The most notable new postpaid option is the $49 SIM only plan, available on a 12 month contract. That includes unlimited national calls and text, as well as 2GB of data and free calls to other 3 and Vodafone network customers. The site doesn't make it entirely clear that it's an all-you-can-eat cap, but in fact it is, and a potentially good deal if your local Vodafone coverage is OK.
For new prepaid customers, Crazy John's is charging 10 cents per minute for mobile calls with a 10 cent flagall, while text messages cost 1 cent each and data is 3 cents per megabyte. That makes it arguably cheaper for data and calls than the recently launched plans from Amaysim, though there's no direct equivalent to Amaysim's 1GB for a month for $9.95 deal.
