Which eSIM is the best value for Portugal?

All 6 plans here last 30 days with at least 5 GB, so value turns on price, top-up and refunds. Because plan length is equal, you can compare the rows directly. Yesim is shown first as Editor's Choice, and the rest follow the column order.

What to check before you pick a Portugal plan

Every row in the table offers the same validity, so no plan is shorter than another. Next, look at how each provider handles top-ups if you run low. Then read the refund terms, since an unused plan only has value if it can be returned. Our guide to data needs helps you judge whether 5 GB is enough.

Where Yesim fits for a 30-day stay

Yesim offers the same 30-day length as the other rows. It works on a pay-as-you-go basis, so you can add data as you need it. Unused plans qualify for a 30-day refund, which lowers the risk of buying early. On price, Yesim sits above the median of $10.01 but below the top of the range. We earn a commission if you buy through Yesim links. Full details are in the Yesim review.

How prices spread across the 6 providers

Prices in the table run from $4.67 to $11. eSIMCard holds the lowest price, well below the rest of the field. Airalo, Saily and Nomad sit close together, just under Yesim. Nomad lands on the median, so it marks the middle of the table. Ubigi is at the top of the range. If price matters more than refund terms, the gap between the middle rows is small.
