Samsung Galaxy S (Android 2.1) USSD codes not working

Today, I wanted to use some of my carrier USSD codes (e.g. *120#) on my Galaxy S and they didn’t worked.

I entered them, but the Galaxy refused to display anything. After some searching I found out that this comes from the Mobile Tracker I had activated.

As soon as you active Mobile Tracker (Settings –> Location and security –> Mobile tracker) no USSD codes will work.

Disabled Mobile Tracker and the codes were working again. Go figure…


  1. Thanks for the information.
    I am exactly looking for the same.


  2. Does anybody can help to fix the same problem in Samsung Galaxy 5 GT-i5503 I couldn't fine mobile tracker in menu.

    thanks in advance

  3. Thanks. I am using Galaxy 3. It worked here after I disabled mobile tracker. But this is not the real solution. Hope Samsung will solve this issue on their next software update.
