music button'. The 'N73 Internet Edition'

1725-532: Is not prevented by a SIM lock . The first SIM card was made in 1991 by Munich smart card maker Giesecke & Devrient for the Finnish wireless network operator Radiolinja . A hybrid mobile phone can hold up to four SIM cards, with a phone having a different device identifier for each SIM Card. SIM and R-UIM cards may be mixed together to allow both GSM and CDMA networks to be accessed. From 2010 onwards, such phones became popular in emerging markets, and this

1794-626: Is often used by smartphones as much as possible as it offloads traffic from cell networks on to local area networks. The common components found on all mobile phones are: Low-end mobile phones are often referred to as feature phones and offer basic telephony. Handsets with more advanced computing ability through the use of native software applications are known as smartphones . 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. With smartphones, NAND flash memory

1863-459: Is only capable of voice calling and text messaging. Feature phones and basic mobile phones tend to use a proprietary, custom-designed software and user interface . By contrast, smartphones generally use a mobile operating system that often shares common traits across devices. The critical advantage that modern cellular networks have over predecessor systems is the concept of frequency reuse allowing many simultaneous telephone conversations in

1932-800: Is the ability for a single person to reach an active talk group with a single button press; users don't need to make several telephone calls to coordinate with a group. Push-to-talk cellular calls similarly provide half-duplex communications – while one person transmits, the other(s) receive. This combines the operational advantages of PTT with the interference resistance and other virtues of mobile phones. Manufacturers of ( POC or PoC ) hardware include ToooAir and Hytera US Inc. Mobile push-to-talk services, offered by some mobile carriers directly as well as by independent companies, adds PTT functionality to smartphones and specialized mobile handsets (hand portable and mobile/base station PTT Radio Terminals). In addition to mobile handsets, some services also work on

2001-565: The 5G NR (5G New Radio) standard. 5G can be implemented in low-band, mid-band or high-band millimeter-wave, with download speeds that can achieve gigabit-per-second (Gbit/s) range, aiming for a network latency of 1 ms. This near-real-time responsiveness and improved overall data performance are crucial for applications like online gaming , augmented and virtual reality , autonomous vehicles , IoT, and critical communication services. Smartphones are defined by their advanced computing capabilities, which include internet connectivity and access to

2070-627: The Improved Mobile Telephone Service . These 0G systems were not cellular , supported a few simultaneous calls, and were very expensive. The first handheld cellular mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing 2 kilograms (4.4 lb). The first commercial automated cellular network ( 1G ) analog was launched in Japan by Nippon Telegraph and Telephone in 1979. This

2208-645: The WCDMA standard. 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. 3G is able to provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. 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. By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by

2277-450: The internet of things (IoT), fixed wireless access , and multimedia streaming (including music, video, radio , and television ). Deployment of fifth-generation ( 5G ) cellular networks commenced worldwide in 2019. 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 3GPP defines 5G as any system that adheres to

2346-428: The memory hierarchy also greatly affects overall performance. 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. One of the main characteristics of phones is the screen . Depending on the device's type and design, the screen fills most or nearly all of

2415-582: The GSM was used by over 5 billion people in over 220 countries. The GSM (2G) has evolved into 3G, 4G and 5G. The standardization body for GSM started at the CEPT Working Group GSM (Group Special Mobile) in 1982 under the umbrella of CEPT. In 1988, ETSI was established, and all CEPT standardization activities were transferred to ETSI. Working Group GSM became Technical Committee GSM. In 1991, it became Technical Committee SMG (Special Mobile Group) when ETSI tasked

2484-485: The Google Play Store), RIM's BlackBerry App World , or Android-related app stores like Aptoide , Cafe Bazaar , F-Droid , GetJar , and Opera Mobile Store . In February 2014, 93% of mobile developers were targeting smartphones first for mobile app development. As of 2022, the top five manufacturers worldwide were Samsung (21%), Apple (16%), Xiaomi (13%), Oppo (10%), and Vivo (9%). From 1983 to 1998, Motorola

2553-520: The N73 appear to have been updated to the same software as each other. The update on 26 June 2007, updates the standard N73's Music Player to the same version as the Music Edition's enhanced Music Player detailed above, while keeping the 'multimedia button' function, essentially making it an Internet Edition. In 2008, updates with the standard features with Nokia Maps Application installed by default (but requires an external bluetooth GPS receiver), Nokia Lifeblog, PTT , and Search applications carried on from

2622-421: The UK, the total number of mobile phones overtook the number of houses in 1999. Today, mobile phones are globally ubiquitous, and in almost half the world's countries, over 90% of the population owns at least one. A handheld mobile radio telephone service was envisioned in the early stages of radio engineering. In 1917, Finnish inventor Eric Tigerstedt filed a patent for a "pocket-size folding telephone with

2691-572: The ability to transfer cash payments by secure SMS text message. Kenya's M-PESA mobile banking service, for example, allows customers of the mobile phone operator Safaricom to hold cash balances which are recorded on their SIM cards. Cash can be deposited or withdrawn from M-PESA accounts at Safaricom retail outlets located throughout the country and can be transferred electronically from person to person and used to pay bills to companies. Branchless banking has also been successful in South Africa and

2760-961: The benefits of different calling plans. For example, a particular plan might provide for cheaper local calls, long-distance calls, international calls, or roaming. The mobile phone has been used in a variety of diverse contexts in society. For example: In 1998, one of the first examples of distributing and selling media content through the mobile phone was the sale of ringtones by Radiolinja in Finland. Soon afterwards, other media content appeared, such as news, video games, jokes, horoscopes, TV content and advertising. Most early content for mobile phones tended to be copies of legacy media , such as banner advertisements or TV news highlight video clips. Recently, unique content for mobile phones has been emerging, from ringtones and ringback tones to mobisodes , video content that has been produced exclusively for mobile phones. In many countries, mobile phones are used to provide mobile banking services, which may include

2829-462: The case of MP3 audio files, by ID3 tag (e.g. 'album', 'artist', etc.). Notably, Nokia supports firmware upgrades to the N73 to be made by the user via a module in Nokia PC Suite or directly over-the-air. Besides the original edition, Nokia released three other variants of N73. In addition to the basic N73, Nokia subsequently released the N73 'Music Edition' in 2007. The 'multimedia button' on

2898-506: The cell. In order to handle the high traffic, multiple towers can be set up in the same area (using different frequencies). This can be done permanently or temporarily such as at special events or in disasters. Cell phone companies will bring a truck with equipment to host the abnormally high traffic. Capacity was further increased when phone companies implemented digital networks. With digital, one frequency can host multiple simultaneous calls. Additionally, short-range Wi-Fi infrastructure

2967-407: The committee with UMTS (3G). In addition to transmitting voice over digital signals, the 2G network introduced data services for mobile, starting with SMS text messages, then expanding to Multimedia Messaging Service (MMS), and mobile internet with a theoretical maximum transfer speed of 384 kbit/s (48 kB/s). In 2001, the third-generation ( 3G ) was launched in Japan by NTT DoCoMo on

3036-459: The conversation (ICAO doc 9432). In doing so, they are aware of each other's actions and intentions. Unlike in a conference call , they do not hear background noise from the ones who are not speaking. Similar considerations apply to police radio , the use of business band radios on construction sites, and other scenarios requiring coordination of several parties. Citizens Band is another example of classic push-to-talk operation. The PTT switch

3105-496: The end of 2009. In 2014, there were more than seven billion mobile phone subscribers worldwide, a number that is expected to keep growing. Mobile phones are used for a variety of purposes, such as keeping in touch with family members, for conducting business, and in order to have access to a telephone in the event of an emergency. Some people carry more than one mobile phone for different purposes, such as for business and personal use. Multiple SIM cards may be used to take advantage of

3174-531: The ergonomics associated with smaller 16:9 displays. Liquid-crystal displays are the most common; others are IPS , LED , OLED , and AMOLED displays. Some displays are integrated with pressure-sensitive digitizers, such as those developed by Wacom and Samsung , and Apple's " 3D Touch " system. In sound, smartphones and feature phones vary little. Some audio-quality enhancing features, such as Voice over LTE and HD Voice , have appeared and are often available on newer smartphones. Sound quality can remain

3243-408: The exception of the newer Sony Ericsson phones like K550 and W610, feature phones typically cannot do this or can do it in only a very limited way; for example, only the music player can run in the background. Java applications as well as Symbian ( S60 release 3) applications can be installed to or removed from the phone by the user, using either the Nokia PC Suite software, which is included with

3312-486: The first quarter of 2016, the top smartphone developers worldwide were Samsung , Apple and Huawei ; smartphone sales represented 78 percent of total mobile phone sales. For feature phones as of 2016 , the top-selling brands were Samsung, Nokia and Alcatel . Mobile phones are considered an important human invention as they have 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

3381-593: The growth of bandwidth-intensive applications, such as streaming media . 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. The first publicly available LTE service was launched in Scandinavia by TeliaSonera in 2009. In the 2010s, 4G technology has found diverse applications across various sectors, showcasing its versatility in delivering high-speed wireless communication, such as mobile broadband,

3450-625: The influence of European companies had significantly decreased due to fierce competition from American and Asian companies, to where most technical innovation had shifted. Apple and Google, both of the United States, also came to dominate mobile phone software. The world's largest individual mobile operator by number of subscribers is China Mobile , which has over 902 million mobile phone subscribers as of June 2018 . Over 50 mobile operators have over ten million subscribers each, and over 150 mobile operators had at least one million subscribers by

3519-433: The keypad has been replaced with a button that starts the music player on the phone. The Music Edition also includes a 2 GB miniSD card and the phone is completely black. The music player on the Music Edition supports album art and visualisations, while the regular N73 does not. Except the regular N73 has been updated firmware V4.0850.43.0.1. The Music Player application stays in the background at all time (even when music

3588-519: The phone boots up. Also, during recent UK Nokia poster campaigns, the black (ME) version of the phone was advertised without the term 'Music Edition', and the O2 UK shop sells the N73 in both Silver/Plum and Black, with the Black version having the multimedia button rather than the music button. In Taken (2008). When Peter took a photo for Kim and Amanda Mobile phone A mobile phone , or cell phone ,

3657-1060: The phone close to the ear. The typical lifespan of a mobile phone battery is approximately two to three years, although this varies based on usage patterns, environmental conditions, and overall care. Most modern mobile phones use lithium-ion (Li-ion) batteries, which are designed to endure between 500 and 2,500 charge cycles. The exact number of cycles depends on factors such as charging habits, operating temperature, and battery management systems. Li-ion batteries gradually degrade over time due to chemical aging, leading to reduced capacity and performance, often noticeable after one or two years of regular use. Unlike older battery types, such as nickel-metal hydride (Ni-MH), Li-ion batteries do not need to be fully discharged to maintain their longevity. In fact, they perform best when kept between 30% and 80% of their full charge. While practices such as avoiding excessive heat and minimizing overcharging can help preserve battery health, many modern devices include built-in safeguards. These safeguards, typically managed by

3726-425: The phone's internal battery management system (BMS), prevent overcharging by cutting off power once the battery reaches full capacity. Additionally, most contemporary chargers and devices are designed to regulate charging to minimize stress on the battery. Therefore, while good charging habits can positively impact battery longevity, most users benefit from these integrated protections, making battery maintenance less of

3795-424: The phone, or the installer application on the phone itself. The N73 uses a database system for the supplied 'Gallery' applications (which permanently run in the background, in order to reduce seek and operation times) and again these databases can be updated locally on the device itself. This means that supported image, video and audio files can be placed almost anywhere in the file system and browsed easily, and in

3864-483: The previous updates, plus the addition is the Nokia Mobile TV application also installed by default (requires an external Nokia Mobile TV Receiver SU-33W ) which is an application available on N77 . The camera is much improved from earlier firmware. In this update, the phone takes 27 seconds to boot, compared to 42 or more in previous versions. Also, the N73 has 20 MB of RAM available after boot. A little change

3933-545: The second-generation ( 2G ) digital cellular technology was launched in Finland by Radiolinja on the GSM standard. This sparked competition in the sector as the new operators challenged the incumbent 1G network operators. The GSM standard is a European initiative expressed at the CEPT ("Conférence Européenne des Postes et Telecommunications", European Postal and Telecommunications conference). The Franco-German R&D cooperation demonstrated

4002-503: The space on a device's front surface. Many smartphone displays have an aspect ratio of 16:9 , but taller aspect ratios became more common in 2017. Screen sizes are often measured in diagonal inches or millimeters ; feature phones generally have screen sizes below 90 millimetres (3.5 in). Phones with screens larger than 130 millimetres (5.2 in) are often called " phablets ." Smartphones with screens over 115 millimetres (4.5 in) in size are commonly difficult to use with only

4071-403: The subscriber's handset is too far away to be detected. The transmitter power of each base station is coordinated to efficiently service its own cell, but not to interfere with the cells further away. Automation embedded in the customer's handset and in the base stations control all phases of the call, from detecting the presence of a handset in a service area, temporary assignment of a channel to

4140-401: The technical feasibility, and in 1987, a Memorandum of Understanding was signed between 13 European countries that agreed to launch a commercial service by 1991. The first version of the GSM standard had 6,000 pages. The IEEE and RSE awarded Thomas Haug and Philippe Dupuis the 2018 James Clerk Maxwell medal for their contributions to the first digital mobile telephone standard. In 2018,

4209-460: 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. Mobile phones have central processing units (CPUs), similar to those in computers, but optimised to operate in low power environments. Mobile CPU performance depends not only on the clock rate (generally given in multiples of hertz ) but also

4278-412: Was attributed to the desire to obtain the lowest calling costs. When the removal of a SIM card is detected by the operating system, it may deny further operation until a reboot. Feature phones have basic software platforms. Smartphones have advanced software platforms. Android OS has been the best-selling OS worldwide on smartphones since 2011. A mobile app is a computer program designed to run on

4347-575: Was demonstrated by Martin Cooper of Motorola in New York City on 3 April 1973, using a handset weighing c. 2 kilograms (4.4 lbs). In 1979, Nippon Telegraph and Telephone (NTT) launched the world's first cellular network in Japan. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion; enough to provide one for every person on Earth. In

4416-431: 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. At the termination of the call the mobile operator would manually record the billing information. Mobile phones communicate with cell towers that are placed to give coverage across a telephone service area, which is divided up into 'cells'. Each cell uses

4485-540: Was followed in 1981 by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway, and Sweden. Several other countries then followed in the early to mid-1980s. These first-generation ( 1G ) systems could support far more simultaneous calls but still used analog cellular technology. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. In 1991,

4554-499: Was launched in Finland in 2000, and subsequently many organizations provided "on-demand" and "instant" news services by SMS. Multimedia Messaging Service (MMS) was introduced in March 2002. 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

4623-504: Was market leader in mobile phones. Nokia was the market leader in mobile phones from 1998 to 2012. In Q1 2012, Samsung surpassed Nokia, selling 93.5 million units as against Nokia's 82.7 million units. Samsung has retained its top position since then. Aside from Motorola, European brands such as Nokia, Siemens and Ericsson once held large sway over the global mobile phone market, and many new technologies were pioneered in Europe. By 2010,

4692-570: Was released in 2007. It became one of the top-selling Nseries devices during 2006 and 2007, and its high popularity helped Nokia's sales of 'multimedia' phones grow 28% year-on-year in Q3 2007 (according to Nokia the other top-selling from the line were the N70 and N95 ). In common with other Nokia 'Nseries' and 'Eseries' phones of its time (late 2006), the N73 comes loaded with many software applications, including contacts, messaging, picture and video galleries,
