Portugal eSIM in 2026: plans, tourist SIMs and Spain

Staying connected in Portugal is easy, and all three big operators now sell something aimed at visitors. This guide compares an eSIM bought before you fly with a Portuguese prepaid SIM, explains what we found on ID, and covers the airports, the islands and the border with Spain. Every price is dated and sourced.

Going on to Spain? Our Spain eSIM guide covers plans and prices there.

Do you need an eSIM in Portugal?

If your SIM is from an EU or EEA country, probably not. Portugal is in the EU, so "Roam like at home" applies: calls, texts and data cost what they cost at home. The European Commission's Your Europe service says the regime also covers Iceland, Liechtenstein and Norway "as well as in Moldova and Ukraine" (Your Europe, checked 4 November 2026).

Two catches: your operator may set a fair-use limit on roaming data, and may charge extra if, over 4 months, you spend more time and roam more abroad than at home (Your Europe). Our Italy eSIM guide explains EU roaming in more detail.

If your SIM is from outside the zone (UK, US, Canada, Australia and others), plan ahead. "Other countries are not covered by this regime", Your Europe says, though many operators extend similar offers. A data eSIM or a local plan is the practical choice.

Networks and coverage

Portugal's main mobile operators:

• MEO (MEO – Serviços de Comunicações e Multimédia, S.A., as its own site names it).
• NOS.
• Vodafone Portugal.
• DIGI, the newcomer. DIGI says it publicly launched its offer "No dia 4 de novembro" (on 4 November) 2024 (DIGI blog, in Portuguese, dated 4 December 2024), and added prepaid plans in August 2025.

What Airalo's label means. Airalo's Portugal plan lists two networks, NOS and MEO, both marked 5G. The same page's description says "4G Data-only eSIM" and "Operates on the NOS, Vodafone, and MEO networks" (Airalo plan page, as of 4 November 2026). We could not resolve the difference; expect NOS or MEO, and possibly Vodafone.

Islands. Airalo's plan notes say: "Coverage also includes Madeira and the Azores." None of the operator offer pages we read states island coverage either way, so we do not claim it for them. We do not rank the networks; check your route and download offline maps.

eSIM vs a local prepaid SIM

ID: we could not confirm a rule either way. Unlike Spain, where the law requires an identity document for every prepaid SIM, we found no Portuguese law, and no page from the regulator ANACOM, that requires ID to buy one. A citizens' petition to Portugal's parliament asks to make identification compulsory for prepaid cards, "seja ele nacional ou estrangeiro" (national or foreign), because anonymous cards are possible today (Assembleia da República petition PDF, in Portuguese); the PDF is undated and we do not know its outcome. NOS says its prepaid cards need no "documentação complexa" (complex paperwork) (NOS, in Portuguese), and its Travel eSIM sign-up form asks for a name and email. But the online order form on NOS's mobile data page asks for a passport number and a Portuguese delivery address, such as your hotel (NOS). Expect to be asked; carry your passport.

Check roaming before you buy. NOS Travel and Vodafone's Portugal & Europe eSIMs include EU data. Vodafone's Portugal-only eSIM, MEO's Enjoy card and NOS's prepaid data card work in Portugal only.

Local prices as of 4 November 2026, in euro (EUR). USD figures are our approximate conversion at the European Central Bank rate that day (EUR 1 = USD 1.1267).

Vodafone's FAQ gives smaller EEA allowances (25 GB and 45 GB) than its price cards, and its promotion text says it ran "until 31/08/2026", yet the promotional prices were still shown; we used the cards. MEO's Enjoy page and shop disagree on price; we list the tariff page. DIGI also sells 50 GB for EUR 4 and 150 GB for EUR 5 a month. We did not check EU roaming on MEO M Móvel or DIGI. Prices change often.

Price per GB. On paper DIGI is cheapest: a EUR 10 SIM whose balance covers the EUR 7, 200 GB plan, about USD 0.06 per GB, if you can reach a reseller. MEO's EUR 10 card with 70 GB in its first 30 days is about USD 0.16 per GB. Airalo's fixed plans below run from USD 0.70 to USD 4.00.

Which wins? For one week, it is close. Airalo's 10 GB for 7 days costs USD 10.00; NOS Travel gives 15 GB, minutes and EU data for about USD 11.26; Vodafone's 10 GB Portugal eSIM is about USD 11.27. No operator sells a 7-day unlimited plan, but NOS's 15-day unlimited data card (about USD 11.27, Portugal only) undercuts Airalo's 7-day unlimited (USD 27.00). For 15 days, Vodafone Portugal & Europe or NOS Travel Unlimited (about USD 22.50) costs under half Airalo's 15-day unlimited (USD 48.00). For about a month, Vodafone's 30-day Portugal & Europe eSIM (about USD 33.80) beats Airalo's 30-day unlimited (USD 69.00), though Airalo's 10 GB for 30 days (USD 11.00) is cheapest if you need little data. Airalo's plan data shows no ID check, and it works the moment you land.

Where to buy. Vodafone and NOS sell their tourist eSIMs online. Vodafone says that if you prefer a physical SIM "you can get it at a Vodafone store". NOS lists its own stores, airports and online. At Lisbon and Porto, ANA's airport shop listings show Vodafone shops and no MEO or NOS store; details are in the city section below. DIGI sells prepaid SIMs only through its official resellers (DIGI, in Portuguese).

Airalo plans for Portugal

Airalo's Portugal eSIM is data-only and covers Portugal only, including Madeira and the Azores. Prices below are as shown on Airalo's Portugal plans (opens Airalo in a new tab) on 4 November 2026. The page showed USD; your currency may differ.

Airalo also lists "Unlimited" plans: 3 days USD 11.50, 5 days USD 19.00, 7 days USD 27.00, 10 days USD 34.50, 15 days USD 48.00 and 30 days USD 69.00. Speed drops to 1 Mbps after 3 GB of use per day.

What the numbers say:

• 10 GB for 30 days costs USD 11.00, only USD 1.00 more than 10 GB for 7 days: the safer buy if your dates might change.
• Is a regional plan cheaper? Not for Portugal plus Spain. Airalo's Europe plan (41 countries, including both) costs USD 28.00 for 10 GB over 15 days. Separate Portugal and Spain plans at 10 GB for 15 days cost USD 24.00 together (USD 10.50 plus USD 13.50). The Europe plan pays off only if you add more countries.
• Alternative: Yesim. Yesim's Portugal eSIM (opens Yesim in a new tab) sells data-only fixed plans, all valid for 30 days. As of 4 November 2026 it showed 10 GB for USD 19.20 and 20 GB for USD 26.40 (shown as discounts from USD 30.00 and USD 60.00). Airalo is cheaper at both sizes: USD 11.00 for 10 GB and USD 19.00 for 20 GB over 30 days in the table above.
• Hotspot: the plan details do not mention tethering; check with Airalo if you need it. NOS says its Travel plans can be used as a hotspot.
• Top-ups: Airalo says the plan is "Rechargeable online with no expiry", and its plan data shows no ID check.

Setting it up

Before you fly

1. Check that your phone supports eSIM and is not locked to your home carrier.
2. Buy and install the eSIM at home over Wi-Fi. For Airalo's Portugal plan, validity starts when the eSIM connects to a network in Portugal, not when you install it (Airalo's Portugal plans (opens Airalo in a new tab)).
3. Save the QR code or installation details offline in case you need to reinstall.

At Lisbon or Porto

1. Switch mobile data to the Portugal eSIM line.
2. Turn on data roaming for the eSIM line. Airalo lists this as required on iOS and Android, and Vodafone gives the same instruction for its eSIMs.
3. If something does not work, use the airport's free Wi-Fi (see the city section below).

What to turn off

• Data roaming on your home SIM, unless you are on an EU/EEA plan that includes it.
• Automatic data switching between lines (iPhone: "Allow Cellular Data Switching"; Android phones have similar settings). It can quietly use your home SIM.

If you'd rather not deal with transport on arrival, Welcome Pickups (opens Welcome Pickups in a new tab) lists fixed-price transfers from Lisbon airport from EUR 28, as of 4 November 2026, against a metered taxi it puts at about EUR 15 to the centre by day.

Arriving in Lisbon or Porto

Lisbon

For an eSIM in Lisbon, install it before you fly. ANA's shop listings, which cover all its airports, show only Vodafone among telecom shops: no MEO or NOS store. One Vodafone listing gives two outlets, "Terminal 1 - Arrivals" before security (7:00 to 23:00) and "Terminal 1 - Baggage" after security (6:00 to 21:00), selling "voice and data cards" (ANA, Technology shops, as of 4 November 2026). The listing does not name the airport. Its "Terminal 1" naming matches Lisbon Humberto Delgado, where Welcome Pickups' page says arrivals are in Terminal 1 and Terminal 2 is for departures only, but we could not confirm it. On 4 November 2026 Lisbon airport's own website returned a bot check, so we could not read its Vodafone or Wi-Fi pages, and we cannot tell you the Wi-Fi network name or time limit. If the baggage-hall shop is Lisbon's, it is the one you pass after landing. For a long weekend, Airalo's 10 GB for 7 days (USD 10.00) or NOS Travel's 15 GB (about USD 11.26) is enough.

Porto

For an eSIM in Porto, sort it out at home too. ANA lists one Vodafone shop at Francisco Sá Carneiro, "Antes da Segurança, Piso 0" (before security, floor 0), open 7:30 to 21:00, selling "cartões de voz e dados" (voice and data cards) (ANA Porto, in Portuguese, as of 4 November 2026). Before security should mean the public side of the terminal, reachable after you land (our reading; ANA does not say). Free Wi-Fi is on the "_VINCI Airports WiFi" network: accept the terms in your browser and connect; the airport calls it "free and unlimited" (ANA Porto). Faro's airport pages were also behind a bot check, so we cannot confirm a shop or Wi-Fi there.

Onward to Spain

Spain is in the EU, so your roaming rights carry over. An EU or EEA SIM roams there at home prices, and a Portuguese plan with EU roaming does too.

Which Portuguese plans work there? NOS Travel (15 GB on the 7-day plan, 30 GB or 52 GB on the unlimited plans) and Vodafone's Portugal & Europe eSIM (30 GB or 55 GB in the EEA and UK) both cover Spain. Vodafone's Portugal-only eSIM, MEO's Enjoy card and NOS's prepaid data card do not. Airalo's Portugal plan covers Portugal only; add its Spain plan, or see our Spain eSIM guide for Spanish options.

Near the border, your phone may join a Spanish network. On an EU-roaming plan that is fine; on a Portugal-only plan, manual network selection on a Portuguese network can avoid losing data (our suggestion; we found no regulator advice).

Quick answers

Can I make calls or send SMS? Not with Airalo or Vodafone's eSIMs. NOS Travel includes 3,500 minutes and SMS, MEO M Móvel 1,000 and DIGI unlimited national calls.

Will I keep WhatsApp? Yes. WhatsApp stays linked to your registered number, not to the line carrying your data. Keep your home SIM in for verification codes.

How do I top up? Airalo tops up in its app. NOS Travel cannot be topped up; you buy a new one. We did not find Vodafone's rule for its tourist eSIMs. MEO's Enjoy card is extended by topping up, and DIGI plans renew each month if you have credit.

Which currency? Portugal has used the euro since 1 January 1999 (European Commission), so all local prices above are in euro.
