Portugal travel data eSIM
What is a Portugal eSIM?
A Portugal eSIM gives travelers a ready‑to‑use data connection the moment they step off the plane. With the eSIM already installed at home, you arrive in Lisbon, Porto, the Algarve or the islands and can instantly access maps, translation tools and local transport apps without swapping a physical SIM. It lets you stay online for navigation, bookings and sharing moments while you explore Portugal’s historic streets, coastal towns and scenic landscapes.
In Portugal the eSIM links to Vodafone 5G and NOS 5G networks, so your data flows through whichever operator you are connected to. The plan’s data allowance is deducted only after you first connect while in Portugal, and you can choose from 1 GB to 20 GB options that run for either a week or a month, depending on your itinerary.

Local networks
Which networks you connect to in Portugal
Connecting through Vodafone 5G or NOS 5G lets you tap into the operator’s network infrastructure across mainland Portugal and the Atlantic archipelagos. Coverage depends on the specific operator’s network in the area you are visiting, so you’ll have access to mobile data wherever the chosen network is present, supporting everyday online tasks during your stay.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operators does the Portugal eSIM use and what does that mean for a traveller?
The eSIM connects to Vodafone 5G and NOS 5G networks. This gives you access to the data services those operators provide while you are in Portugal, allowing typical mobile internet use.
Does the Portugal eSIM also work in a neighbouring country of Portugal?
It is a single‑country plan valid only in Portugal. For travel that includes Spain or other nearby nations, regional multi‑country plans are available.
Which plan size suits a trip to Lisbon and Porto?
As a rough guide, a 5 GB or 10 GB 30‑day plan often covers two major cities like Lisbon and Porto, depending on your typical data usage for navigation, apps and occasional streaming.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
