Hi Mike, For Hn9000 users the refill of allowance during the first 10 days of service is to allow you to download all necessary updates for devices in your home. That way your allowance can be used normally there after. Many times when someone is getting service for the first time, or switching, there could be a time when you have no internet. Any device off the net for a few days will most likely have some type of update needed to get it up to speed. This grace period is in place with that in mind. I hope this clears it up for you. Thanks, Chris
