## What this listing is
This is Airalo's eSIM page for Portugal. An eSIM is a data plan you install on a phone that supports it, so you can be online when you land without buying a physical SIM. The page is titled "Portugal eSIM, from 4.00 €" and sells plans for Portugal only; broader plans are linked separately.
## The plans listed
Under the Unlimited filter the listing showed these packages when we read it:
- 3 days: 10.50 € - 5 days: 17.50 € - 7 days: 25.00 € - 10 days: 31.50 € - 15 days: 44.00 € - 30 days: 63.00 €
That is 10.50 € for 3 days at the short end and 63.00 € for 30 days at the long end. Worked out per day, the best value on the list is the 30-day plan at about 2.10 € a day, and the shortest plan costs about 3.50 € a day. The page also has filters for data-only, unlimited and fixed-data packages, so a smaller fixed-data plan may be cheaper than anything above.
## Coverage beyond Portugal
If your trip crosses borders, the page points to European Union and United Kingdom eSIMs from 4.00 €. These are separate products, so compare them against the Portugal plans before you buy.
## Network and setup
The page does not name the network in the text we read; open the listing to see which network a plan uses. Airalo says installation takes minutes and that you can install before you leave, which matters because you need a connection to download the eSIM profile. Check that your phone supports eSIM and is not locked to a carrier using the compatibility link on the page.
## Support
The page states 24/7 support in several languages, including chat on WhatsApp, and an app in 53 languages. Airalo also says over 30 million people use it; that is the company's own claim, not ours.
## When it fits
It suits a short city trip, such as a few days in Lisbon, where you want maps and tickets on your phone from arrival. If you use very little data, compare against your home plan's roaming price first.
