How to buy a prepaid SIM card for Portugal: The complete guide

Why is it a good idea to buy a prepaid SIM card for Portugal?

When you buy a prepaid SIM card for Portugal, you’ll be able to access the internet, and depending on your plan, you may be able to make calls and send SMS texts back home. 

• Call, text, and get data on the cheap: Making calls and sending texts overseas can rack up quite the bill from your carrier. Some prepaid SIM cards give you a local phone number to make domestic calls and send texts within the country. Depending on your plan, you may also be able to make international calls and send texts from abroad.

• Avoid shockingly high roaming fees: Picture this: You’ve settled in after having the time of your life in Portugal, and you receive the notification, “You’ve incurred US$300 in international roaming charges.” If you’re out of the loop, many carriers charge a flat fee for international data usage per day. In this case, it doesn’t matter if you scroll Instagram for five minutes or three hours while you’re abroad — the cost will be the same. Most prepaid SIM cards give you much cheaper data than these carrier rates from your home country. Alternatively, if your phone supports eSIM technology, services like Saily let you activate a data plan digitally before or during your trip, helping you avoid expensive roaming charges without needing a physical SIM card.

• Stay connected across Europe: With some Portuguese SIM cards, you can use data in other European countries. If you plan on hitting other popular tourist destinations in the continent, this option may save you some money since you won’t have to buy another international SIM card. 

• Stay safe online: Did you know that hackers sometimes set up fake networks to impersonate public Wi-Fi networks so they can steal your data? Unfortunately, unsecured networks might pose real cybersecurity risks. With a Portuguese prepaid SIM card, you won’t have to resort to unsecured networks for internet access. 

Now that you know all the benefits of SIM cards, let’s take a look at three of the top Portuguese SIM card providers. 

Best tourist SIM card providers in Portugal

When searching for the best SIM card for Portugal, you’ll usually come across three major providers: MEO, Vodafone Portugal, and NOS. These are the country’s main mobile networks and the most common choices for travelers looking for prepaid data, local calls, and strong nationwide coverage. We’ll look at each of them in more detail below.

MEO: Overview and network coverage

MEO is one of the biggest and most established mobile operators in Portugal, and it’s often the first name travelers hear when searching for a SIM card. It has strong nationwide coverage, including smaller towns, rural areas, and island regions like Madeira and the Azores, which makes it a reliable pick if your trip goes beyond Lisbon and Porto. Many travelers say MEO performs especially well on road trips and in places where smaller networks can be less consistent.

The network offers 4G across most of the country, with 5G available in larger cities and many tourist areas. Real-world speeds depend on your location and time of day, but for maps, video calls, streaming, and hotspot use, MEO is usually more than enough.

One reason visitors like MEO is the range of prepaid options. Current offers include low-cost starter SIMs from around €2.50 (US$2.85) for basic prepaid cards, while data-focused plans start from around €10 (US$11.40) and go higher depending on how much data you need. If you want a provider with broad coverage and flexible prepaid choices, MEO is often a safe bet.

Vodafone Portugal: Overview and network coverage

Vodafone Portugal is a strong option for travelers who want a familiar name and dependable service. It’s one of the country’s three main mobile networks and is especially popular in cities, beach towns, and major tourist areas. If you’re staying in Lisbon, Porto, Faro, or moving between well-known destinations, Vodafone is usually a very safe choice.

Coverage is solid across most of the country, with 4G widely available and 5G in larger cities and busy travel hubs. Travelers often mention that Vodafone performs well for streaming, hotspot use, and video calls, especially in urban areas. In more remote inland spots, MEO sometimes has a slight edge, but for most typical trips the difference is small.

Vodafone’s tourist-focused prepaid offers are easy to understand, which is part of the appeal. Current options include Vodafone Travellers with 20 GB, 500 minutes/SMS, and 50 international minutes for €20 (around US$23) valid for 30 days. There is also an unlimited Portugal-only data option for €34.99 (around US$40) for 30 days. If you want simple setup, reliable speeds, and a network many international travelers already know, Vodafone Portugal is a smart pick.

NOS Portugal: Overview and network coverage

NOS is one of Portugal’s three main mobile operators and is often mentioned by travelers who care most about mobile data speeds. It has a strong presence across the country and is especially reliable in cities, coastal areas, and popular tourist destinations. If your trip is focused on Lisbon, Porto, the Algarve, or other well-visited spots, NOS is a decent choice!

Many travel forums and comparison sites note that NOS performs very well for 4G and 5G, with some ranking it among the faster mobile networks in Portugal. In day-to-day use, that means smooth navigation, video streaming, hotspot use, and quick uploads. Coverage is generally strong nationwide, though in some remote inland areas MEO can still have a slight advantage.

NOS also has competitive prepaid options. Current pay-as-you-go plans include around 10 GB with 500 minutes/SMS for €14.99 (US$17), while larger plans with 100 GB and 1200 minutes/SMS cost €19 (US$21). Monthly contract plans can include even more data, including unlimited options. If fast mobile data matters most to you, NOS is well worth considering.

UZO, Lyca Mobile, and Nowo: An overview of smaller providers

Beyond the three major networks, Portugal has a few smaller MVNOs worth a mention for travelers looking for alternatives.

UZO is a budget-friendly MVNO that runs on MEO's network, offering some of the more affordable prepaid data plans in the country, such as 40 GB for €2.50 (US$2.85)/week or 100 GB for €4 (US$4.55)/week, making it a solid pick if keeping costs low is the priority.

Lyca Mobile is the most widely used MVNO in Portugal and operates on Vodafone's network, making it especially appealing to travelers who make frequent international calls thanks to its competitive international calling rates alongside standard prepaid data options starting from around €8 (US$9).

Nowo is a smaller provider that has historically offered budget mobile plans in Portugal, though as of 2026 it is in the process of being taken over by Digi Portugal, so it is worth checking its current availability before picking up a SIM.

Local SIM card prices in Portugal

The average Portuguese SIM card price for tourists is between €15 and €25 (around US$17–28) for around a month of service, but it depends on the package you choose. Smaller starter packs can cost less, while plans with more data or unlimited use can cost more. Prices also vary depending on whether you choose a tourist SIM card or a regular prepaid SIM that is not specifically aimed at visitors. Keep in mind that some providers may ask for ID and require a quick registration if you go with the latter option.

Network providers like MEO Portugal, Vodafone Portugal, and NOS Portugal also offer pay-as-you-go SIM cards, which let you top up data whenever needed instead of buying a fixed tourist package.

Here’s a breakdown of the three major prepaid SIM card options in Portugal:

*5G access depends on device compatibility, plan type, and local coverage. The data is up to date as of June 2026.

Where to buy a SIM card for tourists in Portugal

You can buy a Portuguese travel SIM card either in person or online. Prepaid SIM cards are commonly sold at airports, mobile operator stores, authorized resellers, tourist shops, and many supermarkets across the country. If you plan to buy a SIM card in Portugal in person, keep your passport handy — some providers may ask for ID and require a quick registration. Here are the main ways to get a SIM card for Portugal during your trip.

Buy a SIM card for Portugal at the airport

If you want to sort out your cellular data the moment you arrive, you can buy a SIM card for Portugal at Porto or Lisbon Airport. Both Humberto Delgado Airport (LIS) and Francisco Sá Carneiro Airport (OPO) have kiosks and vending machines that sell SIM cards. 

Visit a SIM card operator’s store in Portugal

Another way to buy a SIM card in Portugal is by visiting your nearest MEO, Vodafone, or NOS store. These can be found in shopping malls or in multiple districts of Lisbon and other cities. Make sure to check their store locators to find the closest store to you. 

Go to a SIM card reseller in Portugal (convenience store)

Many convenience stores sell prepaid SIM cards for Portugal. Look for signs like tabacaria (Tobacco store) or loja de conveniência (convenience store). If you’re having trouble finding one yourself, you can ask the shopkeeper if they have prepaid SIM cards behind the counter. Don’t fret if you don’t speak Portuguese — English is widely spoken in the country!

Find a Portuguese SIM card at a supermarket

Supermarkets like Continente, Pingo Doce, and Intermarché typically have sections for tourist SIM cards. Plus, you can use the opportunity to pick up some piri-piri to enjoy at home!

Get a SIM card at a tourist shop

In busy tourist areas like Lisbon, Porto, and the Algarve, you may come across travel shops and small kiosks selling SIM cards for tourists. These spots are geared toward visitors, so staff often speak English and can help you get set up quickly. Prices may be a bit higher than at official mobile stores, but if you’ve just arrived and need data fast, the convenience can be worth it.

Order a SIM card for Portugal online

Ordering a prepaid SIM card online is a great option for travelers who want their mobile data solution planned well ahead of time. However, you may run the risk of your SIM not arriving on time and having to resort to plan B. Some carriers give you the option to order a prepaid SIM card online, while carriers like Vodafone direct customers to visit a flagship store if they want a physical SIM card. If you’re already thinking of ordering a SIM card online, you should consider an even more convenient online option for finding mobile data. 

Best option for getting mobile data in Portugal: An eSIM

Our top recommendation for getting affordable mobile data in Portugal is to buy an eSIM. eSIMs, aka virtual SIM cards, are like SIM cards without the physical card. You get all the same benefits of a traditional SIM card without the hassle it takes to get one.

All you need to do is download an eSIM app, choose a data plan, install the eSIM, and activate your plan. eSIM apps like Saily make this process even easier for you because your data plan will automatically activate when you arrive in Portugal. 

With an eSIM, you can:

• Skip lines. Unless you’re buying a SIM card online, you’ll have to physically go to a store or wait in line at the airport. 

• Get instant mobile data. If you order a SIM card online, you’ll have to wait for it to arrive before inserting it and activating the data plan. Instead, you can get online in minutes by downloading an eSIM app and purchasing a plan. 

• Avoid risks. Having a physical SIM card means you can lose or damage it and that it can be stolen. A stolen SIM can especially put a damper on your trip if scammers use it to verify your phone number and get ahold of your banking info. 

Saily offers several affordable data plans for Portugal, with prices starting from US$3.99 for 1 GB (7 days). Larger plans include 3 GB for US$7.99, 5 GB for US$9.99, and 10 GB for US$16.99 for 30 days, making it a practical option whether you’re visiting for a weekend or staying longer. Travelers who need more data can also choose 20 GB for US$27.99 or an unlimited plan.

Portugal just so happens to be one of the most budget-friendly tourist destinations in Europe. Don’t burn through your budget with high international roaming fees or unnecessarily expensive data options. Try an eSIM for Portugal instead. It can also work as an eSIM for Madeira.

How to buy an eSIM for Portugal

Getting an eSIM for Portugal is usually faster than buying a physical SIM card. You can set everything up before your trip and be ready to connect as soon as you arrive:

1. Download the Saily app. Start by downloading the Saily eSIM app from the App Store or Google Play. Create an account or log in.

2. Search for Portugal. Open the app, browse destinations, and choose Portugal. If you’re visiting several countries, you can also look at regional Europe plans.

3. Pick a data plan. Choose the plan that best fits your trip length and data needs. For example, lighter users may only need 1 GB or 3 GB, while longer trips may suit 10 GB or more.

4. Install the eSIM. After buying it, tap “Install eSIM” in the app and follow the prompts on your phone. On an iPhone, you’ll be guided through your cellular settings. On an Android device, steps may vary slightly depending on the brand and model. The process usually takes only a few minutes.

5. Activate when you arrive. Once you land in Portugal, enable the Saily eSIM in your phone settings and switch mobile data to that line if needed. Many plans activate automatically when you connect in your destination.

6. Stay connected during your trip. You’re ready to use maps, rideshare apps, messages, and browsing without relying on costly roaming or hunting for public Wi-Fi.

Do you really need a SIM card for Portugal?

You don’t really need a prepaid SIM card for Portugal. Although prepaid SIM cards may be appealing because they come with a local phone number, you no longer need a local number to reach loved ones back home thanks to free apps like WhatsApp and Messenger. If you and the person you’re messaging both have an Apple device, you can also use iMessage or FaceTime to get ahold of each other. All you need to use these free apps is reliable internet, which is something you can get with a data-only eSIM. 

SIM cards are also less convenient than eSIMs and tend to be more expensive. You’ll need to spend time searching for a Portuguese SIM card in person or ordering one online and waiting for it to ship to you. On the other hand, you can just download an eSIM app and get a mobile data plan in minutes. 

Long story short — eSIMs help you save money and time. Instead of getting a prepaid data SIM card for Portugal, consider downloading an eSIM app.
