Can you help me track down this girl I met last night.  She gave me her number, but it doesn't work

Unfortunately, there's nothing that can be done without more information. It could be that the number is wrong or that the girl has recently changed mobile service providers. The only way to know for sure is to find out more about the situation - like how you met, what type of phone she was using, and where she is from.
