Dropped iPhone now cellular and wifi don't work

I went through the phone making sure all connectors where good and they were.

It is an att phone and I get no cellular signal and no wifi signal. I actually can't seem to turn wi-fi on now it is just greyed out.

Is there anything to look at that would effect both of these?
