Who it's for: Those who want a "set it and forget it" solution with 24/7 support.

Our Rating: 4.8 / 5 ⭐⭐⭐⭐⭐
What Exactly is an eSIM? (And Why You Need One)
Before diving into Saily, let's clear up the fundamentals. An eSIM (embedded SIM) is a digital SIM card built into your phone. Instead of fumbling with a tiny plastic card, you scan a QR code or install a profile via an app. Your phone then connects to local networks in your destination country.
Why this matters for travel:
- No physical SIM hunting: Forget visiting dodgy kiosks at the airport.
- Instant activation: Buy and install before you even board the plane.
- Keep your home number active: For WhatsApp, banking OTPs, and iMessage.
- Cost savings: Usually 50-90% cheaper than traditional roaming.
Now, let's see how Saily executes this.
Saily: The Core Features & Benefits
1. Painless Installation (Step-by-Step)
Saily's biggest win is the onboarding process. Here's exactly how it works:
- Download the Saily app (iOS & Android).
- Search for your destination country or region.
- Pick a data package (1GB, 3GB, 5GB, etc.).
- Pay via Apple Pay, Google Pay, or credit card.
- Scan the QR code or tap "Install eSIM" (it takes 2 minutes).
- Activate when you land (or before, if you want to test).
My experience: I installed it in the airport lounge while sipping a coffee. The whole process took under 4 minutes, and I didn't need a Wi-Fi connection to finish the setup—the app guides you through it smoothly.
2. Global Coverage Without the Fuss
Saily covers 100+ countries and regions, including major hubs like the US, UK, Japan, Australia, and most of Europe. They use tier-1 local networks (e.g., O2, Vodafone, T-Mobile), so you're not stuck on a flaky MVNO. The app automatically connects to the strongest signal, and you can manually switch networks if needed.
3. Transparent, Pay-Only-For-Data Pricing
No hidden fees. No "fair usage" surprises. You buy a data allowance, and that's it. If you run out, you top up directly from the app. The data-only nature means no voice minutes, but for most travelers, WhatsApp and FaceTime cover that gap.
4. Hotspot Tethering Allowed
Need to use your laptop at a café? Saily allows hotspot sharing, a feature many budget eSIM providers block. This is a game-changer for remote workers.
5. 24/7 Human Support (Not Just a Bot)
I tested their support chat at 3 AM EST with a random question about APN settings. A human replied in under 90 seconds. That's rare in the eSIM world.

Saily Pricing Comparison: Is It Cheaper Than the Competition?
To give you context, here's a comparison of a 5GB data package for 30 days in the USA across popular eSIM providers:
| Provider | Price (USD) | Validity | Hotspot? |
|---|---|---|---|
| Saily | $24.99 (often discounted) | 30 days | ✅ Yes |
| Airalo | $26.00 | 30 days | ✅ Yes |
| Holafly | $34.00 | 15 days (unlimited cap) | ❌ No |
| Nomad | $23.00 | 30 days | ✅ Yes |
Prices are indicative and may vary. Saily frequently runs promotions that bring the cost down further.
The takeaway: Saily sits in the sweet spot—competitive with budget leaders but with a more polished app and better customer support. If you catch a sale (like the one linked below), it becomes the best value in the market.
How to Use Saily on Your Trip: A Step-by-Step Guide
If you're new to the eSIM game, here's the exact workflow to ensure zero headaches:
Step 1: Check Compatibility
Ensure your phone is unlocked and eSIM-compatible. Most recent iPhones (XR and newer), Google Pixels, and Samsung Galaxy S20+ (and above) work. Saily's app will check this automatically.
Step 2: Purchase Before You Fly
Buy your package while on Wi-Fi at home. This saves you from needing data to buy data. You can install the eSIM profile immediately but keep it "off" until you land.
Step 3: Enable Data Roaming
When you arrive, go to Settings → Cellular → Tap your Saily line → Enable "Data Roaming". Your phone will switch to the local network. That's it.
Step 4: Manage Your Usage
The Saily app shows real-time data usage. Set a warning threshold (e.g., 80%) to avoid running out mid-Google-Maps-navigation.
Step 5: Top Up If Needed
Out of data? Buy another package in the app. It activates within 30 seconds.
FAQ: Your Burning Questions, Answered
❓ Does Saily work in China?
Yes, Saily works in mainland China, but you'll be connected to a network that may be slower due to the Great Firewall. It's fine for messaging and maps, but don't expect lightning-fast video streaming. VPNs are not included.
❓ Can I make phone calls with Saily?
No, Saily is data-only. You cannot receive or make traditional calls. Use WhatsApp, FaceTime, or Skype instead. You can still receive SMS on your home SIM if your carrier supports Wi-Fi calling.
❓ Is Saily safe and secure?
Yes. Saily is operated by Nord Security, the company behind NordVPN. They have a strong reputation for privacy. Your data is encrypted, and they don't sell your browsing history.
❓ What if my flight is delayed or I change my itinerary?
Plans are valid for a set period (usually 30 days) from the moment of purchase, not activation. If you need to change dates, contact support—they're often flexible with adjustments.
❓ Can I share my connection with my travel partner?
Yes, you can turn on Personal Hotspot and share your Saily data with another device. This is great for splitting the cost.
❓ What happens if I run out of data?
You'll lose connection, but you can buy an instant top-up in the app. You won't be charged any overage fees.
Final Verdict: Is Saily Worth It?
Yes, unequivocally. Saily solves the #1 travel pain point—connectivity—with a frictionless app and transparent pricing. While it's not the absolute cheapest per GB (you can find local SIMs for pennies in Southeast Asia), the convenience, reliability, and support make it a no-brainer for:
- Short-haul trips (3-10 days) where hunting for a local SIM wastes precious time.
- Multi-country itineraries (Europe rail trips, Southeast Asia backpacks) where you'd otherwise buy 3 different SIMs.
- Business travelers who need guaranteed connectivity at a moment's notice.
If you're still on the fence, consider this: the cost of one missed Uber ride or a lost reservation due to no data far exceeds the $5 you might save with a sketchy provider. Saily is the premium choice at a mid-range price.
