here is known problem in my Galaxy S 4SHV-E330K . I faced this problem for many days and was unable to use some GSM services like balance checking etc. Normally in other phone, I can check it with just dial *123#, now since
when I try to run USSD Code for checking balance. it start calling the code
I am using 4.4.2 kitkat.
I tried this on India, UK & Estonian sim cards but having same problem.
I tried to check/uncheck roaming data option also but no solution.
There is no solution in call setting s also.
Any genius from xda please help me to get rid of that please please please.
