Can I use a Verizon iPad mini with Wi-Fi only?

A friend just gave me his Verizon LTW iPad mini. I don’t have Verizon.

Do I need to remove the SIM card to use it on Wi-Fi only? What problems will I encounter not having Verizon and trying to use this device? What settings do I need to turn off to disable Verizon’s service on this device? How does this SIM card get removed?
