I use my Blackberry for international travel and travel within the U.S. and I need mg capacity to send messages, pics and documents. Depending on your carrier: call about 45 days before your trip and ask to add an international plans. When you get back, call and have it removed. You will be charged for one billing cycle. Calls are very expensive from Belize, but sending text messages and attachments are reasonable, depending upon your carrier and plan options.
