ETSI and 3rd Generation Partnership Project (3GPP) standards, such as GSM and LTE, define supplementary service codes that make it possible to query and set certain service parameters (e.g., call forwarding) directly from mobile devices.
The user submits a code corresponding to the service available. USSD can be used to provide independent calling services such as a callback service (to reduce phone charges while roaming), enhance mobile marketing capabilities or interactive data services. USSD is commonly used by prepaid GSM cellular phones to query the available balance.
For example, the old style IMEI code 35-209900-176148-1 or IMEISV code 35-209900-176148-23 tells us the following: TAC: 35-2099 - issued by the BABT (code 35) with the allocation number 2099 FAC: 00 - indicating the phone was made during the transition period when FACs were being removed. SNR: 176148 - uniquely identifying a unit of this model
Every code that you enter over your phones keypad that contains asterisk (*) or hash (#) characters is an MMI code. MMI stands for Man-Machine-Interface. Even though most of these MMI codes look pretty similar, they fall into different groups with completely different actions. Some are just used locally on the device, some are sent to the SIM ...
USSD (Unstructured Supplementary Service Data) codes [1] are mobile dial codes that can be used for communicating with the service provider's computers (i.e. for WAP browsing, prepaid callback service, mobile-money services, location-based content services, menu-based information services, and as part of configuring the phone on the network).
The Type Allocation Code (TAC) is the initial eight-digit portion of the 15-digit IMEI and 16-digit IMEISV codes used to uniquely identify wireless devices. The Type Allocation Code identifies a particular model (and often revision) of wireless telephone for use on a GSM , UMTS , LTE , 5G NR , iDEN , Iridium or other IMEI-employing wireless ...
Parental punishments have officially gone digital. Ignore No More is an app created by a Texas mother Sharon Standifird that allows parents to lock their child's phone with a simple four-digit code.
Call forwarding, or call diversion, is a telephony feature of all telephone switching systems which redirects a telephone call to another destination, which may be, for example, a mobile or another telephone number where the desired called party is available.
