I am going to London soon for a little less than a week. What happens if I turn on my Verizon Nexus?? Will I get big charges from Verizon for international usage, or will nothing happen? Can I use the Wifi portion of the phone to Skype back to the US? If so, are there open Wifi spots in London? If this won't work I guess I will buy a burn phone when I get there for minimal usage. Thanks in advance for the advice.
