Vaya has announced 4G plans starting at $9 per month for phones and data-only plans for tablets from $33 per month.
[CORRECTION: this article originally incorrectly stated that Vaya's plans are pre-paid plans. The plans are post-paid. The article has been corrected.]
If you want a cheap phone plan you no longer have to go with a plan from the big names like Telstra or Optus - alternatives include phone SIMs you can buy from Woolworths, Aldi and Kogan.
Your phone calls and data will still travel over the networks of the likes of Telstra and Optus, but the prices and conditions are different.
One of the shortcomings of most of these SIMs is that they only provide 3G service. So if you have a 4G phone or tablet, you won't get the higher speeds available from a 4G network.
Among the first that we are aware of to offer 4G service is Vaya.
uses the Optus 4G and 3G network, and offers plans starting at $9 per month for phones and data-only plans for tablets from $33 per month for 10GB of data.
Depending on your habits, these plans may be a better buy that Optus's prepaid plans. Very light users may be able to get by on the $9 Vaya plan, which only comes with a measly 100MB of data per month. The cheapest SIM-only plan from Optus is $20 per month for 200MB. The cost per SMS and standard two-minute call is the same (25c and $2.15) in both cases.
For many people, 100MB is hardly going to be enough. The next most expensive Vaya plan costs $16 per month for 500MB. The full list of Vaya mobile plans is here
And at the high end, Vaya offers unlimited voice calls and texts for $45 a month, but with Optus that's only a feature of the $60 plan, which is only available on a 12 month contract. Vaya also provides 3GB of data per month compared with 2GB from Optus.
