Saily eSIM Review (2026): Real-World Test in 11 Countries
This review is based on hands-on testing across 11 countries worldwide — including Thailand, Vietnam, France, Portugal, and the UAE.
I didn’t just test Saily at the airport. I used it in real situations where reliable internet actually matters:
booking rides right after landing
navigating in unfamiliar cities
joining video calls while traveling
using banking apps and 2FA securely
working remotely via hotspot with multiple devices
In most cases, Saily worked instantly and delivered stable 4G/5G connections — often faster and more reliable than hotel Wi-Fi.
Why reliable mobile data matters when traveling
Whether you're in Bangkok, Mallorca, or Singapore, mobile data isn’t just about convenience — it’s something you actively depend on:
🚗 Transportation: Booking Uber or Grab within seconds after landing
🗺️ Navigation: Finding hotels, restaurants, and directions
📸 Staying connected: Sending photos and videos without delays
💳 Security: Accessing banking apps, emails, and verification codes
💻 Work: Joining calls or working remotely via hotspot

👉 Biggest advantage for US travelers: No need to buy a SIM card at the airport. Your main US SIM stays active for calls, texts, and banking while data runs via the eSIM.
Why airport SIM cards are outdated (and why eSIM is better)
Many travelers still search for the best SIM card for international travel, but eSIMs like Saily are quickly replacing physical SIM cards — especially for frequent and international travelers.
If you're comparing eSIM vs physical SIM cards, the difference becomes obvious after your first trip.
⚠️ Risk of losing your primary SIM card
📩 Problems receiving important SMS (banking, 2FA, verification codes)
⏳ Wasted time buying a SIM card after a long flight
With Saily eSIM, your main SIM stays active and you get instant mobile data as soon as you land — no airport SIM card needed. ✅
Pro Security Tip: As a cybersecurity nerd, I always prefer a private eSIM hotspot over insecure airport or café Wi-Fi. It’s the simplest way to protect your banking and login data while traveling.
That’s why many travelers now choose eSIMs as the best option for international travel.
🌍 Saily eSIM Field Test: 11 Countries in Review
I didn't just test Saily for a few minutes at an airport; I put it through a long-term stress test across 11 countries in 2026. From remote islands in Asia to the highlands of Scotland, here is how it actually performed.
Quick Performance Overview
Country | Rating | Verdict for Remote Work & Daily Use |
|---|---|---|
🇫🇷 France | ⭐⭐⭐⭐⭐ | Winner: Flawless for Saily Ultra & Hotspot. |
🇪🇸 Spain | ⭐⭐⭐⭐⭐ | Top for Business: Handled live classes perfectly. |
🇹🇭 Thailand | ⭐⭐⭐⭐⭐ | Best Value: 5G almost everywhere, even on islands. |
🇵🇹 Portugal | ⭐⭐⭐⭐⭐ | Digital Hub: Very modern, high-speed network. |
🇸🇬 Singapore | ⭐⭐⭐⭐⭐ | Transit King: Instant and rock-solid connection. |
🇻🇳 Vietnam | ⭐⭐⭐⭐☆ | Surprise: Strong 4G/5G even in remote Sapa. |
🇦🇹 Austria | ⭐⭐⭐⭐☆ | Roadtrip Ready: Reliable for highway navigation. |
🇬🇧 UK / Scotland | ⭐⭐⭐⭐☆ | Solid: Steady performance in London & Highlands. |
🇮🇹 Italy | ⭐⭐⭐⭐☆ | Regional: Great in North; weaker in rural South. |
🇦🇪 UAE | ⭐⭐⭐⭐☆ | Transit Pro: Stable for airport video calls. |
🇩🇪 Germany | ⭐⭐⭐☆☆ | Mixed: 10/10 in cities; dead zones on trains. |
Detailed Real-World Experiences
🇫🇷 France: The "Mobile Office" Test
I spent a full month working from Montpellier, Paris, and Bordeaux. This was the ultimate stress test for the Saily Ultra (Unlimited) plan.
The Setup: Used Saily as a primary hub for 4 devices (2 laptops, 2 phones).
Performance: Seamless Web Development and CMS work.
Live Speed Test (Café in Montpellier): 70.94 Mbps Download / 35.61 Mbps Upload.
Verdict: Perfect for teams or digital nomads who can't rely on shaky hotel Wi-Fi.
In our latest field test, Saily handled a Google Meet video call on the A43 highway at 130 km/h. See the full technical breakdown in our Saily eSIM France Review (2026 update).
🇪🇸 Spain: The Teaching Test
In Mallorca (Port de Sóller) and the mainland, I used Saily for a high-stakes task: Live Online Teaching.
The Scenario: Teaching a class of 25 students via BigBlueButton.
Result: Video, audio, and screen sharing ran flawlessly without a single drop.
Verdict: If it can handle a 25-person live stream, it can handle anything.
🇮🇹 Italy: The Regional Reality
Tested in Laveno (Lake Maggiore), Elba Island, and Modena.
Experience: Perfect in the North and in tourist centers. On Elba Island, the signal was strong in towns but dropped in remote bays.
🇦🇹 Austria & 🇬🇧 UK / Scotland
Austria: Perfect for roadtrips (Vorarlberg/Highways). Navigation and Spotify ran flawlessly.
UK: Solid performance in London and stable enough for basic work while traveling through Scotland.
🇩🇪 Germany: The Infrastructure Reality Check
Tested in Munich, Hamburg, and Berlin.
Urban coverage is a flawless 10/10, but the German rail system remains a challenge in 2026.
City Life: 10/10. Flawless in urban hubs like Munich or Berlin.
The "ICE" Reality: Let's be honest—if you're in a total rural dead zone (Funkloch), no eSIM can save you. However, Saily is far more reliable than the notoriously unstable train Wi-Fi, which often fails even when a cellular signal is available.
The Test: We managed to hit 54.6 Mbps between Hannover and Hamburg.
Verdict: Don't rely on the Deutsche Bahn Wi-Fi. Use Saily for a direct connection, but expect intermittent drops during transit when the local infrastructure simply isn't there.
👉 Planning a trip across Europe?
🇹🇭 Thailand: The Island & Jungle Test
From the skyscrapers of Bangkok to the remote islands of Koh Kood and Koh Chang.
Surprise Moment: On a 3-hour bus ride from Chiang Mai to Chiang Rai, I stayed online and productive the entire time.
Network: Mostly 5G via AIS/True.
Weak Spot: Connection drops on speedboats far from the coast (expected).
Verdict: Better 5G coverage in the Thai jungle than in many parts of Europe.
🇻🇳 Vietnam: The 5G Surprise
Landing in Hanoi, I was online before the plane reached the gate.
Coverage: Impressive 4G/5G in Sapa and the northern valleys.
Utility: Essential for booking Grab rides instantly without hunting for airport Wi-Fi.
Verdict: Highly reliable even in mountainous regions.
🇦🇪 UAE (Abu Dhabi) & 🇸🇬 Singapore
The ultimate "Transit Tests." During layovers, I was online instantly. In Abu Dhabi, the connection was stable enough for quick video calls between flights.
💡 Pro Tip for Power Users (The Hotspot Factor)
As a tech expert, I rarely use a single device. In all 11 countries, Saily’s Hotspot/Tethering worked perfectly. Whether it was two laptops for work or sharing data with my partner, Saily handled the load without the artificial "throttling" you often see with local SIM cards.
Expert Verdict: For cities and tourist hubs, Saily is a 5/5. For rural road trips in Germany or Italy, always have an offline map downloaded, just in case the local towers let you down.
🏆 My Top 5 "Saily-Strong" Countries
If you are traveling to these destinations in 2026, Saily is a total "no-brainer":
🇫🇷 France – Best for Unlimited/Ultra Data: The ideal choice for power users and remote teams needing the Saily Ultra plan.
🇹🇭 Thailand – Fastest 5G Deployment: Experience high-speed internet even on remote islands and during long bus rides.
🇪🇸 Spain – Most Reliable for Video Calls: Rock-solid stability for professional meetings or live teaching from your hotel.
🇵🇹 Portugal – Most Modern Network Experience: Super-fast 5G infrastructure in digital hubs like Lisbon and Porto.
🇸🇬 Singapore – Smoothest Transit Experience: Get an instant, high-speed connection the second you land at Changi.

👉 Overall: a reliable and legitimate service.
Common eSIM setup mistakes (and how to avoid them)
Even though Saily is very easy to use, there are a few common mistakes travelers make when setting up an eSIM.
Here’s what to watch out for:
❌ Installing the eSIM too late
Many users try to install the eSIM after landing.
👉 Better: Install it at home before your trip so everything is ready when you arrive.
❌ Not selecting the eSIM for mobile data
After installation, some phones still use the main SIM for data.
👉 Fix: Go to your mobile settings and select Saily as your active data plan.
❌ Turning off roaming by mistake
eSIMs require roaming to be enabled, even though you’re not using your home carrier.
👉 Fix: Make sure “Data Roaming” is turned on for the Saily eSIM.
❌ Buying too little data
Many travelers underestimate how much data they need.
👉 Tip: Start with at least 5–10 GB for a typical trip.
Not sure how much data you actually need?
❌ Weak signal in rural areas
In remote locations, connection quality can drop slightly.
👉 Reality check: This happens with all providers, not just Saily.
💡 Pro Tip
Set up your eSIM before your trip, keep your main SIM active, and switch data to Saily after landing. That’s the easiest and most reliable setup.
FAQ: Saily eSIM Review & Pro Tips (2026)
Is Saily eSIM better than international roaming from US carriers?
Yes, for most travelers, Saily is significantly cheaper than international roaming plans from carriers like AT&T or Verizon. While US roaming often costs $10 per day, a Saily eSIM allows you to buy 5GB to 10GB for a fraction of that cost. Plus, you avoid "bill shock" because you only pay for the data you actually use.
Is there a Saily eSIM discount code for 2026?
Yes, you can use the promo code TECHNOVICE to get 10% off your Saily data plan. This code is verified for 2026 and works globally. Simply enter TECHNOVICE at the checkout screen in the Saily app to apply the savings.
Can I keep my US phone number active while using Saily?
Absolutely. This is one of the biggest advantages of eSIM technology. Your physical US SIM or primary eSIM remains active for calls and SMS (important for 2FA banking codes), while you assign "Cellular Data" to your Saily eSIM. This setup ensures you stay reachable on your main number without paying high data roaming fees.
Does Saily eSIM include calls and SMS?
No — Saily is data-only. This is standard for most travel eSIMs. Keep your physical US SIM active for calls, SMS, and 2FA. This is actually an advantage because you avoid expensive roaming fees while staying reachable on your main number.
Does Saily eSIM support hotspot and tethering?
Yes, Saily fully supports mobile hotspots and tethering on almost all plans. During my 2026 tests in France and Thailand, I was able to connect my laptop to my phone’s Saily 5G connection without any issues. This makes it an ideal solution for digital nomads or travelers who need to work from a café or hotel with weak Wi-Fi.
What happens if I run out of data during my trip?
Saily makes it very easy to "top up." You don't need to install a new eSIM; you simply open the Saily app, select your active plan, and buy additional GBs. The new data is added instantly to your existing eSIM, ensuring you never lose your connection while navigating or booking rides.
How do I know if my phone is compatible with Saily?
Most smartphones released after 2019 (like iPhone 11 and newer, Samsung Galaxy S20, or Google Pixel 4) are eSIM compatible. To be 100% sure, check your settings under "Cellular" or "Mobile Data" for an option like "Add eSIM." Also, ensure your device is fully carrier-unlocked. This is especially important for US travelers on payment plans with AT&T, T-Mobile, or Verizon; if the phone isn't paid off, the Saily eSIM will not activate.
Final Verdict: Is Saily eSIM worth it?
Yes — for most US and international travelers, Saily is one of the best eSIM options in 2026. It combines excellent speed, easy setup, strong city coverage, and great value (especially with code TECHNOVICE).
It shines in tourist areas and cities. In very remote rural spots you may experience weaker signals (same as most providers). For frequent travelers the new Ultra Plan is a game changer.
Would I recommend it? Absolutely — I now use it on nearly every international trip.
