I'm currently subscribed to TPG's VM4 plan bundled with my internet, which gives me $550 worth of calls and 1.5GB of data for $16.99 per month. I rarely use the entire data package (only time I ever came close was when my home internet screwed up for a week or so!), have never breached the call cap and don't make international calls on the phone either, so it's fair to say I'm a very low-end user!
I've had a look at a few different providers though and it seems like there's a number of similar alternatives that offer the same deal for less (e.g. Bendigo Bank Telco or OVO), or more data for a similar or slightly higher price (e.g. Aldi).
Are there any especially good deals I should be checking out at the moment? Or should I just stick with TPG for the time being?
The Mobile Plans deal page which can usually be accessed by hovering mouse cursor over "Pages" on the top, shows you a list of mobile plan deals listed in order of + votes.
Try it out. I personally recommend Kogan though the catch is you have to buy 12 months worth in one go, but it's a big saving over other plans.
Their plans are:
SMALL PLAN $10.90 a month / 1.5GB ($132.59 upfront, Was $179.90)
MEDIUM PLAN $16.90 a month / 6GB ($205.58 upfront, Was $299.90)
