Hello all, I will be traveling to AU over the christmas for 2 weeks and I'm looking to use my iPhone 5 (Will unlock it) in Austrailia. I'm looking for the best Pre-paid carrier. I won't be using call/txt, but mainly data. (Around 1GB or more). What's my best carrier option? Right now I'm looking at the $50 Vodafone plan..Also, does anyone know what flexible credit means? That $1,000 number scares me a little. Sorry, Noob here, first time. Thanks for any help! Much appreciated.
