4S eSIM eSIM Data Plans for Portugal

4S eSIM does not provide a truly unlimited data eSIM for Portugal. All plans listed under the “Portugal Unlimited” brand give a fixed daily data allowance—such as 5GB/day for the Portugal Unlimited MAX – 5 Days plan—and reduce speed to 1000kbps once the daily limit is reached.

Customers who need a larger amount of high‑speed data can choose a fixed data plan, for example the Portugal Unlimited MAX – 15 Days plan that offers 5GB/day for 15 days or the Portugal Unlimited LITE – 30 Days plan that gives 2GB/day for 30 days. These fixed‑cap plans may be more cost‑effective for travelers who use a lot of data but do not require line‑up‑free high‑speed access.

4S eSIM does not provide a Portugal eSIM that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for the country. Travelers who need phone calls or text messages can use VoIP applications such as WhatsApp, Telegram or iMessage, which operate over the included data connection.

4S eSIM provides a range of single‑country data plans for Portugal. The total number of single‑country options offered by the provider is 36, while no multi‑country plans are listed for Portugal specifically. For all plans the price varies from approximately $1.45 to $1, 262.28, the data cap ranges from 300 MB up to 500 GB, and validity spans from 1 day to 365 days.
