OSHEAWM, our valued customer's data usage concerns are our concerns too. Hearing that your data utilization increased for one mobile number on your account after adding the FamilyBase feature to it, is very unusual.
FamilyBase provides a hard-stop to restrict usage. I apologize for the inconvenience this has caused you. I'd like your assistance to make sure that the data setting option has been enabled on the specific mobile number for your account. This website link will assist you at: http://vz.to/2zjFbca.
I've also used the FamilyBase feature for my family's account. Changes to the Controls settings can be made at any time and as often as you like. The changes may take a few minutes to become effective.
Please keep in mind when you first set up restrictions for data, time, and/or purchase limits on the user's device, you'll need to turn the device completely off and back on again after the Control is saved. This will allow the Control to become effective. You won't need to do this if you make changes in the future. Please keep us updated.
