I once had a maximum of 6 at a time in my phonebook, but there are more. Names of girls I can remember are: Ana, Jojo, Lily, Taylor, Tami, Tania, Vikky. They do not affect game completion, and you can continue to do this after 100%.

Free save (without advancing time) and heals you. Doesn't really matter to people who don't care about their game time or how many times they saved though.
"Wait a minute; do you just get these from dancing in clubs?"
Yes, if you don't dance perfectly you sometimes get a girl that will go into the bathroom with you. You get her phone #, the phone # is good for 3 booty calls before she dumps you. --- Try Ubuntu Wii, 360
That explains a lot! I had one (named Domino) and had about 3 booty calls then I got a random text saying "don't call me loser." I was like WTF? lol
