Listen to Music
If you subscribe to Apple Music or even Spotify, you can stream your favorite playlists, podcasts, and radio stations to your cellular or Wi-Fi-connected Apple Watch.
Naturally, Apple Music has supported this since the first cellular-capable Apple Watch was introduced in 2017; It took a bit longer for Spotify to get on board.
While having a cellular or Wi-Fi connection will give you access to your entire Apple Music or Spotify catalog, both music services also offer offline playback, so you can take a few of your favorite tracks with you to listen to even if you don’t have a cellular model, or if you simply don’t want to use up your data plan.
