I am a prepaid customer and I received an offer by SMS with a promo code to get a postpaid deal for 12GB at 30$ a month. I would like to sign up for this. When I follow the instructions in the SMS message it doesn't work. I get the below message.
"Sorry, it looks like this promo code isn't eligible with the items in your cart."
If you can assist me that would be great. Thanks.
