I'm traveling from the United States to Cancun Mexico for a week in February and am a little confused as to what to do about my data plan. AT&T explained their $3.99 package for World Connect so I can make calls at a discounted rate (9cents/minute), but didn't adequately explain what I need to do about my data plan. The hotel has wifi so I won't be using my data plan and don't want to pay for random things like incoming e-mails, etc. Is there a way to turn the data plan off on the phone or does AT&T do it? I just don't want to come back to all these crazy charges!
