Saily eSIM Review 2026: Real Test, Speed & Discount Codes

I’ve personally used Saily across Asia and Europe, including Thailand, Vietnam, and France — and it worked instantly in almost every real-world situation.

Whether you're traveling to Phuket, Rome, or Singapore, one thing is essential: reliable internet access.

Not just for browsing, but for real-life situations where you actually depend on your connection:

• 🚗 Booking an Uber or Grab after landing

• 🗺️ Finding restaurants, directions, or your hotel

• 📸 Sending photos and videos to family & friends

• 💳 Accessing banking apps, 2FA, and important emails

• 💻 Working remotely or joining video calls on the go

In the past, this was often stressful. High roaming fees or buying SIM cards at the airport made travel unnecessarily complicated.

After my first trip, I never went back to physical SIM cards.

My Real Experience with Saily eSIM

I’ve tested several eSIM providers before, but Saily stood out in terms of speed and ease of use.

I used Saily across multiple countries and real-world situations to see how reliable it actually is.

Here’s what I experienced:

Activation	Worked instantly after landing
Speed	Fast enough for video calls and streaming
Stability	Very reliable in cities
Weakness	Slight drops in rural areas
Would I use again?	Yes

Why airport SIM cards are outdated (and why eSIM is better)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. ✅

That’s why many travelers now choose eSIMs as the best option for international travel.

Saily eSIM Performance by Country (Thailand, Europe & more)

I tested Saily across several countries and continents. Here’s how it performed in real life:

🇹🇭 Thailand

If you're looking for a reliable eSIM in Thailand, Saily performed extremely well in my tests.

I often travel to Thailand for work, so having a stable connection is essential. I spent time in Bangkok, Chiang Mai, and while island hopping — and the connection was consistently strong.

What really surprised me was how often I still had signal, even in more remote areas. One moment that stood out was a bus ride from Chiang Mai to Chiang Rai.

We were literally driving through the countryside, and I was still able to work from my laptop using hotspot. That was honestly unexpected.

• ⚡ Instant 5G connection after landing

• 📶 Strong networks (AIS / True)

• 🏝️ Stable even on islands

Speed test: ~84 Mbps download (faster than many hotel Wi-Fis). This was even while connected to a VPN — perfect for hotspot and working remotely in places like Koh Kood.

Live Speed Test: I just ran this test here in Thailand. 84 Mbps download (via 5G) is faster than many hotel Wi-Fis. As you can see at the bottom, this speed is possible even while connected to NordVPN!

Reliable connection in Bangkok: Using Saily as a hotspot at The Yard Hostel to book my next flight. Even in busy environments with many connected devices, the speed was fast enough for secure transactions and travel planning.

🇻🇳 Vietnam

One moment that really convinced me was arriving in Hanoi, Vietnam.

I stepped out of the plane, opened my phone, and already had a stable 5G connection.

Within seconds, I booked a Grab ride from the airport. No Wi-Fi, no SIM card hassle, no stress after a long flight.

That’s when I realized how powerful eSIM can be in real travel situations — especially for international travel.

Perfect for multi-country travel:

• 🌍 No SIM switching

• 🔄 Automatic network switching

• 📦 Regional packages available

🇦🇪 Abu Dhabi

Worked perfectly in transit.

I’ve mostly used Saily at the airport during layovers, and the connection was always very strong. It’s perfect for getting work done during transit times.

I could easily use hotspot for video calls or quick tasks without relying on airport Wi-Fi.

• ⚡ Strong connection at the airport

• 💻 Stable hotspot for video calls

• 📶 Reliable even in high-load areas

🇪🇺 Europe (incl. France 2026 test)

A similar experience I had was in Montpellier, France, where I’m currently staying for a month (April 2026).

I walked into a café, opened my laptop, and used my phone as a hotspot — the connection was stable enough to work without relying on Wi-Fi.

I also liked that Saily is built by the NordVPN team, so combining it with a VPN was seamless. I used Saily Ultra with unlimited data and could even join Google Meet calls without worrying about limits or unstable connections.

For travelers working remotely or relying on mobile data, this is a huge advantage.

That’s something I didn’t expect, especially compared to unreliable hotel Wi-Fi.

• ⚡ Instant switch to local networks

• 📶 Strong connection in cities

• 💸 Often cheaper than roaming

👉 Live test in Montpellier (April 2026): Connection was stable within seconds after arrival.

Saily vs Airalo vs Holafly: Which is the best eSIM for international travel in 2026?

Feature	Saily	Airalo	Holafly
Price	$$	$$	$$$
Unlimited Data	✅	❌	✅
Setup	Very easy	Medium	Easy
Speed	Fast	Medium	Medium
Best for	Most travelers	Light users	Heavy users

Typical pricing: Saily plans often start around $4–$10 depending on the country and data package.

👉 My take:

Saily offers excellent value for the majority of travelers. Airalo can sometimes be slightly cheaper for very light use. Holafly makes sense if you need truly heavy unlimited data. Always compare prices for your exact destination and dates.

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.

👉 Fix: Make sure “Data Roaming” is turned on for the Saily eSIM.

Many travelers underestimate how much data they need.

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.

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 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 carrier-unlocked, otherwise, the eSIM will not activate.

---

Final Verdict: Is Saily eSIM worth it?

For US travelers in 2026, Saily is one of the best eSIM options for international travel — especially if you value simplicity and reliability.

It won’t be perfect in deep rural areas, but few eSIMs are. For most trips, it removes the stress of staying connected abroad.

Would I recommend it? Yes — I now use it on nearly every international trip.
