Why go
A little preparation keeps maps, digital tickets and travel details accessible from the moment you arrive. EU roaming rules generally let eligible residents use calls, messages and data in Portugal at domestic rates, subject to fair-use limits. Travelers on other plans may find a Portuguese SIM or eSIM more economical. Free Wi-Fi is common in accommodation and many public-facing spaces, but a mobile connection remains useful on streets and between transport stops. Portugal's international calling code is +351.
Useful to know
- Check your home carrier's roaming terms before departure, especially if your plan was issued outside the EU.
- Use a local physical SIM or eSIM when it offers better value than international roaming.
- Expect Wi-Fi in many hotels, restaurants, transport hubs and other public-facing venues, but keep mobile data available for navigation.
