Sim Local does not provide a truly unlimited data eSIM for Portugal.
All of its “Europe Unlimited” plans give 10 GB per day, which means the high‑speed data allowance is capped at 10 GB each day; after that limit is reached the speed is reduced. Because there is no plan that offers an unrestricted data cap, those labels simply indicate a large per‑day allowance rather than unlimited data.
If an unlimited experience is desired, travelers can choose one of Sim Local’s fixed‑data plans instead. For example, the Orange Holiday Europe 500 GB plan allows 500 GB of high‑speed data over 90 days, while the Portugal 40 GB + EU Roaming plan gives 40 GB for 15 days. These fixed‑data options are generally more cost‑effective for users who need substantial data but do not require truly unlimited usage.
