The Big Picture
Roaming charges are a relic of the past, yet millions of travelers still get burned by them every year. The solution is clear: eSIMs. They're not just cheaper—they're smarter. But with two heavyweights, Saily and Airalo, dominating the market, the real question is which one deserves a spot on your next trip.
Let's cut through the noise. Both Saily and Airalo offer coverage in over 200 countries, both let you choose country-specific, regional, or global plans, and both are dramatically more affordable than what your carrier will charge you. But the differences run deeper than price tags. Saily, backed by the Nord Security team, brings a suite of privacy tools that Airalo simply doesn't match. Airalo, on the other hand, offers something Saily doesn't: plans with actual phone numbers and voice minutes.
This isn't a matter of which is "better" in a vacuum. It's about what fits your travel style. If you're a digital nomad who lives on data, privacy, and streaming, Saily is the obvious choice. If you're a more traditional traveler who still wants to make local calls or send SMS without juggling multiple apps, Airalo has your back. But for the vast majority of travelers, one of these will clearly outperform the other.
Key Insights
**Pricing: Saily is generally cheaper, but not by much.**
For a one-week trip to Spain, a 1 GB plan costs about $4 on Airalo and just over $3 on Saily with a discount. That's a dollar difference, but it adds up if you're traveling for a month or buying multiple plans for a family. Saily's base pricing tends to be slightly lower across most destinations, and their regular discount codes make the gap even wider. However, the difference is rarely a dealbreaker unless you're on a razor-thin budget.
**Data usage is higher than you think.**
Most travelers underestimate how much data they burn. Google Maps uses 3–20 MB per hour. Netflix in HD? 50 MB per minute. An hour of TikTok or Instagram Reels can chew through a full gigabyte. That means a 1 GB plan might last a light user a week, but a heavy user could drain it in an afternoon. Both Saily and Airalo let you top up, but Saily's ad blocker can reduce data consumption by up to 28%, which is a game-changer for small packages.
**Security: Saily wins hands down.**
Saily's Ultra plan includes the full Nord security suite—NordVPN, NordPass, and even VIP airport lounge access. But even the standard Saily plan comes with a built-in ad blocker, web protection against phishing sites, and a virtual location feature that masks your IP. These aren't gimmicks. When you're connecting to airport Wi-Fi, hotel networks, or public hotspots, having a layer of protection is critical. Airalo offers none of this. It's a pure data service, no frills.
**Airalo's one advantage: calls and texts.**
In some countries, Airalo offers plans that include a local phone number with voice minutes and SMS. This is genuinely useful if you need to call a local restaurant, a taxi service, or a hotel that doesn't use WhatsApp. Saily doesn't offer this at all. If you're the kind of traveler who still picks up the phone, Airalo is your only option here.
Practical Application
**For the budget-conscious traveler: Choose Saily.**
If your main concern is saving money and stretching your data, Saily is the smarter pick. The ad blocker alone can save you nearly a third of your data, which means you can buy a smaller, cheaper plan and still get the same usage. Plus, the virtual location feature lets you access your home streaming libraries while abroad—no more geo-blocked Netflix errors.
**For the business traveler: Choose Airalo.**
If you need to make calls, receive SMS for two-factor authentication, or have a local number for client meetings, Airalo's call-and-text plans are worth the premium. Just be aware that these plans cost more than pure data plans, so factor that into your budget.
**For the security-conscious traveler: Choose Saily.**
If you frequently use public Wi-Fi, work remotely from cafes, or handle sensitive information on the road, Saily's built-in VPN and web protection are non-negotiable. You'd otherwise need to buy a separate VPN subscription, which adds cost and complexity.
**Setup is nearly identical for both.**
Both apps guide you through installation in a few minutes. You buy a plan, scan a QR code or install the eSIM profile, and you're connected as soon as you land. I've used both extensively, and connection times are comparable—usually within a couple of minutes after touchdown.
What to Watch Out For
**Don't assume all plans are created equal.**
Airalo's pricing varies wildly by country. A 1 GB plan in Japan might cost $5, but in Nigeria, it could be $20. Saily's pricing is generally more consistent, but you should always check both before buying. Never assume one is cheaper everywhere.
**The "global" plans are not truly global.**
Both Saily and Airalo offer global plans that cover 200+ countries, but they often throttle speeds or exclude certain regions. Always read the fine print. If you're traveling to a niche destination, double-check coverage before you leave.
**Data-only plans can be limiting.**
If you rely on WhatsApp or FaceTime for calls, a data-only eSIM is fine. But if you need to call a number that doesn't use VoIP, you'll be stuck. Airalo's call-and-text plans solve this, but they're not available in every country.
**Discount codes expire.**
Both services offer discount codes, but they often have expiration dates or usage limits. Always apply the code at checkout and confirm the discount before paying.
Expert Perspective
After testing both Saily and Airalo across multiple continents, my recommendation is clear: **Saily is the better choice for 80% of travelers.** The combination of lower pricing, built-in security features, and data-saving ad blocking makes it the more complete package. The only scenario where Airalo wins is if you absolutely need a local phone number for calls and texts.
But let's be honest—how often do you actually make voice calls while traveling? Most of us rely on WhatsApp, Telegram, or FaceTime. For the rare occasion you need to call a hotel or restaurant, you can use Google Voice or Skype for pennies. The need for a traditional phone number is shrinking every year.
That said, Airalo is still a solid product. It's reliable, easy to use, and has been around longer. If you're already an Airalo user and it works for you, there's no urgent reason to switch. But if you're choosing for the first time, start with Saily.
Actionable Takeaways
1. **Buy your eSIM before you travel.** Activate it at home so it's ready to go the moment you land. Both apps allow this.
2. **Use discount codes every time.** I've linked both Saily and Airalo discounts in the description. Never pay full price.
3. **Choose a plan that matches your data habits.** If you're a heavy streamer, buy a 5 GB or 10 GB plan. If you're just checking maps and messages, 1 GB is enough for a week.
4. **For security, pick Saily.** The ad blocker and IP masking are worth the switch alone.
5. **For calls, pick Airalo.** But only if you truly need voice minutes. Otherwise, stick with data-only.
6. **Top up before you run out.** Both apps let you add data instantly. Don't wait until you're stranded without maps.
Stop overpaying for roaming. The eSIM revolution is here, and it's cheaper, faster, and more secure than ever. Choose wisely, and your next trip will be smoother from the moment you step off the plane.
