my operator have USSD (Unstructured Supplementary Service Data) menu when i call into number *108#

before i start call *108#, i set my log viewer (ALT LGLG) into debug info.


here is the related record:

a PhoneApp - OCC SS_CALL *108# 

a UI - GS+Q2 ...blabla..net.rim.device.apps.internal.phone.api.ui.UssdInputDialog 

a PhoneApp - PHONE-USSD-input=1 

a PhoneApp - PHONE-USSD blabla-the-ussd-content 

a CC - SSUssd,,0,"true" 


my questions are:

1. how i can programatically invoke call to *108#

2. how i can get the PHONE-USSD content like at the log viewer?

    is there any specific API?


thank you.

You can use the Invoke class to launch the Phone application and dial the number of your choice.  There are no methods to programmatically extract USSD data from a phone call.

       I am using the same way as you suggested. it works and confirms with all success message too. But at the same time on the back ground to my application screen, it gives an error message. 


      It does not throw any exception at my  Invoke.invokeApplication( Invoke.APP_TYPE_PHONE, phoneArgs ); call.


 What am i doing wrong? Any suggessions or hints?!!!

@MSohm, is it possible to create a downloadable icon that when clicked would trigger a USSD session shortcut like: Dial *150#


If so, where can I find information on how to do this?


Thanks in advance,

With my new Blackberry Tour 9630 I can't inquire from my GSM network. If I for example want to check my account balance I have to dial *102#. But this doesn't work with my new Tour instead it dials it as a phone number.

Can you help me on this? My blackberry curve 9300 works fine.

I'm new here and I don't know if there's any thread solving this matter. Please give the link if available
