My wife has a new S5 neo Android 6.0.1 it had a "background data off" banner on the home page that she did not like so removed it and I assume turned data on without knowing. Since she has a pay per use plan I have now turned mobile data off and restrict background data use on, is it possible for the phone to use data set up this way? I have read that the latter may still allow some background data use with some apps but those comments were for earlier android versions, I can not find info for 6.0.1.

If mobile data is off the device can't use data. However during a restart it used to be possible to have a tiny data leak as the device was starting
Depends on the device really To be sure...add the data block to your account
