This extra data, how long is it good for?
Does it expire after one year, etc.?
The double data promotion is good at the very least through the end of your contract period from what the rep told me. It worked for me after I called the regular customer service number and asked for the Loyalty promo to double my data (3GB - 6GB) and I did all of this before I ever received the official email because I got a tip from a friend
