Using an eSIM in Portugal
Portugal is one of Europe’s most digital nomad-friendly countries. With coworking spaces and surf spots across the country, it’s no surprise that remote workers love to travel to Lisbon, Porto, and the Algarve, not to mention smaller hotspots like Ericeira for surfing.
Whether you're watching the waves in Nazaré, coworking in Lisbon, or wandering through Porto’s historic alleys, having mobile data is essential for navigating through the country, booking taxis, or calling your family from a beautiful beach. If you don’t want to waste time at airport kiosks or local stores, getting an eSIM before you arrive is the best move you can make.
I’ll admit: I didn’t use eSIMs at all during my first year as a digital nomad. But once I tried one, I never went back to physical SIM cards.
In this guide, you’ll find our top 3 eSIM recommendations for Portugal, plus a directory to compare even more options. Every provider listed here has been tested and vetted with digital nomads in mind.
What is an eSIM, and why use one in Portugal?

Why eSIMs are great for Portugal
✅ No need to find a phone shop or kiosk
✅ Set up before your flight
