Activating iPhone outside the US
Hello, I am temporarily living in South America for a work assignment but still have my phone service with AT&T. I recently put in to upgrade for the iPhone 8 with AT&T and will be receiving it soon. My concern is, will I be able to activate the phone properly while I'm in South America? The iPhone is completely legal, not hacked or anything like that. AT&T gave me a number I could dial to activate the phone or they said I could switch the sim from my iPhone 6... any guidance would be helpful... thank you!
