I use Cellcard which is fine for in towns. People traveling into the countryside probably use another carrier. You can find
data pricing here. It looks like iNET200 would be what you're looking for.
If there's a cellcard kiosk at the airport grab one there. Otherwise in town there will most certainly be a large HQ.
