I have many friends in the States that I keep in touch with constantly but I have a really bad habit of not carrying my little telephone book around with me. Of course those are the times when I want or need to call them. I kinda remember the numbers but most times I’m not sure or get them mixed up, so what better way then to use an online phone book search to make sure that the phone number really matches. It’s pretty easy to use and goes by the state they are in and it’s absolutely free.
