If you’re looking for more data every month and you’re willing to change your mobile provider you can get a pretty great sim-only deal with Optus at the moment.
Their $50 My Plan Plus is available for new subscribers only on a 12 month contract. The plan offers all the usual features including unlimited SMS and MMS to national and international numbers. You can also get unlimited national calls and up to 500 minutes for standard international calls – and of course the icing on the cake 15GB of data.
Of course as a SIM only you’ll need to bring your own handset, so you’ll need one that supports Optus LTE bands. Optus uses the Band 3 (1800MHz) and Band 28 (700MHz) network as well as the TDD Band 40 (2300MHz) Optus 4G Plus network around Australia. You’ll probably need to check out the Optus mobile coverage map to see if your area is supported.
As a bonus, if you’re looking to stream the English Premier League you can get access to the streams if you subscribe before August 22nd.
You can check out the plan in the PDF available on the Optus website – so point Optus that way if you’re interested
