Best eSIM for Portugal in 2026: what a remote worker should actually buy
Nomad and Ubigi suit a laptop hotspot, Airalo and Holafly sell unlimited data with a cap, and a 10 euro local SIM beats all four. An EU SIM may already roam free.
Published . 6 min read.
The best eSIM for Portugal in 2026 depends on how you use data. Nomad and Ubigi sell fixed gigabyte eSIMs built for tethering a laptop and tracking usage. Airalo and Holafly sell unlimited eSIMs that slow down or cap sharing after a daily threshold instead of a total. A local NOS, Vodafone or MEO prepaid SIM undercuts all four once you accept a passport check in a shop, and Woo, Uzo, Moche and Digi undercut them again from week two. If you already carry an EU or EEA SIM, none of this may apply to you at all. Every price below comes from the provider's own page, checked on 26 September 2026.
Which eSIM works best for a laptop hotspot in Portugal?
Nomad answers this most directly for Portugal. Its own page states that Nomad's eSIMs support tethering and hotspot, so the data you buy covers a laptop the same way it covers a phone. Nomad runs on the Vodafone or MEO network and prices a fixed 10 GB for 30 days at EUR 13.94, with no 15 day tier: the nearest short option is 7 days of unlimited data at EUR 21.78. Ubigi states the same policy in different words: its Portugal plan page lists "data sharing allowed" on every tier, including a 25 GB, 30 day plan at USD 28.00 on the MEO (TMN) network. Neither Nomad nor Ubigi advertises unlimited data on its fixed tier, so a laptop doing video calls will use the allowance faster than a phone alone: buy enough gigabytes rather than assume a plan covers a full working month.
How much do the main Portugal eSIMs cost for 15 and 30 days?
Unlimited and fixed data eSIMs are not priced on the same terms, so the table below keeps each provider's own wording rather than forcing a false match.
| Provider | Data | 15 days | 30 days | Hotspot |
|---|---|---|---|---|
| Airalo | Unlimited, full speed until 3 GB a day, then 1 Mbps for the rest of that day | EUR 43.00 | EUR 62.00 | Included, no limit on the number of devices, same daily cap covers hotspot use |
| Holafly | Unlimited, hotspot shareable at 1 GB a day (adds up over the plan) | USD 50.50 | USD 73.90 | Included, capped at 1 GB shared a day, plus a permanent 1 GB of backup data every month |
| Nomad | Fixed data (no 15 day tier; 10 day unlimited shown) | EUR 28.75 for 10 days, unlimited | EUR 13.94 for 10 GB | Included, tethering and hotspot explicitly supported |
| Ubigi | Fixed data (no 15 day fixed tier; 15 day unlimited shown) | USD 34.00, unlimited | USD 28.00 for 25 GB | Included, stated as data sharing allowed |
Airalo's speed drops to 1 Mbps for the rest of each 24 hour window once you pass 3 GB, timed from activation rather than midnight. Holafly adds a permanent 1 GB of backup data every month on top of its 1 GB daily hotspot share. At the XE mid market rate checked on 26 September 2026 (1 US dollar equals 0.878 euro), Holafly's 30 day plan runs about EUR 65 and Ubigi's 25 GB plan about EUR 25, both convertible with the Currency Check.
Is a local prepaid SIM cheaper than an eSIM in Portugal?
Yes, once you accept a passport check at a counter, a Portuguese prepaid SIM beats every eSIM above on price. NOS's own mobile tariffs page lists its Like plan at 55 GB for 10 euros a month, with 5G and no commitment. Vodafone's Ready page matches it: 55 GB for 10 euros or 95 GB for 15 euros, billed every 4 weeks rather than monthly. MEO sells by the week instead of the month: a 2026 SIM buying guide checked on 26 September 2026 lists 50 GB for 2.50 euros and 100 GB for 3.75 euros, which suits a short stay better than a monthly plan. All three ask for a passport to register the SIM. For the full picture on where to buy, airport prices and topping up, read how much is a prepaid SIM in Portugal.
Which low cost brand beats them all after week one?
Woo and Uzo do. Woo, the no commitment brand under NOS, lists 100 GB with 2,500 minutes or texts for 5 euros a month, open to sign ups until 30 September 2026 at last check: confirm the live cutoff before counting on it, since this kind of offer usually rolls forward rather than actually ending. Uzo, MEO's equivalent brand, prices the same 100 GB at 5 euros with no contract, and unlimited data at 7 euros. Moche, Vodafone's version, prices by the week: 200 GB for 2.50 euros and 500 GB for 3.50 euros, roaming included, no lock in. Digi's separate mobile line runs 5 euros for 50 GB and 7 euros for 150 GB, or unlimited from 6 euros, 5 euros bundled with Digi home internet. The coworking and internet guide covers all five brands alongside fibre and desk prices.
Does an EU SIM already roam for free in Portugal?
Yes, for most of Europe. The EU's official consumer page states that a person travelling within the EU, the EEA or a short list of neighbouring countries pays domestic rates for calls, texts and data on their home SIM, a rule known as roam like at home, with no end date attached. Operators can apply a fair use data limit, set from a wholesale cap of 1.30 euros a gigabyte in 2025, falling to 1 euro from 2027. An Irish, French or Spanish SIM already works in Portugal at home prices, and keeps working across the border into Spain. It does not help a US, UK, Australian or Canadian SIM, since none of those sit inside the EU or the EEA: for that passport, one of the options above still applies.
Do you need your passport to buy a SIM or eSIM in Portugal?
Only for a physical SIM bought in a shop. A 2026 buying guide confirms that NOS, Vodafone and MEO ask for a passport to register a prepaid SIM at the counter, whichever brand sits underneath it. None of the four international eSIMs above works that way for Portugal: Airalo's own help centre says identity verification only triggers in some countries, shown as a clear "verify your identity" step before purchase, and Portugal does not trigger it, so checkout needs only an email and a card. Holafly, Nomad and Ubigi work the same way on their own plan pages: no document upload and no shop visit, and the eSIM's QR code arrives by email as soon as payment clears.
Which SIM or eSIM should you actually buy?
Match the plan to the trip rather than the marketing word unlimited. Work through the choice in order.
- If you already carry an EU or EEA SIM, keep using it and skip everything above; the roaming section explains what still applies to you.
- If you are staying under two weeks with a laptop in daily use, take Nomad's fixed 10 GB or Ubigi's 25 GB: both cost less per gigabyte than an unlimited eSIM and both state a clear hotspot policy.
- If you would rather stop counting gigabytes for a short trip, take Airalo, accepting the 1 Mbps floor after 3 GB a day, or Holafly if a 1 GB daily hotspot share is enough.
- If you are comfortable showing a passport in a shop and staying past the first week, buy a NOS, Vodafone or MEO prepaid SIM on day one, then move to Woo, Uzo, Moche or Digi once you know you are staying.
Check how many days your entry allows with Visa Check for Portugal before paying for 30 days you will not use. For the wider cost picture, start with Portugal for digital nomads, and read Digi against MEO fibre, priced both ways and Porto coworking after Porto i/o for the connection and the desk that come next.

Frequently asked questions
Which eSIM is best for Portugal?
It depends on how data is used. Nomad and Ubigi suit a laptop hotspot: both state tethering is allowed with no separate cap, and their fixed gigabyte plans cost less per gigabyte than an unlimited eSIM. Airalo and Holafly suit someone who wants to stop counting data, accepting a daily speed cap or hotspot cap instead. All four were checked on their own pages on 26 September 2026.
Can an eSIM be used as a laptop hotspot in Portugal?
Yes, on every provider checked here, but the limits differ. Nomad and Ubigi state tethering is allowed with no extra cap beyond the plan's total data. Airalo's unlimited plan allows hotspot use within its 3 GB a day fair use threshold, after which speed drops to 1 Mbps. Holafly caps shareable hotspot data at 1 GB a day, on top of a monthly 1 GB backup allowance.
Is a local Portuguese SIM cheaper than an eSIM?
Yes. NOS and Vodafone both price 55 GB at 10 euros a month or per 4 weeks, and MEO sells 50 GB for 2.50 euros a week, all far below an international eSIM's 15 or 30 day price. The trade off is a passport check at the counter, which none of the four eSIMs above require for Portugal.
Does an EU SIM roam for free in Portugal?
Yes. Under the EU's roam like at home rule, a SIM from another EU or EEA country uses calls, texts and data in Portugal at home country prices, subject to a fair use data limit. The rule also covers travel onward into Spain. It does not extend to a SIM from outside the EU or the EEA, such as a US, UK, Australian or Canadian SIM.
Do I need my passport to buy a SIM in Portugal?
Only for a physical prepaid SIM bought in a shop: NOS, Vodafone and MEO all register the card to a passport at the counter. International eSIMs work differently: Airalo's own help centre confirms identity verification only applies in some countries, and Portugal is not one of them, so checkout needs only an email and a card.
