How much eSIM data for 7 days in Portugal?
For 7 days in Portugal with normal daily use, TripUtils estimates 3–5 GB. A 5 GB plan is the usual buffer. Not a live price. Navigation in Lisbon’s hills and island hops still fits the normal GB band unless you stream video on mobile. Type C/F at 230 V matches much of continental Europe.

What to do next
If your home SIM is an EU/EEA plan, Portugal is often already included. Check roaming first. If you still want a travel eSIM, pick a Saily plan at or above 5 GB for Portugal.

Assumptions and sources
Light 0.20 / normal 0.50 / heavy 0.95 GB per day, plus optional extras, plus about 20% buffer. No live retail prices.
Summer in Lisbon, Porto and the Algarve lifts stays; data use follows the calculator, not the beach.

Common questions
Is 5 GB enough for 7 days in Portugal?
Navigation in Lisbon’s hills and island hops still fits the normal GB band unless you stream video on mobile. Type C/F at 230 V matches much of continental Europe. The 3–5 GB estimate plus buffer lands on 5 GB. Hotel Wi‑Fi is not counted. Streaming video on mobile is the usual reason to go larger.
Should I roam in Portugal instead?
Portugal is inside EU roaming for most EU/EEA plans. An eSIM is a backup when the home cap is small or the SIM is British/Swiss/other non-EU.
Do you show live Saily prices?
No. Live prices belong on the provider site. The numbers on this page are a data-size estimate only.
