Motorola Motofone F3
The Motorola F3, also marketed as the Motofone (styled MOTOFONE), is a candybar style GSM mobile phone from Motorola, released on 28 November 2006. A CDMA variant was released, F3c. It was the first mobile phone to use an electronic paper display. The Motofone F3 was designed to appeal to the low-end market and developing countries, and was thus less functional, but also less expensive than most phones. Motorola made it appealing to developing markets and people with reading and visual difficulties by using only simple symbols and using speech synthesis to identify tasks in the menu. Features Display technology The F3 was the first mobile phone to use electronic paper in its screen. Motorola used the term ClearVision to describe the new display, which was manufactured using E Ink's electrophoretic imaging film. The electronic paper main display allowed for the phone's thinness (no glass), longer battery life, and outdoor viewability (paper-like reflectivity). It had a backligh ...

Electronic Paper
Electronic paper or intelligent paper, is a display device that reflects ambient light, mimicking the appearance of ordinary ink on paper – unlike conventional flat-panel displays which need additional energy to emit their own light. This may make them more comfortable to read, and provide a wider viewing angle than most light-emitting displays. The contrast ratio in electronic displays available as of 2008 approaches newspaper, and newly developed displays are slightly better. An ideal e-paper display can be read in direct sunlight without the image appearing to fade. Technologies include Gyricon, electrophoretics, electrowetting, interferometry, and plasmonics. Many electronic paper technologies hold static text and images indefinitely without electricity. Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane. Applications of e-paper include electronic shelf labels and digital signage, bus station time tables, electronic billboard ...

TRS Connector
A phone connector is a family of cylindrically-shaped electrical connectors primarily for analog audio signals. Invented in the late 19th century for tele''phone'' switchboards, the phone connector remains in use for interfacing wired audio equipment, such as head''phones'', speakers, micro''phones'', mixing consoles, and electronic musical instruments (e.g. electric guitars, keyboards, and effects units). A ''male'' connector (a plug), is mated into a ''female'' connector (a socket), though other terminology is used. Plugs have 2 to 5 electrical contacts. The tip contact is indented with a groove. The sleeve contact is nearest the (conductive or insulated) handle. Contacts are insulated from each other by a band of non-conductive material. Between the tip and sleeve are 0 to 3 ring contacts. Since phone connectors have many uses, it is common to simply name the connector according to its number of rings: The sleeve is ''usually'' a common ground reference volta ...

SIM Lock
A SIM lock, simlock, network lock, carrier lock or (master) subsidy lock is a technical restriction built into GSM and CDMA mobile phones by mobile phone manufacturers for use by service providers to restrict the use of these phones to specific countries and/or networks. This is in contrast to a phone (retrospectively called SIM-free or unlocked) that does not impose any SIM restrictions. Generally phones can be locked to accept only Subscriber Identity Module, SIM cards with certain International Mobile Subscriber Identity, International Mobile Subscriber Identities (IMSIs); IMSIs may be restricted by: * Mobile country code (MCC; e.g., will only work with SIM issued in one country) * Mobile network code (MNC; e.g., AT&T Mobility, T-Mobile US, T-Mobile, Vodafone, Bell Mobility etc.) * Mobile subscriber identification number (MSIN; i.e., only one SIM can be used with the phone) Additionally, some phones, especially Nokia phones, are locked by group IDs (GIDs), restricting them to ...

Subscriber Identity Module
A typical SIM card (mini-SIM with micro-SIM cutout)A SIM card or SIM (subscriber identity module) is an integrated circuit (IC) intended to securely store an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephone devices (such as mobile phones, tablets, and laptops). SIMs are also able to store address book contacts information, and may be protected using a PIN code to prevent unauthorized use. SIMs are always used on GSM phones; for CDMA phones, they are needed only for LTE-capable handsets. SIM cards are also used in various satellite phones, smart watches, computers, or cameras. The first SIM cards were the size of credit and bank cards; sizes were reduced several times over the years, usually keeping electrical contacts the same, to fit smaller-sized devices. SIMs are transferable between different mobile devices by removing the card itself. Technically, the actual physic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
