simpleSIM does not provide a truly unlimited high‑speed data eSIM for Portugal. The plans listed as “Unlimited” are fixed‑data bundles that each give 1GB per day and reduce speed to 512 kbps for Portugal after the data cap is reached.
For travelers who need larger data allowances, simpleSIM offers fixed‑data plans such as the 50GB + Calls & Texts for 30 days or the 20GB + Calls & Texts for 30 days (or 14 days for the Europe version). These plans allow full‑speed data up to the specified amount and can be more cost‑effective unless the user is an extremely heavy data consumer.
