1. What is Saily and How Does It Work?
Saily is a modern travel eSIM application developed by Nord Security, the world-famous cybersecurity firm behind NordVPN and NordPass. Launched to address the growing demand for flexible, secure, and user-friendly international roaming alternatives, Saily operates entirely through a mobile app available on iOS and Android.
Unlike traditional eSIM providers that require scanning QR codes from a secondary screen, Saily offers a streamlined, single-device installation process:
- Direct App Setup: Download the Saily app, select your country destination, buy a plan, and install the eSIM profile directly on your phone with a single click.
- Security & Privacy Focus: Backed by Nord Security, Saily places a heavy emphasis on data encryption and security, making it a reliable option when connecting to unfamiliar networks.
- Flexible Packages: Rather than paying for unlimited data you might not use, Saily focuses on cheap, pay-per-gigabyte plans tailored for different lengths of stay.
- Simple Interface: The app features a minimalist design, making it easy to check data balance and purchase top-ups on the go.
2. Saily Coverage and Supported Networks
Saily offers connectivity in over 180 countries and regions around the world, making it highly competitive with the largest providers in the market. Since Saily is developed by Nord Security, they partner with leading local telecommunications companies in each country to provide stable roaming connections.
Here is a breakdown of their primary network partners:
- United States: Seamlessly routes through the networks of T-Mobile and AT&T, ensuring wide coverage.
- Europe: Connects to premium national operators such as Orange, Vodafone, and Deutsche Telekom depending on the country.
- Asia: Partners with top networks like Singtel in Singapore, SoftBank in Japan, and SK Telecom in South Korea.
- Global Roaming: Automatically connects to the fastest available local network standard (5G or 4G LTE) and handles carrier switching dynamically as you travel.
This network variety ensures that travelers experience minimal dead zones, even when traveling outside of major metropolitan cities.
3. Speed Test Results: How Fast is Saily?
We conducted real-world connection speed tests using Saily eSIMs in several international hubs. The results showed excellent latency control and high-speed throughput, which is expected from a Nord Security product:
- New York, USA (on T-Mobile 5G): We recorded download speeds averaging 72 Mbps and upload speeds of 14 Mbps. Web pages loaded instantly, and streaming Spotify was seamless.
- Paris, France (on Orange 5G): Download speeds averaged 58 Mbps with upload speeds around 10 Mbps. Latency was low (around 45ms), making it ideal for Google Maps navigation.
- Tokyo, Japan (on SoftBank 4G LTE): Download speeds hovered around 40 Mbps with upload speeds of 8 Mbps. The connection was stable throughout crowded commuter trains.
- Overall Latency: Ping times stayed between 40ms and 90ms, which is very snappy for international routing.
Connection stability was exceptionally high, with minimal packet loss or sudden drop-offs, making Saily a very dependable option for basic navigation and messaging.
4. Saily Pricing and Data Plans
Saily’s pricing is structured on a pay-per-GB model, making it incredibly cheap for budget-conscious travelers or those who only need minimal data. Plans are available in 1GB, 3GB, 5GB, 10GB, and 20GB packages, with validity ranging from 7 to 30 days.
Unlike unlimited models, you only pay for the data you plan to consume, meaning no wasted expenditure.

6. Comparison with Competitors: Saily vs Holafly vs Airalo
To understand where Saily stands in the travel eSIM market, we can compare it directly to the segment leader Airalo and the unlimited-specialist Holafly.
- Saily vs Airalo: Both focus on the pay-per-GB model. However, Saily is backed by Nord Security, providing a simpler in-app installation flow and often more competitive pricing for larger gigabyte buckets in popular destinations.
- Saily vs Holafly: Holafly focuses entirely on unlimited data plans starting at $19, whereas Saily focuses on cheap budget plans starting at $4.29. If you do not need unlimited data or need to share data via hotspot, Saily is the superior choice.
| Feature | Saily | Airalo | Holafly |
|---|---|---|---|
| Primary Model | Pay-per-GB Packages | Pay-per-GB Packages | Unlimited Data Plans |
| Entry Price | From $4.29 | From $4.50 | From $19.00 |
| Best For | Budget Travelers & Hotspot Users | General Travelers & Light Usage | Heavy Data Users & Live Streaming |
| Setup Method | Direct In-App Setup (Very Easy) | In-App / QR Code (Easy) | QR Code / App (Average) |
| Hotspot / Tethering | Allowed (All plans) | Allowed (All plans) | Disabled (Most plans) |
7. How to Install and Activate a Saily eSIM
Installing a Saily eSIM is incredibly simple because it uses the app-direct setup method, eliminating the need for a secondary device or paper copies of QR codes.
- Download the App: Install the official Saily app from the Google Play Store or Apple App Store.
- Choose a Plan: Select your destination country, select your desired data package (e.g. 5GB for 30 Days), and check out securely.
- Install the eSIM: Tap “Install eSIM” inside the app. The app will guide you through the process, setting up the configuration profile automatically.
- Activate Before Leaving: Enable the eSIM line in your phone’s network settings. We recommend doing this while still connected to your home Wi-Fi.
- Turn on Roaming: When you arrive, set your Cellular Data to Saily and ensure Data Roaming is turned on for the Saily profile. You will connect automatically.
8. Mobile Hotspot and Tethering Features
One of Saily’s biggest operational advantages over unlimited data providers like Holafly is that mobile hotspot sharing and data tethering are fully allowed on all plans. Saily does not impose speed limits, extra activation fees, or restriction blocks when you share your internet connection with other devices.
- Ideal for Remote Work: This makes Saily an outstanding option for digital nomads, business travelers, and students who need to connect their laptop, tablet, or work computer to their phone’s cellular network while traveling.
- Tethering Freedom: You can easily share your active data bucket with family members or travel companions, allowing multiple people to stay online using a single purchased eSIM package.
- Managing Your Data Consumption: While hotspot sharing is fully supported, it is important to remember that connected devices-especially laptops running background system updates, cloud photo syncs, or video streaming-consume data significantly faster than a single mobile device. We recommend disabling automatic updates on tethered devices and monitoring your data balance inside the Saily mobile app to prevent unexpected data depletion.
9. Customer Support and Reliability
In the travel eSIM industry, customer support is a critical safety net, as network handshakes in foreign countries can occasionally require manual troubleshooting. Saily excels here by providing 24/7 live chat customer support directly accessible inside their mobile application.
- Backed by Nord Security: Because Saily is built by the creators of NordVPN, they leverage a massive, highly optimized customer service team. This ensures that users do not have to wait hours for responses; instead, they are connected to a live support agent within 2 to 5 minutes.
- In-App Live Chat: The customer service chat is integrated directly into the Saily app interface. If you face activation issues at an airport, you can chat with a technician immediately without needing to navigate email threads or web portals.
- Comprehensive Documentation: Saily provides an extensive help center library filled with visual, step-by-step guides. These articles cover essential troubleshooting topics such as setting up manual APN settings, overriding automatic carrier selection on specific phone brands, and verifying eSIM profile installation, making it simple to get back online.
10. Country-Specific Performance Highlights

| France | Orange | 5G | 58 Mbps | Excellent |
| Japan | SoftBank | 4G LTE | 40 Mbps | Very Good |
| Canada | Rogers / Bell | 5G / 4G | 65 Mbps | Excellent |

11. Is Saily Worth It for Light vs Heavy Users?
Whether Saily represents the best value for your trip depends largely on your digital habits and expected data consumption during your stay.
- For Light to Moderate Users: Saily offers unmatched value and budget efficiency. If your daily internet usage is limited to Google Maps routing, messaging family on WhatsApp, sending emails, and casual web browsing, a 3GB or 5GB plan (valid for 30 days) is more than sufficient. With prices starting under $15 for these packages, Saily is far more economical than paying for bulk unlimited plans.
- For Heavy Users and Nomads: If you plan on streaming Netflix in high definition, downloading large video files, backing up raw camera footage, or uploading gigabytes of content to social media daily, Saily’s pay-per-GB model can become expensive. Once you consume more than 15GB to 20GB on a trip, the cost of top-ups will quickly exceed the upfront price of an unlimited data eSIM. In this scenario, purchasing an unlimited plan from a provider like Holafly is a much more sensible option.
