Hit my iphone on wall hard no sim

I was mad and i repeatly banged my iphone on my door kinda hard then i went to look at it and it still works but it says no sim on it instead of at&t -.- someone help me i already shut it off and it didn't do anything… I know stupid but ughh help
Note there's a sim card inside… Its saying there isn't

Dude. What the ***? At least hit a Nokia against a door instead

You have destroyed the board, and [possibly the sim as well, Rather than worrying about a trashed phone, you should be be considering getting psychiatric help. Anger management is needed.
