I been reading on the forms lately and starting to come across this more often. We all hear of parents getting cell phone for their children who don't use the data within their means. In which turn can cause excessive ammounts of data overage. So giving the control to the client to enable a data cap through self serve would be a good idea. This would eliminate billing discrepencies and also allows the client to have even more control of their useage. Give this a +1 if you agree. I hope this gets a lot of feedback.
