Verizon SIM card?

Hello,

I recently upgraded my Verizon iPhone 4S to the iPhone 5. I sold and shipped my 4S on ebay. After doing so, I realized that I forgot to check/remove the SIM card. My question is, does the Verizon iPhone 4S have a SIM and if so, does it contain any sensitive information stored on it?

On a side note, I restored the phone as well as doing a wipe via an app.

Would appreciate any help.

Thanks,
