iPhone eSIM Setup for a Multi-Country Europe Trip
Install your Europe eSIM on iPhone before you fly: the Wi-Fi install at home, the Data Roaming toggle that matters, and what happens at each border.
Updated August 24, 2026
The problem this plan is built for is arithmetic. A trip that touches three European countries can mean three airport SIM counters, or three days of a carrier’s roaming pass, or one allowance that works in the EU and dies the moment the itinerary touches the UK, Switzerland or Türkiye — and if your contract is not European to begin with, there is no allowance at all. Multiply any of those by every country on the route and the phone becomes a recurring errand.
A prepaid data eSIM replaces that with one line. You buy a plan in the Europe eSIM app, install a digital line alongside the SIM you already use, and it stays attached across every country on the plan — each border is a network change the phone makes on its own, not a queue you stand in. Installing early costs nothing: validity starts when the line first connects inside the covered area. What we sell is on the pricing page, and what is an eSIM is the place to start if this is your first.
One limit, said plainly, because finding it out mid-trip ruins a day. The plan has a fixed country list, and a few corners of Europe are outside it — much of the Western Balkans, Moldova and the microstates among them. The list is on our home page and in the app before you pay; check the route against it while the route can still bend. The FAQ below names the usual surprises.
The rest of this page is the iPhone version: the install over Wi-Fi at home, then the settings that matter once you are moving — which line carries data, and Data Roaming on for the eSIM while it stays off on your own SIM. Where Apple has moved a menu between iOS versions it says so rather than insisting on one path. Travelling with an Android phone? Use the Samsung, Pixel or general Android guide.
Installation steps
-
Step 1
Buy your plan in the Europe eSIM app
Choose the data bundle that fits the trip — every plan covers the same list of countries, so you are choosing data, not geography. Once payment clears, the QR code and the manual activation details sit under your order and stay there, ready to open again from a hotel or a station platform.
-
Step 2
Install at home, on Wi-Fi, the night before
Adding an eSIM needs a working internet connection, and the worst place to discover that is an arrivals hall. Nothing starts running when you install: the plan's clock begins when the line first connects inside the covered area — which is why the next steps leave it switched off.
-
Step 3
Open Settings and find the cellular menu
Tap Settings, then the entry for mobile service. Apple has renamed this more than once: depending on your iOS version and where the phone was sold it reads Cellular, Mobile Data or Mobile Service. All three open the same screen.
-
Step 4
Tap Add eSIM, then Use QR Code
Recent iOS calls the button Add eSIM; older releases say Add Cellular Plan or Add Data Plan. Choose the QR code option — not Transfer From Nearby iPhone, which moves an existing line between handsets — and scan the code from a laptop or a second phone. With only one screen, tap Enter Details Manually and copy the SM-DP+ address and activation code from your order.
-
Step 5
Name the line, and leave it switched off for now
Label it Europe or Trip so the next few screens are unambiguous, and keep your usual SIM as the default for calls and messages. Then switch the new line off. This matters twice over if you live in a covered country: the plan starts the moment the line connects to any covered network, home ones included, so an enabled eSIM could start the clock before the trip does.
-
Step 6
Switch it on when the trip starts
On departure day — or on landing, if you are flying in from outside Europe — open the cellular menu, select the Europe eSIM line and turn it on. Then set it as the line that carries data. Your own SIM keeps your number.
-
Step 7
Data Roaming on for the eSIM, off for your own SIM
Open the Europe eSIM line and turn Data Roaming on. That toggle is how iOS lets a line use a network it does not belong to, and on this plan every network is a visited one — without it the line sits at no service. Then open your home SIM and check Data Roaming is off there. That is the switch that writes bills.
-
Step 8
At each border, give it a few minutes before you touch anything
The phone drops the old network and registers on the next country's by itself, usually within a few minutes — often before the train has left the border station. If the bars have not come back, toggle Airplane Mode off and on. If it still refuses, open the eSIM line's Network Selection, turn Automatic off, pick an available network, then set it back to Automatic later.
Troubleshooting
Does this plan cover every European country?
No, and it is worth checking before you book the route rather than after. The covered list — dozens of destinations, EU and non-EU alike — is printed on our home page and in the app before you pay. The places outside it are mostly the Western Balkans (Bosnia and Herzegovina, Montenegro, Albania, Kosovo), Moldova, and the microstates such as Andorra, Monaco and San Marino. The app sells separate plans for several of them.
The QR code will not scan. What else can I do?
Turn the brightness up on the screen showing the code, hold the iPhone about 20 to 30 cm back, and get the whole square in frame without glare. If it still will not read, tap Enter Details Manually and copy the details from your order. Manual entry produces exactly the same line.
There is no Add eSIM option, or I get an error adding it.
Open Settings, then General, then About, and look for an EID. If one is listed, the hardware supports eSIM and the block is almost certainly a carrier lock — your operator has to release the handset, which is a job for before you leave. No EID at all means the iPhone predates eSIM and needs a physical SIM.
I crossed a border and the eSIM shows no service.
Check three things in order: the line is switched on, it is selected as the one carrying data, and Data Roaming is on for it. Then toggle Airplane Mode to force a fresh search. If it is still blank after a few minutes, turn off automatic network selection on that line and pick one of the networks the phone lists locally.
Does turning Data Roaming on cost extra?
Not on this line. The plan is prepaid for use across the countries it covers, so no home operator is metering you — the toggle only tells iOS the line may register on a network that is not its own. Keep it off on your primary SIM, though: that one your carrier does meter, and an EU allowance stops applying the moment the trip leaves the EU.
Can my travel companions use it too?
Yes. Tethering is included, so run the Personal Hotspot from the phone holding the eSIM and let the rest of the table connect. The plan is data-only: no phone number, no calls, no SMS. That stays with your own SIM.
