I have an MCI prepaid phone card (from Costco) and can call Belize from home for 39 cents per minute, and from Belize to home for 50 cents per minute. This assumes you have access to a phone there in your hotel or condo, or a pay phone. Maybe not the cheapest, but it sure is simple! I've used it 3x in planning for our trip, calling Belize from home.
