4g to come early 2016 according to whirlpool http://whirlpool.net.au/wiki/kogan_mobile. You can also get quantas points.
Kogan currently are giving an extra 1gb or 2gb depending on plan if signing up to 12 months. They use the Vodafone network (3g)
Unlimited sms/mms and calls. I am not sure if international sms/call are allowed, but none is included in the plans I will add info as soon as I find out.
This is possibly the cheapest 7gb plan for 12 months without switching around.
Ew, Kogan.
