eSIMCard does not provide a genuinely unlimited data eSIM for Portugal. All of its plans that carry the name “Unlimited” actually give a fixed amount of high‑speed data – for example 1GB or 1GB per day – after which the speed is reduced to 500kbps. Because the data allowance is limited, the plans are not truly unlimited.
If you need more data you can choose one of eSIMCard’s fixed‑data plans. For example, a 50GB plan is available for 30 days at a price of $31.39 USD, and a 100GB plan is available for 90 days at $191.83 USD. These high‑cap plans provide a larger and constant data allowance and may be more cost‑effective for travelers who need substantial data usage in Portugal.
