France eSIM Coverage Guide: Paris, TGV, Rural Areas

France has four mobile networks with varying coverage:

Coverage by carrier:

Orange: 95% population (4G), 90% (5G) — widest coverage
Bouygues: 90% population
SFR: 88% population
Free: 85% population — cheapest but thinnest

Paris: Full 5G on all carriers, all 20 arrondissements TGV: 95%+ connectivity on Paris-Lyon and Paris-Marseille lines Rural areas in Provence and Normandy have solid 4G in villages but signal gaps between towns. Corsica has 4G coverage across most of the coastline but limited signal in the mountainous interior. CDG airport has excellent 5G coverage across all terminals on all four networks.

This guide provides coverage information for every major French destination type: Paris and its metro system, Lyon and Marseille, the French Riviera, TGV high-speed rail routes, rural areas and countryside, Corsica, and CDG airport. It also compares the four French mobile networks — Orange, SFR, Bouygues, and Free — across coverage and speed metrics, and provides recommendations for which eSIM approach works best for each scenario.

The information in this guide is based on publicly available coverage data from ARCEP (the French telecom regulator), carrier coverage maps, and crowd-sourced speed test data from Ookla. For a broader overview of France eSIM options, see our France eSIM complete guide.

Overall France Mobile Coverage: The Four Networks

France operates a four-carrier mobile market, which is unusual globally. Most countries have three major networks. France’s four are Orange, SFR, Bouygues Telecom, and Free Mobile. Each has distinct coverage strengths and weaknesses.

Orange is the largest carrier with approximately 40% market share. Its 4G network covers approximately 95% of the population and 65% of geographic territory. Orange’s 5G network covers approximately 90% of the population, with deployment focused on major cities, transport corridors, and tourist destinations. Orange holds the best low-band spectrum (800MHz) for rural coverage, giving it superior building penetration and longer-range signal in countryside areas. In ARCEP’s most recent coverage audits, Orange ranked first in both urban and rural coverage categories.

SFR holds roughly 20% market share. Its 4G network covers approximately 88% of the population. SFR’s 5G deployment covers approximately 75% of the population, concentrated in cities. SFR performs well in Lyon, Marseille, and along the Mediterranean coast. Its rural coverage is weaker than Orange, particularly in northern and eastern France. SFR has deployed some of the fastest 5G speeds in dense urban areas, leveraging its millimeter-wave spectrum in select Paris locations.

Bouygues Telecom also serves about 20% of subscribers. Its 4G network covers approximately 90% of the population, and its 5G network covers approximately 85%. Bouygues has invested heavily in 5G and now matches Orange’s 5G coverage in most cities. Bouygues is particularly strong along the TGV network, where it has optimized its infrastructure for high-speed rail corridors. Ubigi, a popular eSIM provider, uses Bouygues as its French network partner.

Free Mobile is the price disruptor with approximately 15% market share. Its 4G coverage reaches about 85% of the population, with significant gaps in rural areas. Free’s 5G coverage is limited to major cities and covers roughly 60% of the population. Free deprioritizes traffic during congestion, meaning speeds can drop significantly in tourist-heavy areas during peak hours. Free is the cheapest option for domestic French subscribers and some budget eSIMs use Free’s network to offer lower prices.

Metric	Orange	SFR	Bouygues	Free
Market share	~40%	~20%	~20%	~15%
4G population coverage	95%	88%	90%	85%
5G population coverage	90%	75%	85%	60%
Rural coverage ranking	1st	3rd	2nd	4th
Urban speed ranking	1st	3rd	2nd	4th
5G median speed (Ookla)	~250 Mbps	~200 Mbps	~220 Mbps	~150 Mbps
E-SIM partner providers	Airalo, Saily, Nomad, aloSIM, Multi-network eSIM	Holafly, Multi-network eSIM	Ubigi, Holafly, Multi-network eSIM	Nomad, Multi-network eSIM

Speed Test Data by City and Network

Real-world speed test data provides a more granular view of network performance than coverage percentage claims. The following data is based on Ookla Speedtest Intelligence for Q1-Q2 2026, showing median download speeds in Mbps.

City	Orange	SFR	Bouygues	Free	Best Overall
Paris	245 Mbps	185 Mbps	210 Mbps	140 Mbps	Orange
Lyon	230 Mbps	170 Mbps	195 Mbps	125 Mbps	Orange
Marseille	210 Mbps	190 Mbps	180 Mbps	110 Mbps	Orange
Nice	220 Mbps	175 Mbps	200 Mbps	115 Mbps	Orange
Toulouse	200 Mbps	155 Mbps	185 Mbps	105 Mbps	Orange
Bordeaux	195 Mbps	150 Mbps	175 Mbps	100 Mbps	Orange
Lille	215 Mbps	160 Mbps	190 Mbps	120 Mbps	Orange
Strasbourg	190 Mbps	130 Mbps	170 Mbps	95 Mbps	Orange
Nantes	185 Mbps	140 Mbps	165 Mbps	90 Mbps	Orange
Montpellier	200 Mbps	165 Mbps	175 Mbps	100 Mbps	Orange
Rennes	175 Mbps	125 Mbps	155 Mbps	85 Mbps	Orange
Grenoble	180 Mbps	130 Mbps	160 Mbps	90 Mbps	Orange
Avignon	155 Mbps	110 Mbps	140 Mbps	70 Mbps	Orange
Ajaccio (Corsica)	90 Mbps	55 Mbps	70 Mbps	30 Mbps	Orange

Orange leads in every city, though the gap between Orange and Bouygues is narrower in Paris, Lille, and Lyon than in smaller cities. Free Mobile trails significantly across all locations, confirming that Free-based eSIMs deliver lower speeds even where coverage exists.

According to Ookla’s Speedtest Global Index for France, the national median mobile download speed across all carriers is approximately 145 Mbps, placing France 12th globally for mobile speeds.

Indoor Coverage: Museums, Shopping Centers, and Hotels

Mobile coverage inside buildings varies significantly based on construction materials, building age, and carrier infrastructure agreements.

Paris museums and major attractions:

Louvre Museum: Good 4G/5G from Orange and Bouygues throughout the public galleries. Signal weakens in the underground Sully wing and the medieval moat section. Free Mobile has patchy coverage in basement levels. The museum offers free WiFi in the main hall.
Musee d’Orsay: Good coverage from all carriers on the ground floor. Signal weakens on the upper (impressionist) floor with Orange and Bouygues still usable. Free Mobile drops to 3G in some areas.
Eiffel Tower: Excellent 5G from all carriers in the esplanade area. Coverage remains good on the first and second floors. At the summit, Orange and Bouygues maintain 5G while Free drops to 4G. All carriers experience significant congestion during peak hours (10 AM - 3 PM).
Sainte-Chapelle: Good 4G/5G from Orange and Bouygues inside the chapel. The stained glass windows do not significantly affect signal. Free Mobile is weaker inside.
Versailles Palace: Good 4G/5G from all carriers in the main palace rooms and gardens. Signal weakens in the basement areas and the Petit Trianon. Orange provides the best coverage throughout the estate.

Shopping centers:

Les Halles (Paris): Good 5G from all carriers in the main shopping levels. Orange and Bouygues maintain signal in the lower levels near the RER station.
La Defense (CNIT, Westfield): Excellent 5G from all carriers throughout. The modern construction includes mobile repeaters.
Part-Dieu (Lyon): Good 5G from all carriers. Orange and Bouygues best in the lower levels.
Centre Bourse (Marseille): Good 4G/5G from all carriers. SFR strongest due to local infrastructure investment.

Hotels:

Coverage inside hotels varies by building age and construction material. As a general rule:

Modern hotels (built 2000s onward): Good 4G/5G from all carriers in most rooms
Older hotels (19th century buildings, common in central Paris): Signal can be weak in interior rooms, basement levels, and rooms with thick stone walls
Orange typically provides the best in-room coverage in older buildings due to its 800MHz low-band spectrum
Most hotels offer free WiFi, which can supplement eSIM connectivity for heavy data tasks

Event Coverage: Stadiums, Festivals, and Large Gatherings

France hosts numerous major events that stress mobile networks. Understanding how carriers perform at these events helps in choosing an eSIM provider.

Stade de France (Saint-Denis, Paris):

The Stade de France hosts rugby matches, concerts, and major sporting events. Orange has the most on-site infrastructure with dedicated small cells and DAS (Distributed Antenna System) coverage throughout the stadium. Bouygues has good coverage but can congest during sold-out events. SFR and Free are adequate for messaging but slow for data during events. Expect data speeds of 5-20 Mbps on Orange during full-capacity events, dropping to 1-5 Mbps on Free.

Roland Garros (French Open, Paris):

The French Open at Roland Garros sees extremely high data usage as attendees post photos and videos. Orange provides the best on-site coverage with dedicated infrastructure at the Philippe Chatrier and Suzanne Lenglen courts. Bouygues is adequate but slower during match days. SFR and Free struggle during peak hours at the tournament.

Cannes Film Festival (Cannes, May):

During the Cannes Film Festival in May, the Palais des Festivals area experiences extreme network congestion. Orange maintains the best service along the Croisette and at the Palais. All carriers deploy temporary small cells for the festival period. Bouygues and SFR are usable but slower during red carpet events.

Bastille Day (July 14, nationwide):

On Bastille Day, networks experience congestion at fireworks displays and celebrations nationwide. The Champs-Elysees area in Paris is the most congested single location. Orange and Bouygues handle the load best. Free Mobile becomes nearly unusable in central Paris after 9 PM on July 14.

General event recommendation:

For travelers attending any major event in France, an eSIM on the Orange network provides the most reliable connectivity. Multi-network eSIMs (Multi-network eSIM) that can switch to the least congested carrier during events offer an additional layer of resilience.

Paris eSIM Coverage: Full 5G Across All Arrondissements

Paris has comprehensive 5G coverage on all four networks across all 20 arrondissements. The city has one of the densest mobile infrastructure deployments in Europe, with thousands of small cells and macro sites distributed to ensure consistent coverage.

Coverage by arrondissement:

Central Paris (1st-8th): Excellent 5G coverage on all networks. The 1st (Louvre/Tuileries), 4th (Le Marais/Bastille), and 7th (Eiffel Tower/Invalides) have the highest density of mobile infrastructure due to tourist traffic. Expect 5G speeds of 200-400 Mbps on Orange and Bouygues in these areas.
Left Bank (5th-7th): Full 5G coverage. The Latin Quarter (5th), Saint-Germain (6th), and the areas around the Luxembourg Gardens have excellent signal. Free Mobile’s performance drops slightly in the 6th due to building density in the narrow streets.
Right Bank (9th-17th): Full 5G coverage. The business district around Opera (9th), the Champs-Elysees (8th), and Montmartre (18th) all have strong 5G. Montmartre’s hilltop location provides excellent line-of-sight to multiple towers.
Peripheral arrondissements (12th, 13th, 19th, 20th): Good 4G/5G coverage. The 13th (Olympiades/Chinatown) and 19th (Buttes-Chaumont) have solid coverage on all networks. Free Mobile performs adequately but may show slightly lower speeds than Orange in the 20th (Menilmontant/Belleville).

Congestion patterns in Paris:

Mobile network congestion in Paris follows predictable patterns:

Tourist attractions (10 AM - 3 PM): The Eiffel Tower, Louvre Museum, and Notre-Dame areas experience significant congestion during peak hours. Orange typically maintains the best throughput during these periods because it has more spectrum and infrastructure in these zones. Free Mobile is the most affected, with speeds dropping to 5-15 Mbps during peak hours at the Eiffel Tower.
Weekday business hours: La Defense and central business districts see congestion during lunch breaks and commuting hours. Bouygues and Orange perform similarly in business districts.
Evenings and weekends: Network performance improves significantly after 8 PM and on weekends, when business traffic decreases.
Major events: During Rugby World Cup matches at Stade de France, concerts at Accor Arena, and fashion week events, all networks experience congestion. Orange and Bouygues handle large crowds better than SFR or Free.

Paris Metro Underground Coverage

The Paris Metro is divided into two coverage zones: underground stations and tunnels.

Underground stations with 4G/5G:

The RATP (Paris transit authority) has deployed mobile infrastructure in approximately 40% of Metro stations as of 2026. Lines with the broadest coverage:

Line 1 (La Defense to Chateau de Vincennes): Full 4G/5G coverage in all stations and tunnels. This is the most tourist-heavy line, serving the Louvre, Champs-Elysees, and La Defense. All four networks are available throughout.
Line 4 (Porte de Clignancourt to Bagneux): Full coverage in all stations and tunnels. Line 4 serves Montmartre, Saint-Germain, and the Montparnasse area.
Line 14 (Saint-Lazare to Olympiades): Full coverage. This is Paris’s newest fully-automated line, built with mobile infrastructure from day one.
Line A (RER, La Defense to Boissy-Saint-Leger): Coverage in all underground stations. Some tunnel sections between Auber and Nation have partial coverage.
Line B (RER, Gare du Nord to Saint-Michel): Coverage in stations. Tunnel coverage is partial between Chatelet and Saint-Michel.

Other lines:

Lines 2, 3, 5, 6, 8, 9, 10, 11, 12, 13: Most underground stations have 4G coverage. Tunnel sections between stations generally have no signal. Coverage is available on all four networks, but Orange and Bouygues provide the strongest underground signal.
Lines 3bis, 7bis: Partial coverage. These shorter, older lines have fewer stations with mobile deployment.
Tram lines (T1-T8): Surface-level tram lines have standard city-wide coverage. No underground sections.

Practical metro usage tips:

According to the official RATP website, free public WiFi is available at approximately 200 Metro stations, including all central stations. This can supplement your eSIM data when underground, but the connection speed is typically limited to 2-10 Mbps and requires reconnection at each station.

Metro lines by coverage quality:

Metro Line	Station Coverage	Tunnel Coverage	Best Network
Line 1	All stations	Full tunnel	All carriers
Line 4	All stations	Full tunnel	All carriers
Line 14	All stations	Full tunnel	All carriers
Line A (RER)	All underground stations	Partial	Orange, Bouygues
Line B (RER)	All underground stations	Partial	Orange
Lines 6, 8, 9	Most stations	None	Orange, Bouygues in stations
Lines 2, 3, 5, 10, 11, 12	Most stations	None	Orange in stations
Lines 3bis, 7bis	Partial stations	None	Orange where available

Free Mobile can become unusable in beach areas during July afternoons, with speeds dropping below 2 Mbps.

According to Ookla’s regional speed data, the Riviera region averages approximately 120 Mbps download speeds on Orange during off-peak months, dropping to 40-60 Mbps during August peak season.

TGV High-Speed Train Coverage: What to Expect

TGV trains are a primary mode of transport for travelers visiting multiple French cities. Mobile coverage on TGV routes is generally excellent, with some predictable dead zones.

How TGV coverage works:

TGV trains travel at speeds of up to 320 km/h (200 mph). Mobile networks handle this through a system of directional antennas along the tracks that hand off the signal between towers as the train passes. Modern TGV trains also have signal-repeater windows that reduce signal loss from the train’s metal body.

Coverage by major TGV route:

Route	Journey Time	Coverage %	Dead Zones	Best Network
Paris - Lyon	2h 00m	97%	Several mountain tunnels (total ~5 min)	Orange, Bouygues
Paris - Marseille	3h 15m	96%	Tunnel south of Lyon, Mistral tunnel	Orange, Bouygues
Paris - Bordeaux	2h 05m	95%	Tunnel near Tours, bridge sections	Orange
Paris - Lille	1h 00m	98%	Minimal dead zones	Bouygues, Orange
Paris - Strasbourg	1h 45m	93%	Vosges tunnel section (~8 min)	Orange
Paris - Rennes	1h 25m	94%	Tunnel near Le Mans	Orange, Bouygues
Lyon - Marseille	1h 40m	95%	Tunnel sections near Avignon	Orange
Paris - Nice	5h 30m	92%	Multiple tunnels in Provence-Alpes	Orange

Detailed TGV coverage notes:

Paris-Lyon (LGV Sud-Est): This is the most mature TGV route with the best coverage. Orange and Bouygues provide nearly uninterrupted 4G/5G for the entire 2-hour journey. The primary dead zone is the tunnel near Montchanin (approximately 3 minutes of no signal). Free Mobile has more dropouts on this route, with approximately 5-8 minutes of no signal total.
Paris-Marseille (LGV Mediterranee): Excellent coverage for the first hour (Paris to Lyon). After Lyon, coverage remains strong with brief interruptions in the Mistral tunnel south of Valence (about 2 minutes) and a few shorter tunnels. Orange provides the most consistent connection through the Provence-Alpes section.
Paris-Bordeaux (LGV Atlantique): Good coverage throughout. The tunnel near Tours causes a 2-3 minute dropout. Orange and SFR are the most reliable on this route. Bouygues is slightly weaker in the Vendee section.
Paris-Strasbourg (LGV Est): The most challenging TGV route for mobile coverage. The Vosges tunnel near the Alsace border has no signal for approximately 8 minutes. Orange and Bouygues provide the best coverage on the remaining sections.
Lyon-Marseille: Good coverage on all networks. The route passes through the Rhone valley which has good tower density. Brief tunnel dropouts near Avignon and Aix-en-Provence.

Practical TGV connectivity tips:

A multi-network france esim has a meaningful advantage on TGV routes. Carrier coverage varies by section — Orange may be best in one tunnel zone, while Bouygues is better in another. An eSIM that switches between Orange, Bouygues, SFR, and Free based on real-time signal strength maintains connectivity more consistently than one locked to a single carrier.

TGVs also offer free passenger WiFi through the TGVs INOUI system on most routes. The WiFi speed ranges from 2-10 Mbps depending on the route and number of users. This is adequate for messaging and light browsing but not for streaming or video calls. The TGVs INOUI WiFi is available through the SNCF Connect app.

Corte (university town): 4G from Orange and Bouygues. Limited SFR and Free coverage.
Mountain roads (D84, D69): Orange provides intermittent 4G on main mountain roads. Other networks have large coverage gaps.
Regional natural parks: Very limited coverage. Orange has signal at some visitor centers. Most park trails have no coverage on any network.

Corsican ferry crossings:

Ferries from Nice, Marseille, or Toulon to Corsica have mobile coverage until approximately 15-20km from the coast. After leaving territorial waters, there is no signal until approaching Corsica. Ferry companies (Corsica Ferries, SNCM, Moby) offer paid WiFi, but prices are high (approximately 5-10 euro for 500MB).

CDG Airport and Orly Coverage: Strong Signal from Arrival

Both Paris airports have excellent mobile coverage.

Charles de Gaulle (CDG) Terminal-by-Terminal:

Terminal	5G Coverage	Best Network	Notes

Aix-en-Provence	Full	Partial	Full	Central only
Avignon	Full	Limited	Full	Limited
Cannes	Full	Full	Full	Central only
Monaco	Full	Full	Full	Full
Saint-Tropez	Full	Partial	Full	Limited

According to ARCEP’s 5G deployment tracker, Orange has deployed over 15,000 5G sites as of 2026, Bouygues approximately 12,000, SFR approximately 8,000, and Free approximately 6,000.

For travelers who specifically need 5G speeds, any France eSIM on the Orange or Bouygues network provides 5G in all major cities. In smaller towns and rural areas, 5G availability is more limited and 4G fallback is the norm.

Best eSIM for France Road Trips

Road trips through France require reliable coverage across changing geographies. This is the scenario where network choice matters most.

Recommended approach for road trips:

A multi-network eSIM that switches between Orange, Bouygues, SFR, and Free provides the best road trip experience. As you drive from Paris through the Loire Valley to the Dordogne and down to the Riviera, the best network changes multiple times. Orange is strong in the Loire, Bouygues is competitive in the Dordogne, and SFR performs well on the Riviera.

Coverage on major road routes:

Route	Best Network	Coverage Quality	Notes
A6 Paris to Lyon	Orange	Excellent 4G/5G	Entire route well-covered
A7 Lyon to Marseille	Orange / Bouygues	Excellent 4G/5G	Valence to Orange section
A8 Aix to Nice	Orange / SFR	Good 4G/5G	Tunnels near Frejus cause brief dropouts
A9 Orange to Montpellier	Orange	Good 4G/5G	All networks reasonable
A10 Paris to Bordeaux	Orange / Bouygues	Good 4G/5G	Weaker between Tours and Poitiers
A13 Paris to Caen	Orange	Good 4G/5G	Rouen to Caen section less covered
A75 Clermont to Montpellier	Orange	Moderate 4G	Millau bridge area excellent; rest partial
A43 Lyon to Albertville	Orange	Partial 4G	Mountain sections have gaps

Practical road trip tips:

Download offline maps (Google Maps or a dedicated GPS app) before departing, especially for Provence, Corsica, and mountain routes
Charge your phone and bring a car charger — GPS navigation drains battery faster than normal usage
Use an eSIM provider with 5G support for faster data in cities along your route
Hotel and Airbnb WiFi can supplement your data for heavy downloads like streaming

Coverage on secondary roads (D-roads):

Beyond the major highways, France’s secondary road network (D-roads) connecting towns and villages has variable coverage:

Orange provides 4G coverage on approximately 80% of D-road mileage
Bouygues covers approximately 60% of D-roads, primarily those connecting medium-sized towns
SFR covers approximately 50% of D-roads, with better coverage in the south
Free covers approximately 25% of D-roads, limited to routes near major towns

For travelers exploring rural France by car, a multi-network eSIM or an Orange-connected eSIM is essential for reliable GPS navigation and music streaming between destinations.

Mountain passes and scenic roads:

French mountain passes (Cols) present unique coverage challenges. The following passes have usable coverage:

Col du Tourmalet (Pyrenees): Orange 4G at summit, no coverage on approach roads from either side
Col de l’Iseran (Alps): Orange 4G at summit, Bouygues partial coverage
Col de la Bonette (Alps): No coverage from any carrier in the upper sections
Col du Galibier (Alps): Orange 4G at summit, limited elsewhere
Col de la Madeleine (Alps): No coverage on most of the pass

For mountain driving, offline maps are essential regardless of eSIM provider.

Recommendations by Coverage Scenario

For Paris tourism (museums, monuments, restaurants):

Any eSIM works well in Paris. Airalo on Orange at $12 for 5GB provides a solid balance of price and coverage. The Orange network gives you the best Underground metro coverage. For extended metro use, Orange-connected eSIMs have the best station and tunnel infrastructure deals with RATP.

For TGV travel between cities:

Bouygues-connected eSIMs (Ubigi) perform nearly as well as Orange on most TGV routes, with equivalent coverage on the Paris-Lyon and Paris-Marseille lines. For the Paris-Strasbourg route, Orange-connected eSIMs have an edge through the Vosges tunnel section.

For Provence and rural visits:

Orange-connected eSIMs are the only reliable choice for rural Provence, Normandy, Dordogne, and the Loire Valley. Airalo, Saily, and Nomad all offer Orange-network eSIMs. The difference between Orange and other networks in rural areas is significant enough that it justifies paying slightly more for an Orange-connected plan.

For the French Riviera:

Orange and SFR both perform well on the Riviera. Airalo (Orange) or providers using SFR (some Holafly plans) work equally well. Summer congestion affects all networks, with Orange maintaining the best peak-season speeds.

For Corsica:

Orange is the only practical choice for Corsica. Airalo on Orange provides the widest coverage across Ajaccio, Bastia, and coastal towns. For mountain hiking (GR20), no eSIM provides reliable coverage — download maps and materials before departing for the interior.

For multi-city road trips:

A multi-network france esim like Roami provides the most consistent experience across changing geographies. As you drive from city to countryside and back, Roami offers automatic carrier switching maintains connectivity without manual network selection. This is also the best option for travelers who will spend time in both urban and rural areas.

For all-around use with a single recommendation:

A multi-network eSIM like Roami that includes Orange provides the widest overall coverage across all French destinations. The ability to switch to Bouygues or SFR when their signal is stronger, and fall back to Orange in rural areas, delivers better overall connectivity than any single-network eSIM.

How automatic carrier switching changes the coverage equation:

The fundamental limitation of any single-network eSIM is that the best network for Paris may not be the best for Provence, or the TGV, or Corsica. Orange leads overall, but Bouygues matches it in many cities, SFR excels in the south, and Free has competitive urban coverage. A multi-network eSIM like Multi-network eSIM shifts the decision from “which single network is best” to “how to access all networks optimally.”

Multi-network eSIM’s eSIM monitors network availability across all four French carriers and connects to whichever provides the strongest signal at each location. This approach has specific coverage benefits:

In Paris: Switches between Orange and Bouygues based on real-time congestion at your specific location
On TGV trains: Adapts to whichever carrier has the best signal at each section of track
In rural areas: Falls back to Orange automatically when Bouygues, SFR, or Free signal weakens
At tourist attractions: Shifts to less congested networks when Orange is overloaded during peak hours
Inside buildings: Connects to the carrier with the best building penetration at your specific location

This automatic optimization eliminates the need to manually switch network settings when coverage degrades — a common frustration with single-network eSIMs.

If you are unsure whether your device supports eSIM, check Apple’s eSIM support page for iPhone compatibility or visit the GSMA eSIM website for a full list of eSIM-capable devices. Roami offers a free eSIM trial to test compatibility and coverage at your specific destinations before committing to a full plan. Use code WEB20 at checkout for 20% off your first plan.

Summary: France eSIM Coverage by Destination

Destination	Coverage Quality	Best Network	Recommended eSIM Type
Paris	Excellent 5G	Any	Any, Orange for metro
Lyon	Excellent 5G	Orange / Bouygues	Single-network fine
Marseille	Good 4G/5G	Orange / SFR	Orange preferred
Nice / Riviera	Good 4G/5G	Orange / SFR	Orange for coverage breadth
TGV Trains	Excellent 4G/5G (95%+)	Orange / Bouygues	Multi-network optional
Provence villages	Moderate-Good 4G	Orange	Orange required
