If you have been with VZW for a while try to get them to unlock it for free. Tell them that you're going to be doing some traveling outside of VZW coverage area. It might not work but the worst that can happen is that they say no. Then pay to unlock it. If you have to pay then check out Horizon Wireless
. They did my 8100 and 8320.. they will probably end up doing my 9530 as well.
