To piggyback on mmastera's post, I too am going to Cancun. I am somewhere between Mexitel, Movistar, and Telcel. However here is my problem. I really don't want to rent a phone if I have my own, but I can't read the Movistar or Telcel websites because I don't read spanish and google doesn't translate the webpages. Therefore I don't understand the who, what, when, and how as it relates to rates, sim card purchases, and top offs. But I will do the Mexitel thing if their rates are the best and reputation is good. Please help me with a solution.
