Eskimo eSIM does not provide a truly unlimited high‑speed data plan for Portugal.
All plans that contain “Unlimited” in their name actually offer 1 GB of high‑speed data per day; once that limit is reached the speed drops to 512 kbps.
They do allow tethering and are available from 1 day up to 30 days in validity, but the data cap is fixed at 1 GB per day.
Travelers who need more data can choose from Eskimo eSIM’s fixed data options. For example, the Portugal 10 GB plan is valid for 730 days and the Global eSIM 30 GB plan for 730 days, both offering high‑speed data only, without any speed reduction once the data limit is reached. These fixed data plans are often more cost‑effective unless a user requires ultra‑heavy data usage with no throttling.
