I have a US iPhone 3g with AT&T but plan to unlock it prior to my trip to Central America (Guatemala, Honduras, Belize and Nicaragua). I'll mainly be using it for data (e-mail, web, twitter) and SMS, but also a little voice within the region and receiving calls from the states.
What's my best option for coverage (voice and data)? What is the best pre-paid SIM card to work on all those countries? Or will I have to buy one SIM for each country? Will the iPhone 3g work on those frequencies or would I need to buy a different phone?
