This is a device that boosts your cell signal using your broadband connection. If, like me, you have a weak, spotty or no cell connection at your home, this works great! I'm moving and will no longer need this so I'm selling. It works really, really well.
Asking $80 shipped
I'll deactivate it and all you need to do is go online and activate it to work with your account (instructions can be found in link above)
