Get a 5GB SIM-only mobile plan for just $10 per month (with no catches)

Optus provider Circles.Life has refreshed its range of SIM-only mobile plans and there's a clear standout if you're looking to save money on your monthly bill. The telco has a new entry-level plan that gets you 5GB for just $10 per month. While that's not a huge allowance, it could be a great pick if you're a light user or you're looking for a plan for a child.

The plan is contract-free, and if you go over your allowance, you'll pay $10 for a 3GB top-up.

For comparison, the majority of plans around the $10 mark only have a gig or two of data, which makes their use case a lot more limited. iiNet and Internode are two key exceptions where you'll get 8GB for $10, but only for your first six months after which you'll pay $19.99. Moose Mobile has a similar offer where you'll get 6GB for $9.80 per month for your first year, but you'll pay $15.80 per month thereafter.
