My dad lives in south america and wants to get an iPhone. Over there it costs upwards of $1000 for the base iphone 5 model. So he is asking me if I can get one here for cheaper and he pay me back for it. This is my first time doing this so Im looking for help on what I need to look for. I know his phone company uses sim cards, so Im looking for an att or T-mobile iPhone correct? And I need to get an unlocked phone to use with his provider? Does buying the phone off contract means that it is unlocked? Im sorry, as you can obviously tell Im not sure what Im looking for. Any pointing in the right direction would help.
