BNESIM does not provide a true unlimited data eSIM for Portugal. The plans that carry the “Unlimited” name, such as Portugal Unlimited 10 days, offer 3 GB per day at full speed; after that data, the speed is reduced to 1000 kbps, which is a throttled limit rather than an unrestricted data allowance. Because of this throttling, these plans are not free or unlimited high‑speed data.
Travelers who need a larger, still‑constrained data allowance can choose one of BNESIM’s fixed data plans. For example, the Surf 100 GB in Portugal for 30 days gives 100 GB of 5G data that can be used within 30 days, and the Surf 100 GB in Portugal with no expiry offers the same data amount without a time limit. Fixed data plans are generally more economical unless the user expects to consume an extremely high volume of data.
