Now let’s take a closer look at how Airalo and GigSky performed during my own international trips.

What Is an eSIM?

An eSIM is a digital SIM that’s built into your phone, allowing you to activate a mobile data plan without inserting a physical SIM card. While both companies offer digital data plans for international travel, there are a few important differences in pricing, convenience, and features that are worth considering.

I’ve now used physical SIM cards, my carrier’s international plan, Airalo, and GigSky while traveling abroad. After a few frustrating experiences with traditional SIM cards, I switched to eSIMs and haven’t looked back.

My Experience with Airalo

Airalo was the first eSIM I used while traveling internationally, and it completely changed the way I stayed connected abroad. Before that, I’d dealt with the hassle of buying physical SIM cards after landing, so being able to purchase a plan before my trip felt like a huge improvement.

The Airalo app makes it easy to browse eSIMs by destination before your trip.

Before my flight, I downloaded the Airalo app and purchased my data plan while I was waiting at the airport in the US. Then, after landing, I simply changed a few settings on my phone to activate the eSIM. I was connected within minutes without having to search for a phone store, swap SIM cards, or figure out a local carrier.

Overall, I remember Airalo being reliable and easy to use. I don’t recall having any significant issues with coverage or speed, and it did exactly what I needed it to do during my trip.

The biggest drawback I remember was having to keep track of my data plan. At some point during my travels, I needed to purchase another plan, and while the process itself was simple, I found it a little tedious to keep checking my remaining data and buying additional plans when needed. Since Airalo offers fixed data plans with set validity periods, it’s something you’ll want to keep in mind when deciding which plan to purchase.

What I Liked

  • Easy to purchase before leaving home.
  • Quick setup and activation after landing.
  • Reliable coverage during my trip.
  • Much more convenient than buying a physical SIM card.
  • Affordable plans for many destinations.

Airalo also has a loyalty program called Airmoney, where you earn cashback toward future eSIM purchases.

What I Didn’t Like

  • I found myself needing to purchase another plan during my trip.
  • I had to pay closer attention to my remaining data than I would have liked.
  • Each new trip requires purchasing a new plan and installing a new eSIM profile.

Overall, Airalo gave me a great first experience with eSIMs and showed me how much easier international travel could be without physical SIM cards. While I’ve since found some features I prefer in GigSky, I’d still recommend Airalo to travelers looking for an affordable and easy-to-use option, especially for shorter trips to a single country.

My Experience with GigSky

Before my trip to England, GigSky had actually reached out and invited me to try their service. I downloaded the app and even set up a US eSIM to explore how it worked, but I never ended up using it at home.

Before leaving for England, I reinstalled the app and planned to choose a data plan once I arrived. While I was standing in baggage claim at Heathrow Airport, I opened the app to see what was available and discovered that my Chase Sapphire Preferred® card qualified for two free promotions in the UK: a 15-day 1 GB plan and a 3-day unlimited plan.

Since I wasn’t sure how much data I’d need during my trip, I activated both offers right away. I was concerned that 1 GB might not be enough for two weeks abroad. As it turned out, I ended up using much less mobile data than I expected because I connected to WiFi at my hotels and many attractions. Looking back, I probably could have waited to activate the 3-day unlimited plan until I actually needed it.

Setup was quick and straightforward. Once I activated the eSIM, I was connected within minutes and had reliable service throughout my time in England. I used it for maps, web searches, messaging, and other everyday travel needs without any memorable issues.

One feature I especially appreciated was GigSky’s reusable eSIM. Rather than installing a brand-new eSIM profile for every trip, you simply keep the same eSIM on your phone and purchase a new data plan through the app whenever you travel to another destination. That made the whole experience feel simple and seamless.

What I Liked

  • Quick and easy setup.
  • Reliable coverage throughout my trip to England.
  • Excellent free promotions through my Chase Sapphire Preferred card.
  • Reusable eSIM for future trips.
  • Easy to purchase and manage plans in the app.
  • Cruise and inflight connectivity options for travelers who need them.

What I Didn’t Like

  • Standard plans can be more expensive than some competitors.
  • Some of the best promotions depend on your destination or eligible credit card.

Overall, GigSky gave me an excellent experience in England and has become my preferred eSIM provider for international travel. While Airalo remains a great option, especially for travelers looking for lower-priced plans, I really appreciated GigSky’s convenience, reusable eSIM, and the value I received through its promotional offers.

Airalo vs. GigSky: Which Should You Choose?

✅ Choose Airalo if…

✔️ You’re looking for the most affordable option.

✔️ You’re traveling to a single country.

✔️ You don’t mind purchasing a new eSIM for each trip.

✔️ You want one of the largest selections of country plans.

✅ Choose GigSky if…

✔️ You travel internationally more than occasionally.

✔️ You like the convenience of a reusable eSIM.

✔️ You’re taking a cruise or want inflight connectivity.

✔️ You qualify for one of GigSky’s free promotions through a credit card or other partner.

Which was easier to install?

Honestly, I found both apps easy to install and activate. I downloaded each app before my trip, purchased a plan, and was connected within minutes after arriving. The biggest difference is that Airalo typically requires a new eSIM profile for each trip, while GigSky lets you keep the same eSIM and simply purchase another plan.

Which had better coverage?

Both worked well during my travels, and I didn’t experience any major connectivity issues with either provider. Your experience may vary depending on the country and local carrier, but both gave me reliable service when I needed it.

Which offered better value?

If you’re paying full price, Airalo will often be the better value for budget travelers. However, GigSky’s promotions can completely change the equation. Thanks to my Chase Sapphire Preferred card, I was able to use GigSky for free during my trip to England, making it the clear winner in that situation.

My Recommendation

After using both services, I’d happily recommend either one. If keeping costs as low as possible is your priority, Airalo is an excellent choice. Personally, though, GigSky has become my preferred eSIM because I like its reusable eSIM, straightforward setup, and the promotions that made my most recent trip incredibly affordable.

Tips for Using an eSIM Abroad

Before you purchase an eSIM for your next international trip, here are a few things to keep in mind:

📱 Make Sure Your Phone Is eSIM Compatible

Not every phone supports eSIM technology. Most newer iPhones, Google Pixel phones, and many Samsung Galaxy devices do, but it’s worth checking your model before purchasing a plan.

🔓 Check That Your Phone Is Unlocked

Even if your phone supports eSIMs, it also needs to be carrier unlocked. If your phone is locked to your mobile carrier, you may not be able to activate an eSIM from another provider. You can usually check this in your phone’s settings or by contacting your carrier.

✈️ Install Your eSIM Before You Travel

I like downloading the app and purchasing my plan before leaving home. That way, everything is ready to go, and I only need to activate the eSIM after arriving at my destination.

📶 Keep an Eye on Your Data Usage

If you’re using a limited data plan, check your usage occasionally through the provider’s app. Connecting to hotel or café WiFi whenever it’s available can help your data last longer.

🗺️ Download Offline Maps

Before your trip, download offline maps in Google Maps (or your preferred navigation app). They’ll still work even if you temporarily lose your data connection.

📞 Know What Your Plan Includes

Most travel eSIMs are data-only, meaning they don’t include a local phone number for calls or text messages. Apps like WhatsApp, FaceTime, Messenger, and Signal are great alternatives for staying in touch over data or WiFi.

Final Verdict: Airalo vs. GigSky

If you skipped to the end looking for the short answer, here’s my take:

Ease of Use⭐⭐⭐⭐☆⭐⭐⭐⭐⭐
Overall⭐⭐⭐⭐☆⭐⭐⭐⭐⭐

*GigSky earned slightly lower marks for regular pricing, but the free promotions available through my Chase Sapphire Preferred card made it an incredible value on my trip to England.

Airalo was my introduction to eSIMs, and I’d still recommend it to travelers looking for an affordable option, especially if you’re visiting a single country and want to keep costs low.

That said, after using both providers, GigSky has become my personal favorite. I appreciated its reusable eSIM, smooth setup, reliable service in England, and the fact that I was able to take advantage of two free promotional plans through my Chase Sapphire Preferred card.

At the end of the day, I don’t think you can go wrong with either option. Both were far easier and more convenient than dealing with physical SIM cards or expensive international phone plans. The best choice really depends on your travel style, destination, and budget.
