Best eSIM for Digital Nomads & Expats: How to Keep Your Home Number Abroad

For digital nomads, remote workers, and serial expats, reliable internet is not a luxury—it is the foundation of your livelihood. Whether you are running an e-commerce business from a cafe in Lisbon, taking Zoom calls from a co-working space in Cape Town, or finalizing your corporate expansion in London, losing connectivity means losing income.

Historically, the nomadic lifestyle required a frustrating ritual: landing in a new country, hunting down a local telecom shop, fumbling with a SIM ejector tool, and taping your tiny home SIM card to the inside of your phone case so you wouldn't lose it.

The advent of the eSIM has completely revolutionized remote work. By transitioning to a digital SIM, you can cross borders seamlessly without ever losing a signal.

How Does Airalo Work?

An eSIM (embedded SIM) is a tiny microchip already built into the motherboard of most modern smartphones (including recent iPhones, Samsung Galaxies, and Google Pixels). Instead of inserting a physical plastic card to connect to a network, you simply download a digital "profile."

Airalo is the world’s leading marketplace for these digital profiles. Here is the exact process of how Airalo works for expats:

1. Browse the App: Open the Airalo app and search for your destination country or region.

2. Select a Data Pack: Choose a prepaid data allowance (e.g., 10GB for 30 days) that fits your remote work needs.

3. Install Digitally: Scan a QR code or follow the in-app prompts to install the digital profile into your phone’s settings.

4. Connect Instantly: When you arrive in your new country, toggle the Airalo line "on." Your phone will instantly ping the local cell towers, giving you high-speed 4G or 5G data before you even disembark the plane.

Keeping Your Home Number While Living Abroad With eSIM

One of the most significant challenges for expats is getting locked out of their home bank accounts. Almost all modern financial institutions require Two-Factor Authentication (2FA) sent via SMS to your registered home phone number. If you remove your home physical SIM card to use a local one, you cannot receive these critical security codes.

Airalo solves this through Dual-SIM functionality.

Because the Airalo data pack is entirely digital, your physical home SIM card stays safely inside your phone. You simply go into your smartphone's settings and configure your connections:

• Default Voice/SMS Line: Set to your Home Provider (to receive incoming texts, WhatsApp messages, and 2FA codes).

• Default Cellular Data Line: Set to Airalo (so all your internet browsing, video calls, and social media run on the cheap, localized data plan).

This setup ensures you remain fully accessible to clients and banks back home while entirely avoiding exorbitant international data roaming charges.

Airalo Review 2026: The Best eSIM for Digital Nomads

When evaluating the best eSIM for digital nomads, flexibility and coverage are the deciding factors. While competitors like Holafly offer unlimited data, they frequently block mobile hotspot tethering. If the Wi-Fi drops at your Airbnb and you need to tether your laptop to your phone to finish a client presentation, a tethering restriction is catastrophic.

Airalo allows mobile hotspot tethering on the vast majority of its plans. Furthermore, Airalo offers tailored packages for the nomadic lifestyle:

• Local eSIMs: For expats settling in a single country for a long-term visa.

• Regional eSIMs: For nomads traveling across borders (e.g., the Eurolink eSIM covers 39 European countries, allowing you to take a train from France to Germany without ever changing your data plan).

• Global eSIMs: The ultimate tool for frequent flyers, covering up to 130 countries on a single digital profile.
