Our recommended eSIMs for Portugal

Coverage in Portugal
Coverage is strong across Lisbon, Porto, the Algarve and the main regions, as travel eSIMs use Portugal's major networks. Remote interior areas can be patchier, as everywhere.
How much data do you need?
- ◆Light use (maps, messaging): 1–3GB per week.
- ◆Normal use (social, photos, some video): a 5GB+ plan with top-up.
- ◆Remote work or multi-country Europe: a larger allowance or a regional plan.
Getting connected on arrival
- 1Buy your plan before you fly, while you still have your home connection.
- 2Install the eSIM when prompted (scan the QR code or tap install in the provider's app), and label the line so it is easy to find.
- 3On arrival, turn the travel eSIM's data on and enable data roaming for that line.
- 4Set your home line to 'data off' so you are never billed for roaming, and keep it active for calls, texts and two-factor codes.

Does an eSIM work in Portugal?
Yes. Travel eSIMs connect to Portugal's major networks, with strong coverage across cities and the Algarve. Your phone must support eSIM and be unlocked.
Is an eSIM good for working remotely from Lisbon?
Yes — a data eSIM gives you a reliable connection independent of café Wi-Fi. For heavy remote work, a larger data plan is simplest.
Should I buy a Portugal plan or a Europe plan?
For Portugal only, a local plan is usually cheapest. If your trip crosses into Spain or beyond, a regional Europe plan follows you across borders.
