If you restrict your Airave to just your phone number(s) then no one else can access it. But if you leave it unsecured anyone can access it and if they do they will be using your minutes. When you look at your bill minutes are not broken down in any way that would show that you accessed the Airave or not. But if you wanted to test it out, it would be easy. Just don't use your cell phone within range of your Airave for one day. Then at then end of the day check your usage online and if there are phone calls showing up then someone else is accessing it and burning up your minutes. Its just like a wireless router. If you don't secure it your neighbors can use it.
