Best eSIM for Americans visiting Portugal

19 October 2026·Proost eSIM

Portugal has become one of Europe's fastest-growing destinations for Americans

Lisbon's trams and viewpoints, Porto's wine cellars, and the Algarve's beaches offer a European trip that feels a little different from the usual France-Italy circuit, often at a lower cost too.

The Europe eSIM covers Portugal — plus 30+ other countries

A Proost Europe eSIM covers Portugal alongside Spain, France, Italy and dozens of other countries. If Portugal is one stop on a wider European trip, one plan covers your whole itinerary.

Portugal's mobile coverage

Portugal has strong 4G coverage across Lisbon, Porto and the Algarve region. Rural inland areas can occasionally have patchier signal, though most tourist routes are well covered.

How much data for Portugal?

5GB — one week, moderate use

10GB — two weeks, regular maps and social media, especially if combining Portugal with other European stops

The AUD price advantage for Americans

Proost prices all plans in Australian dollars, which typically means Americans pay less in USD terms than the listed price suggests.
