Best eSIM for Portugal 2026: What Worked in 220 Traveler Reports

Best eSIM Providers for Portugal

eSIM plans in Portugal at a glance

The matrix below sorts the ten providers we tested by their share of good Portugal reports. Our write-ups after it follow the order we would buy, weighing the number of reports, our test score and what each does best. That is why a perfect result from 2 reports does not outrank 22 good results out of 26.

Each entry keeps two numbers separate. The Vefru test score (0 to 10) comes from plans we bought with our own money and tested outside Portugal. "Worked in Portugal" counts traveler reports, labeled strong (20 or more), limited (5 to 19) or too few to judge (under 5). To see how these brands compare worldwide, read our ranking of the providers we tested.

How well each provider's eSIM works in Portugal

The Vefru score is our overall rating of the provider. The percentage shows how many reviewers said their eSIM worked well in Portugal. Since unhappy customers review more often, it is best used to compare providers with each other.

Compare all eSIM plans in Portugal

How we got these numbers: we read 220 public customer reviews that mention Portugal or a place in it, published between March 2024 and August 2026. We counted a report as "worked" when the reviewer said the eSIM connected, even with small hiccups. Strong evidence means 20 or more reports, limited means 5 to 19, and fewer than 5 is too few to judge. The Vefru test score is our own hands-on test, run outside Portugal. Prices quoted in the text were checked on 29 Aug 2026; the plan tables update separately. Some links are affiliate links; a commission never changes our scores.

GigSky eSIM in our hands

Go to GigSky website View full review

GigSky has the best mix of traveler evidence and test results for Portugal. 22 of 26 reports (strong) say it worked, and most of them date from 2026. One reviewer had data everywhere except where the local signal was poor. An Azores visitor still had data between the mountains when friends did not.

The complaints are clear. Two travelers could not get data in Portugal at all, one of them on a free plan from a Visa card deal. Another found it weaker than a rival eSIM in big Spanish and Portuguese cities. A cruise buyer spent two days getting the eSIM onto a Pixel 7, so install it at home first.

GigSky's Vefru test score is 7.2 out of 10. A live agent answered almost at once, so the help desk scored 9 out of 10. Speed scored 6, at about 114 Mbps down and 16 Mbps up after a restart. The app scored 6, but it keeps working after your data runs out. That means you can top up without Wi-Fi.

GigSky did not name its Portugal network when we checked in August 2026. It says it connects you to the fastest one available. New users get 100 MB free. Our GigSky test also found cruise plans for more than 190 routes, handy if your ship leaves Lisbon.

Global YO eSIM in our hands

Go to Global YO website View full review

Global YO has a Vefru test score of 8.0 out of 10 and scored 10 for price. It is often the cheapest brand we test. In Portugal, 14 of 16 reports (limited) say it worked, including a rural road trip and a packed music festival. Most good reports date from late 2024 and early 2025. The most recent one, from August 2026, calls the Portugal data "pretty low quality".

In our test it ran at 74 Mbps down and 72 Mbps up, then passed 150 Mbps down. The weak spot is the help desk, which scored 5 out of 10. The second reply took more than 30 minutes. You can only buy in the app, and the app stops working once your data runs out.

Some phones need the APN (the data connection name) set to "globaldata" by hand. Each eSIM also installs only once, so never delete it mid-trip. Global YO did not name a Portugal network when we checked in August 2026. Full results are in our Global YO test.

Holafly eSIM in our hands

Go to Holafly website View full review

Holafly has the cleanest record in our Portugal data: 23 of 23 reports (strong) say it worked. That includes 2 of 2 each in Lisbon, Porto and the Azores, plus 1 of 1 in Madeira. One Azores visitor switched to Holafly after Airalo failed there. A cyclist used it for maps along 250 km of the Portuguese Camino.

In our hands-on test, Holafly ran at about 30 Mbps down and up on a 5G signal. It scored 4 out of 10 for both speed and price, for a Vefru test score of 6.2. Portugal plans are unlimited only: $11.90 for 3 days, $27.50 for 7 days and $73.90 for 30 days (as of August 2026).

Holafly names MEO, NOS and Vodafone as its Portugal networks. Hotspot use is capped, but its own pages disagree on the cap (1 GB or 500 MB a day). It suits you if you stream, work online or want to stop counting gigabytes. Read our Airalo and Holafly comparison or the full Holafly test before you pay the premium.

Jetpac eSIM in our hands

Go to Jetpac website View full review

Jetpac worked in all 6 of its Portugal reports (limited), including 1 of 1 in Porto. Only Holafly has a longer run without a failed report. Portugal reviewers praise its WhatsApp help: a traveler in Porto and another who landed in the Azores both got quick fixes. One reviewer planned 10 GB for two weeks but used it up in three days.

Jetpac's Vefru test score is 6.7 out of 10. In our hands-on test it scored 9 for installation and 8 for speed, starting at about 100 Mbps down and 67 Mbps up. The app and purchase steps scored only 5. Our own help desk test waited 8 minutes for a first reply, so that also scored 5.

Its strengths suit heavy users. Unlimited plans give 3 GB per 24 hours at full speed, then up to 1 Mbps. Hotspot use has no cap. Packs of 3 GB or more keep WhatsApp, Uber and Google Maps free after your data runs out. Jetpac also gives you airport lounge access if your flight is delayed.

Its Portugal page did not name a network when we checked in August 2026; NOS and Vodafone are reported but not verified. The same page listed 20 GB at $35.00 but 30 GB at $23.99 (as of August 2026), so check the price before you pay. Full results are in our Jetpac test.

Nomad eSIM in our hands

Go to Nomad website View full review

Nomad has more Portugal reports than any other brand we tested: 28 of 36 (strong) say it worked. It did well on the islands, with 2 of 2 in Madeira and 2 of 2 in the Azores. The cities look weaker: 1 of 3 in Lisbon and 0 of 1 in Porto.

The bad reports are specific. One eSIM stopped after two days, and a Porto visitor lost service for the last two days of their trip. A Lisbon arrival had no data at the airport for a long time. A traveler in rural Portugal had to restart the phone every morning to reconnect.

Nomad's Vefru test score is 6.8 out of 10. We measured 144 Mbps down, and the app is well built. The help desk scored 2, with no direct route to a person. Unlimited plans slow to 512 kbps after 2 GB a day, per our Nomad test.

Nomad lists "MEO / Vodafone / Sonaecom" for Portugal. Sonaecom is an old company name, so we could not confirm the exact networks. Its page also warns that coverage may exclude overseas territories, so check Madeira and the Azores before you buy. Activate within 60 days, or the plan starts on its own.

Yesim worked in 6 of 6 Portugal reports (limited). It also went 3 of 3 in Lisbon, the best Lisbon record among the brands we tested. Its Vefru test score is 6.2 out of 10, pulled down by a help desk that scored 2. It did not name a Portugal network when we checked in August 2026.

Unlimited costs €24.00 for 7 days on Yesim's euro price list (as of August 2026). Its fair use limit is not stated as a number. Our Saily test found that Yesim starts the plan right after purchase, so buy it close to your trip. More in our Yesim test.

eSIM4Travel, Saily and GoMoWorld in Portugal: Top Test Scores, Too Few Reports

These three brands have our highest Vefru test scores: 8.8, 8.5 and 8.2 out of 10. Each has fewer than 5 Portugal reports, which is too few to judge how they work here. That is why they sit below brands with more traveler evidence.

eSIM4Travel eSIM in our hands

Go to eSIM4Travel website View full review

eSIM4Travel has our highest Vefru test score, 8.8 out of 10, including 10 for price and 10 for its help desk. It is also the cheapest verified 10 GB option for Portugal at $7.96 for 30 days. Smaller plans cost $3.02 for 3 GB and $4.44 for 5 GB, both for 30 days (as of August 2026).

The Portugal evidence is thin: 1 report, which worked, is too few to judge. Its plan title lists MEO, Vodafone and NOS, but the network widget on the same page shows only Vodafone and MEO. Unlimited plans start at $7.26 for 3 days (as of August 2026), with 3 GB a day at full speed. After that the page gives two different slowdown speeds: 1 Mbps and 128 kbps.

There is no app, so you buy and top up on the website. You need Wi-Fi to buy more once data runs out. In our test it reached 116 Mbps down and 89.5 Mbps up. Activate within 90 days of purchase. Details are in our eSIM4Travel test.

Saily eSIM in our hands

Go to Saily website View full review

Saily has a Vefru test score of 8.5 out of 10, with 10 for its help desk and 9 for its app. Its Portugal page names all three big networks: MEO, Vodafone and NOS. In Portugal, 3 of 4 reports say it worked, which is too few to judge. The one failure says the data lasted about 10 minutes.

Prices sit in the middle (as of August 2026): 1 GB for 7 days costs $3.99. Over 30 days, 5 GB costs $9.99 and 10 GB costs $16.99. You get 180 days to activate before the plan starts on its own. The app has a built-in ad blocker that saves data, and our test measured 174 Mbps down and 70 Mbps up.

Check two things before you buy. The Portugal page mentions calls and SMS "for Portugal", but the number add-on is a US number. We also could not confirm the speed cap on its unlimited plans. See how its help desk ranks in our help desk test, or read the full Saily test.

GoMoWorld had the fastest result in our test, up to 1,350 Mbps down, with no slowdown after 10 GB in one day. Its Vefru test score is 8.2 out of 10. Only 2 reports cover Portugal (both worked, in Lisbon and Madeira), too few to judge. The Lisbon traveler switched to it after Nomad left them without service in the old town.

GoMoWorld did not name a Portugal network when we checked in August 2026. Users report a choice of NOS or MEO, which we could not confirm. Plans start at €3.99 (as of August 2026), stay valid until you start them, and are refunded in full if activation fails. Human help is available weekdays only, 8:00 to 17:00, per our GoMoWorld test.

Airalo eSIM in our hands

Go to Airalo website View full review

Airalo is the best-known name here, but it has the weakest Portugal record of the brands we tested. 13 of 19 reports (limited) say it worked. Lisbon went 2 of 5, Porto 0 of 1 and the Azores 1 of 3.

Three friends spent a full day in Lisbon with no data on any phone. A Porto visitor's eSIM cut out until they bought another. One traveler found the Portugal plan never connected in the Azores. Another lost data after moving between islands, and the help desk fixed it within a couple of hours.

Airalo's Vefru test score is 7.3 out of 10, with 9 for purchase and installation but 4 for price. Its product page names NOS, Vodafone and MEO. 7 days of unlimited data cost $27.00 (as of August 2026). If Portugal is one stop of many, its EU + UK plan starts at $4.00 (as of August 2026). Before you buy, look at our Airalo alternatives or the full Airalo test.

Maya Mobile, Ubigi, Roamless and Simify in Portugal: Reported but Not Tested

Four more brands appear in the Portugal reports, but we have not tested them yet. Without our own score, we list their numbers and do not rank or recommend them.

• Maya Mobile: 49 of 51 reports (strong) say it worked, the largest sample in our data. That includes 3 of 3 in Madeira and 2 of 2 in the Azores. It charges $3.33 a day in every country (as of August 2026) and renews while its Travel Mode is on. It claims no caps, but a third-party report says it slows after 30 GB, which we could not confirm.
• Ubigi: 13 of 16 reports (limited), with 3 of 4 in Lisbon and 0 of 1 in the Azores. It runs on MEO only, so there is no backup network. 7 days of unlimited data cost $19.00, with 20 GB at full speed and 2 Mbps after that (as of August 2026).
• Roamless: 6 of 9 reports (limited), with 1 of 1 in the Algarve but 0 of 1 in southern Portugal. Its credits never expire, and it has no unlimited plan.
• Simify: 5 of 5 reports (limited). It did not name a network when we checked in August 2026, and you get 6 months to activate.

Best eSIM Plans for Portugal

The tables below show current prices from our comparison tool for the most common data sizes. If you are unsure what size to pick, our data needs article breaks it down by activity. Light users can check what 5 GB covers before paying for more.

Driving on into Spain? Our Spain eSIM comparison covers the Spanish side, or search both countries at once with our Portugal and Spain plan search. For other trips, see the cheapest eSIMs we found.

Price per GB by Provider in Portugal

Plan prices alone are hard to compare, because each provider sells different data sizes and plan lengths. So we worked out the price per GB ourselves. For each provider, the chart takes its Portugal plans from 1 to 10 GB that last 6 to 14 days, a typical one- or two-week trip. It then shows the median price per GB. The median is the middle value, so one unusually cheap or expensive plan does not skew the result.

Provider pages do not show this figure side by side. We calculate it from the same price data as our comparison tool. A shorter bar means cheaper data.

Use the chart to build a shortlist, then check the tables below for the exact size you need. A low price per GB does not prove an eSIM works well in Portugal, so weigh it against the traveler reports in our provider reviews.

Best eSIM for Lisbon, Porto, Madeira and the Azores

Below are the places travelers named in our Portugal reports. Our overall pick, GigSky, has only 4 place-level reports (Lisbon and the Azores). Where no tested brand has 3 or more reports, the country pick applies.

Best eSIM for Lisbon

Lisbon has the most reports, with 15 of 21 good ones, and the widest spread between brands. Yesim went 3 of 3, while Airalo managed only 2 of 5 and Nomad 1 of 3. One Airalo group of three spent a full day in the city with no data on any phone.

Coverage itself is good here: ANACOM's drive tests rank the Lisbon metro area as the best-covered mainland region. Our Lisbon pick is Yesim, the only tested brand with 3 or more reports here. GigSky and Holafly also went 2 of 2. If you land with no data, travelers report Vodafone shops at Lisbon airport (see local SIM options).

Best eSIM for the Azores

The Azores gave 9 of 12 good reports, and the islands are where the networks differ most. In ANACOM's 2023 Azores tests, MEO averaged 50.8 Mbps down in Horta, against 28.7 for NOS and 22.4 for Vodafone. At Lajes das Flores, MEO also had the fewest no-signal samples: 8.3%, against 12.2% for NOS and 12.5% for Vodafone.

GigSky, Holafly and Nomad each went 2 of 2 here, too few to judge alone, so our country pick GigSky applies. Airalo worked in only 1 of 3, and one traveler said its Portugal plan never connected on the islands. Holafly names MEO among its networks. Nomad's page warns that coverage may exclude overseas territories, even though both Nomad reports here were good.

Best eSIM for Madeira

All 7 Madeira reports say the eSIM worked. Maya Mobile went 3 of 3, Nomad 2 of 2, and GoMoWorld and Holafly 1 of 1 each. No brand we tested has 3 reports here, so our country pick, GigSky, applies.

A 2024 Umlaut audit found MEO covering close to 100% of Funchal's population on 4G and 85% on 5G, according to secondary reporting. That audit covers Funchal only, so we cannot say how the networks compare on hiking trails. Holafly, Saily and Airalo all list MEO among their Portugal networks.

Mobile Networks in Portugal: MEO, NOS, Vodafone and DIGI

Portugal has four mobile networks. MEO, NOS and Vodafone carry nearly all traffic. DIGI has been live since 4 Nov 2024. The table uses the nPerf 2025 barometer (45,449 tests) and ANACOM's Q3 2025 figures.

MEO and NOS share first place, with 103,717 and 106,261 nPerf points, inside nPerf's stated 1.5% margin. MEO is the fastest, above all on 5G, and it led ANACOM's Azores tests. NOS has the best latency and streaming results. It also has 5G on 94.0% of its sites, so you are more likely to land on a 5G signal.

Vodafone is a fair third, and DIGI is not worth chasing on a short visit. One third-party ranking based on Ookla data names Vodafone fastest (Jul 2025 to Jun 2026), which we could not confirm. ANACOM's July 2026 draft decision would require 100 Mbps for at least 90% of residents in 813 more parishes by 31 Dec 2028. It was not final when we checked.

Airalo, Holafly and Saily officially name all three big networks, and eSIM4Travel does too, with a conflicting widget. Ubigi uses MEO only and ByteSIM uses NOS only, so neither has a fallback in weak spots. Our multi-network eSIM article explains why a fallback helps, and our 4G and 5G comparison shows when 5G is worth it. To check a specific address, use the official GEO.ANACOM coverage map or MEO's coverage checker.

Local SIM and eSIM Options in Portugal

A local plan beats a travel eSIM in two cases: you need a Portuguese +351 number, or you want unlimited data for several weeks. For a short, data-only trip, a travel eSIM is usually cheaper and skips the shop queue. One Maya Mobile customer could not rent a bike in Porto because the shop needed to text them.

The Vodafone tourist eSIM starts counting days when you install it, not when you connect, so install it after landing. Local prices and deals move often, so check the operator's page on the day you buy. All Vodafone tourist plans are data-only. For a +351 number with calls and texts, a prepaid voice SIM from MEO, NOS or DIGI is the route.

Travelers report a Vodafone store by baggage belt 9 at Lisbon airport, open 07:00 to 22:00, and a small Vodafone store in Porto arrivals. A Porto buyer said staff asked for no ID. We could not confirm the ID rules for prepaid SIMs. ANACOM only states that you need ID to move a number between networks.

Want calls without a local SIM? Jetpac sells in-app voice packs, and our Global YO test found a paid calling add-on. Our eSIM and SIM comparison lays out the trade-offs.

How to Set Up an eSIM for Portugal

Set everything up at home on Wi-Fi, then switch the eSIM on when you land. These steps cover the traps that show up in our Portugal reports.

1. Check that your phone takes an eSIM. iPhones sold in mainland China, Hong Kong or Macao have none, apart from the 13 mini, 12 mini, SE 2020 and XS. Our list of eSIM phones covers the rest.
2. Buy early, but watch the activation window. It is 60 days for Nomad, 90 days for Airalo and eSIM4Travel, 180 days for Saily and 6 months for Ubigi. GoMoWorld plans stay valid until you start them.
3. Install the eSIM before you fly with our iPhone setup steps or Samsung setup steps. Keep it installed for the whole trip, because a Global YO eSIM cannot be reinstalled.
4. When you land, turn the eSIM on, set it as your data line and switch on data roaming. Travel eSIMs need roaming on, even in the country they are sold for.
5. No data? Restart the phone first; a Nomad user in rural Portugal did this every morning. On Global YO, set the APN to "globaldata". Our eSIM fixes cover the other common faults.

Free eSIM trials and data-saving tips for Portugal

GigSky gives new users 100 MB free, and GoMoWorld has a free trial in selected destinations. Our Nomad test also found a free 1 GB trial for new users. Some Visa cards include free GigSky data, which is how several Portugal reviewers got theirs. More options are in our free eSIM roundup.

To stretch a small plan, download offline maps before you leave the hotel Wi-Fi. Saily's ad blocker also cuts data use if you buy Saily. Our data-saving tips list more ways to make a plan last.

Summary: Best eSIM for Portugal in 2026

Across 220 traveler reports, 191 said the eSIM worked in Portugal. GigSky gives the best balance, with 22 of 26 good reports and a Vefru test score of 7.2. Global YO is the value pick, and Holafly is the unlimited pick with 23 of 23 good reports.

Jetpac went 6 of 6 and has no hotspot cap on unlimited plans. eSIM4Travel, Saily and GoMoWorld score best in our hands-on tests, but their Portugal reports are still too few to judge.

Be careful with Airalo in Lisbon, where only 2 of 5 reports worked. Buy a local SIM only if you need a +351 number or weeks of unlimited data. Heading on to Spain, Morocco or the UK? Our Spain, Morocco and UK eSIM comparisons cover those legs.

For most trips, the best eSIM for Portugal is GigSky, backed by Global YO if price matters most. Compare Portugal eSIM plans before you pay, since prices change often.
