Short notes on Telecommunications development and related technology in Qatar
What is USSD?
To make it simple, it is a command for your mobile phone that start with * or # and ends with #
in Qtel here's some useful USSD command:
Prepaid Hala Balance Query: *129# and press YES
Prepaid Hala Reload credit: *127*Secret Codes# and press YES
Credit transfer to other prepaid from Hala prepaid/postpaid Shahry users: *130*Destination mobile number*money value in Qatar Rial# and press YES
Please call 111 to activate your credit transfer feature from your Shahry postpaid and also BEWARE of fraud.
Some person receiveing an SMS instructing to do *130*YYY*VV# with no awareness of this USSD command and her Hala credit just vanished to another person!!!
USSD Menu Browser: *100# and press YES, new menu will pop-up from your phone screen
