Wi-Fi on trains in Europe: which ones have it, and how to get it to work

Train by train: the network to look for

• Deutsche Bahn: WIFIonICE on every ICE, free in first and second class, plus some IC and a few regional trains. The login page is LogIn.WIFIonICE.de.
• SNCF: _SNCF_WIFI_INOUI on TGV INOUI trains fitted with it. SNCF says it is not on TER or Transilien regional trains.
• Renfe: Wifi PlayRenfe on AVE, the AVE services between Spain and France, Avlo and most long-distance trains.
• ÖBB: the OEBB network on Railjets, Cityjets and some Nightjets.
• Eurostar: free Wi-Fi on all routes, including to and from London, after a sign-in with your name and email.
• Trenitalia: WiFi Frecciarossa on Frecciarossa trains, which asks for a phone number and a code sent by SMS.
• SBB: no Wi-Fi on Swiss domestic trains. The SBB-FREE network is on the Giruno and Astoro trains that run to Germany and Italy.

Open trains, private operators and night trains vary, so check the train's own page if you are counting on it for work.

Why the train Wi-Fi fades exactly where your phone does

A train is not wired to the internet. The router on board connects to the same mobile networks that your phone uses, and shares that connection with everyone in the carriages. Deutsche Bahn says its trains use several mobile operators in parallel, and Eurostar says it combines mobile signals along the route. So in a long tunnel or a mountain valley with no coverage, the Wi-Fi and your own data go quiet together.

The other limit is crowding. ÖBB points out that up to 400 passengers can share a Railjet's connection at the same time. Operators ask you to leave large downloads and system updates for later, and that is good advice for your own data too: download the film, the playlist and the next city's map before you board.

ÖBB's Railnet portal is the exception worth knowing: much of its film and series content is stored on the train itself, so it plays even where reception is weak.

When the login page never appears

Every one of these networks uses a login page that opens in your browser after you join, and that page is where most failures happen. If it does not pop up, type the address by hand: LogIn.WIFIonICE.de on ICE trains, wifi.sncf on TGV INOUI, railnet.oebb.at on ÖBB, register.onboard.eurostar.com on Eurostar and frecciaplay.it on Frecciarossa.

A VPN that is already running is the most common blocker. SNCF, ÖBB and Trenitalia all say it can stop the portal loading, so connect first, accept the terms, and turn the VPN on afterwards. ÖBB also suggests switching off iCloud Private Relay on an iPhone, and Trenitalia suggests turning off the random or private Wi-Fi address and forgetting the network before joining again. More on when a VPN is worth it is in our VPN guide.

Logins that need a code by SMS or a ticket number

Some trains want to know who you are before they let you online. Trenitalia's Frecciarossa Wi-Fi sends a code to the phone number you type in, and SBB-FREE can be unlocked with an SMS code or a SwissPass login. That code goes to a line with a number, which a data-only travel eSIM does not have, so it arrives on your usual SIM. Receiving texts in another EU country costs nothing extra under EU roaming rules, and our guide to getting SMS codes abroad covers how to keep that line reachable without paying for its data.

Renfe works differently: you log in with your ticket number or your Más Renfe number. If you are on an international train without a Renfe ticket, which can be the case on a rail pass, Renfe says to ask the on-board staff for a code.

Your rail pass needs a connection every day

If you travel on a mobile Interrail or Eurail pass, connectivity is not optional. The Interrail help centre says the pass must be online at least once every 24 hours, and that it is considered inactive until you reconnect and open the app. The app does not check in the background, so connecting the phone is not enough on its own: you have to open it.

Interrail says train Wi-Fi can do the job if the signal is at least three bars. In practice, the safest habit is to open the app each morning at the hostel, while you are still on Wi-Fi, before you head for the station. The Rail Planner timetables are designed to work offline once downloaded, but anything involving a live booking, such as a seat reservation, needs a connection.

Where you will be on your own data

Plan for no train Wi-Fi on regional and local trains, on Swiss domestic routes and on many smaller operators. Those are also the trains you are most likely to take on a pass, between the big high-speed legs. Switzerland has a free scheme called FreeSurf on its long-distance trains, but SBB says it needs a SIM or eSIM from a Swiss operator, so it does not help a visitor on a foreign plan.

On those stretches, a data plan that crosses borders with you is what keeps the map and the app working. Snoozim's Europe pack covers 33 countries, Switzerland and the United Kingdom included, and switches network by itself at each frontier. The Interrail eSIM guide lists the rail countries it does not cover, and if you plan to connect a laptop on board, the hotspot guide explains what to switch off first.
