My Galaxy Nexus is no longer connecting to Verizon's data network. I'm not finding any of the new phones all that interesting, so I've been thinking of getting a used Galaxy Nexus and moving the sim card from the old one to the new one. What exactly is the procedure to do this? Does Verizon need to be contacted? Is there something I need to do to the device other than taking the sim card out of the old phone and putting it in the new one?
