Connection to Internet

Most cafés and accommodations offer free WiFi; however, it’s still a good idea to have your own connection. After trying different providers, I found Vodafone to be the most reliable. At the airport, there is a Vodafone kiosk where you can buy a physical SIM (usually more expensive than e-sim. Last time it was unlimited data for €20 for 20 days) or an eSIM. Note: prices could change.

The best deal (as of March, 2026) I’ve found so far was purchasing an eSIM (Vodafone) through the TAP Air Portugal app, it was around €15 for 30 days. 

MEO is good for rural  areas and road trips.

NOS -is best for in the big cities like Lisbon, Porto, Coimbra, etc.

Please note the U.S.-based companies such as Verizon, AT&T, and even T-Mobile are not good choices for mobile data use in Portugal. Service is typically expensive and may offer slower connections with frequent interruptions.
