Ok; thanks. I'm just not up on the plans. I'm not sure how the mobile share advantage plans differ from or work in conjunction with the unlimited data or the international day pass.
I've got our two phones on a share plan with fairly small data amounts (4GB). I'm not sure what I've got at Verizon for the two iPads but we pay $30 / month for each of those.
Sigh. I was hoping ATT had simplified things a bit but it doesn't seem so to this rube!
