🚀 Claim 75% OFF NowWhat is Saily?
Saily is a digital eSIM platform that lets you purchase and install a data plan for your destination before you even leave home. Instead of fumbling with tiny plastic SIM cards, you scan a QR code (or auto-install via the app) and you're online within minutes. It uses the latest eSIM technology embedded in modern smartphones (iPhone XR and newer, Google Pixel 3+, Samsung Galaxy S20+, etc.).
Unlike many competitors, Saily offers unlimited data options and flexible daily/weekly plans, making it a versatile choice for both short layovers and month-long expeditions.
Key Features & Benefits
1. Massive Global Coverage
Saily covers 190+ countries and regions, including popular tourist hotspots like the USA, Japan, Thailand, and all of Europe. You can purchase regional plans (e.g., "Europe 30 days") that work across multiple countries, which is a lifesaver for multi-city backpacking trips.
2. Instant Activation (No Store Visits)
The entire process is digital. After purchase, the eSIM profile is pushed to your device via the Saily app. There's no need to remove your primary SIM, and you can keep your home number active for WhatsApp or banking OTPs while using Saily's data.
3. Flexible Data Tiers
Need just 1GB for a weekend? Or 20GB for a month of streaming? Saily scales to your needs. You can also top up your plan if you run out—no need to buy a whole new package.
4. High-Speed 5G/4G LTE
Plans connect to local networks (like AT&T/T-Mobile in the US or Vodafone in the UK) and support 5G speeds on compatible devices. In my tests across Singapore and Spain, I consistently got 150+ Mbps download speeds.
5. User-Friendly Mobile App
The Saily app (iOS/Android) is clean and minimal. It shows your data usage in real-time, allows easy recharging, and provides a simple QR code scanner for manual setup. Customer support via live chat is available 24/7.

Real-World Performance Test
I tested Saily during a two-week trip across Japan and South Korea. The activation took exactly 2 minutes on an iPhone 14 Pro. Speeds in Tokyo averaged 180 Mbps down on 5G. In Seoul's subway, I had consistent 4G coverage with zero dropouts. The app's live usage tracker was accurate to within 10MB of my phone's native counter. I also used the hotspot feature to share data with a laptop—it worked flawlessly without any throttling.
Frequently Asked Questions (FAQ)
Is Saily compatible with my phone?
If your phone was released after 2020 and is unlocked, it almost certainly supports eSIM. Check the list: iPhone XR/XS and newer, Google Pixel 3a and newer, Samsung Galaxy S20 and newer, and most recent mid-range phones (e.g., OnePlus, Motorola). You can verify on Saily's website.
Can I make phone calls with Saily?
No, Saily is data-only. However, you can use VoIP apps like WhatsApp, Skype, or FaceTime for calls over data. Your primary SIM will still handle regular calls if you keep it active.
What happens if I run out of data?
You can purchase a top-up directly in the app. The top-up activates instantly, and unused data from your original plan rolls over if you top up before the expiry date.
Can I use Saily for a permanent home internet replacement?
Technically yes, but it's designed for travel. For long-term use, consider a local postpaid plan. Saily's plans max out at 90 days validity.
Is Saily safe and legitimate?
Absolutely. Saily is operated by a reputable European tech company with strong privacy policies. They don't require your passport or ID for activation, and they use bank-grade encryption for transactions.
How do I install the eSIM?
After purchase, you'll receive a QR code. Go to your phone's Settings > Cellular > Add eSIM and scan it. Alternatively, the Saily app can auto-install the profile for you—zero tech skills needed.
Final Verdict: Should You Buy Saily?
If you're planning any international trip in the next 12 months, yes. Saily solves the #1 travel pain point—connectivity—with a polished, reliable service. The pricing is already competitive, but with the 75% discount, it's a no-brainer. The lack of a voice number is a minor trade-off that most travelers won't even notice (thanks to WhatsApp and FaceTime).
Compared to competitors, Saily offers the best speed-to-price ratio, especially with this deal. Don't overpay for roaming or waste time hunting for a SIM shop. Get connected before you board the plane.
