Online dating... Should I give her my phone number?

Were both 17 and she can't skype. I can't meet her.
we both want to wait till uni till we meet but I want to hear her voice.
We met a year ago-ish.
I'm thinking about giving her my phone number... What's the worst that can happen (because I've never dated online before and need help)?

Put the internet to work for you.
