How to stream music on an iPhone 6 when not connected to Wi-Fi without using data?

Impossible, streaming is not possible without using data. If you want to play music without using data or connecting to Wi-Fi then you will need to download them or use an app that offers offline listening such as Spotify Premium. Apple Music is best for downloading music, free 3 month trial with unlimited downloads.

No. Streaming media requires some form of internet access. So if not Wi-Fi it would have to be data or vice versa.
