I have previously gotten a physical sim at the airport and topped it with bitrefill (if you want to pay with sats!) but I know eSIMs work too 😇

You'll def need cash (and/or card) since not everyone is keen to accept bitcoin yet (although it's always growing, I always make a point to ask haha) Definitely load up a lightening wallet. 
In the city you'll be able to Uber anywhere pretty easily, maybe you want google translate or something for outside the city if you need to get creative to find a ride 😋 

I'll see you there!!
