Phone Unlocking
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 SIM cards with certain 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, 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 a single Mobile virtual network operator (MVNO) of a certain operator.

CDMA
Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference between the users, CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range. It is used as the access method in many mobile phone standards. IS-95, also called "cdmaOne", and its 3G evolution CDMA2000, are often simply referred to as "CDMA", but UMTS, the 3G standard used by GSM carriers, also uses "wideband CDMA", or W-CDMA, as well as TD-CDMA and TD-SCDMA, as its radio technologies. Many carriers (such as AT&T, U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Over The Air Programmable
An over-the-air update (or OTA update), also known as over-the-air programming (or OTA programming), is an update to an embedded system that is delivered through a wireless network, such as Wi-Fi or a cellular network. These embedded systems include mobile phones, tablets, set-top boxes, cars and telecommunications equipment. OTA updates for cars and internet of things devices can also be called firmware over-the-air (FOTA). Various components may be updated OTA, including the device's operating system, applications, configuration settings, or parameters like encryption keys. Terminology The term ''over-the-air update'' applies specifically to embedded systems, rather than non-embedded systems like computers. Before OTA updates, embedded devices could only be flashed through direct physical access (with a JTAG) or wired connections (usually through USB or a serial port). Purpose Over-the-air delivery may allow updates to be distributed at larger scales, reduce the cost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subsidy Password
The term, Subsidy Password, is used by Motorola and other handset manufacturers to refer to the 8-digit code (or 16-digit code for phones such as the Motorola K1) unlock code necessary to remove the operator lock (also known as subsidy lock) from cell phones. This code is randomly assigned to individual cell phones by the OEM on request of the mobile service operator and prevents the use of a particular phone on a cellular network other than that to which the phone was originally sold. Justification for use The term "subsidy" refers to the subsidization of cell phones sold to customers that purchase mobile phones as part of a contract with the mobile service operator. Many network operators provide these subsidies as an incentive for users to sign extended contracts, and use the subsidy lock as a means of protecting their investment. The installation of such locks means that users often are forced to purchase a different phone if they decide to switch their network (of advantag ...
