We need daily usage alerts with define thresholds. I can;t tell you how many times one of my family members thinks they are on WIFI while watching youtube videos only to find out that the modem/router in the home was down and they have burned up 300MB just like that. We need to be able to set alerts based on daily usage. Overall usage alerts is nice, but really does;t do anything for me.
Please consider adding this feature. Too many times I have gone over the XL limit due to this situation.
