Planning an international trip? One of the first things you’ll need after booking your flights and accommodation is a reliable internet connection.
Gone are the days of searching for local SIM card kiosks or paying expensive roaming fees. Travel eSIMs have made it possible to get online the moment you land.
After testing multiple providers across Europe, Asia, and North America, Airalo remains our top pick for most travelers. With coverage in 200+ destinations, affordable pricing, and an easy setup process, it’s the most reliable all-around eSIM for the vast majority of international trips. To understand the vision behind this game-changing tech, you can read more about Airalo’s global mission and background.
Here’s why Airalo deserves a spot on your phone before your next adventure.
What Is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Instead of inserting a physical SIM card, you simply download an eSIM profile and activate it in a few minutes.
With an eSIM, you can:
- Get connected before your flight lands
- Avoid expensive roaming charges
- Keep your home SIM active for calls and SMS
- Use multiple mobile plans on one device
- Switch between countries without changing SIM cards
If you are new to this technology, you can explore this official, step-by-step guide on how Airalo works to keep you connected effortlessly.

Airalo & Travel eSIMs: Real Questions, Honest Answers
When we first started using eSIMs, we had a ton of skeptical questions. Here are the exact things we wondered about—and what we’ve learned after miles on the road.
Will I lose my regular WhatsApp, FaceTime, or iMessage history?
Absolutely not. This is the biggest fear people have, and the answer is a relieving no. Your WhatsApp and iMessage are tied to your account/iCloud, not your data connection. When you activate Airalo, all your chats, groups, and contact lists stay exactly the same. You can text your friends back home on WhatsApp just like you never left.
Do I get a local phone number to make traditional phone calls?
Most Airalo plans are data-only, meaning they do not come with a local phone number for traditional voice calls or texts. Honestly? In 2026, you rarely need one. We use WhatsApp, FaceTime, Google Voice, or Skype to call hotels, restaurants, or Ubers using our Airalo data. If you absolutely need a local number, Airalo does offer a few specific “Discover” global plans that include calling features—just check the plan details before buying.
Is Airalo difficult to set up?
Not at all. Installation usually takes less than five minutes. Most travelers can purchase and install their eSIM before departure and activate it as soon as they land.
Is Airalo worth it for short trips?
Definitely. If you’re taking a weekend city break or a one- or two-week vacation, Airalo is often one of the most cost-effective and convenient ways to stay connected.
Who shouldn’t use Airalo?
If you’re staying in one country for several months and need unlimited data or a local phone number, a local carrier SIM may offer better value. For most tourists and frequent travelers, however, Airalo is an excellent choice.
