That's the day I returned mine, and that's also the day (later in the afternoon) they announced the ability to even get a loaner phone. Idk if my original EIP is open or closed. No idea. All I know is I have a replacement device, S7 Edge that may or may not be a loaner phone...lol. Woooooooooooo!
You can check under your billing area on your account. Login, go to billing, and the EIP at the bottom. It shows active and they billed me the monthly cost this month on my bill. I am waiting for them to remove it before I pay since .. I returned the phone a while ago so I have no idea how it is open still.
