The answer

Get a multi-country eSIM that covers every country on your route if your phone takes one and you want to keep your home number. On an iPhone, check the carrier lock first.

When to skip it

No eSIM, or a locked phone: get a SIM card instead. If a country on your route is missing from the list, look for a plan that includes it.

Questions people ask

What to know

  • To use your home number and a local data plan together, the iPhone must be carrier-unlocked. If it is locked, both plans must come from the same carrier.1
  • On Galaxy, the S26, S26+ and S26 Ultra take an eSIM, as do the S25, S25+, S25 Ultra and S25 Edge.
  • Which Galaxy models take an eSIM varies by country; in some, only the later models do. If yours is not listed, look in Settings for an option to add an eSIM.2
  • Coverage differs by product. Italy and everywhere else you will visit need to be in the product's country list.3
  • Before you buy, find out how the eSIM is installed and when the QR code arrives. Check that you can finish installing it on Wi-Fi before you leave.
  • An iPhone uses one line for data at a time. In Europe, switch mobile data to the travel eSIM.
  • On an iPhone you can keep your home number on one line and use the other as your travel line abroad.
  • iPhone 13 models and later take two eSIMs, so your home number can stay on an eSIM while you add one for Europe.
  • With data roaming on for the line that uses data, Visual Voicemail and MMS switch off on your home number.1

FAQ

Can I keep my home number on an iPhone with a Europe eSIM?
Yes, if the iPhone is carrier-unlocked. A locked iPhone needs both plans from the same carrier.
Does one Europe eSIM cover every country?
It depends on the product, so check that every country you will visit is in its list. The Japan eSIM page sets out which phones take one.
Can one iPhone hold two eSIMs?
Yes, on iPhone 13 models and later.
Which number does my iPhone use for data in Europe?
One at a time. Set mobile data to the travel eSIM. If you also want a lounge before the flight, compare a single visit with a Priority Pass before you go.
