NOS Portugal SIM Card: Your Guide to Data Plans and Coverage

You land at Lisbon airport after a long flight. Your phone shows no signal, the Bolt app will not load, and your hotel wants a check-in message you cannot send. Roaming from outside the EU can turn a simple trip into an expensive one. A local SIM or eSIM fixes this for the price of a few coffees. This guide covers the NOS Portugal SIM card: what it costs, how to activate it, where the signal is strong, and how it compares with the other two big operators.

The Three Operators at a Glance

Portugal’s mobile market is dominated by three operators: NOS, Vodafone Portugal and MEO. All three run solid 4G networks and a fast-growing 5G network. For visitors, prepaid SIM cards or eSIMs are the easiest option because you get data, calls and SMS with no long contract.

• NOS (www.nos.pt) is known for competitive data plans.
• Vodafone Portugal (www.vodafone.pt) is known for good coverage.
• MEO (www.meo.pt) is the largest operator and grew out of Portugal Telecom.

Prices and data allowances are close between the three. The choice often comes down to which shop is nearest when you arrive and which app you find easiest to use.

NOS Kanguru Livre: Plans, Data and What to Expect

The tourist-friendly prepaid line from NOS is Kanguru Livre (Tourist Edition). The SIM card itself costs around €15–€20 and often comes with an initial data bundle. On top of that you choose a data bundle:

• Kanguru Livre 10GB: approximately €15 for 10GB of data, valid for 15–30 days. It includes free calls and SMS to other NOS numbers.
• Kanguru Livre 20GB: approximately €20–€25 for 20GB of data, valid for 30 days. It also includes free calls and SMS to other NOS numbers.

These plans are built around data. International calls are usually charged separately or need a specific add-on. Most visitors use WhatsApp, FaceTime or similar apps for home calls, so this rarely matters. Before you pay, ask the shop assistant to confirm the exact validity period and what calls and SMS are included, because bundle details can change from one year to the next.

For comparison, Vodafone’s Go plans and MEO’s TOP plans sit in a similar range. Vodafone Go 10GB and MEO TOP 10GB are both about €15, and the 20GB versions are about €20–€25. Vodafone’s bundle includes unlimited calls and SMS to national networks, and MEO’s includes some national calls and SMS. If you plan to phone local restaurants, taxi drivers or hosts on different networks, that national calling can be useful.

Physical SIM or eSIM: Choosing the Right Format

A physical SIM suits you if your phone does not support eSIM, or if you like handling everything face to face. A store visit takes about 5–15 minutes, depending on the queue. An eSIM suits you if your phone supports it and you want to skip the shop. Activation online is usually instant after purchase.

All three operators are expected to offer eSIMs for prepaid plans by 2026, and NOS is expected to roll them out more widely. The cost is similar to a physical SIM, often with an initial data bundle included. Data-only SIMs are less common for tourists, but the prepaid plans above work as data SIMs for most visitors.

How to Buy and Activate a NOS SIM in a Store

NOS shops (Lojas NOS) are found in shopping centres, major cities and airports, including Lisbon, Porto and Faro. You can also buy from authorised resellers and kiosks. Here is the process:

1. Bring your passport. A valid passport or an EU/EEA national ID card is mandatory for SIM registration in Portugal. This is Portuguese law.
2. Choose your bundle. Tell the assistant whether you want 10GB or 20GB and how long you are staying.
3. Register. The assistant registers the SIM in your name.
4. Insert the SIM. It should activate automatically within minutes. You may receive a confirmation SMS.

How to Set Up a NOS eSIM Online

If your phone supports eSIM, you can skip the shop entirely:

1. Go to www.nos.pt and choose a prepaid eSIM plan.
2. Enter your passport details during the purchase. Registration is required.
3. Pay online. A QR code arrives by email.
4. Scan the QR code with your eSIM-compatible phone. The line then activates.

NOS can also deliver a physical SIM to a Portuguese address if you order online. This helps if you already have a hotel or rental booked and want the SIM waiting for you.

Topping Up and Checking Your Balance

Topping up (carregamentos) is simple, and it works the same way with all three operators. For NOS you have four options:

• My NOS app: available on iOS and Android. Register your number and pay with a credit or debit card.
• NOS stores: pay in person with cash or card.
• Multibanco ATMs: choose “Telemóveis”, then “NOS”, then enter your number and the amount.
• Online: go to www.nos.pt/carregamentos.

Vodafone has the My Vodafone app and www.vodafone.pt/carregamentos. MEO has the My MEO app and www.meo.pt/carregamentos. Both also use the “Telemóveis” menu on Multibanco ATMs.

To check your remaining balance and data, open the operator’s app or dial a short code such as *#123#. Check it every few days so you do not run out of data in the middle of a day trip.

Coverage Across Mainland Portugal, the Azores and Madeira

Portugal has generally excellent mobile coverage, especially 4G in urban areas and along major transport routes.

Mainland Portugal

• Cities: Lisbon, Porto, Braga, Coimbra, Faro and other cities have near-universal 4G and 5G coverage.
• Highways: the A1 (Lisbon–Porto), A2 (Lisbon–Algarve) and A4 (Porto–Bragança) generally have strong, consistent coverage.
• Rural areas: coverage can be spotty or drop to 3G or 2G in very remote, mountainous or sparsely populated regions. Download offline maps before you head into the hills.

Azores and Madeira

• Main towns: good 4G and 5G in Funchal (Madeira), Ponta Delgada (São Miguel, Azores), Angra do Heroísmo (Terceira, Azores) and other main towns.
• Coastal areas: generally good.
• Mountains and remote areas: coverage can be intermittent, especially in deep valleys and volcanic regions.

On a hiking day in the Azores or on a levada walk in Madeira, expect the signal to come and go. Save your route offline and tell someone where you are going.

Staying Connected on Trains and Buses

On CP (Comboios de Portugal) intercity and regional routes, coverage is generally good. Tunnels and very rural stretches can cause drops, and some newer trains may offer onboard WiFi. On Rede Expressos long-distance coaches, coverage is usually reliable along major routes, and onboard WiFi is increasingly common.

If you plan to work from a seat, download your files and maps before you board. A short tunnel will not matter, but a long rural stretch might.

WiFi in Cafes, Hotels and Public Spaces

WiFi can cut your data use sharply. It is not a full replacement for a SIM, though.

• Cafes and restaurants: free WiFi is widely available, especially in tourist areas. Look for “Wi-Fi Grátis” signs. Ask for the password when you order your espresso.
• Accommodation: hotels, hostels, guesthouses and rental apartments almost universally offer free WiFi to guests.
• Public WiFi: limited but growing in major city centres, public squares and transport hubs. Speed and quality vary.

EU Roaming Rules: Do You Even Need a Portuguese SIM?

EU/EEA citizens: under the “Roam Like At Home” regulation, you can use your home country’s mobile plan in Portugal at no extra cost. Your home data, calls and SMS allowances apply. A Portuguese SIM is optional for you.

Visitors from outside the EU/EEA: “Roam Like At Home” does not apply to you. Buying a local Portuguese SIM or eSIM is significantly more cost-effective than international roaming with your home provider.

Your Portuguese prepaid SIM will also work under “Roam Like At Home” rules if you travel to other EU/EEA countries. A fair-usage policy typically applies, so a portion of your national data allowance may be capped for EU roaming. The cap is usually generous for tourist needs. Ask your operator for the exact roaming data limit on your plan before you cross a border.

2026 Budget Reality

The figures below are approximate and based on projected 2026 pricing. Confirm the final price in the shop or app before you pay.

• Budget: a Vodafone or MEO SIM at around €10–€15, plus a 10GB bundle at about €15. This suits a short trip with lots of WiFi use.
• Mid-range: a NOS Kanguru Livre SIM at around €15–€20, plus the 10GB bundle at about €15. This suits a week or two of normal maps, messaging and social media use.
• Comfortable: a NOS, Vodafone or MEO 20GB bundle at around €20–€25 on top of the SIM card. This suits longer stays, remote work, video calls and hotspotting.

The SIM card often includes an initial data bundle or credit, so your first-day cost may be lower than the sum of the two parts. Compare that with a single day of non-EU roaming fees from your home provider, and a local SIM pays for itself quickly.

What Has Changed Since 2024

• More eSIM options: the biggest change by 2026 is the expected wider availability and easier activation of eSIMs for prepaid plans across all three major operators. You are less likely to need a shop on arrival.
• Small price changes: minor increases of €1–€2 per bundle are possible because of inflation and network investment. Competition should keep prices fairly stable.
• More data: a €15 plan might offer 12GB instead of 10GB, as operators compete.
• Wider 5G: 5G should be significantly more widespread across mainland Portugal and in key areas of the Azores and Madeira, with faster speeds.
• More self-service: managing plans, topping up and getting support through operator apps and websites is becoming the norm.
• Plan name changes: no major prepaid options are expected to end, but older, less data-rich plans may be phased out in favour of bigger data bundles. Plan names can change, so the shop or website may show a slightly different name from the one you read here.

Common Mistakes to Avoid

• Arriving without your passport: registration is mandatory by law. A photo on your phone may not be enough.
• Assuming calls are included internationally: NOS plans are data-focused. Free calls and SMS usually apply to other NOS numbers, and international calls are normally charged separately or need an add-on.
• Ignoring the validity period: a 10GB bundle can be valid for 15–30 days. If you stay longer, plan your top-up.
• Using home roaming from outside the EU: “Roam Like At Home” does not cover you, so check your plan before you land.
• Waiting until the last minute to buy an eSIM: set it up where you have WiFi, not when you are already standing in a queue with no signal.
• Counting on mobile data in remote areas: signal can drop to 3G or 2G in very remote mainland regions and in mountainous parts of the islands.
• Forgetting EU fair-usage limits: your Portuguese SIM may have a cap on EU roaming data if you travel to Spain, France or elsewhere.

Frequently Asked Questions

Do I need a passport to buy a NOS SIM card in Portugal?

Yes. A valid passport or an EU/EEA national ID card is mandatory for all SIM registrations in Portugal under Portuguese law. The store assistant registers the SIM in your name. For an online eSIM, you enter your passport details during the purchase process instead.

How much does a NOS prepaid SIM cost for tourists in 2026?

The NOS Kanguru Livre SIM card costs around €15–€20, often with an initial data bundle. A 10GB bundle is approximately €15, and a 20GB bundle is approximately €20–€25. Prices are projected for 2026, so confirm the final price in the shop or app.

Can I get a NOS eSIM instead of a physical SIM?

Yes, NOS is expected to offer eSIMs more widely for prepaid plans by 2026. You buy online at www.nos.pt, provide your passport details, receive a QR code by email, and scan it with an eSIM-compatible phone. Activation is usually instant after purchase.

Does NOS work in the Azores and Madeira?

Coverage is good in main towns such as Funchal, Ponta Delgada and Angra do Heroísmo, with 4G and 5G in key areas. Coastal areas are generally good. Mountainous and remote areas, especially deep valleys and volcanic regions, can have intermittent signal, so save offline maps for hikes.

Will my phone plan work in Portugal without a local SIM?

If you are from an EU/EEA country, your home plan works at no extra cost under “Roam Like At Home”. If you are from outside the EU/EEA, those rules do not apply. A local Portuguese SIM or eSIM is significantly cheaper than international roaming for those visitors.
