Portugal has strong 4G/5G coverage across Lisbon, Porto, the Algarve, and Madeira. It is one of Europe's most affordable eSIM destinations and a great base for exploring with mobile data in hand.
Yes. The Algarve has excellent coverage including remote beaches and coastal roads. Madeira has good 4G in Funchal and main towns, with slightly weaker coverage in the mountainous interior. The Azores has improving but patchier coverage.
If you are visiting only Portugal, a country-specific plan gives you the best GB-per-dollar ratio. For a combined Iberian trip, a Spain+Portugal or full European multi-country plan typically works out cheaper overall — compare live options on Farelah.
Lisbon's tram routes and hilly streets make Google Maps and transport apps indispensable. A week of regular map use, social media, and WhatsApp consumes around 3–5 GB. The city's cafe Wi-Fi is generally reliable as a supplement.
