Jetpac does not provide a truly unlimited high‑speed eSIM plan for Portugal. The plans that carry “Unlimited” in their name actually give 3 GB per day of high‑speed data; once that daily allowance is reached the speed is throttled to 1024 kbps. Because of this built‑in cap, choosing a fixed data plan can be a more cost‑effective option unless very heavy data usage is required.
For travelers who prefer a larger fixed allowance, Jetpac sells plans such as Portugal 40 GB for 30 days or Portugal 30 GB for 30 days, both of which provide a sizable data package without the daily limit or speed reduction associated with the “Unlimited” offerings. These plans give unlimited use of the allotted data while avoiding the throttling that occurs after 3 GB per day.
