Free 23GB for 30 days with Kogan Mobile

If you've been thinking about switching to Kogan Mobile, now's the time. The prepaid phone service is offering a free 23GB of data for 30 days. But only if you get a new Kogan SIM before March 31.

What? Why? How?

The promo is for new customers bringing their mobile number from another network (except Vodafone, sorry). The deal includes a free SIM card and unlimited national talk and text. This offer is actually one month of free access to Kogan's XL prepaid plan, which is usually valued at $49.90.

If you like prepaid with lots of data, you're unlikely to regret the switch. Kogan Mobile offer some of the cheapest prepaid, large data allowance plans around. And if you're unsure about whether Vodafone network coverage is right for you, this is a great opportunity to spend 30 days trying it out, commitment- and cost-free.

Here's how much you can expect to pay for your Kogan mobile service, once the offer expires:
