Forgive the noob question. I have a trip planned to Cape Town and I was wondering if there was a way to use my Verizon iphone there without having to switch to an international plan. I remember reading somewhere that I could buy a prepaid SIM card and just pop it in when I got there. Is that true? Can I buy the SIM card online now so I have it ready to go? Are there any stores on Los Angeles that I might be able to buy from? Thanks in advance for any replies.
