While I am happy that my GS4 is a "World phone" and therefore capable of picking up a GSM signal in other parts of the world, I am not so happy with what VZW charges me for data usage to do so. I've heard a bit about picking up a local SIM card and thereby paying local rates. What I'd like to know is: is it really that simple? Also, will VZW have kittens and not let me reactivate my VZW SIM card when I come back? If anyone who has done this can just walk me through the steps involved, I'd really appreciate it.
