What are you looking to do? Link to an existing node or use the "node in the phone"?
You can setup a wallet and send sats to yourself for the later.
Anyone knows how to use new nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 app? Any tutorial?

I don’t even know what to do from this first page 😂 
Quick start should walk you thru
Let’s try …
Quick Start sets up the embedded node. If you want to connect another wallet or your own node you should use Advanced Set-Up.
nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 Maybe that’s a button that could be clearer. Like, “Connect a Node or Wallet” or something.
Thank you, I will try …
