NOS gives the most data for the money at 55 GB for EUR 10, sold in the arrivals halls at Lisbon and Porto. If you would rather not queue after landing, a Saily eSIM activated before departure is the faster route.
- NOS gives the most data for the money: 55 GB of 5G for EUR 10.00 over four weeks, sold in the arrivals halls at Lisbon and Porto.
- MEO is the same EUR 10.00 for 50 GB but requires registration in store; Vodafone's tourist pack is EUR 20.00 with calls and texts included.
- Kiosks sit just past the customs exit in Lisbon Terminal 1 and on the ground floor of Porto arrivals.
- Away from the airport, the operators' own shopping-centre stores and Relay newsagents sell the same packages.
- Want connectivity the moment you land with no queue? A pre-activated eSIM at around USD 9.99 for 5 GB does it.
What to buy as soon as you land
Portugal has good availability of data packages at competitive prices, so the only real choice is physical or virtual.
- If your phone supports eSIM, buying a virtual card before you travel is the fastest route - no queueing at a kiosk after landing.
- If not, a physical prepaid SIM at the airport works fine.
