Thank you guys for your help.
I think the $40 is if you only had the BIS BB plan without any voice plan.
You need the BIS BB "add-on" plan for $20. It is the add-on that they will add to your existing family plan. It is definitely $20 ($19.95) and unlimited data. I just double checked my T-Mobile account.
