Have fun! The speed is rather fast for a phone modem. It loads webpages nice and fast. Very nice for using when you can't find a WiFi connection.
Note: If you DON'T have a data plan, this will cost you $2/MB! Also, the Vcast Vpak does NOT give you unlimited data for this service.Note 2: This is AGAINST the Verizon TOS, and could get your service TERMINATED. Use at your own risk!
