You can save quite a bit of money over a year with these, so they are worth checking out if your monthly plan has been creeping up in price. The cheapest I have seen so far are OnePass Mobile’s (previously Catch Connect) 200 GB plan for $149, Kogan Mobile’s 140 GB plan for $150 and Lyca Mobile’s 200 GB plan for $150. Kogan also has a 300 GB plan on a big discount for $159. So around $12.40 - $13.25 a month, which is way less than even the cheapest monthly plans.

As always, providers can use different networks and have different terms and conditions and benefits (Lyca Mobile also includes free international calls to 39 countries, for example) so it’s worth reading the critical information summaries carefully before you buy. International SMS is something commonly not included with these plans, so you may need to pay extra for that.
