Woodford2, I am sure Mexico will be awesome. I know who vital it is for you to be able to use your phone without worry. I want to make sure I provide you with the most accurate information. The Go Unlimited does include Mexico. Please keep in mind that you only get 500 MB of high speed data per day while you are there. Your speeds will be reduced if you use anything after that. Keep in mind you can always connect to Wi-Fi. Does this help?
