The booking confirmation was in an email.
Not printed out. Not saved as a screenshot. In an email on a phone that had no data connection, sitting in a queue at a Spanish ferry terminal where the WiFi required a registration process that kept timing out and the queue was moving faster than the registration was resolving.
The ferry was for Mallorca. The booking had been made three weeks earlier. The confirmation number was somewhere in an inbox that required a data connection to open.
The ferry left on time. We were not on it.
The next one departed four hours later. The island of Mallorca was exactly as beautiful as it had always been. The four hours in the ferry terminal were less memorable — though entirely avoidable with thirty minutes of preparation before leaving home.
Why European Holidays Create Connectivity Gaps
A European holiday looks simple from the planning stage. Book the flights, sort the accommodation, research the restaurants. The phone will work when you get there — Europe is well covered, most places have WiFi, and everything will be fine.
This is broadly true. And slightly incomplete in ways that matter at specific moments.
Mobile connectivity in Europe is not a single unified environment. It is a collection of different network arrangements — carrier agreements, roaming structures, country-by-country variations — that behave differently depending on where you are, which home network you use, and which specific countries your plan actually covers.
Most European holidays proceed without any connectivity problem. The ones that do encounter problems tend to encounter them at the moments when connectivity matters most — at border crossings, at transport terminals, at the exact point where a confirmation number or a booking reference needs to load and does not.
What International Travellers Need to Know About European Roaming
The European connectivity landscape has shifted significantly in recent years.
Travellers from EU countries benefit from roaming regulations that limit what carriers can charge within the EU. For travellers from outside the EU — whether from North America, Australia, Asia, or anywhere else — those protections do not apply in the same way.
For international visitors to Europe, the situation depends entirely on the home carrier’s specific international arrangements — which countries they cover, at what daily rates, and with what data caps. These arrangements vary significantly between carriers and between destinations.
The traveller who checks their specific plan’s European coverage before departure — not the marketing language but the actual country list and daily rate — knows what to expect. The traveller who assumes Europe just works finds out the details at the point of connection.
The Countries That Catch Holiday Travellers Off Guard
These are the European destinations that most consistently fall outside standard international roaming arrangements — worth checking against your specific plan before booking:
Switzerland — Not EU. One of Europe’s most visited countries and one of the most frequently excluded from “Europe included” plans. Geneva, Zurich, the Alps, and the rail routes between France and Italy that pass through Swiss territory all require Swiss coverage.
Norway — Not EU. The fjords, Bergen, and Oslo attract significant visitor numbers annually. Often excluded from plans that cover neighbouring Scandinavian EU members.
Turkey — Not EU. Istanbul and the Turkish coast are popular European holiday destinations. Frequently absent from standard European roaming plans.
Iceland — Not EU. Reykjavik and the Ring Road have become major international travel destinations. Excluded from most standard European arrangements.
Canary Islands — Spanish territory, but some carriers handle them separately from mainland Spain. Tenerife, Gran Canaria, and Lanzarote are among the most visited destinations in Europe.
The gap between “Europe included” in marketing language and the specific countries actually covered is where most European connectivity problems begin.
Three Options — What Actually Works
Standard roaming through your home carrier
For holidays in countries your carrier covers at reasonable rates, roaming can be entirely adequate. The important step is verification before departure — checking the actual country list and daily rate rather than assuming.
For short trips of four or five days to well-covered destinations, roaming is simple and often sufficient. For two-week holidays crossing multiple countries, daily charges accumulate into a meaningful additional holiday cost.
Local SIM cards
Available in most European countries at airports and city phone shops. Local rates are genuinely cheaper than most international roaming arrangements. The logistics — passport registration, SIM swapping, losing your regular number for the duration — make this more practical for longer stays in one country than for holidays moving between destinations.
Multi-country travel eSIM
This is the approach that most travellers who plan their connectivity properly now use for European holidays.
An eSIM is a digital SIM built into modern smartphones. You purchase a Europe data plan before travelling, install it at home before you fly, and your phone connects to local networks automatically as you move across covered countries. Your home SIM stays in your phone throughout — your regular number active, calls and messages arriving normally. The eSIM handles data as a completely separate line.
Setup happens at home before departure. When you land at your European destination, your data is already working. No registration process at a ferry terminal. No loading spinner on an inbox that will not open.
After the Mallorca ferry situation, every subsequent European holiday has included a travel eSIM installed before departure. The confirmation email for that trip is now saved as a screenshot before we reach the terminal. The ferry booking is offline before we leave home.
I use easySim for European trips specifically because their 36-country coverage includes Switzerland, Norway, Iceland, Turkey, and the Canary Islands — the destinations that fall outside cheaper plans but appear regularly on real European holiday itineraries. For current plan options and pricing, the travel eSIM for Europe page has everything clearly laid out.

For a two-week European holiday with typical usage — navigation, messaging home, social media, restaurant research, booking excursions — the 5GB or 10GB plan covers most travellers comfortably.
The 10GB plan at £15.99 for two weeks compares to daily roaming charges that can reach £5 to £10 per day across multiple countries — a saving of between £54 and £124 on a standard two-week holiday.
All plans include full hotspot support with no daily cap restrictions. Sharing from one plan with a travel companion is unrestricted — one plan between two moderate users on a ten-day trip is often sufficient.
The Preparation That Actually Prevents Problems
Beyond choosing the right data plan, specific habits eliminate the majority of European holiday connectivity problems.
Save booking confirmations offline before you travel. Every hotel confirmation, every transport booking, every tour reservation — saved as a screenshot or downloaded PDF before departure. This removes any dependency on live data to access documentation at transport terminals or accommodation check-in.
Download offline maps for every destination. Google Maps offline areas work without mobile data. The GPS function in a phone uses satellite signals rather than network connection. Download holiday destinations before departure and navigation continues even in areas with limited signal.
Disable roaming on your home SIM before landing. Background apps consume data at international roaming rates from the moment a phone connects to a foreign network. Disabling data roaming on the home SIM before landing prevents parallel charges while the eSIM handles data.
iPhone: Settings → Mobile Service → home SIM → Data Roaming: off.
Android: Settings → Network & Internet → SIMs → home SIM → Roaming: off.

The Ferry Terminal Postscript
We went back to Mallorca the following year.
Travel eSIM installed at home before departure. Booking confirmation saved as a screenshot the evening before we left. Offline maps of the island downloaded before reaching the terminal.
At the ferry terminal, we walked to the check-in desk, showed the screenshot confirmation, and boarded. The process took about four minutes.
Mallorca was everything it had been on every previous visit — one of the Mediterranean’s genuinely extraordinary places. The terminal was a brief and entirely unremarkable part of getting there.
Prepare the connectivity before you leave home. Save the confirmations. Download the maps. Then spend the holiday on the parts that actually matter.
