On Samsung Galaxy: Settings → Connections → SIM manager → Add eSIM. On Pixel: Settings → Network & internet → SIMs → Add SIM → Set up an eSIM. Install before you arrive — activate data on landing.

For light use (maps, messaging, email) 1–3 GB over a week is usually enough. Social media and streaming on the go push that to 5–10 GB. Remote work or heavy video demands 15 GB or more. Unlimited plans are available if you'd rather not track usage. Plans we list for Portugal span 0.2–120 GB, so you can match the allowance to your trip rather than overpay.
