Well professionally speaking it is not a good idea for us, as women, to hand that kind of information out. At least that is what I have been told by my professional readiness teacher. If these are you SERIOUS BUSINESS business cards then you should just have an email address and any other information like your website. Only write your phone number on business cards when giving them to someone you trust. Also what I've been told. For class it was no big deal but that isn't the kind of information you want to give to a stranger. I hope my input was helpful.

You're not supposed to have your phone number on your business card :)
