    How to disable call barring on iPhone 4s?


      I've been trying to call someone from Guam, but I just keep getting a BUSY tone. I already spoke with a CSR via chat and advised me that my call barring is active. I'm not even sure if my phone got that thing. I'm using iPhone 4s! Someone help me please
