Mobile data usage limits

[Android Question]

Hello,
on Android 4.0.4 "mobile data usage" warning (orange line) and limit (red line) I can set both to 0 MB.
On Android 4.1.2 warning I can set to 0 MB, but limit (red line) I can set minimum to 1 MB.

Maybe someone knows how to set mobile data usage (red line) to 0 MB on Android 4.1.2?

Thanks

I believe you can't set it to zero anymore, because you can do that by just turning off data yourself.
