Question about new mobile share value plans pricing
So I am excited to sign up for the new 15 GB promo plan. I'm currently on 10 GB Mobile Share plan and am financing my iPhone on Next. I see the plans have been launched as of 08/15/2015 and the pricing for 15 GB has been matched to price for 10 but whenever I log in to change it in app or on myatt.com it shows me the promotion plans and the Canada and Mexico included but the 15 GB Promo plan keeps showing as $130 and not $100 as advertised. Anybody know why? Thank you.
