Airline Baggage Fees 2026: Who Still Flies Free
Airalo vs Holafly vs Saily: Which Travel eSIM Actually Works Abroad in 2026
Apple killed the physical SIM tray on the iPhone 18 in almost every market this year. Google followed for the Pixel 10 Pro. If you’re traveling internationally this spring or summer, you’re picking an eSIM provider whether you planned to or not.
We installed and used Airalo, Holafly, and Saily across 11 countries over the past eight months: Portugal, Japan, Thailand, Morocco, Colombia, Italy, Greece, Turkey, Vietnam, the UK, and Iceland. Delayed trains, remote villages, crowded city centers, airport arrivals at 2 AM. The full range.
Here’s what actually happened.

Airalo for flexibility and country-specific plans. Holafly if you want unlimited data and don’t care about speed dips. Saily if privacy matters or you’re on a budget.
Why This Matters Now
Booking platforms like Kayak and Booking.com started bundling eSIM offers into confirmation emails in late 2025. Airline apps push them during check-in. The eSIM market went from niche tech to something your parents encounter when booking a beach vacation.
But bundled eSIMs from booking platforms are almost always overpriced. A 3GB plan bundled with a Booking.com reservation in our testing cost $22. The same coverage from Airalo was $9. Don’t buy the upsell. Pick your own provider.
Airalo: The Reliable Middle Ground
Best for: Frequent travelers who visit different regions and want granular control over data amounts.
Airalo has the widest selection of country-specific plans. Japan alone had 14 options when we checked, ranging from 1GB for $4.50 to 20GB for $26. That flexibility is the main draw.
What worked
Speed was consistently good. We hit 40–80 Mbps in Lisbon, Tokyo, and London. Rural areas dropped to 5–15 Mbps but stayed usable for maps and messaging. Video calls worked in every city we tested.
The app lets you buy and install an eSIM before your trip, then activate it on arrival. You can hold multiple eSIMs simultaneously, which is useful for multi-country trips where a regional plan doesn’t make sense.
Top-up worked mid-trip without issues. Ran out of data in Marrakech, bought 2GB more from the hotel WiFi, activated in under a minute.
What didn’t work
The “Discover” global plans are worse value than country-specific ones. A 5GB global plan costs $37. A 5GB Japan plan costs $16. If you know where you’re going, skip global.
Customer support responses took 6–18 hours via email. The in-app chat is a bot that redirects to email. If something breaks at the airport, you’re on your own.
Offline setup: You can download the eSIM profile over WiFi before departure, but activation requires a data connection. So you need airport WiFi or your home carrier’s roaming for the initial handshake. Plan for this. It takes 30 seconds but you do need signal.
Privacy
Airalo collects email, device info, and payment data. Their privacy policy allows sharing with “partners” for marketing. No VPN included. Location data collection is vague in their terms. Not the worst, not great.
Holafly: Unlimited Data, With Caveats
Best for: Heavy data users on shorter trips who don’t want to think about gigabyte limits.
Holafly’s pitch is simple: unlimited data in 170+ countries. No caps, no worrying. And it mostly delivers — with some significant asterisks.
What worked
We streamed music all day in Athens, used Google Maps constantly in Istanbul, and video-called home from a Thai island. Never hit a hard data wall. For travelers who use their phone as their primary navigation, translation, and communication tool, the peace of mind is real.
Setup was straightforward. Scan a QR code, toggle the eSIM on when you land. The app walks you through it with device-specific screenshots.
What didn’t work
“Unlimited” comes with speed management. After roughly 500MB in a short window, speeds dropped from 30 Mbps to 3–5 Mbps in our testing. Enough for maps and WhatsApp. Not enough for video calls or uploading photos. The throttling reset after a few hours, but it happened repeatedly in heavy-use days.
No hotspot/tethering. This is the dealbreaker for many. If you travel with a laptop or tablet that relies on your phone’s hotspot, Holafly won’t work. They block tethering on most plans. We confirmed this in six countries.
Pricing is higher than competitors for equivalent use. A 7-day unlimited plan for Japan costs $27. If you’d only use 4–5GB (which covers most travelers), Airalo or Saily saves you $10–15.
Offline setup: The QR code requires an internet connection to scan and download the profile. You can do this at home before departure. But if you lose the QR code email and you’re already abroad without data, you’re stuck. Save it offline or screenshot it.
Privacy
Holafly’s privacy practices gave us the most concern. The app requests location permissions that aren’t necessary for eSIM functionality. Their terms reference data sharing with advertising partners. The app includes third-party trackers (we verified with Exodus Privacy). If you care about data minimization, this is a red flag.
Saily: The Privacy-First Newcomer
Best for: Privacy-conscious travelers and budget trips where you just need maps, messaging, and basic browsing.
Saily launched in 2024, built by the team behind NordVPN. The privacy angle is their differentiator, and they back it up.
What worked
Cheapest per-GB pricing in our testing. A 5GB, 7-day plan for most European countries runs $8–10. Southeast Asia is even cheaper. For a two-week trip where you mainly use data for offline maps and messaging, a $14 plan covers it.
The NordVPN connection means built-in VPN protection on every plan. This matters when you’re connecting through foreign networks or using public WiFi in airports. The VPN activates automatically. No separate app needed.
Offline setup is genuinely offline. You download the eSIM profile at home, and it installs locally. No activation handshake needed on arrival. Turn off your home carrier, turn on the Saily eSIM, and it connects. We tested this landing in Hanoi at 1 AM with no airport WiFi and it worked immediately. This is a real advantage over Airalo and Holafly.
What didn’t work
Country coverage is thinner than competitors. We couldn’t find a plan for Morocco or Iceland. Airalo had both. Saily is strong in Europe and Southeast Asia, weaker in Africa and South America.
Speed averaged 20–40 Mbps in cities, fine for everything except large uploads. Rural Vietnam dropped to 2–3 Mbps. Usable but slow.
No unlimited option. If you burn through data streaming video, you’ll need top-ups. But top-ups are cheap ($3–5 for 1–2GB).
The app is newer and occasionally buggy. We had one failed installation in Colombia that required deleting and re-adding the profile. Took 10 minutes, but annoying when you just landed.
Privacy
This is where Saily stands apart. Minimal data collection — email and payment info only. No third-party trackers in the app. Built-in VPN encrypts traffic by default. No advertising data sharing in their terms. If you’re traveling through countries with heavy internet surveillance, this combination matters. Exodus Privacy confirmed zero trackers in the Android app.
The Offline Setup Problem (and How to Solve It)
All three apps claim easy setup, but the reality depends on your phone and your timing. Here’s the actual process:
Before you leave home (do this on WiFi):
- Check your phone supports eSIM. iPhones from the XS onward, most Android flagships from 2020+.
- Make sure your phone is carrier-unlocked. Locked phones from some carriers won’t accept third-party eSIMs. Call your carrier if unsure.
- Download your chosen app and purchase the plan.
- Install the eSIM profile. This downloads configuration data to your phone.
- Don’t activate yet. Label it in your phone settings so you can find it later. On iPhone: Settings > Cellular > your new eSIM > add a label like “Japan Trip.”
- Screenshot or save your confirmation/QR code offline. If the app crashes or logs you out abroad, you need this.
When you arrive:
- Go to Settings > Cellular (iPhone) or Settings > Network (Android).
- Enable the travel eSIM line.
- Disable your home carrier’s data roaming (unless you want surprise charges).
- Wait 10–30 seconds for connection.
If it doesn’t connect: Toggle airplane mode on, wait 5 seconds, toggle off. This forces a network scan. Worked every time for us.
Pro tip: If you’re on a multi-stop trip, buy your next country’s eSIM while you still have data in the current country. We learned this the hard way arriving in Morocco from Portugal with no plan purchased and no airport WiFi.
Real Cost Breakdown: A Two-Week Europe Trip
Here’s what each provider would cost for a 14-day trip hitting Portugal, Italy, and Greece (moderate use: maps, messaging, light browsing, some video calls):
| Provider | Plan type | Data | Cost |
|---|---|---|---|
| Airalo | Europe regional, 5GB | 5GB | $18 |
| Airalo | Europe regional, 10GB | 10GB | $32 |
| Holafly | Europe unlimited, 15 days | Unlimited* | $47 |
| Saily | Europe, 5GB | 5GB | $12 |
| Saily | Europe, 10GB | 10GB | $22 |
*Holafly’s unlimited comes with the speed throttling mentioned above.
Most travelers on a two-week trip use 4–8GB if they download offline maps ahead of time and use hotel WiFi for large uploads. The 5GB Saily plan at $12 is hard to beat if you’re disciplined. The 10GB Airalo plan at $32 gives more headroom without throttling.
Holafly’s $47 unlimited only makes sense if you refuse to connect to any WiFi and stream constantly. That’s a specific traveler, and if it’s you, it works. But most people overpay with Holafly.
Which eSIM for Which Trip Type
Weekend city break (3–5 days, one country): Saily. Cheapest, fastest setup, sufficient data. A 3GB plan runs $5–7 and covers a long weekend easily.
Two-week multi-country vacation: Airalo regional plan. Better value than Holafly’s unlimited for most usage patterns, and the flexibility to top up if you need more.
Month-long backpacking: Airalo country-specific plans, bought as you go. Regional plans get expensive for 30 days. Buy per-country, top up as needed. Budget $30–50 total.
Business travel with heavy video calls: Holafly unlimited, despite the throttling. The peace of mind matters when you can’t risk running out of data before a client call. Just know video quality might dip.
Privacy-sensitive destinations (countries with internet monitoring): Saily. The built-in VPN is the difference. Airalo and Holafly route your traffic through local carriers with no encryption layer.
Families with multiple devices: None of these are ideal. Holafly blocks tethering. You’d need separate eSIMs per device or a portable WiFi hotspot, which is a different solution entirely.
What About Your Carrier’s International Plan?
Quick comparison: T-Mobile’s international roaming gives you unlimited 2G-speed data (128 Kbps) free and charges $5/day for high-speed. AT&T’s International Day Pass is $12/day. Verizon’s TravelPass is $10/day.
A 14-day trip on AT&T’s plan: $168. On Saily: $12. The math isn’t close.
Carrier plans only make sense for trips under 3 days where you don’t want to bother with eSIM setup. Anything longer, a travel eSIM saves serious money.
If you’re already comparing flight booking tools and planning your packing, adding eSIM setup to your pre-trip checklist takes five minutes and saves $50–150 per trip.
The Verdict
Airalo is the all-rounder. Widest coverage, flexible plans, decent prices, reliable speeds. It’s the default recommendation for most international travelers.
Holafly solves a specific anxiety — running out of data. If that thought stresses you out, the unlimited plan is worth the premium and the speed compromises. Skip it if you’re comfortable monitoring usage.
Saily wins on price and privacy. If you’re budget-conscious, traveling to well-covered regions (Europe, Southeast Asia), or care about data minimization, it’s the best option. The offline setup alone puts it ahead for travelers arriving late at night in unfamiliar airports.
All three beat your carrier’s international plan by a wide margin. The real mistake isn’t picking the “wrong” eSIM; it’s paying AT&T $12/day because you didn’t spend five minutes setting one up before you left.
Set it up the night before. You’ll thank yourself at baggage claim.
