A prepaid Portugal eSIM from eSpeedz starts at $7.99 and gives you mobile data on local networks from Lisbon and Porto down to the Algarve coast. You scan the QR code we email you before your flight, and the plan switches on the moment your phone connects in Portugal.
Tram routes, Bolt rides up from the riverfront and every pastel de nata photo you send home, all on one prepaid plan instead of a daily roaming charge.
Coming from the US, your carrier's day pass bills you for every day you use your phone abroad, and a week in Lisbon plus a few days in Porto adds up faster than you'd think. On many T-Mobile plans the included international data slows right down once the high-speed allowance runs out, which tends to happen just as you're trying to load directions through the tangle of lanes in Alfama or Ribeira. A Portugal eSIM gives you full-speed local data for the whole trip at one prepaid price.
Portugal runs on apps more than people expect. Bolt and Uber both operate legally under the country's ride-hailing rules in Lisbon, Porto, the Algarve and Madeira, and they're the easiest way back up a steep hill after dinner. Lisbon's metro, Carris buses and the old yellow trams use the Navegante card, which replaced the Viva Viagem card, though the metro also takes contactless bank cards now. Porto has its own system, the Andante card, for its metro, buses and funicular. Google Maps does the rest, and in a city built on seven hills you'll check it a lot.
Cafe and guesthouse wifi in Lisbon and Porto is generally fine for email and messaging, but it doesn't come with you on a day trip to Sintra, a drive along the Algarve cliffs or a walk through the vineyards of the Douro Valley. Having your own data means you can book a train on your phone, check when the next tram is due and translate a menu without hunting for a password.

For a week in Lisbon and Porto with maps, ride apps, messaging and a steady stream of photos, 5GB is usually plenty. If you're driving the Algarve or the Alentejo with navigation running for hours, or posting videos as you go, 10GB gives you breathing room. Two weeks, or working remotely from a Lisbon apartment with daily video calls, points to 20GB, and the 50GB plan is there if you'll tether a laptop. Every Portugal plan lasts 30 days, so you're never racing a short clock.
Spring (April to June) and early fall (September and October) are the sweet spot: warm enough for the Algarve beaches, mild for walking Lisbon's hills, and calmer than the July and August peak. Summer is hot inland but lovely on the coast. Winter is quiet and rainier in the north, while Madeira stays mild all year, which makes it a popular winter escape.
