Welcome to the Best Buy Community forums.
Generally speaking, the buy-one-get-one promotions require you to sign up for a second phone line. The phone would need to be attached to that line for you to get it.
If you made this purchase in a store, you’d want to head back in to that store to see if you are still within the window to get that second phone added on. Sometimes they don’t need to be bought at the same time. I would encourage you to swing back by so they can look your account up and see what’s possible for you.
If you have any questions, or if there’s anything further I can assist you with, please let me know.
