I'm trying to change my plan online. When I click the new plan under account management, nothing happens. When I add a plan to cart it requires me to select a phone to checkout. I don't want a new phone, I just want to change my plan because I'm getting raped on data fees. It says changing online is free but to email for the change it costs 10$. However as mentioned above, nothing happens when I click to change my plan. Tried Chrome and IE.
