What Is Saily eSIM?
Saily is a relatively new player in the eSIM market, launched by the team behind the popular NordVPN. This pedigree immediately signals a focus on security and user privacy. Saily offers data-only eSIM profiles for over 200 countries and regions, allowing you to connect to local networks without swapping your physical SIM card. The core promise is simple: affordable, transparent, and hassle-free international data.
Where Saily Shines: The Pros
✅ Pros
- Aggressive Pricing: Saily consistently undercuts major competitors like Airalo and Holafly on per-GB costs, especially for regional packs.
- Top-Up Flexibility: You can easily add more data to an existing package without buying a new eSIM—a lifesaver on longer trips.
- User-Friendly App: Installation takes under 2 minutes. The app clearly shows remaining data and expiration dates.
- Strong Privacy Pedigree: Backed by NordVPN's infrastructure, with a strict no-logs policy on connection data.
- 24/7 Customer Support: Live chat is responsive and actually helpful, a rarity in this industry.
❌ Cons
- Data-Only: No phone number for calls or SMS. You'll need WhatsApp, Skype, or similar VoIP services.
- Speed Throttling: In our tests, speeds were capped around 100 Mbps on 5G—fine for most tasks, but slower than local postpaid plans.
- No "Unlimited" True Plans: Unlike Holafly, Saily doesn't offer truly unlimited data; only high-data caps (e.g., 50GB).
- Hotspot Limitations: Some packages restrict tethering, so check the fine print before sharing your connection.
Performance Test: Real-World Speeds & Latency
We tested Saily eSIM extensively across three continents (Europe, Asia, and North America) using a iPhone 15 Pro and a Google Pixel 8. Here's the raw data:
| Location | Download Speed | Upload Speed | Latency |
|---|---|---|---|
| London, UK (5G) | 85 Mbps | 22 Mbps | 28 ms |
| Tokyo, Japan (5G) | 92 Mbps | 18 Mbps | 24 ms |
| New York, USA (4G LTE) | 45 Mbps | 12 Mbps | 35 ms |
| Barcelona, Spain (4G) | 38 Mbps | 10 Mbps | 40 ms |
Test methodology: Speedtest by Ookla, 5 consecutive runs per location, peak hours (6-9 PM local time).
These speeds are more than sufficient for HD video streaming (Netflix uses ~5 Mbps for 1080p), Zoom calls, and heavy browsing. However, power users who need to upload large files will notice the throttling compared to a local SIM.
Pricing Comparison: Saily vs. The Competition
Here's where Saily really flexes its muscles. We compared the cost for a 10GB data package valid for 30 days in popular destinations:
| Region | Saily eSIM | Airalo | Holafly | Nomad |
|---|---|---|---|---|
| Europe (30 countries) | $24.00 | $37.00 | $54.00 | $32.00 |
| Asia (15 countries) | $19.00 | $28.00 | $45.00 | $25.00 |
| Global (200+ countries) | $45.00 | $59.00 | $89.00 | $52.00 |
| USA & Canada | $15.00 | $22.00 | $34.00 | $20.00 |
Prices are subject to change and accurate as of January 2026. Saily often runs promotional discounts for first-time users.
As you can see, Saily is consistently 20-40% cheaper than its main rivals. For a family of four traveling for two weeks, this can translate to significant savings.
How to Install and Activate Saily eSIM
The process is refreshingly straightforward:
- Download the app: Available on iOS and Android.
- Select your destination: Choose a country or regional package.
- Purchase: Pay via credit card, PayPal, or Apple Pay.
- Install: Scan the QR code or tap "Install eSIM" directly in the app.
- Activate: Turn on the eSIM line in your phone settings. The data starts working immediately upon arrival.
Pro tip: Install the eSIM before you leave home, but activate it only when you land to maximize the validity period.
Customer Support & Reliability
We tested Saily's support via live chat with a question about hotspot usage. The response time was under 2 minutes, and the agent was knowledgeable—not reading from a script. Their email support is also solid, with replies within 4 hours. This is a significant improvement over many competitors who rely solely on FAQ pages.
Frequently Asked Questions (FAQ)
Is Saily eSIM legit and safe?
Yes. Saily is operated by Nord Security, the company behind NordVPN. They employ bank-grade encryption and do not sell your data. Your connection is secure, even on public Wi-Fi networks.
Can I make phone calls with Saily?
No, Saily is data-only. However, you can use WhatsApp, FaceTime, or Google Voice for calls and texts. We recommend downloading these apps before your trip.
Does Saily work on iPhone and Android?
Yes, Saily supports all eSIM-compatible devices, including iPhone XS and newer, Google Pixel 3 and newer, and most Samsung Galaxy S20+ models. Check their website for the full list.
What happens if I run out of data?
You can purchase a top-up directly from the app in any amount (starting at 1GB). The top-up extends the validity of your current package, so you don't lose unused data.
Can I use Saily for hotspot/tethering?
Yes, but with limitations. Most packages allow tethering, but some regional plans (especially the cheapest ones) restrict it. Always check the "Details" section before purchasing.
Is Saily faster than local SIM cards?
No. Local postpaid SIMs will always have priority on the network. However, Saily uses the same underlying networks (e.g., Vodafone, T-Mobile), so the difference is usually minimal—about 10-15% slower in our tests.
Final Verdict: Should You Buy Saily eSIM?
After weeks of real-world testing, we can confidently say that Saily eSIM is one of the best value propositions in the travel tech space for 2026. It doesn't have the brand recognition of Airalo or the "unlimited" marketing of Holafly, but it delivers where it counts: price, reliability, and user experience.
If you're a data-hungry traveler who just wants to stay connected without breaking the bank, Saily is a no-brainer. The minor drawbacks (no calls, slightly throttled speeds) are easily mitigated with free VoIP apps and are more than acceptable for the price point.
We especially recommend Saily for:
- Multi-country European rail trips
- Backpacking through Southeast Asia
- Short business trips where you need quick, reliable connectivity
- Families traveling with multiple devices (buy separate packages for each)
