How much data do I need for a trip to France?
Quick answers for a trip to France, using the same activity rates as our data calculator — then the local gotchas that change real-world use, and the cheapest plans we listed in our France guide.
Quick answer: plan size by trip length
Pick the column that matches how you use your phone. Light is maps and messaging; Typical adds social and a little video; Heavy adds streaming and some hotspot. Figures are the plan size we’d buy after the 15% buffer — not a guarantee of your phone’s meter.

Estimates use the same formula as our eSIM data calculator: activity rates × hours/day × days, plus a 15% buffer, rounded up to 1 / 3 / 5 / 10 / 20 GB or unlimited. No hotel Wi‑Fi assumed. Checked methodology 4 November 2026.

What makes data use in France different
- France plan or Europe plan? Staying in France, a country plan is often cheaper per GB. Crossing into Italy, Spain, Belgium or beyond, one Europe regional eSIM can beat buying two country packs — confirm France is on the list (it usually is).
- EES biometrics are in use on first Schengen entry for many travellers; ETIAS isn’t running yet. Budget airport time, not gigabytes, for that.
- Train Wi‑Fi on TGV is hit‑and‑miss. Don’t assume you can stream on rails; size maps and messaging as mobile.
- Plans are data‑only — keep your home SIM for SMS.
Networks named in our guide: France‑specific and Europe regional plans both sell well here — compare if you’ll cross a border.

Frequently asked questions
How much data for a week in Paris?
Typical use lands around 6 GB after the buffer — buy a 10 GB plan. Museum Wi‑Fi helps; Métro tunnels do not. Our France guide has full price tables.
Should I buy a France eSIM or a Europe eSIM?
France‑only if you won’t cross a border. Multi‑country itineraries almost always favour a Europe plan — check the country list and fair‑use rules.
Is 10 GB enough for two weeks in France?
Yes for typical sightseeing with hotel Wi‑Fi. Heavy hotspot or HD streaming points to Ubigi’s unlimited or a 20 GB fixed plan.
How does Signal Atlas calculate these numbers?
We use published planning rates (for example Netflix’s SD ≈ 0.7 GB/hr and Spotify Normal ≈ 72 MB/hr), multiply by hours per day and trip length, add a 15% buffer, and round up to a common plan size. Full methodology is on the calculator page.
