Step 1: Check if Your Phone is eSIM Compatible
Most smartphones manufactured since 2018 are eSIM compatible. This includes iPhone XS and newer, Google Pixel 3 and newer, and high-end Samsung Galaxy models. You can check your phone’s settings or use the compatibility checker on the provider’s website.

This is where the magic happens. After comparing the options, our clear recommendation for most travelers is Airalo. Here’s how to get your plan.
On their site, you can choose a plan for a single country, a region (like Europe), or even a global plan. Select the data package that fits your needs, pay online, and Airalo will immediately provide a QR code.
Step 3: Install and Activate Your eSIM
This part seems technical, but it’s surprisingly simple. Just before you leave, while you have Wi-Fi, go to your phone’s cellular settings and choose “Add eSIM.” Scan the QR code from your Airalo app or email and follow the on-screen prompts. When you land, just turn on your eSIM line, and you’ll be online instantly. You have now mastered the basics of international connectivity.

Total Cost: ~$25
Cash Savings: ~$75. For a small amount of prep work, you achieve massive savings on your international connectivity.
Gotchas You Shouldn’t Ignore
- Most eSIMs are Data-Only: A key detail for any eSIM for beginners guide is that the majority of tourist eSIM plans do not come with a local phone number. This means you can’t make or receive traditional calls or SMS texts. However, you can still use services like WhatsApp, FaceTime Audio, and Skype perfectly over your data connection.
- One-Time Install: A QR code is typically for a one-time installation. Once you activate it, you cannot move it to another phone. If you delete the eSIM from your phone, you will likely lose the plan.
- Check Top-Up Rules: Some cheaper, obscure eSIMs don’t allow you to add more data once you run out. This is a major reason we recommend a service like Airalo, which makes it easy to top up your plan directly from their app.

FAQs About eSIMs and International Connectivity
Can I use my regular SIM and an eSIM at the same time?
Yes! This is one of the biggest advantages. You can keep your primary SIM active to receive calls and texts on your regular phone number while using the cheaper eSIM for all your mobile data. This dual-SIM capability is a game-changer for international connectivity.
Do I keep my primary phone number (like for WhatsApp) with an eSIM?
Yes. Apps like WhatsApp, iMessage, and Telegram are tied to your phone number, not your SIM card’s data plan. When you activate your eSIM for data, WhatsApp will ask if you want to keep your original number. Simply select “yes,” and everything will work exactly as it did before.
What happens if I run out of data on my eSIM plan?
This is a key advantage of using a quality provider. With a service like our recommended partner, Airalo, you can easily “top up” and buy more data directly from their app. It’s a simple process that takes just a minute and ensures your international connectivity is never interrupted.
