What are the popular codes for Samsung phones that I can use to get more information on my device?

March 15, 2020December 4, 2019 Kamal Kaur

Every cell phone comes with certain codes which when you dial you get information about your smartphone device. These codes dial just like USSD codes ( typical USSD message starts with an asterisk (*) followed by digits that comprise commands or data. Groups of digits may be separated by additional asterisks. The message is terminated with a hash symbol (#). ) but do not operate for any service provider. Such codes are phone specific and are different from the USSD code.

What is then the USSD code?

Unstructured Supplementary Service Data (USSD), sometimes referred to as “Quick Codes” or “Feature codes”, is a communications protocol used by GSM cellular telephones to communicate with the mobile network operator’s computers. USSD can be used 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.

USSD messages are up to 182 alphanumeric characters long. Unlike Short Message Service (SMS) messages, USSD messages create a real-time connection during a USSD session. The connection remains open, allowing a two-way exchange of a sequence of data. This makes USSD more responsive than services that use SMS.

How does USSD code work?

When a user sends a message to the phone company network, it is received by a computer dedicated to USSD. The computer’s response is sent back to the phone, generally in a basic format that can easily be seen on the phone display.

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. The vendor’s “check balance” application hides the details of the USSD protocol from the user. On some pay, as you go networks, once a user performs an action that costs money, the user sees a USSD message with his or her new balance. USSD can also be used to refill the balance on the user’s SIM card and to deliver one time passwords or PIN codes.

There are also MMI Supplementary Service codes; that are standardized so they are the same on every GSM phone. They are interpreted by the handset first before a corresponding command (not the code itself) is sent to the network. These codes might not always work when using an AT interface; there are standard AT commands defined for each of these actions instead.

Samsung codes

Samsung code is actually an alpha-numeric character which is used in Android devices. One can enter Samsung mobile codes using a phone book dialer. These codes are unique and specific to the manufacturer. It means codes for Samsung will not work in any other brand like Sony, HTC, Nokia etc. So, it is important to use Samsung mobile codes only on Samsung devices, not on other brands as it may be harmful and cause damage to other devices. Don’t experiment with such codes unnecessarily on other brands because it can alter the configuration of the device. Make sure you know what these codes are intended for, before using any Samsung codes.
