If you’re planning to travel from France to Italy by train, I highly recommend sorting out your mobile data before you leave. I recently did this trip — from Paris to Milan — and having both Travel eSIM France and Travel eSIM Italy made a huge difference. No stress, no hunting for SIM cards, and no surprise bills.
Before the trip, I wasn’t even sure how eSIMs worked. But after a bit of research (and learning from a few mistakes), I figured out how useful they are — especially when you're crossing borders by train.
Why I Didn’t Rely on My Regular SIM
My usual SIM card works fine at home, but once I started traveling in Europe, I realized international roaming can get expensive fast. I checked my provider’s rates for France and Italy, and it just wasn’t worth it. Plus, I didn’t want to deal with weak signals or sudden disconnections during train rides.
I looked into local SIM cards, but the idea of lining up at a kiosk in a language I don’t speak wasn’t appealing either. That’s when I came across Travel eSIM France and Travel eSIM Italy. These are prepaid mobile data plans you install digitally — no shops, no SIM swapping. You scan a code, install the plan, and you’re connected.
Setting Up the eSIMs Before the Trip
A friend who travels often told me to install both eSIMs before I left. That turned out to be great advice. I bought a Travel eSIM France online and activated it the night before my flight. It worked as soon as I landed at Charles de Gaulle. Within a few seconds, I was online, booking a ride to my hotel and checking directions on Google Maps.
I also bought and installed a Travel eSIM Italy, even though I wouldn’t need it until later in the week. That way, I didn’t have to stress about doing it during the trip. Once both eSIMs were installed, I could switch between them in my phone settings.
If you’re wondering — yes, you can keep both on your phone, but you can only use one for mobile data at a time. When I was in France, I used the Travel eSIM France. Once I crossed into Italy, I switched to the Travel eSIM Italy in the settings. It took about 30 seconds.
The Train Ride: Where It Got Tricky
I took the TGV from Paris to Milan, which is a pretty smooth and scenic trip. It passes through Lyon, then into the Alps, and eventually drops down into Italy. The whole ride is about 7 hours.
Around halfway through the journey, the signal started to dip in the mountains. That’s expected — even the best eSIM can’t fix that. But the main issue was when we crossed into Italy. My French eSIM lost connection, and for a few minutes, I had no data at all. I had forgotten to switch to my Travel eSIM Italy.
Once I remembered and changed the setting, the phone connected to an Italian network quickly, and everything worked fine again. Lesson learned: it’s better to switch eSIMs before you hit the border, especially if you’re using maps, translation apps, or digital tickets during the ride.
Why I’d Use Travel eSIMs Again
For a multi-country trip like this, eSIMs saved me a lot of hassle. I didn’t have to search for SIM card vendors, didn’t overpay for data, and didn’t worry about language barriers when buying a local plan.
TheTravel eSIM France worked well in Paris, Lyon, and Nice. The signal was strong in most places, and I was able to use all the apps I needed — Google Maps, WhatsApp, Airbnb, and even YouTube during quiet moments on the train. The Travel eSIM Italy did just as well in Milan and Florence.
I also used the hotspot function to connect my tablet and didn’t face any throttling issues.
A Few Tips If You’re Doing This Too
-
Check if your phone is unlocked and supports eSIMs. Most recent iPhones and many Androids do.
-
Buy and install the eSIMs before your trip. Don’t wait until you’re in a train station or hotel lobby.
-
Switch eSIMs near the border. It helps avoid dead zones and roaming confusion.
-
Turn off roaming on your original SIM. That way, you don’t accidentally use it and get charged.
-
Download offline maps. Just in case you hit a tunnel or lose connection for a few minutes.
Final Thoughts
Taking the train from France to Italy is a great experience — it's scenic, relaxing, and easy to plan. But staying online during the trip can be tricky if you're not prepared. Having both aTravel eSIM France and a Travel eSIM Italy made things way simpler for me. It wasn’t about fancy features — just being able to check the platform number, look up a lunch spot, or text my host that I was running late.
If you’re doing a similar route, I’d say don’t wait to figure this out after landing. Set it up in advance, and the rest of your trip gets a lot smoother.
