⚡ The Verdict: Why Saily is a Lifesaver for Non-EU Travelers


If you are traveling from outside the EU/EEA—including the USA, Switzerland, Canada, or Australia—staying connected in France usually means one thing: The Roaming Trap.


While EU citizens enjoy "Roam like at Home," we are often hit with $10 to $15 daily fees from carriers like AT&T or Verizon. Even worse? Hunting for a SIM card kiosk at the airport while jet-lagged. I spent 30 days testing Saily to see if it’s the ultimate "set-and-forget" solution for both sightseeing and remote work.


  • ✅ Instant 5G: Connected immediately upon arrival (Orange/Bouygues networks).

  • ✅ Power User Friendly: Handled 4 devices (2 MacBooks + 2 iPhones) via hotspot daily.

  • ✅ No Paperwork: Skip the French kiosks. Unlike local physical SIMs, Saily requires no passport registration, no local address, and no French bank account. It’s 100% digital—buy it on your couch, use it the second you land at CDG.

  • ✅ Price: Starting at just $3.99 (Compare that to $300+ for monthly roaming!).

  • ❌ Indoor Limitation: Historic French stone walls are thick—sit near a window for the best speed!

💻 30 Days of Remote Work: The Montpellier Stress Test


I didn't just test Saily at the airport; I ran my agency with it for a full month. My setup was a massive stress test for any mobile connection:


  • Total Data Used: 59 GB.

  • Workload: I taught 4 online university classes via Google Meet and managed client campaigns daily.

  • Hotspot Sharing: I shared my connection with my girlfriend 24/7. We often had two iPhones and two MacBook Airs connected at once in local cafés.

☕ My Favorite "Mobile Offices" in Montpellier:


Saily provided a stable 5G connection in all these iconic spots:


  • Best Cafés for Work: Coldrip Food & Cafe, Cafe Bun, De la Sierra, and the terrace at MO.CO. Panacée.

  • Digital Nomad Spots: The Babel Community (Antigone) and Gazette Café.



The Tourist Survival Kit


Beyond work, Saily was my lifeline for the "vacation" side of the trip. Having a rock-solid 5G connection meant:


  • Instant Maps: No "GPS Signal Lost" while navigating the tiny, winding streets of Montpellier’s old town.

  • Uber & Transport: I could call an Uber or check the Tramway schedule the moment I stepped off the train, without begging for a café's Wi-Fi password.

  • Language Help: Real-time Google Translate at local markets (crucial when your French is limited to Bonjour!).

  • Apple/Google Pay: Reliable data ensures your digital wallet and transit apps work every single time you tap.

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. You can see the variety: from a blazing 354 Mbps in the city center to a solid 75 Mbps on the highway and 23 Mbps in rural valleys. It proves that while speeds vary by location, the connection remained reliable everywhere.

Case Study: High-Speed Connectivity on the French A43 (Villeurbanne)


To verify the network's handover capabilities and signal stability, I conducted a mobile stress test while traveling on the A43 autoroute near Villeurbanne.


  • Network Environment: Testing was performed at highway speeds (~130 km/h) to evaluate 5G cell tower switching.

  • Hardware: iPhone 15 Pro.

  • Active Workload: Concurrent Google Meet video conferencing and high-bitrate Spotify streaming.

  • Technical Performance (Measured near Villeurbanne):

    • Download Speed: 74.8 Mbps

    • Upload Speed: 8.70 Mbps

    • Latency (Ping): 62 ms

    • Jitter: 52 ms


Expert Verification: Even in high-mobility scenarios, Saily’s integration with the local infrastructure (Orange/Bouygues) maintained a consistent data stream. This proves the eSIM is suitable not just for static use, but for professional remote work and business continuity during transit across France.

FAQ: Saily eSIM France (2026)


Can I keep my original phone number active?

Absolutely. This is the best setup: Keep your primary SIM (US/Swiss/UK) ON for incoming SMS (important for 2FA banking codes), but set "Cellular Data" to Saily to avoid roaming charges.


Can I use Saily as a hotspot for my family?

Yes! I connected 4 devices simultaneously daily. It’s the perfect way for a family or couple to share one data plan.


Is Saily better than buying a SIM at a French kiosk?

Yes. You avoid the lines at the airport, and you don't need to provide a French address or ID. It’s 100% digital and works the second you land.


Does my phone need to be "Unlocked"?

Yes! This is a big one for US travelers. Ensure your phone is carrier-unlocked (especially if you're with AT&T or Verizon on a payment plan) so you can add the Saily eSIM profile.
