I've had a few friends switch from Skinny to kogan mobile lately. They all say better pricing on Kogan mobile using the yearly option and better coverage on the vodafone network plus free MMS and voicemail.
That's one thing that annoys me about the main telcos, why are they still charging for MMS and if so why is it as much as 50c/image? As I understand it MMS goes through a variation of their data network but from a user's perspective it goes through their mobile data which most people already pay for. There are many who don't have everyone connected via the multitude of IM apps which do it for free. At least 2Degrees have abandoned voicemail access fees.
@Groucho You have a MMSC that sits off the Core packet network to handle MMS / PXT messages and also SMS is required (end user does not see these SMS)
The licence fees to have the MMSC is not cheap and then you also have power and the support staff to pay for!
I looked after the Vodafone MMSC for quite a few years and it's not cheap to run!
