Some of the USSD applications that we use regularly are

• Alerts About special offers, services and news
• Balance enquiry
• Changing tariff plan and subscribing to various VAS services.
• Recharging using prepaid vouchers

Other than these many interesting services can be given using the USSD platform. One such service is the “call back” service. The user will use USSD to send a USSD message to his friend asking him to call back. This is done by pressing the USSD service number and the number to which the alert needs to be send. Assume 14 is the service number and you want me to call you back. Press this on your mobile and press dial.

*14*9846831128#

I will receive a message, “XXXXXXXXXX wants you to call him back” where XXXXXXXXXX will be your number.

USSD supports interactive sessions where a service can be provided by using a menu. Micro payment market gets a real boom with the USSD technology in place. Users can transfer money from their mobile prepaid and post paid account to other mobile accounts. There will be a service number associated with it. When the user presses the number and dials, he will be presented with menus where he has to enter the amount and the mobile number to which the money needs to be transferred.

USSD is a session oriented technology and hence it supports menus and transactions. The state of the interaction between the user is tracked by the USSD server. Response times for USSD messages are shorter than SMS because SMS is a store and forward technology. All USSD services are accessed by dialing numbers between * and #. The handset recognizes those numbers and forwards the request to the USSD server instead of initializing a normal call or a data call. No additional application, phone menu or sim menu is needed for USSD to function as USSD is supported by every GSM handset.Similar Posts:
