TL;DR: Best eSIM for France (Hands-On Field Test & Measured Speeds)
Overall Pick: Saily is the overall pick for France, backed by TechNovice's 30-day hands-on field test in Montpellier (59 GB consumed across 4 simultaneous hotspot devices) with verified 5G speeds reaching up to 354 Mbps.
Airalo: Airalo provides fixed-data travel packages for France, but Airalo lacks Saily's unthrottled multi-device hotspot performance and integrated Nord Security features.
Holafly: Holafly offers unlimited data plans in France, but Holafly imposes strict daily fair-use hotspot limits and is significantly more expensive for standard 7–14 day trips compared to Saily.
Network Transparency: Saily connected directly to local carrier Orange France during physical outdoor field testing; regional network carrier availability across France is product page listed by Saily.
EU / UK / Swiss Roaming: EU travelers can utilize domestic mobile data in France under EU Roam Like at Home regulations; UK and Swiss travelers should verify home carrier EU roaming allowances before purchasing a Saily travel eSIM.

Research Box & Testing Methodology
Tested By: Nico Dudli (TechNovice)
Test Duration & Volume: 30-day field test in Montpellier, France (59 GB total data used across 4 simultaneous personal hotspot devices: 2 iPhones, 2 MacBooks).
Locations Tested: Montpellier (city center, local cafés), Saint-Guilhem-le-Désert, Palavas-les-Flots, Carnon, Annecy, and highway A9 (motorway between Montpellier and Nîmes at 130 km/h).
Networks Observed: Orange France (outdoor/rural), GSL Networks (indoor exit node).
Measured Speeds: Peak download speed of 354.3 Mbps (Outdoor 5G); 75.4 Mbps (Indoor 5G Café); 74.8 Mbps (Highway 5G at 130 km/h with active VPN); lowest speed of 23.2 Mbps (Rural LTE).
30 Days of Remote Work: The Montpellier Stress Test
Running an agency for a full month on Saily provided a rigorous real-world benchmark beyond standard airport connectivity tests:
Total Data Consumed: 59 GB over 30 days.
Workload: Taught 4 online university courses via Google Meet and managed daily client campaigns.
Multi-Device Tethering: Connected up to four devices simultaneously (2 iPhones, 2 MacBook Airs) in local cafés.
Verified Indoor Speed: 75.4 Mbps download at Café De la Sierra with two laptops active (Test ID: 7030759934).
Hotspot Tethering Speed: 31.7 Mbps verified on a secondary tethered device near Place de la Comédie.
My Favorite "Mobile Offices" in Montpellier
I used Saily while working from several locations around Montpellier. I did not publish a separate Speedtest ID for every café, so these locations are personal usage examples rather than individual benchmark tests.
Cafés where I worked: Coldrip Food & Cafe, Cafe Bun, De la Sierra, and the terrace at MO.CO. Panacée.
Other remote-work locations: The Babel Community (Antigone) and Gazette Café.
Everyday Travel Use in France
Outside remote work, I used the Saily connection for the everyday tasks that depend on mobile data while travelling:
Maps and navigation: loading maps, searching for destinations and checking live route information.
Transport: checking tram schedules and booking rides without relying on public Wi-Fi.
Translation: using online translation tools while shopping and travelling.
Travel apps: looking up restaurants, opening bookings and accessing web-based travel information.
GPS positioning itself does not require a mobile-data connection, and mobile wallets can perform many payment functions without continuous internet access. The practical benefit of the eSIM was keeping the surrounding travel apps and online services connected.

Saily vs. Airalo and Holafly for France
This article focuses on my real-world Saily test rather than reproducing a full provider comparison.
Saily worked particularly well for my trip because I needed hotspot sharing across several devices and enough connection stability for both normal travel use and remote work.
Airalo and Holafly use different plan structures and may suit different travellers. I compare those trade-offs separately in my Saily vs Airalo and Holafly vs Saily guides.
My recommendation in this France review is based on the Saily connection I actually used and measured. I did not run an equivalent 30-day France field test with Airalo or Holafly, so I do not use this article to rank their real-world French network performance.

Saily France Speed Test Results
During my published France tests, the Ookla logs identified Orange France on the outdoor and rural measurements and GSL Networks on the indoor Café De la Sierra measurement. The highway test was recorded while a VPN was active, so its network log cannot be used to identify the local mobile network. The results below are location-specific measurements, not a guarantee of nationwide performance:
Scenario | Download | Upload | Connection |
|---|---|---|---|
Outdoor (City Center) | 354.3 Mbps | 35.9 Mbps | 5G |
Indoor (Café De la Sierra) | 75.4 Mbps | 5.4 Mbps | 5G |
Rural (Saint-Guilhem) | 23.2 Mbps | 8.6 Mbps | LTE |
Highway (Traveling) | 74.8 Mbps | 8.7 Mbps | 5G |
Full transparency: I don't believe in cherry-picking only the best results. Here is my actual Ookla Speedtest log from the 30-day trip — from 354 Mbps in the city center to 75 Mbps on the highway and 23 Mbps in a rural valley. Speeds vary by location, but the connection remained usable everywhere I tested it.
Published test evidence: The measurements above come from my own Ookla Speedtest history, with individual result IDs so the tests can be independently referenced.
Scenario | Date | Test ID | Connection log |
|---|---|---|---|
Outdoor (City Center) | 18.04.2026, 14:05 | 7042939739 | Saily, Orange France, Lat 43.604 / Lon 3.872 |
Indoor (Café De la Sierra) | 08.04.2026, 21:46 | 7030759934 | Saily, GSL Networks, Lat 43.601 / Lon 3.865 |
Rural (Saint-Guilhem) | 24.04.2026, 13:39 | 7050265733 | Saily, Orange France, Lat 43.732 / Lon 3.554 |
Highway (Traveling) | 28.04.2026, 16:04 | 7055238377 | Saily, recorded with a VPN active — the connection log shows a Zürich exit node, but the test was taken on the motorway between Montpellier and Nîmes |
Coverage context: Public mobile-network coverage maps can help show where French operators report 4G and 5G availability, but they should not be treated as proof that a roaming eSIM will achieve the same coverage or performance everywhere. My conclusions in this review are therefore based on the locations I personally tested rather than a nationwide coverage claim.
Case Study: Highway Connectivity Between Montpellier and Nîmes
I ran a mobile connectivity test on the motorway between Montpellier and Nîmes to see whether the Saily connection remained usable while the phone was moving at highway speed.
Network environment: approximately 130 km/h during the documented test.
Hardware: iPhone 15 Pro.
Active workload: a concurrent Google Meet call and Spotify stream.
Measured performance:
Download Speed: 74.8 Mbps
Upload Speed: 8.70 Mbps
Latency (Ping): 62 ms
Jitter: 52 ms
Test ID 7055238377 was recorded on 28 April 2026 while I was travelling on the motorway between Montpellier and Nîmes. A VPN was active during the test, which is why the connection log shows a Zürich exit node rather than the physical test location.
Because the VPN was active, the 74.8 Mbps result should not be treated as a clean benchmark of raw Saily mobile-network performance. VPN routing and encryption can affect throughput and latency, and the Speedtest location field cannot independently verify the physical test location. The physical location is based on my trip record.
What this test showed: during this specific drive, the Saily data connection remained usable with the VPN enabled. A Google Meet call and Spotify stream continued while the measured connection reached 74.8 Mbps download with 62 ms latency. This is evidence of usable connectivity during that drive, not a nationwide motorway benchmark.
Saily vs. Home-Carrier Roaming
Whether a travel eSIM saves money depends on the roaming benefits already included in your home mobile plan.
Travellers from the EU may already have usable roaming in France under their domestic plan. Travellers from Switzerland, the United States and other non-EU markets should check their existing France or EU roaming allowance before buying an additional eSIM.
If your home plan includes little or no affordable data in France, a travel eSIM can provide a predictable alternative without changing your primary phone number.
I deliberately don't reproduce home-carrier roaming prices here, since those tariffs change frequently. Current Saily plan structures are covered in my Saily eSIM Plans guide, while current promotional codes and checkout tests are maintained in my Saily Coupon Guide.
Coverage: From the Beach to Medieval Villages
Road Trip Stability: We drove from Switzerland through Annecy to the South. The connection was stable on the highways for Spotify and navigation.
Rural Performance: We visited Saint-Guilhem-le-Désert. I saw a brief drop to 3G on the road, while the phone returned to 4G/5G service inside the village. My published rural Speedtest recorded 23.2 Mbps download over LTE.
Coastal Use: Solid signal at Palavas-les-Flots and Carnon beach for streaming and social media.
Final Verdict
Saily delivered reliable performance throughout my 30-day France test, seamlessly handling video calls, navigation, and multi-device hotspotting with measured download speeds ranging from 23.2 Mbps to 354 Mbps. While local network speeds naturally vary by location, Saily remains a top recommendation for travelers and remote workers who value easy setup and unthrottled tethering over uncapped unlimited-data plans.

FAQ: Saily eSIM France (2026)
Can I use Saily as a hotspot for my family?
Yes. During my France test, I connected up to four devices simultaneously, including two iPhones and two MacBooks. Hotspot conditions can depend on the current plan, so check the plan details if tethering is important for your trip.
Does my phone need to be carrier-unlocked?
Yes. Your phone must support eSIM and allow eSIM profiles from another provider. If your device was purchased through a mobile carrier, check its lock status before travelling rather than assuming an eSIM from Saily can be installed.
Having trouble after setup? Saily eSIM problems & fixes
Can I keep my original phone number, WhatsApp, and iMessage active?
Yes. On Dual SIM devices, you can keep your primary SIM active for calls and SMS while assigning Saily exclusively for mobile data. This allows WhatsApp and iMessage to remain registered to your original phone number without interruption. To avoid unexpected charges, make sure data roaming is enabled for your Saily eSIM line and disabled for your primary SIM line.
