Portuguese SIMs are easy enough to buy at FNAC or NOS stores but you'll pay €15-25 for tourist plans that often won't include the Azores or Madeira. A Roamgo Portugal eSIM covers mainland Portugal and both island groups at one price — no surprise roaming when you island-hop to Funchal or São Miguel.
- Best for
- Lisbon and Porto city breaks; Algarve coast holidays; surf trips along the Atlantic coast; Madeira hiking; Azores nature tours; Douro Valley wine routes.
- Networks
- Roams onto MEO, NOS, and Vodafone Portugal. MEO has the strongest reach on the islands and inland Algarve; NOS is competitive in Lisbon, Porto, and Coimbra.
- Travel tip
- Coverage on the Algarve back-country roads and in the Madeira mountain villages can drop out — load the offline Maps tile for your day's route before you leave, especially around Pico do Arieiro.
