I remember seeing several threads on here discussing how you can use assumption of liability to get someone else's unlimited data line they no longer need. I don't have that, but I do have a $60/mo 20 GB plan on an air card that I'm likely to no longer need. It's not under contract anymore and I figure it'd be worth handing over (or maybe selling) to someone else since an equivalent plan would run you more than double on a More Everything plan. I'm just not sure how doing AoL transfers work to do that.
