Phone bar code setting
As I am using the below mentioned OS version and Radio. I have a call barring for all outgoing INTERNATIONAL calls. Whenever I need to dial an int'l call. Thru the built-in selection for disabling the bar code, this options pops an error saying to check my phone settings!
But when I use the dial buttons to press the keys combination which my ISP provides #331*----# (dash are digits), this works on the spot in either cases, the on and off!
