If you’ve ever arrived in a new country and suddenly lost mobile data, you know how frustrating it can be. Whether it’s trying to book a ride, check into your Airbnb, or pull up Google Maps — reliable internet is essential when you’re abroad.
For years, travelers dealt with roaming charges, confusing SIM card kiosks, and unpredictable Wi-Fi. But now, there’s a simpler solution that’s changing the way people stay connected while traveling: eSIMs.
In this guide, I’ll break down:
- What an eSIM is and how it works
- The best eSIM options for international travel in 2025
- How to set it up on your phone
- Real-world use cases (plus what to watch out for)
What Is an eSIM and Why Do Travelers Use It?
An eSIM (short for “embedded SIM”) is a digital version of the SIM card that’s already built into your smartphone. Instead of physically swapping out SIM cards when you land in a new country, you can just install a mobile data plan online and activate it in minutes.
This means:
- No waiting in line at airports
- No need to carry or swap tiny plastic SIM cards
- No worrying about losing your original SIM
Common Situations Where eSIMs Help:
- You land at an airport and need a ride right away
- You’re country-hopping and don’t want a new SIM for every place
- You want to avoid $15/day roaming fees from your regular carrier
- You’re working remotely and need constant, stable data
eSIMs give you the flexibility to stay online without disruption — and many people use them alongside their regular SIM for calls and messages.
Does Your Phone Support eSIMs?
Before diving in, check if your phone supports eSIM functionality. Most phones from the last few years do.
Phones that support eSIM:
- iPhone XR and newer (including SE 2nd/3rd gen)
- Google Pixel 3 and newer
- Samsung Galaxy S20/S21/S22/S23 series
- Many newer Motorola and Huawei models
You can confirm in your phone settings:
- iPhone: Settings → Cellular → Add Cellular Plan
- Android: Settings → Network & Internet → Mobile Network → Add Operator
Best eSIM Providers for International Travel (2025 Edition)
There are several eSIM providers available, each offering different strengths. I spent time comparing a few based on coverage, ease of use, and cost. Here’s what stood out:
1. Airalo – Best for Budget Travelers and Frequent Flyers
Airalo is widely used for its broad country coverage and affordable local plans. You can buy data packages for a single country, a region (like Europe or Asia), or even a global plan if you’re visiting multiple continents.
Key features:
- Plans available in over 200 countries
- Pricing starts as low as $4.50
- Easy to install via QR code or app
- Great for short trips and light data usage
A common use case is grabbing a 3GB Europe plan for under $15 to cover a 2-week trip.
Many travelers choose Airalo as their first eSIM because the setup is easy and the data plans are straightforward.
2. Holafly – Great for Heavy Data Users and Remote Workers
Holafly is slightly different in that it often offers unlimited data plans, especially useful for people who stream, hotspot, or work remotely while abroad.
Key features:
- Unlimited data in many popular destinations
- Best suited for longer stays or heavier use
- Setup via QR code or app, similar to Airalo
- 24/7 live support (nice if you run into issues abroad)
One thing to note: some of Holafly’s plans don’t allow hotspot tethering, so it’s worth double-checking before buying if you plan to share data with a laptop or other device.
Holafly tends to appeal more to digital nomads or business travelers who need to stay connected around the clock.

3. Nomad eSIM – Another Easy-to-Use Option for Mainstream Travelers
Nomad is another travel eSIM platform that offers competitive rates and an intuitive app interface. While not as widely known as Airalo or Holafly, it’s still a solid option worth checking.
- Regional and global plans
- Comparable pricing
- Clean mobile interface
- Not as robust in support or unlimited options
You can compare Nomad’s rates too, especially if you’re visiting only a couple of countries.
How to Set Up an eSIM (Step-by-Step)
Setting up your eSIM is surprisingly simple. Here’s a quick walkthrough that applies to most providers:
✅ Step 1: Buy Your Plan Online
Choose your destination and select a plan that matches your travel dates and data needs.
✅ Step 2: Install the eSIM
After purchase, you’ll get a QR code (or manual activation code).
Go to:
- iPhone: Settings → Cellular → Add eSIM
- Android: Settings → Network → Add eSIM or SIM profile
✅ Step 3: Turn It On When You Arrive
Most providers let you install ahead of time and only activate when you land. That way, you’re instantly online once your plane touches down.
❓ Common Questions Travelers Have About eSIMs
Can I still use my phone number with an eSIM?
Yes. Most phones allow dual SIM functionality — meaning your regular SIM handles calls/texts, and your eSIM handles data.
Can I keep my eSIM active across multiple countries?
Yes — if you choose a regional or global plan (offered by Airalo and Holafly), you don’t need to switch eSIMs when crossing borders.
Is an eSIM more secure than public Wi-Fi?
Definitely. Using mobile data (via eSIM) is safer than relying on open Wi-Fi networks, especially for checking emails, banking, or logging into apps.
Pros and Cons
🧭 My Final Tip for First-Time Users
If you’re using an eSIM for the first time, I recommend starting with a short plan from a provider like Airalo. Their smaller data packages are affordable, and the app guides you through the setup clearly.
Even if you only need 1–2GB for maps and messaging, it’s better than searching for SIM cards or asking strangers for Wi-Fi passwords.

🎒 Final Thoughts: Travel Smarter, Stay Connected
Traveling today is easier than ever — but staying connected can still be stressful if you’re not prepared. eSIMs help eliminate that stress, giving you control, security, and flexibility wherever you go.
Whether you’re planning a short city break or a month-long backpacking trip, getting your data plan sorted before you fly makes everything smoother.
And the best part? You don’t need to be tech-savvy. You just need a phone that supports eSIM and a few minutes to set it up.
