I had the airave before, its ok but overall it still sucked, I expect the airvana to be similar. Yes, you still get charged for minutes even though its really using your own internet. Also, you need to set it up so that only your phone number and people you know can use it, especially if you live in an apartment or else everyone near by can use it and it will slow down your internet connection.

If you download alot or stream netflix, the airrave/airvana will get missed/dropped/bad quality calls because of low bandwidth. I guess it better than nothing, but alot of times you get a false sense of confidence with these things.
