Using your phone in Portugal
- FAO Faro
- LIS Lisbon
- OPO Porto
- FNC Funchal, Madeira
- PDL Ponta Delgada, Azores
- The Algarve
- Albufeira, Vilamoura and Lagos are well covered; quiet coves and cliff walks can be patchy.
- Lisbon
- Strong signal across the city, on the trams and on the metro.
- Porto and the Douro Valley
- Good in Porto; signal dips in the steep valley on river cruises and the train.
- Madeira
- Covered in Funchal; the levada walks pass through tunnels and valleys with no signal.
- The Azores
- Part of Portugal and the EU, served by Portuguese networks. Crater lakes and coastal paths can have gaps.
Networks our Portugal plans use: VodafoneNOS
- Portugal is in the EU, so your UK plan may already include roaming there, free or for a daily fee. Check it before you buy an eSIM.
- Driving from the Algarve into Spain, your phone switches to a Spanish network. A Portugal-only plan doesn’t cover Spain.
Going further with Three
- Spain (day trips from the Algarve to Seville and Huelva): Three charges £2.75 a day (Go Roam in Europe).
