Wisco, you are not paying for a current
iPad connection until such time as you activate it. This is separate from your iPhone contract. It is in addition to your 3G service month to month that you may also activate fro your iPad. Those are three different, unique services. The mobil hotspot function, at $45, drives your computer and other devices like your iPad2
If you have the $45 mobil hotspot activated and are also paying your $25 iPad 3G charge you are double paying. Your iPhone contract only gives you service for your phone. Your iPad monthly usage 3G fee drives only that singular iPad.
