How do I set data usage limit on android 5.0.1?

[AC Question]

I know how to set it on android 4.4.2, but the 5.0.1 does seem to have it.

It could be a bit different in your phone but try something like this. Go to settings - Data Usage and switch cellular data on. The option to set the data limit should appear after that. Press ok and slide up or down the bar on the graph.
