I had just bought an Oppo A52 and was looking for a prepaid plan and came across these offerings from Optus.
This covers several plan types including but not limited to;
* Optus Prepaid Epic Data,
* Optus Prepaid Epic Value,
* My Prepaid Daily Plus,
* Optus Prepaid Long Expiry.
All of the above plans are listed as
$30 markdown to $5.
