International Options

I will be relocating to Europe next week. I have two Verizon Blackberry 9630s. One is currently connected through Verizon and one is inactive. I would like to use my Blackberry overseas, along with BBM.
I am looking for advise on how to use a SIM card in either of these phones and how to un-link them from the Verizon network- if that is the best option for a person in my situation.

Thanks in advance.

if you want data text and voice it will cost you much. Its 64 a month for data a month from what I've asked them if you go international with it. You have an option to also unlock the phone and use the sim card from a different carrier
