For most trips to Portugal, a travel eSIM is the simplest choice. You install it by scanning a QR code, keep your home SIM active for calls and bank codes, and choose a plan length from 3 to 30 days. Check that your phone is unlocked and supports eSIM before you buy.

What a Portugal eSIM costs
The cheapest published plan among the Portugal eSIM plans is 1 GB valid 7 days. From there the data plans step up to 2 GB for 15 days, then 3 GB, 5 GB, 10 GB and 20 GB, each valid 30 days. Prices change, so check today’s prices on the live product page; per gigabyte, the bigger plans usually work out cheaper.
Network
The supported country is Portugal, and the live product page shows the current network details. Real speed depends on local coverage and your handset. Portugal is covered as one country on this plan, which in practice means Lisbon, Porto, the Algarve, and the main routes between them. This is not an EU-wide plan, and it does not cover Spain: a day trip from Porto to Vigo or from Faro to Seville needs its own plan, even though both countries are in the Schengen area. The product page does not publish a coverage map, so treat remote stretches of the interior as outside the guarantee.
How much data you actually need
Maps, chat, and transport tickets sit inside 1 GB for a short city break. A week of moving between Lisbon, Porto, and the Algarve with daily photo uploads is the 3 GB or 5 GB plan, and a month of travel or hotspotting is 10 GB or 20 GB. Cafe and hotel Wi-Fi is widely available in Portuguese cities, so the larger buckets here are more about hotspotting and video than about basic navigation.
Unlimited data
Unlimited plans are listed on the same product page, for 3, 5, 7, 10, 15 or 30 days. Compare them with the 10 GB and 20 GB plans, which run for 30 days: for maps, chat and photos a data plan is often enough, while daily streaming or hotspotting is where unlimited earns its keep. Check the plan details on the product page before you choose.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the travel eSIM line. iPhone: Settings, Mobile Data, pick the travel line. Android: Settings, Network, SIMs, set mobile data to the travel eSIM. Do this before you leave the airport Wi-Fi.
Arrival and transit
The main gateways are Lisbon (LIS), Porto (OPO), and Faro (FAO) for the Algarve, with Madeira (FNC) and the Azores (PDL) reachable by domestic flight. Install the eSIM on hotel or home Wi-Fi before the flight, then switch the data line on after you clear arrivals. You do not need a local shop or a passport photo for this plan.
Install
- Buy the plan and open the QR code in the order email while you still have Wi-Fi.
- On the phone, add an eSIM and scan that code. Label the line “Portugal”.
- After landing, set mobile data to that line and leave your home number on for texts.
Phone compatibility
The phone must be carrier-unlocked and eSIM-capable. iPhone XS and later, and recent Samsung Galaxy and Google Pixel models, qualify. A locked handset will not take the QR code. Check the lock status with your home carrier before you pay.
FAQ
Q1: How much is the cheapest Portugal eSIM?
The smallest plan is 1 GB, valid 7 days. Prices change, so check today’s price on the live product page.
Q2: Which network is on the plan?
The live product page shows the current network details. The supported country is Portugal.
Q3: Does it include calls and SMS?
No. It is a data plan, with voice calls only through apps such as WhatsApp or FaceTime. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
Don’t plan around a specific speed. Real speed depends on local coverage and your handset.
Q5: Can I install it after I land?
Yes, if you can reach Wi-Fi. Installing before the flight is simpler, because the QR download needs a connection.
Q6: Will it work outside Portugal?
No. This is not an EU-wide plan, so a Spain day trip from Porto, Faro, or Lisbon needs its own plan.
Q7: Is there an unlimited option?
Yes. Unlimited plans are listed separately on the same product page, for 3 to 30 days.
Q8: Can I share it as a hotspot?
Yes, within the data allowance. Hotspot traffic counts against the same gigabytes.
Q9: What if the QR code fails?
Use the manual activation code in the same email. The phone still has to be unlocked.
Q10: When was this guide checked?
On 24 October 2026, against the live Portugal eSIM product page. Prices are not listed here because they change; see the product page.
Bottom line
For a week in Portugal, the 1 GB / 7 day plan is the entry point, and the 3 GB / 30 day plan suits most travellers. A city-hopping trip with daily uploads is 5 GB, and a month of heavier use is 10 GB or 20 GB. Check today’s prices on the live product page before you buy.
