So... let me start with saying that I know that the IPhone SE (model A1723) is the better choice for connectivity in Australia. It supports all the bands that are possibly used there. The model 1662 seems to be missing support for some of those bands. I have also see that some people say the A1662 will work there, though possibly with just a bit slower data. Any ideas if this is true? We are moving there soon and I'd hate to have to buy a new phone when the one I have is working well.
