The Ultimate Guide to Staying Connected Abroad: eSIM vs. SIM Cards

Planning an international trip is exciting—but figuring out how to stay connected while abroad? That can feel a little overwhelming. The good news is, you’ve got great options for staying online, navigating maps, checking in to flights, or just keeping in touch with loved ones.

In this guide, we’ll break down the key differences between traditional SIM cards and eSIMs to help you choose the best travel connectivity solution for your next adventure.

What Is a Travel SIM?

A travel SIM card is a physical card that you insert into your phone to connect to a local network while you’re overseas. It’s a tried-and-true option that travellers have relied on for years. Most travel SIMs come preloaded with data, and in some cases, they include local calling and texting too.

Pro Tip: If your phone is unlocked and the SIM supports your device, a travel SIM can be a straightforward option—just insert it and you’re ready to go. However, some SIM cards may require manual setup or activation.

What’s an eSIM?

eSIM stands for “embedded SIM.” Instead of swapping physical cards, you can download a SIM profile digitally to your phone. No shipping, no plastic, no hassle. All you need is a compatible device and an internet connection to activate it.

eSIMs are gaining popularity fast—and for good reason. You can install multiple eSIMs on one phone, switch between them easily, and keep your original SIM active for calls or OTPs (great for banking apps!).

Which One Should You Choose?

Both options can work well, depending on your travel style, destination, and phone compatibility. Here’s a quick breakdown to help you decide:

When to Choose eSIM:

• You're travelling soon and need instant activation
• You don’t want to wait for shipping
• Your phone supports eSIM (like iPhone XS or later, Samsung Galaxy S20+, Pixel 3 and up)
• You’re hopping between multiple countries and need flexible plans

When to Go with a SIM Card:

• Your phone doesn't support eSIM
• You want a simple option without downloading anything
• You prefer the feel of a physical SIM you can swap easily
• You want a backup for emergencies
