My spouse was recently in Mexico, and I had to determine the cheapest way to call. AT&T has an international wireless plan called World Connect with a monthly fee of $3.99, and then my calls to a Mexican landline are $0.09 per minute. Without this plan, I would pay no monthly fee and $0.49 per minute.
