Portugal eSIM

Portugal reaches from Lisbon and Porto down to the Algarve and out into the Atlantic, and a Portugal plan covers Madeira and the Azores too, because both are Portugal. The catch is the open land border with Spain: Spanish networks reach across it, and a Portugal plan stops working the moment your phone switches to one.

What a week of data costs in Portugal

Prices for 7 days of data, checked on 3 November 2026. British visitors spend more nights in Portugal than any other foreign visitors, and Americans are among the biggest groups too. Daily passes charge for each day you use the phone abroad, per phone.

For a family of four on Three, that's £77 for one week; on Verizon, $336. T-Mobile customers may need nothing extra, but 256 kbps after the first 5 GB is slow for maps and photos. Vodafone Portugal also sells a Portugal and Europe eSIM for €20, with unlimited data in Portugal for 15 days. Vivo's and TIM's roaming pages wouldn't load for us, so check those in your app.

If your SIM is from an EU country, it already roams like at home in Portugal, as long as you spend more time at home than abroad. Spanish, French and German visitors usually don't need us here.

Landing at Lisbon, Porto, Faro, Funchal or Ponta Delgada

Switch the kimsim line on as the plane taxis to the gate and turn on Data Roaming for that line only. Then go through passport control, collect your bags and walk out through customs. With the line already working, you can walk past the SIM counters.

At the border. Since 12 October 2025, the EU's Entry/Exit System records non-EU visitors' fingerprints and a photo, and it has been fully in place since 10 April 2026. Portuguese officers may ask for an onward or return ticket and proof you have enough money for your visit. Save those to your phone before you fly. ETIAS isn't running yet, so don't pay any website that offers one.

Into town:

• Lisbon (LIS): Aeroporto station, the end of the metro's red line, sits at the southern edge of Terminal 1 arrivals, and trains reach downtown in about 20 minutes. You can tap a contactless bank card on the gates, or buy a navegante occasional card for €0.50. A free shuttle links Terminal 2 to Terminal 1 every ten minutes, and the old Aerobus stopped in 2023.
• Porto (OPO): metro line E runs from Aeroporto station into the city; change at Trindade for other lines.
• Faro (FAO): buses 14 and 16 run daily to Faro's bus station, about 4 km away, where buses leave for the rest of the Algarve.
• Funchal, Madeira (FNC): the airport is about 13 km from Funchal, and wind limits often disrupt flights there. Keep your airline's app working on mobile data in case your flight is held or rerouted.
• Ponta Delgada, Azores (PDL): the airport on São Miguel is 2 km west of the city centre, and SATA Air Açores flies from there to Terceira, Pico, Faial (Horta), São Jorge, Santa Maria and Flores.

Networks and coverage

Portugal has four mobile networks. MEO is Altice Portugal's, and from 2025 the company has been dropping the Altice name for MEO. NOS and Vodafone are the other two long-standing networks. Digi is the newest: it bought the smaller operator Nowo in 2024 and started selling services on 4 November 2024.

This plan uses NOS and Vodafone, both with 5G, and your phone shows whichever it's on, not kimsim. Coverage is generally strong in Lisbon, Porto, the Algarve towns and along the main motorways. Expect gaps in the thinly populated interior, in mountain valleys and below the cliffs of the west coast. Download offline maps before you head inland or out on a trail.

The networks your plan uses are listed above.

Region by region

• Lisbon and Sintra: the capital and its hills, with Sintra's palaces and the Cascais coast a short train ride out.
• Porto and the Douro valley: Porto is the base for the wine quintas upriver. The valley's terraced slopes are steep, so expect weaker signal between villages.
• The Algarve: beaches, resorts and boat trips to the sea caves around Benagil. The UK Foreign Office warns that falling rocks are a hazard on Algarve cliffs, and that a red beach flag means you must not enter the water. Save directions back to the car before you walk down to a cove.
• Madeira: the levadas, old irrigation channels, run for more than 2,170 km and double as walking paths. Some routes, such as Caldeirão Verde, pass through tunnels where you need a torch, and you won't get signal inside. The Foreign Office calls hiking on Madeira and the Azores challenging, and suggests telling your hotel where you're going and taking a phone.
• The Azores: nine islands, part of Portugal and one of the EU's outermost regions, like Madeira. This plan covers them as Portugal; we haven't tested signal on each island ourselves.
• The Alentejo: wide, quiet farmland between Lisbon and the Algarve, with Évora as its main city. Download the day's route before long drives.
• Next door: for Portugal and Spain on one eSIM, the Europe plan covers both. For Spain alone, see the Spain eSIM; for a trip across to Tangier, the Morocco eSIM.

Trains, roads and island hops

• Trains: CP's Alfa Pendular is the fast tilting train linking Braga, Porto, Coimbra, Lisbon and Faro. Signal can drop in cuttings, so save your ticket in the CP app before you board.
• Driving: you must carry photo ID when you drive. Set the sat-nav before you leave, and download offline maps for the interior.
• Wildfires: the risk is higher from April to October, and roads can be closed at short notice. Call 112 if you see a fire.
• Island hops: in the Azores, most people fly between islands. Keep boarding passes in your phone's wallet, not only in an app that needs a connection.

Apps worth having

• Uber works in Lisbon, including airport pickups and a taxi option. Bolt covers Lisbon, Porto, Faro, the Algarve, Madeira and Ponta Delgada. Set accounts up at home, because sign-up can send a code by text to your usual number.
• navegante is the official app for Lisbon's public transport passes. For single metro trips, a contactless bank card on the gate is simpler.
• CP is the national rail operator's app for Alfa Pendular and other train tickets.
• Google Maps: download offline areas for Madeira, the Azores and the Douro before you go. Lisbon's hills are steeper than they look, so check the walking route.
• WhatsApp is how many holiday flats, boat-trip operators and guides message you. Keep your WhatsApp number working abroad.
• Payments: contactless card payments work widely. Some banks send a text code to approve a new device, so keep your home line on for texts.

SIM and phone rules

A Portuguese SIM card means a trip to a shop: Vodafone Portugal, for example, sells its tourist eSIM online but its SIM card only in Vodafone stores. Carry your passport if you plan to buy one. We couldn't find the exact ID rule on an official Portuguese site, so ask in the shop. A physical SIM also takes your home SIM's place in a single-SIM phone.

A travel eSIM installed at home skips the counter. It's data only, so your home number stays in the phone for calls and texts.

Common mistakes

• Crossing into Spain on a Portugal plan. Both countries are in the Schengen area, so there are no routine checks at the border, and near Valença, Elvas or the Guadiana your phone can pick a Spanish network early. How to choose a network by hand
• Leaving Data Roaming on for your home line. If your SIM is from outside the EU, that's where daily charges start. Roaming goes on for the kimsim line only. Why roaming goes on for the kimsim line only
• Starting the plan on a stop-over. If you connect through another country, keep the kimsim line off until you land in Portugal. If your plan started early
• Buying a Portugal plan for a Spain and Portugal trip. Seville and Santiago de Compostela are an easy hop from Portugal, but they're in Spain. How regional plans work
• No way to call for help. Portugal's emergency number is 112. A data-only eSIM can't dial it, so use your home line or any local phone.

How we put this page together

We checked carriers' roaming price pages, Vodafone Portugal's tourist eSIM page, Metro Lisboa's site, UK and EU government sites and the other sources noted above on 2–3 November 2026. Portugal's airport sites, T-Mobile's page and Vivo's and TIM's pages block automated checks, so airport details come from the airports' encyclopedia entries and T-Mobile's price from its search listing. We haven't measured speeds or coverage in Portugal ourselves, so coverage notes are general guidance, not a map. kimsim sells the eSIMs on this page.
