The eSIM worked perfectly, just
The eSIM worked perfectly, just make sure you follow instructions. You have to turn in global roaming in settings to enable eSIM on landing. I got the 4GB for 2 weeks which was plenty, there is plenty of free wifi in hotels and trains shops and stations for mindless scrolling, rest of the time only really use it for maps. Set up phone so it only uploads photos to the cloud when on wifi and you won’t need more
