Paris rewards the connected visitor: Métro routing through 300 stations, museum time-slots that sell out by morning, and café recommendations that separate the tourist traps from the neighborhood gems. Orange's network handles the City of Light's load with full Métro underground coverage, a quiet French infrastructure triumph.

CDG's Orange counter sells the €39.99 Holiday SIM, nearly triple a comparable eSIM. The RER B into town is covered but crowded; with data working from landing, you can judge whether the taxi flat-rate (€56 Right Bank) beats it for your group before reaching the platform.
Mobile coverage in Paris: what to expect
Comprehensive, all 20 arrondissements in 5G on Orange and SFR, and crucially the entire Métro and RER network underground. Montmartre's slopes, the Seine banks, Versailles' gardens (the far groves included) all hold strong signal. Paris solved underground coverage years before London.
Paris data tips from the ground
- Museum tickets are timed-entry apps now, Louvre, Orsay, Sainte-Chapelle slots vanish by morning in season; set booking alarms with working data.
- Citymapper handles the Métro/RER distinction and strike-day chaos (a recurring Parisian weather pattern) better than any paper map.
- Le Fooding and Google Maps reviews separate the €18 tourist-trap croque from the €9 masterpiece two streets over, data literally pays for itself here.

Does data work in the Paris Métro?
Yes, fully, all Métro and RER lines have complete underground 4G/5G coverage. Parisians doom-scroll between every station and visitors navigate seamlessly.
Does one France eSIM cover Versailles and Disneyland Paris day trips?
Yes, both sit inside Île-de-France's blanket coverage including the RER lines out. Versailles' vast gardens hold signal to the farthest fountain groves.
How much data for 4 days in Paris?
1.5-2GB handles navigation, bookings and photo uploads comfortably, Paris café Wi-Fi remains stubbornly mediocre, so the eSIM does carry the load.
