the $100 card is only for people who are upgrading there line from a standard phone to a smart phone. they gave me a $100 instant discount when I upgraded to a smart phone about 6 years ago. And they didnt even take your standard phone back then. the idea is to get more people on data plans. they offer this $100 for a few months then take it away, then bring it back...etc... You would think they would be offering more than $100 by now since its been the same deal for at least 6 years.
