How much traffic is created by simfy and how can I change it?

Streaming and downloading (offline mode) amounts to about 1 MB of data traffic per minute, depending on the song. To reduce the traffic while you're on the go, ie. on your mobile phone, we recommend that you download selected songs with WLAN beforehand. This can be done by simply designating the playlist as "Offline" with a simple click. The blue-highlighted song will then be played from a local copy. When you switch the simfy smartphone app to offline mode, all data traffic is on hold until you decide to switch it back to the online mode. This prevents expensive connection costs, your mobile internet connection won't be slowed down if your provider's volume is exceeded, and you won't experience any loss of connection if your reception is weak.
