- Heavy use — social video, streaming or hotspotting a laptop — plan for 2-3 GB per day or pick the largest plan.
- Match the validity to your trip length, with a day or two of buffer for delays.
How activation works
- Buy the plan and receive your eSIM by email within minutes.
- Install it from your phone settings while still at home — no store visit, no plastic SIM.

Tram apps, Comboios de Portugal tickets and a map through Alfama's unnamed alleys all want a signal. An eSIM means you land at LIS and ride the metro into town instead of paying roaming for the privilege of getting lost.
