I don't have a data plan, so it costs me tons to use data, however I require it to be on to receive and sent MMS messages. Thus, I restricted background data to save me money, but considering that I will always have background data restricted, for the lifetime of the device, I wanted to remove the notification.
My device (if it matters) is a moto g turbo (xt1557) running stock 6.0.1
