Can I still put a SIM card in my iPhone?

Ok so basically I was taking out my SIM card from my old iPhone 3GS. I got the tray thing out (or whatever it's called). But when I put it back I put it in the wrong way and it got stuck and I ended up snapping it when I tried taking it out

Depends if you got the other half of your sim card out of your iphone?

As long as you can get out the old one, then yes, but put in a new one.they-re usually free from the store. Try using a small plastic tool to get it out( plastic forks work well. I've used my girlfriends eyebrow pullers to get a broken one out before, but be careful and make sure the phone is off
