Default [Q] keep unlimited data on AT&T?

Hello. I'm currently using an ip5 and will be upgrading to the note 4. Anyone who was on an iphone and upgraded to the note 3 on att, were u able to keep ur unlimited data? (That is if u had unlimited data) I really don't want to lose it and if someone has found a work around for this I would gladly appreciate any info!

I tried acting as if I was gonna upgrade to the note 3 online and when it came to the data portion, I wasn't able to find a way to keep it. I'm planning on going to best buy to purchase the note 4 if that matters. Thanks again!
