How do I disable mobile data (Lollipop, Finnish)?

[Panu]

I found these instructions:

http://www.spark.co.nz/help/mobile-data/device/sony/xperia-z/enable-or-disable-mobile-data-sony-xper...

But "Data Roaming" (in Finnish) is on top of the list and there is no "Mobile data traffic" option.

Thanks.
