Can I put old iphone sim card in unlocked iphone?

So, my iphone 4s took it's last swim this weekend. Can I take my sim card (hoping it still works) and put it in an unlocked iphone 4s? Will this work?

Yes The Sim Won't Be Affected But you Have To Dry the sim Before You Put It On The New One

Yea… That's the benefit of an unlocked phone.

Yes you can.
