Thanks for all your replies! I was using it when i took a road trip down south and it worked great on the road for my laptop. I was on it for hours so i know i used alot of data so i will see if next months bill is different than the others.
I use it to allow my daughter to connect her ipod while we are travelling. No problems and nothing from VZ. Will be going on an extender road trip in October and will see what happens.
