If you're heading overseas over the summer holidays, your phone plan is one of the easiest places to waste money. Roaming with your Australian carrier is simple, but it can be pricey. A travel eSIM, a digital SIM you buy and install before you go, can be cheaper, and since iOS 26 the iPhone has made the whole thing much smoother. It can now prompt you to switch to your travel eSIM when you land, and in some countries it switches back automatically when you come home.
