You bought an iPhone 17 and you are going travelling. The good news: you do not need to hunt for a shop at the airport or pay roaming. You can have your destination data sorted tonight, at home, in about two minutes.
It does. Every iPhone since the XS, back in 2018, works with eSIM, and the 17 is no exception. There are only two conditions, and neither is about the model: the phone must not be locked to a carrier, and iOS must be up to date.
If you bought the phone from Apple or paid for it outright, it is unlocked. If it came bundled with a monthly carrier contract, it may not be — and that is a phone call to that carrier, not to us.
This is the part almost everyone gets backwards. Installing an eSIM needs internet — and the moment you land is exactly when you have none. So install at home on Wi-Fi. Your data only starts counting when the eSIM connects to a network at your destination.
This is the question that stops most people buying, and the answer is simple: the travel eSIM comes in as a second line, for data only. Your number keeps receiving calls and texts as usual — including your bank codes, which is what actually matters when you are abroad.
All you do is choose, in settings, that the data line is the eSIM. Calls stay on your number; the internet comes from the travel plan, with no roaming charges.
Nearly always, it is a carrier lock. Before buying, check compatibility on the page for the destination you want — there is a checker there that tells you whether your phone takes an eSIM. A minute now beats an argument at the airport.
