## Portugal: what to know before you land

Source: https://viasimo.com/destinations/portugal/#destination-guide · Researched October 2026 by Viasimo

Portugal switched off its last 3G networks in 2024. Your eSIM uses NOS and Vodafone, so outside 5G areas your phone runs on 4G. The 28 April 2025 Iberian blackout knocked out mobile data across the mainland for hours, and in summer wildfire alerts matter, so 112 and the Visit Madeira and Visit Azores trail-closure pages are worth knowing.

### Portugal: quick facts

| Fact | Portugal |
| --- | --- |
| Emergency number | 112 |
| Main airports | Lisbon Humberto Delgado Airport (LIS); Porto Francisco Sá Carneiro Airport (OPO); Faro Airport (FAO); Madeira Cristiano Ronaldo International Airport (FNC); João Paulo II Airport, Ponta Delgada (PDL) |
| Plug types | Type C, F (230V) |

### MEO, NOS, Vodafone and Portugal's 2024 3G switch-off

(Portugal · https://viasimo.com/destinations/portugal/#guide-meo-nos-vodafone-and-portugal-s-2024-3g-switch-off)

Portugal has three established networks: **MEO**, **NOS** and **Vodafone**. The Romanian group **DIGI** has also been expanding into the market. Your eSIM uses **NOS** and **Vodafone**, so you won't see MEO or DIGI selected even when they appear in your phone's network list.

All three established operators retired 3G during 2024. MEO went first on 31 January, NOS followed on 31 May, and Vodafone finished on 31 July. Phones in Portugal now use 4G across most of the country, with 5G in the larger cities. Where 4G fades, in a Douro gorge, a Madeira levada tunnel or on an Azores crater rim, you won't drop to a slower 3G signal. You'll more likely lose data altogether until you climb back into range.

If you're visiting on an EU plan, Portugal is in the EU, so standard EU roaming rules usually apply to your home SIM. Check with your operator. For travellers from the UK, the US or elsewhere, the eSIM gives you local data without relying on your home operator's roaming terms.

### Lessons from the 28 April 2025 Iberian blackout

(Portugal · https://viasimo.com/destinations/portugal/#guide-lessons-from-the-28-april-2025-iberian-blackout)

At 11:33 local time on **28 April 2025**, the electricity grids of mainland Portugal and Spain collapsed. Shops, supermarkets and pharmacies stopped trading, card payments failed, and traffic lights and urban rail went dark. **Mobile networks were badly limited for both calls and data.** Lisbon airport closed early in the afternoon and didn't restart flights until about 21:40. Porto and Faro switched to generators. About half of Portugal had power again by 22:30, and the grid was fully restored early the next day.

The Portuguese government has since announced a €400 million programme to strengthen the grid, and the European grid body ENTSO-E traced the cause to voltage control. The day showed how much a trip depends on power and data.

Keep a little euro cash for when card terminals fail, save your hotel address and return booking for offline use, and carry a charged power bank. If mobile data goes down, Wi-Fi in a hotel with backup power may still work.

### Wildfire season, red beach flags and calling 112

(Portugal · https://viasimo.com/destinations/portugal/#guide-wildfire-season-red-beach-flags-and-calling-112)

Portugal's single emergency number is **112**. The UK government says wildfire risk is highest from **April to October**. It advises checking the fire risk index for the area you're in, following the authorities' instructions, and calling 112 if you see a fire. **Starting a fire is illegal, even by accident**, so take particular care with barbecues and cigarettes in the Algarve hills and on the interior roads. Check the risk index on your phone each morning, along with any road closures, before you drive into forested areas.

On the coast, read the **beach flags**. A **red flag** means you must not go in the water, and a **yellow flag** means paddling at the edge only. If you're caught in a rip current, swim parallel to the shore until you're out of it, then head in.

On **Madeira** and in the **Azores**, the UK government suggests checking path closures on the official **Visit Madeira** and **Visit Azores** websites before setting out, leaving your route with hotel reception, carrying a phone and walking with a group or a guide. Trails can close after storms or rockfalls, so check on the day.

## Seven days in Portugal: Lisbon, Sintra, Coimbra, Porto and the Douro Valley

7-day itinerary · 7 days · Source: https://viasimo.com/destinations/portugal/#itinerary

A rail-based first week from south to north: Lisbon's old quarters and Belém, the palaces of Sintra, a stop at Coimbra's historic university, then Porto and a day up the Douro line among the port vineyards. No car needed.

**When to go:** April to June and September to October are warm without the peak heat and crowds of July and August; the Douro harvest runs from about mid-September, and wildfire risk is highest from April to October.

### Day 1 in Portugal: Lisbon: Alfama, the castle and Baixa

- **Base:** Lisbon
- **Getting there:** From Lisbon airport, the metro red line reaches the centre in about 25 minutes with one change.
- **Plan:** Ride tram 28 or walk up into Alfama and climb to the Castelo de São Jorge for the view over the Tagus. Wander down the lanes past the Sé cathedral and the Miradouro de Santa Luzia, then cross into the Baixa grid rebuilt after the 1755 earthquake, finishing at the Praça do Comércio on the river. In the evening go up to Bairro Alto or hear fado back in Alfama.
- **Mobile signal:** Central Lisbon has NOS and Vodafone 5G; the metro has signal in stations, and the narrow Alfama lanes can briefly drop to weaker 4G.

### Day 2 in Portugal: Belém and the riverside

- **Base:** Lisbon
- **Getting there:** Tram 15 or the Cascais line train reach Belém in about 20–25 minutes from the centre.
- **Plan:** Take the tram or train west to Belém and visit the Jerónimos Monastery, with its carved Manueline cloister, then walk to the Padrão dos Descobrimentos and the Belém Tower on the river. Try a pastel de Belém from the original bakery. In the afternoon visit the MAAT museum on the waterfront, or return to the centre for the LX Factory in Alcântara and sunset at the Miradouro de São Pedro de Alcântara.
- **Mobile signal:** Strong 5G along the Belém waterfront and on the Cascais line.

### Day 3 in Portugal: Sintra's palaces

- **Base:** Lisbon
- **Getting there:** About 40 minutes by train from Lisbon Rossio to Sintra; the 434 bus loops up to Pena and the Moorish Castle.
- **Plan:** Take an early train to Sintra and go straight up to the Pena Palace, the brightly painted Romantic castle built for Ferdinand II, before the crowds; book a timed ticket in advance. Walk down through the Pena Park to the Moorish Castle walls on the ridge, then visit Quinta da Regaleira, with its initiation well and grottoes, or Monserrate Palace and its gardens. Return to Lisbon in the evening.
- **Mobile signal:** 4G is good in Sintra town; coverage weakens in the wooded hills of the Pena Park and inside the castle walls and Regaleira's tunnels.

### Day 4 in Portugal: Coimbra's university and on to Porto

- **Base:** Porto
- **Getting there:** About 1 hour 40 minutes by Alfa Pendular or Intercidades from Lisbon to Coimbra-B, then about 1 hour to Porto Campanhã.
- **Plan:** Take the train north to Coimbra and walk up to the university on its hilltop, part of a UNESCO site, to see the Joanine Library, the baroque book hall, and the Royal Palace rooms and tower. Walk down through the old town past the Sé Velha to the Santa Cruz Monastery, then continue by train to Porto and walk down from São Bento station, with its blue-and-white tiled hall, to the river.
- **Mobile signal:** The Lisbon–Porto main line has 4G nearly all the way, with short drops in cuttings; Coimbra and Porto have 5G in the centre.

### Day 5 in Portugal: Porto: Ribeira, the Dom Luís I Bridge and Gaia

- **Base:** Porto
- **Getting there:** Everything is walkable, though Porto is steep; metro line D crosses the upper bridge deck.
- **Plan:** Climb the Clérigos Tower for the view over the rooftops, then look at the tiled Igreja do Carmo and the Livraria Lello bookshop, booking ahead. Walk down to the Ribeira waterfront and cross the upper deck of the Dom Luís I Bridge to Vila Nova de Gaia, where you can tour a port lodge and taste. Ride the Gaia cable car down to the riverside or take a short boat trip under Porto's bridges.
- **Mobile signal:** Strong 5G across central Porto and Gaia; inside the port lodges' stone cellars signal can drop away.

### Day 6 in Portugal: The Douro line to Pinhão

- **Base:** Porto
- **Getting there:** About 2.5 hours each way by regional train from Porto São Bento to Pinhão; trains are not frequent, so check times in the CP app.
- **Plan:** Take the regional train up the Douro line, which follows the river for much of the way past Régua into the terraced vineyards of the Alto Douro Wine Region. Get off at Pinhão, whose station is decorated with tiles showing the harvest, and visit a quinta for a tasting, or take a short boat trip on the river. Return to Porto on an afternoon train.
- **Mobile signal:** 4G is decent in Régua and Pinhão, but the line through the steeper gorges and tunnels has gaps, and some vineyard estates up the slopes have weak coverage.

### Day 7 in Portugal: Serralves, Foz do Douro and departure

- **Base:** Porto
- **Getting there:** Serralves is about 20 minutes by bus from the centre; the metro purple line reaches Porto airport in about 30 minutes.
- **Plan:** Visit the Serralves Foundation, with its contemporary art museum and Art Deco villa set in large gardens. Take tram 1 or walk along the river to Foz do Douro, where the Douro meets the Atlantic, and walk the seafront to the Felgueiras lighthouse before heading to the airport for your flight.
- **Mobile signal:** Good 5G at Serralves, Foz and on the metro to the airport.

### Staying connected on this Portugal route

- Book Pena Palace and Livraria Lello tickets on your phone in advance; timed slots sell out in summer.
- Check Douro line train times in the CP app the day before, and download an offline map of the valley for the gaps between Régua and Pinhão.
- Keep a little cash and a charged power bank: the April 2025 Iberian blackout showed how quickly card payments and mobile data can fail.
- Portugal has no 3G any more, so a weak spot means waiting for 4G rather than a slower fallback.

## About this eSIM

Portugal is really three trips sharing one country code: the mainland, Madeira, and the Azores. The mainland is easy and densely covered. The islands are fine where people live and abruptly empty where they hike, which is where you will be spending your time. An eSIM handles all three under one line, so the only thing you need to think about is which parts of the map deserve an offline download.

### Getting online when you land

Load the profile before you fly and switch it on at the gate. Lisbon's airport sits inside the city, so you can be in a taxi within minutes of clearing passport control, and being connected before that is worth doing. Porto and Faro are similar; Funchal in Madeira takes a little longer to register on arrival but gets there.

The reason to have it live immediately is the ride apps. They operate at all the main Portuguese airports, the pickup zones are marked in the app rather than obviously signposted, and it is a much cheaper and calmer way into town than the rank. In Lisbon, the metro from the airport is the other good option and its ticketing and times are easiest to sort with data in hand.

### The networks you'll be on

Your data rides on whichever of NOS or Vodafone has the better signal, both covering 4G LTE and 5G. The 5G layer turns up around Lisbon, Porto and other larger centres; LTE is what carries the rest of the country and it is genuinely good. Video calls from a café in Alfama or Ribeira will be unremarkable, which is the highest compliment you can pay a network.

On the islands the same technologies apply but the geography argues with them. Madeira and the Azores are volcanic, steep and full of tunnels, so what you experience is less about the speed tier and more about whether a ridge is standing between you and a mast.

### Where coverage holds, and where it thins

Lisbon and Porto are covered end to end, including the metro systems and the trams. The Algarve coast from Faro through Lagos is strong all summer, and the A1 and A2 motorways connecting the country hold signal for the whole drive. Coimbra, Évora, Braga and the smaller cities are all fine.

The mainland's thin spots are interior and upland. The Alentejo away from the towns has long quiet stretches, the Serra da Estrela loses signal on the higher roads, and Peneda Gerês national park is patchy once you are off the main routes. The Douro valley is a special case: the river bends between steep terraced walls, and coverage disappears and returns as you follow it.

Madeira is well served in Funchal and along the south coast, and much less so on the levada walks, which is precisely where you will want a map. Several levadas run through unlit tunnels with no signal at all. The Azores are connected in the main towns of each island, weaker on the crater rims, the western flanks and the inter island ferry crossings. Assume any hike above the villages on either archipelago is offline.

### What you'll actually use data for here

Getting around, mostly. Ride hailing is well established in the mainland cities, the CP rail app handles intercity tickets, and Lisbon's hills mean you will be checking which tram or funicular saves you a climb more often than you would like to admit.

Then the things that Portugal specifically rewards: surf and swell forecasts, which decide whether Nazaré or Ericeira is worth the drive that day; restaurant reservations, because the good small places fill and many take bookings by phone or message; and trail information for the levadas and the Azorean crater walks, where trails do close after rain and the notice is usually online. Add translation for menus, since fish names in Portuguese defeat most people, and photo backup, since you will take an unreasonable number of tile photographs.

### Before you fly

Install the eSIM at home and set it as your data line, keeping your usual SIM active for bank confirmations. Check the per line roaming switch is on for the travel line.

Download offline maps for every island and hiking area on your list, and save the specific levada or crater trail routes rather than relying on live navigation in a tunnel. Cache your rail and ferry bookings as images. If you are driving the Douro or crossing the Serra da Estrela, have the route saved before you start rather than after the signal goes. And on the islands, check the weather the morning of a hike instead of the night before: it changes fast, and knowing early is the whole benefit of having data at all.

## Frequently asked questions

### Does an eSIM work in Portugal?

Yes. Your Portugal eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are NOS, Vodafone. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

### Do I get 5G in Portugal?

Yes, where it has been deployed. 5G runs on NOS, Vodafone in Portugal, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

### Is there still 3G in Portugal?

No. MEO switched off 3G on 31 January 2024, NOS on 31 May 2024 and Vodafone on 31 July 2024. Phones now use 4G and, in the larger cities, 5G. Your eSIM uses NOS and Vodafone. In places 4G doesn't reach, such as deep valleys and Madeira's levada tunnels, expect no data rather than a slow 3G connection.

### Did mobile phones work during the 2025 Portugal blackout?

Only partly. During the Iberian blackout on 28 April 2025, mobile networks in Portugal were badly limited for calls and data, card payments failed and urban rail stopped. Lisbon airport closed in the afternoon and flights restarted that evening. Power was fully restored early the next day. Carry some cash and a power bank as a precaution.

### How do I check if a levada or Azores trail is closed?

The UK government recommends checking path closures on the official Visit Madeira and Visit Azores websites before you set out. Trails can close after heavy rain or rockfalls. Many walks lose signal once you're above the villages, so check on the morning of your walk, leave your route with your hotel and carry a charged phone.

### When is wildfire season in Portugal?

The UK government says wildfire risk is highest from April to October. Check the fire risk index for where you're staying, follow the authorities' advice and report any fire on 112. Starting a fire, even accidentally, is illegal in Portugal, so be especially careful with barbecues and cigarettes in rural areas.

### How much data do I need for 7 days in Portugal?

For 7 days in Portugal, Viasimo sells 1 GB for $1.59 and unlimited data for $13.99. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone.
