How to Invite Friends and Voice Chat Using the Nintendo Switch Online App

With the Nintendo Switch Online app you can also invite friends who have the game to Private Battles, League Battles, Salmon Runs, and Splatfest Battles via social media and other services. When players are invited to a game, they'll get an instant notification on their smart device.

Important:

The app is currently compatible with the Splatoon 2 game.

All players wishing to use voice chat must download the Nintendo Switch Online app to a smart device and sign in using the same Nintendo Account they are using to play Splatoon 2.
