I want to be able to Facetime with my family in Mexico. I don't know how to do this, I searched around. I live in L.A California, my family lives in Mexico city. I normally have to dial 01152 (international code) and then the phone number but it's not working. I tried just clicking the face time button and it also doesn't work. any help. obviously they have an Iphone 4 and I made sure their settings showed that you could do facetime. Thanks in advance.
