I’m just back from this walk. I ordered an eSIM online from travel.vodaphone.com before I left and installed it. I then activated it when I landed in Portugal. It worked very well and was not very expensive.
There was one adjustment I needed to make whenever I crossed a national border, e.g...
I took a Sony RX100 m7 and was happy with the results. It is very small and light but has a 24-200mm zoom. The 200mm zoom enabled some shots that would have been impossible with a phone.
