Europe eSIM for multi-country trips: 49 countries, one plan, no borders

A Europe eSIM that crosses borders with you is the point of this plan. A European trip that takes in three countries used to mean three SIMs, or a home-carrier roaming pass that reset at every border. The Europe plan puts 49 countries on one eSIM, from Portugal to Turkey and Iceland to Cyprus, the UK and Switzerland included, with the phone switching networks by itself each time you cross. Add it at home, on Wi-Fi, and it's live the moment you land in the first of them.

Below: how the Europe plan works, how to set it up before you fly, exactly which countries it covers and which it doesn't, and what to expect from coverage in the cities, on the trains, and in the mountains.

Most travel eSIMs make you start over for every country, which in Europe means a new QR code every few days. KnowRoaming doesn't. You add the KnowRoaming eSIM, called KR.One, to your phone once, and from then on each trip is a plan you add to it: Europe now, Italy in the spring, the whole continent on a Europe plan when the itinerary gets ambitious. Nothing to scan again, nothing to delete when you get home.

The plan's days start when you turn it on and connect in any country on the plan, not at checkout. Buy it weeks ahead, add it at home, and a delayed flight costs you nothing. The full rule is in what plan validity means and when it starts.

Choose a fixed plan for a set amount of data at the lowest overall price, or an unlimited plan when you'd rather not count. Unlimited plans give you 5 GB a day at full speed, then a slower speed until the allowance resets the next day. If a fixed plan runs low, top up in the app and the extra data lands on the same eSIM.

See it in two minutes: Meet KR.One, iPhone setup with KR.One, or Samsung setup with KR.One.

Do this at home on Wi-Fi. It takes about a minute.

Before you leave

1. Get the KnowRoaming app (available on iOS and Android) and choose your Europe plan.
2. Tap Add. First time on this phone? The app adds KR.One and your Europe plan together. Already have KR.One? Only the plan is added, with nothing to scan.
3. Leave data roaming off on the KnowRoaming line until you land, and turn it off on your home line too so it doesn't run up charges in the background. Steps are in turning off roaming on your home line.

When you land

1. Turn the plan on in the app, then turn data roaming on for the KnowRoaming line. That setting lives in your phone, so the app can't flip it for you.
2. Give the phone a minute to find the network. If nothing happens, turn airplane mode on for 30 seconds and off again.

Prefer a QR code? The checkout page and your confirmation email both carry one; scan it from your phone's settings. Every tap, by device, is in adding your eSIM on iPhone, adding your eSIM on Android, and adding your eSIM on Samsung, or watch the iPhone QR walkthrough or the Samsung QR walkthrough. Still no signal after landing? Work through the no-signal checklist.

Western Europe: Belgium, France, Germany, Ireland, Luxembourg, the Netherlands, and the UK, with Jersey and the Isle of Man.

Southern Europe: Spain, Portugal, Italy, Malta, Greece, Cyprus, Gibraltar, San Marino, and Vatican City.

The Nordics: Denmark, Sweden, Norway, Finland, and Iceland.

Central Europe and the Alps: Austria, Switzerland, Liechtenstein, the Czech Republic, Slovakia, Hungary, Poland, and Slovenia.

The Baltics and the east: Estonia, Latvia, Lithuania, Belarus, Ukraine, Moldova, and Romania.

The Balkans and beyond: Croatia, Bosnia and Herzegovina, Serbia, North Macedonia, Albania, Bulgaria, Turkey, Georgia, Armenia, Azerbaijan, and Kazakhstan.

That's 49 countries on one plan with one data balance. The full list is also on the plan card above, under "Where this eSIM works"; check it against your route before you buy.

Five KnowRoaming destinations in Europe are sold as their own plans and are not on this one: Andorra, Monaco, Montenegro, the Faroe Islands, and Guernsey. Andorra and Monaco catch people out, since both are surrounded by countries the plan covers; add the country's own plan to the same eSIM for that leg. Kosovo is covered by the Global plan only. Read crossing into a border country your plan doesn't include before a route that crosses into a country the plan doesn't include.

Paris to Amsterdam, Vienna to Budapest, Copenhagen to Malmö, London to Brussels on the Eurostar: the plan switches networks by itself as the train crosses, and there is nothing to change in the app. Keep data roaming on for the KnowRoaming line the whole trip, since that is the one setting the app can't change for you, and give the phone a minute after a crossing; if it hasn't found the new network, airplane mode on and off forces a fresh search. The days keep counting from the first time you connected, wherever that was.

In every country the plan connects to a local partner network, with 5G in 43 of the 49 and 4G LTE in the rest, including Bosnia and Herzegovina, Georgia, Gibraltar, and Ukraine. Your phone picks the network automatically once the plan is on; there is nothing to choose by hand.

Europe is densely covered, and the gaps are the predictable ones: the high Alps and Pyrenees above the resort bases, the Scottish Highlands and Norwegian fjords between towns, the Greek island ferries, and the tunnels on the fast lines. Download maps for those legs and expect the signal back at the next town.

A month on the trains is the trip the Europe plan was made for. An unlimited plan, with 5 GB a day at full speed and slower after, covers navigation, bookings, video calls, and a laptop on the hotspot for the whole route; a fixed plan suits a two-country week. Both are on the plan selector at the top of this page, and a plan can be topped up or a new one added from the app anywhere on the route.

July and August fill the trains, the ferries, and the museums' timed-ticket queues, and the shoulder months either side are the ones to aim for; December is the Christmas-market season in the German-speaking countries and the Nordics. Ferry and rail timetables thin in winter on the islands and in the north; check them in the operators' apps rather than trusting summer memory.

Most phones sold since 2019 support eSIM, including iPhone XS and later and most Android flagships from the same window. Check yours before you add a plan; it takes a few seconds. On iPhone, go to Settings, General, About and look for an EID or Available SIM. On Android, go to Settings, Network & Internet, SIMs and look for an option to add an eSIM. On Samsung, dial *#06# and look for an EID.

Your phone also needs to be carrier-unlocked. If you're not sure, carrier-locked vs unlocked: how to tell shows you where to look.

Adding a Europe plan doesn't touch your regular SIM. Calls and texts on your usual number keep working exactly as before. The new plan handles data while you're there, and most phones run both at once without you doing anything else. Bank codes and two-factor texts still arrive on your home number, as long as that line stays switched on.

For a European trip the real competition isn't another eSIM. It's your home carrier's roaming add-on, priced for a weekend and throttled by midweek; the SIM counter in arrivals, after the flight, with a queue; and café Wi-Fi, in a country where even the bus ticket is in an app. A Europe plan added at home beats all three: one price agreed before you fly, live the second you land, and a Europe plan waiting if the trip grows.
