If you’ve ever traveled abroad, you know the feeling. You’ve packed your bags, double-checked your passport, and still forgot something. For me, that something used to be connectivity. There’s nothing worse than landing in a new country and realizing you’re stuck hunting for a local SIM—or worse, waiting in an endless airport queue to overpay for one.
Thankfully, eSIMs changed the game. No physical cards, no waiting in line. Just a quick install, and you’re connected.
Two of the biggest names in the space are Holafly and Airalo. I’ve tested both extensively—most recently on a trip to Vietnam—and while they both get the job done, their approaches couldn’t be more different. Here’s how they compare, so you can decide which one actually fits your travel style.
Holafly vs Airalo: Quick Comparison
| Feature | Holafly eSIM | Airalo eSIM |
|---|---|---|
| Data Plans | Mostly unlimited—daily, weekly, monthly options | Fixed data packages (1 GB, 5 GB, 20 GB) |
| Pricing | Higher, but reflects unlimited data | Cheaper, especially for light usage |
| Coverage | 200+ destinations | 200+ destinations |
| Unlimited Data | Yes—core feature (fair usage policy applies) | Rare, outside a few specific plans |
| Voice/SMS | Data-only (WhatsApp, FaceTime, etc.) | Some plans (Discover+) include voice/SMS in select regions |
| Hotspot/Tethering | Yes | Yes |
| App & Activation | QR code or app—simple setup | QR code or app—simple setup |
| Best For | Long trips, heavy streaming, hotspot sharing | Short trips, light or controlled data use |
Different Approaches, Different Value
The biggest difference between Holafly and Airalo comes down to how they structure their plans.
Airalo gives you fixed data buckets. If you’re just passing through France for a couple of days and only need navigation and messaging, a 1 GB plan for $4 is perfect. That kind of flexibility keeps costs low when your needs are minimal.
But here’s the catch: 1 GB or 3 GB disappears fast. The average American household uses over 600 GB a month at home. On the road, streaming YouTube in Full HD for an hour can burn through 3 GB alone. So if your trip lasts longer than a day or two, those cheap plans start adding up quickly.
Holafly flips the model entirely. Their plans are almost always unlimited. You don’t have to count megabytes, watch your video quality, or stress about running out in the middle of a train ride. Yes, it costs more upfront—usually starting around $4 per day—but for anyone who doesn’t want to think about data limits, it’s a different kind of freedom.

Global eSIM: For Frequent Travelers
If you’re someone who jumps between countries regularly, both providers offer global plans—again with very different philosophies.
- Airalo’s global plans: $13 for 1 GB over 7 days, up to $34 for 3 GB over 30 days. Need more data? You’ll pay for more.
- Holafly’s global plans: $62 for 7 days of unlimited data across 110+ countries. More expensive, but truly unlimited.
Holafly also has a subscription option covering 160+ destinations. You can cancel anytime, so it works even for shorter trips. Their Light Plan gives you 25 GB for $49.90, while the Unlimited Plan runs $64.90 per month with hotspot included.

| 30 days | Unlimited data – $224.00 | 3 GB – $34.00 |
Support & App Experience
Both Holafly and Airalo offer easy setup via QR code, manual configuration, or their apps. But the experience beyond installation differs.
Holafly shines in support. It holds a 4.6 rating on Trustpilot, with travelers consistently praising their 24/7 multilingual help. Their refund policy is also generous—up to six months after purchase. The downside? Their app can be buggy. I ran into issues with inaccurate data usage reporting and even got the dreaded “content not available in your location” error on Netflix a couple of times.
Airalo has a 3.9 rating. That’s still solid, but some users report frustrations with network coverage and support responsiveness. That said, Airalo’s app is a standout: stable, intuitive, and filled with helpful tutorials that make setup genuinely easy.
Both offer loyalty programs. Airalo gives up to 10% cashback on purchases, while Holafly offers 7%.
My Personal Experience
I put both to the test on a recent trip to Vietnam, installing them before I even left.
I grabbed Holafly’s unlimited weekly plan for $27 and Airalo’s 10 GB / 7-day plan for $16. After landing, both connected immediately—no fuss.
Over the next few days, I did my usual testing: speed checks, video downloads, and WhatsApp calls back home. Call quality was excellent on both, and navigation worked smoothly in both Saigon and the quieter beach town of Tuy Hoa. Speeds were comparable too—around 50 Mbps down, 15 Mbps up.
But the real difference showed up on a long train ride. Without Wi-Fi, I burned through Airalo’s 10 GB in just a few days. Holafly’s unlimited plan kept me going without a second thought. That peace of mind—especially in an unfamiliar place—turned out to be worth more than the price difference.
Verdict
The choice between Holafly and Airalo really comes down to how you travel.
If you want to set it and forget it—no counting gigabytes, no worrying about running out of data during a critical moment—Holafly is the better fit. It’s ideal for longer trips, heavy users, or anyone who just wants one less thing to stress about. Just keep in mind the app can be a little temperamental at times.
If you’re taking a short trip, passing through a country, or know you’ll use data sparingly, Airalo offers serious savings without sacrificing reliability. Their app experience is smoother, and the pay-as-you-go model works great when you know exactly what you need.
No matter which you choose, both are miles ahead of hunting down a physical SIM at the airport.
