Switching Carriers on a Verizon iPhone 4S?

I have an iPhone 4S, that is under Verizon. My bill has gone off the roof & they already disconnected my service on Verizon. I would like to switch to another carrier (SIM CARD), is it possible for me to switch to any other carriers such as T-mobile or Simple Mobile or H2O?

Yes bring it to the Carrier

No,

The SIM card slot in the American 4S won't work with American carriers. It's there so you can use the phone outside the US. You will not be able to use that phone with any other carrier.
