Best eSIM for Portugal in 2026: Cheap and Unlimited Plans

My top pick for most travelers, and the best eSIM for Portugal in 2026, is Airalo. Its 10 GB plan for 30 days costs $11.00 and runs on NOS, Vodafone and MEO with 5G. I use Airalo in Portugal. The networks are strong in the cities and along the coast, and a Portugal plan covers the Azores and Madeira as well.

My picks

• Best for most trips: Airalo eSIM for Portugal, 10 GB for 30 days at $11.00, NOS, Vodafone and MEO with 5G, 365 days to start the plan.
• Cheapest pay as you go: Roamless eSIM for Portugal, credits at $1.95 for 1 GB, MEO and NOS with 5G, no speed limit and no expiry on the credits.
• Best unlimited data: Saily eSIM for Portugal, unlimited 7 days at $26.99, MEO, Vodafone and NOS, 5 GB a day at full speed.
• Best if your trip goes beyond Portugal: Ubigi eSIM for Portugal, Europe plan with 10 GB for 30 days at $15.00, MEO in Portugal and Orange in Spain, 38 destinations.
• Best when your data runs out: Jetpac eSIM for Portugal, 10 GB for 30 days at $18.00, Vodafone and NOS, free WhatsApp chat, Uber and Google Maps after the pack is empty.

These five are the providers I trust for Portugal. To compare their plans side by side, see all five on one page.

• My verdict: the best eSIM for Portugal in 2026

I'm a digital nomad with 50+ countries behind me since 2017, and I work online. Data the moment I land is part of my workday: calls, email, and a laptop running on my phone's hotspot. For the last five years every trip has started with an eSIM bought before the flight.

I lived in Porto for a long time, and I know Lisbon, the Azores and Madeira from several trips.

To find the best eSIM for Portugal for your trip, start with the tables below. They compare five eSIM cards for Portugal on 10 GB, 20 GB and unlimited plans.

Best unlimited eSIM for Portugal

An unlimited data eSIM for Portugal is worth it when a laptop runs on your hotspot or you stream every evening. For maps, photos and messages a 10 GB plan is the better buy. Most "unlimited" plans give a daily allowance at full speed, then a slow speed; Ubigi counts per plan. Holafly lists no daily cap.

Roamless sells no unlimited plan for Portugal; its fixed plans have no speed limit instead. Holafly is unlimited only, on MEO, NOS and Vodafone, with hotspot sharing limited to 1 GB a day.

Airalo eSIM for Portugal: best for most trips

Pros

• NOS, Vodafone and MEO, all with 5G
• 10 GB for 30 days at $11.00
• 365 days from purchase to start
• Madeira and the Azores named on the plan

Cons

• Data only, no phone number
• IP address may show as outside Portugal

Airalo is the eSIM card for Portugal I recommend for most trips, from a long weekend in Lisbon to a month of remote work. Skip it only if you need a phone number or a bigger daily allowance on unlimited, where Saily wins.

The plan I recommend is 10 GB for 30 days at $11.00, so 1 GB costs $1.10. Take 20 GB and that drops to $0.95. Only Roamless matches that.

The reason I use Airalo for Portugal is simple: it's fast, the signal is very good, and my laptop runs on the hotspot for calls and email. Airalo runs on NOS, Vodafone and MEO, all with 5G, and the eSIM switches between them.

Validity starts when the eSIM first connects to a network in Portugal, not when you install it, and you have 365 days from purchase to start. A plan bought today still works for a trip next spring. You lose no days before landing.

One warning before you buy. Airalo also sells a separate Azores eSIM, and 10 GB there costs $29.00. Your Portugal plan already covers Madeira and the Azores, so the island version costs you more for the same data. Buy the Portugal plan instead.

When you fly on from Lisbon to Ponta Delgada, the same plan keeps working, with no second eSIM and no new install.

Airalo's IP address may appear from outside Portugal, so a website can place you in another country; your data use isn't affected.

Here are Airalo's plans for Portugal:

• 1 GB for 3 days: $4.00
• 3 GB for 3 days: $6.00
• 3 GB for 7 days: $6.50
• 5 GB for 7 days: $7.50
• 10 GB for 7 days: $10.00
• 5 GB for 15 days: $8.00
• 10 GB for 15 days: $10.50
• 20 GB for 15 days: $18.50
• 5 GB for 30 days: $9.00
• 10 GB for 30 days: $11.00
• 20 GB for 30 days: $19.00
• 50 GB for 30 days: $35.00
• Unlimited (3 GB a day at full speed, then 1 Mbps): 3 days $11.50, 5 days $19.00, 7 days $27.00, 10 days $34.50, 15 days $48.00, 30 days $69.00

Roamless eSIM for Portugal: cheapest pay as you go

Pros

• Credits at $1.95 for 1 GB, never expire
• 10 GB for 30 days at $10.95, five cents under Airalo
• No speed limit on any plan
• 500 MB free for new users

Cons

• No unlimited plan
• Phone number only as a paid subscription

At $1.95 for 1 GB, Roamless credits are my pay-as-you-go pick for a trip of unknown data needs, or one that crosses three countries. I don't recommend it if you want unlimited data, because Roamless sells none for Portugal.

Credits work like a prepaid balance you buy once, and they never expire. The same balance works in 200+ destinations on one eSIM. A three-day Lisbon stopover that uses 2 GB costs you $3.90, and the rest waits for the next trip. New users start with 500 MB free.

For a planned stay there are fixed plans too, and 10 GB for 30 days at $10.95 costs five cents less than at Airalo or Ubigi. Only Jetpac's sale price beats it. A plan runs 30 days from the first byte used in Portugal, not from install, and you have 12 months to start it.

Roamless gives you two networks, MEO and NOS, both with 5G, and in cities and along the coast that's plenty. NOS alone reports 5G for 99.6 percent of the population outdoors, though a spot where only Vodafone has signal leaves you offline.

There's no daily allowance and no speed limit, so the 50 GB plan at $34.95 is a full 50 GB for a month of laptop work. Hotspot is included on every plan. On the train from Lisbon to Porto you run the laptop on the hotspot without watching a daily counter.

Here are Roamless's plans for Portugal:

• 500 MB for 30 days: free for new users
• 1 GB for 30 days: $3.95
• 3 GB for 30 days: $6.45
• 5 GB for 30 days: $8.95
• 10 GB for 30 days: $10.95
• 20 GB for 30 days: $18.95
• 50 GB for 30 days: $34.95
• Pay-as-you-go credits: 1 GB costs $1.95, no expiry
• Unlimited: not offered

Saily eSIM for Portugal: best for unlimited data

Pros

• Unlimited with 5 GB a day at full speed
• MEO, Vodafone and NOS with 5G
• Activates by itself when you land in Portugal
• Own Azores and Madeira pages, same plan

Cons

• 10 GB costs $16.99, $5.99 more than Airalo
• Plan starts by itself 180 days after purchase

Seven days of unlimited cost $26.99 at Saily, and the daily allowance is 5 GB at full speed, the biggest of the five I review. Over a week that's 35 GB at full speed, so 1 GB costs about $0.77 if you use it all. Airalo gives 3 GB a day. That's the plan for laptop workers and for families sharing one hotspot.

After 5 GB in a day the speed drops to 1 Mbps at most until the next day, when the allowance resets. Over 30 days that's up to 150 GB at full speed. Light users never reach that.

Saily runs on MEO, Vodafone and NOS with 5G and covers all nine Azores islands and Madeira, with its own page for each island group. Hotspot sharing has no cap. On a beach day in the Algarve the laptop runs on the hotspot, and if the allowance is gone by evening, it's back the next morning.

Saily's plans activate by themselves when you arrive in Portugal. If you haven't arrived within 180 days of purchase, the plan starts on its own, used or not. Buy it within six months.

Light users pay for data they won't touch, since a 10 GB plan costs much less at Airalo or Roamless. Saily is for heavy use. The app also sells an optional US phone number; more on that in the Saily eSIM review.

Here are Saily's plans for Portugal:

• 1 GB for 7 days: $3.99
• 3 GB for 30 days: $7.99
• 5 GB for 30 days: $9.99
• 10 GB for 30 days: $16.99
• 20 GB for 30 days: $27.99
• Unlimited (5 GB a day at full speed, then up to 1 Mbps): 5 days $18.99, 7 days $26.99, 10 days $34.99, 15 days $48.99, 20 days $59.99, 25 days $65.99, 30 days $71.99

Ubigi eSIM for Portugal: best Europe plan for multi-country trips

Pros

• Europe plan with 10 GB for 30 days at $15.00
• Portugal plan with 10 GB for 30 days at $11.00
• Unlimited 7 days at $19.00, cheapest here
• Starts on arrival in Portugal, no step needed

Cons

• Expires if not started within six months
• No one-off 20 GB plan, 25 GB costs $28.00

As you drive from the Algarve into Spain, a Portugal-only plan stops at the border; Ubigi's Europe plan moves you to Orange and your maps keep loading. That is why I recommend Ubigi when Portugal is one leg of a longer European trip.

At $15.00 for 10 GB over 30 days, the Europe plan covers 38 destinations, Portugal on MEO and Spain on Orange. That's $4.00 more than Ubigi's Portugal-only 10 GB. No other Europe plan here costs less.

MEO is the largest operator in Portugal, with 36 percent of mobile subscribers, and reports 5G for 97 percent of the population. Wherever MEO has signal, which on the coast and in the cities is nearly everywhere, Ubigi works, with no second network to switch to. Ubigi has 5G on MEO in Portugal, though Google Pixel phones may not get it.

Ubigi's unlimited 7 days at $19.00 works per plan rather than per day. That's the cheapest unlimited week here. You get 20 GB at full speed for the whole week, then 2 Mbps, enough for messaging, email, maps and light browsing. The 30-day version gives 60 GB.

Validity starts on arrival in Portugal, or right away if you buy while already there, and you have six months to start it before it expires. Monthly subscriptions renew every month and can be canceled only after three months, so for one trip take a one-off plan.

Here are Ubigi's plans for Portugal:

• 3 GB for 30 days: $6.00
• 10 GB for 7 days: $9.00
• 10 GB for 30 days: $11.00
• 25 GB for 30 days: $28.00
• 50 GB for 30 days: $35.00
• Unlimited (then 2 Mbps): 7 days $19.00 with 20 GB at full speed, 15 days $34.00 with 30 GB, 30 days $48.00 with 60 GB
• Europe, 38 destinations: 3 GB for 30 days $7.00, 10 GB for 30 days $15.00, unlimited 7 days $23.00 and 30 days $62.00

Jetpac eSIM for Portugal: online even when data runs out

Pros

• WhatsApp, Uber and Google Maps work after data runs out
• Vodafone and NOS with 4G/5G
• 3 GB for 7 days at $6.00
• Free airport lounge when your flight is delayed

Cons

• Three months from purchase to start
• Longest unlimited plan is 21 days

On any pack of 3 GB and above, WhatsApp chat, Uber and Google Maps keep working after your data is gone. That's the main reason to pick Jetpac, and it suits the traveler who once ran out of data on a trip and remembers it. Other apps need a top-up.

Jetpac runs on Vodafone and NOS, shown as Optimus, NOS's old name, with 4G and 5G. In Lisbon, Porto and along the coast two networks are enough, though a village served by MEO alone leaves you without data. Unlimited packs give 3 GB every 24 hours at full speed, then up to 1 Mbps until the next cycle, and the longest runs 21 days. There's no 30-day unlimited pack.

Jetpac gives you the least time to start. An unused pack stays in your account for 3 months from purchase, so buy it within three months of the trip. It starts when the eSIM connects to a Portuguese network, and the packs carry no SMS and no number, so calls go through voice packs in the app.

On a day trip to Sintra the pack runs out at the palace gate, and the map and your WhatsApp chats still work.

I don't recommend Jetpac at its full price, because 10 GB for 30 days costs $18.00 there, the most expensive 10 GB here. Right now that pack is on sale at $10.50 with no end date shown, so check the price on the day you buy.

Here are Jetpac's plans for Portugal:

• 1 GB for 4 days: $7.00
• 3 GB for 7 days: $6.00
• 5 GB for 30 days: $7.50
• 10 GB for 30 days: $18.00
• 15 GB for 30 days: $27.00
• 20 GB for 30 days: $35.00
• 30 GB for 30 days: $50.00
• 40 GB for 30 days: $60.00
• Unlimited (3 GB every 24 hours at full speed, then up to 1 Mbps): 3 days $15.00, 5 days $25.00, 7 days $37.00, 10 days $55.00, 15 days $78.00, 21 days $105.00

Does an eSIM work in Portugal? Networks and coverage

Yes. MEO, NOS and Vodafone carry every travel eSIM in this article, and each reports 4G for close to 100 percent of the population. For 5G, MEO reports 97 percent of the population, NOS 99.6 percent outdoors, and Vodafone 99 percent of the territory. Portugal plans cover both island groups, the Azores and Madeira, on the same three networks.

ANACOM, the telecom regulator, found rural areas weaker than the cities in its road tests of 2019 and 2020, with the Alentejo among the weakest regions. On the islands, some of Madeira's road tunnels had no coverage from any operator in ANACOM's 2022 drive test. No eSIM changes that.

Portugal has no national roaming, so a local SIM stays on one network, which means only a travel eSIM can switch between two or three of them. Airalo, Saily and Holafly use all three networks, Roamless uses MEO and NOS, Jetpac uses Vodafone and NOS, and Ubigi uses MEO alone. In the cities and on the coast the difference is small; on rural roads, three networks beat one.

On the Lisbon metro, MEO has had 5G in the Red line's tunnels since 2023, so Ubigi, on MEO alone, works underground on that line.

eSIM or a local SIM card in Portugal?

For most visits, an eSIM. A local prepaid SIM card makes sense when you need a Portuguese number or stay for months.

A Portugal SIM card from NOS or Vodafone comes with a local number for calls and SMS, which no travel eSIM in this article gives you. You buy it in the operators' stores in the cities or at the Vodafone shop at Lisbon Airport. A SIM card for Portugal stays on its operator's network for the whole trip.

For a week or two with WhatsApp for calls, take an eSIM and keep your number. For a season in Porto, or when you need a Portuguese number for local calls, get a local SIM in a store on your first day. The full comparison is in eSIM vs SIM card for travel.

Best eSIM for Portugal and Spain

If your trip covers Portugal and Spain, buy one Europe plan, not two country plans. Every single-country plan here works only in its own country, so Saily's Spain plan gives no data in Portugal, and Saily sells a Europe plan for trips with both. On price the winner is Ubigi's Europe plan, with Portugal on MEO and Spain on Orange.

Roamless credits are valid globally, so one balance works on both sides of the border.

There's a second reason for a two-country plan. Near the Spanish border a phone sometimes connects to a Spanish network whose signal is stronger at that spot, as ANACOM warns. With a Portugal-only plan that means no data until you pick the Portuguese network by hand in the settings. With a Europe plan you won't notice.

For a longer route, pick every country of your trip on our homepage or compare Europe eSIM plans.

My verdict: the best eSIM for Portugal in 2026

Start with where you're going. In Lisbon, Porto and along the Algarve coast every eSIM here works, so buy on price and features. For the interior and hiking days, take a plan with all three networks, Airalo or Saily. Where one network is weak, another may still have signal.

My top recommendation for most trips is Airalo, on NOS, Vodafone and MEO with 5G, with a cheap 10 GB plan you can buy months ahead. It covers the islands too. I recommend Saily for unlimited data because it gives the most full-speed data per day. I recommend Roamless if you want to pay by the gigabyte, since the credits never expire.

Go with Ubigi if your trip continues into Spain or beyond, with one plan for Portugal, Spain and most of Europe. And go with Jetpac if running out of data is your worry.

Whichever Portugal eSIM card you choose, the routine is the same, because you buy online at home, install on Wi-Fi, and the plan starts when you land in Portugal.
