Setting your favourite song as a JioTune is quick and easy. 😃 First, make sure you're connected to cellular data on Jio network. Then tap the (•••) menu to the right of any song, and select "Set JioTune". If the "Set JioTune" option is greyed out, then that song isn't available as a JioTune just yet.
You’ll also see a button on your player that says “JioTune Available” or “JioTune Unavailable” for the song you’re currently playing.
