A mobile phone is an electronic devise used for long-range voice and data communications. Mobile phone features include the telephone, text messaging, email, gaming and Internet . A manufacturer will begin the process of creating a mobile phone by creating a blueprint, which is designed to surpass the previous model or start one from scratch. During the design process, decisions are made on features, such as cameras, GPS, Internet, MP3 player, games, radio, playback recording and anything else designers can think of including. Each feature of a mobile phone goes through a separate approval process to ensure its functionality and compatibility.
Once the parts are identified, some of them are created on-site, while others are bought from different companies. The parts of a mobile phone include the hard case, battery, volume control, keypad, headset socket and Bluetooth enabler. These are the parts that make up most mobile phones; they also include a microchip called a Subscriber Identity Module (SIM) card. According to SIMCard.org, a SIM card gives identity to a mobile phone and allows individuals to keep all their personal information on a chip, so that they can switch phones while maintaining their personal information. The parts of a cell phone are put together on an assembly line. The building that houses an assembly line is kept between 55 and 65 degrees F, to ensure that the parts and chips do not melt.
Once a mobile phone is put together, it goes through Quality Assurance (QA) testing before being packaged and sent out to distributors. During QA testing, each mobile phone is tested to ensure quality and functionality by testing the signal, battery power, texting, photo, video, volume and other functions. Once a mobile phone goes through QA testing, it is either sent back for correction or sent out for buyers.
