Summer in Europe 2027: one eSIM for several countries

Planning a summer trip across Europe? How a Europe eSIM works across borders, which countries plans often leave out, and how much data you need.

One Europe eSIM can cover a whole summer trip across several countries, so you keep the same data plan when you cross a border by train, car or plane. Summer is peak season from June to August, so book early and install your plan before you fly.

Check the country list

Usually included: the EU countries, plus often Norway, Iceland and Switzerland.

Often left out: the UK, Turkey, and Balkan countries outside the EU such as Bosnia and Albania. Check the plan's country list.

Ferries and cruises: at sea, phones may connect to a ship network that charges extra. Turn data roaming off at sea.

How much data do you need?

Two weeks of normal use: about 15 GB.

A month or heavy use: 30 GB or more, or an unlimited plan where available.

See our guide to how much data you need for two weeks in Europe and our rail trip tips.

Set it up before you leave

Check that your phone is unlocked and supports eSIM on our supported devices page.

Buy a plan for your dates and install it at home on Wi-Fi.

When you land, turn on the travel eSIM, choose it for mobile data and turn on data roaming for it.

Keep your home line on for calls and texts, with its data roaming off.

Bottom line

Pick one Europe plan that lists every country on your route, and install it before you fly. See Europe eSIM plans.
