ANYTHING HELPS, need advice!

So my boyfriend is gone on the east coast for the summer and while over there his phone broke and because of lack of money, hasn't got a new one. Our only communication is through his dad's phone, but the last day and all of today I've tried to contact him and nothing. I've almost blown up his dad's phone and his Facebook is already full of me saying goodnight and good morning with no replies from previous times. Now it's almost been two days and I don't know what to do. Message his Facebook and risk seeming clingy or not do anything and risk seeming like I don't care? PLEASE anything helps!
