I noticed that USSD codes (i.e codes checking for balance etc, eg: *111#) are not well supported on our Lumia. Sometimes it really takes ages to process and display the response, and many times it would just hang on 'waiting..' screen and finally i have to dismiss it and try again.
Again the response oriented USSD codes dosent suport at all. As in my Vodafone prepaid, on dialing on *111# I get a response screen with selection of 5 option eg: 1. Check Balance, 2. Data Plans, 3. etc. if it sometimes displays me the option menu, there is no space given to input my selected option (like if I need to know my Data Plan I need to press 2 and send ok), and thus cant do anything.
any workaround for this.
