Train travel in Europe is one of the most enjoyable experiences: sitting, watching the landscape, changing cities every day. But without mobile data, every stop in a new city becomes a search for Wi-Fi. eSIM is the perfect solution for the rail traveler: continuous coverage while crossing borders without changing SIMs.

Frequently Asked Questions
Do European trains have their own Wi-Fi?
Some do (ICE in Germany, TGV in France), but they are often slow and congested. They are not reliable for video calls or work. eSIM is much more consistent.
Does the European plan work while crossing borders by train?
Yes. The regional European plan automatically switches operators when crossing a border. You don't need to do anything — coverage is continuous.
How many GB do you use per week of train travel in Europe?
Between 5 and 15 GB/week for a traveler active on social media and maps. For more basic use (maps and messages), 3–5 GB/week.
Does the eSIM work on the Eurostar inside the Channel Tunnel?
No — there is no mobile coverage inside the undersea tunnel. It lasts about 20–35 minutes. Upon exiting on the other side, coverage automatically resumes.
Can I use the eSIM on the night train while I sleep?
Yes — the eSIM is active even if the phone is in sleep mode. When you wake up in the new country, the regional plan will already be using the local operator.
