Turn single plan into family, preserve $30/unlimited??

[hookem12387]

I plan to call AT&T tomorrow to find out if it's possible to do ts, but I thought someone may know. I need to add my sister to my acct and make it a family plan, but I really don't want to lose my data plan. Thanks if anyone knows

Call AT&T, they may do it but no one can really know unless they ask AT&T.
