I called them three times trying to get this deal,
first time, CSR said that I don't qualify because I am only an AT&tCustomer for 3 months, I need to be with them for at least 4 months to get this deal, plus, I will only get 1000 min n/w not unlimited.
second time, CSR said that I can get the regional plan with 200 min + free nationwide roaming promotion, and they do have the additional 200min promotion, but it cannot be combined, plus, I will have to give up my unlimited n/w and can get 3000 n/w min (current promotion).
third time, CSR told me that the free nationwide promotion expired a month ago and my previous CSR probably just didn't know that it already expired, he can give me the 200+200min anytime, carry over the unlimited n/w, but I can't get free nationwide roaming. Then, I complaint that the csr told me it's still valid like an hour ago. He checked and checked, told me that he can't do it, but he offer to give me a $10 discount on my current plan.
Since I had the 600 digital advantage before, my plan now (if this discount that the CSR offered is true), then I am paying 39.99 for 600 anytime, unlimited n/w, free roaming in CA, AZ,NV, HI. I guess it's better than nothing. I am not gonna try again, it's too much trouble, and it seems like the CSR can just say whatever they want and if you are lucky, you can get a good deal.
