Why Get an eSIM for Portugal?
- Online from Lisbon or Porto Airport, ready for the metro or a ride app.
- Great for digital nomads. Portugal is a favorite base for remote workers, and a hotspot-ready eSIM is a useful backup to café Wi-Fi.
- Keep your number for bank codes and messages from home.
- Avoid roaming fees if your carrier is outside the EU.
How to Choose a Portugal eSIM
Trip length
Pick a plan that covers your whole stay plus a spare day for flight times. egoViet plans can't be topped up, so it is better to size up than to run short. If your high-speed data does run out, you stay online at a basic speed of around 128 kbps, enough for messaging.
How much data you use
Maps, transport apps, and messages use little data. Video calls and hotspotting a laptop use much more. Here is a guide to how much data you need when you travel.
Where you are going
For Portugal alone, a Portugal eSIM is the best value. If you are also visiting Spain or other European countries, see the Europe eSIM below.
