Off to Fiji in a couple of days and wondered if anyone has any info on the Mobile Broadband options in Fiji.

Sounds like Vodafone's 'flashnet' is the way to go but can you just buy a sim of the whole device?

Digicel has mobile bb at $15 for 450mb but again do you have to buy the device or can you buy a sim?

Is there anywhere to buy sims at the airport?

Any help is appreciated.
