The Côte d'Azur is made for moving: the promenade at Nice, the corniche roads up to Èze, the train that beads Cannes, Antibes and Monaco along the coast, and the perched villages behind. It's a summer of viewpoints, timed tickets and last-minute restaurant tables — all easier with a live connection. Whether you need to buy one depends on where you're coming from.
EU traveller? You might already be covered
France is in the EU. On an EU or EEA plan, "roam like at home" means your data works along the whole Riviera at your home rates — nothing to set up.
You'll want a travel eSIM if any of these apply:
- You're coming from outside the EU — the UK, Switzerland, the US, further afield.
- Your home plan has a roaming cap you'd blow through in a week.
- You want a separate data line and don't want to touch your main plan.
If so, install a France eSIM on home Wi-Fi before you travel and switch it on when you land at Nice Côte d'Azur.
What you'll actually use data for
- Maps and the coastal train between Nice, Antibes, Cannes and Monaco.
- Parking and the corniche routes up to Èze and the hill villages.
- Timed tickets and restaurant bookings for the Riviera's busy summer.
- Translation, photos and video calls from every viewpoint.
Two to three gigabytes covers a long weekend; four to six is safer for a week of driving the corniches and heavy navigation.
Tip: The three corniche roads above Nice and the drive into Monaco are where you'll lean on live maps most — and where a tunnel or a headland can drop signal for a minute. Cache offline maps before you set off so navigation never blinks.
If the Riviera is one stop on a bigger trip
France pairs easily with Italy just across the border, or with a wider European loop. If your summer touches several countries, a multi-country plan makes more sense than a stack of single-country ones — see One eSIM for a multi-country Europe trip. For city breaks in the same spirit there's Three days in Rome: staying online in Italy and A long weekend in Barcelona: staying online in Spain. And if France is home rather than a holiday — as it is for a large Kosovar and Albanian community — the cost of trips back is in Roots in Kosovo, life in France: cheap data both ways.
Off to the Côte d'Azur? Grab a France eSIM before you go and let the coast, not the settings menu, hold your attention.
