Airtel USSD codes list for balance, data, etc.
Airtel is one of India’s biggest GSM mobile network operators. Like any other mobile operator, Airtel has a list of USSD codes for various services to its subscribers, e.g., balance checks, validity checks, and others. The tutorial will describe a complete list of USSD codes for an Airtel subscriber.
USSD runs on standard GSM USSD protocols. A mobile subscriber may use a USSD code for a balance check for 3G/2G/4G data, validity check, etc. The home network of Airtel has a full subscription for a subscriber. The details include static information, e.g., name, address, etc., and dynamic information, location information, call balance, data balance, etc.
The subscriber may need to obtain details from the service provider occasionally for associated account balances or services. To get details, a subscriber dials a USSD code.
When an Airtel subscriber dials a valid USSD code, the mobile device sends the message with the code as a string to the network, and the mobile user sees that the USSD code is running on the device. Dialing a code creates a session between the handset and the USSD application for the code. The application displays the menu and takes user inputs.
The mobile operator can initiate the menu from an application without even dialing any code from the mobile device. This is called a network or mobile operator-initiated USSD session. Airtel may use this option to display using the menu to activate the service. E.g., when a mobile moves and the network detects the roaming, it sends the menu to activate a roaming pack.
Smart Phones and USSD code?
Mostly in urban areas, people have smartphones. On a smartphone, we can browse the Internet and also have apps. Airtel also interacts with subscribers via the Internet. Everything you can do with code can also do with the App or web. The following is one example of checking the balance.
