Posting this because it can be used on the 365 Day "Pay As You Go" $10 Plan which was very popular.
Proof here. Credit to DaBz.
The PAYG plan is handy if you want to park your number or need a phone for mainly receiving calls with data turned off.
Also I think Amaysim works overseas for receiving SMS (please comment if you know for sure).
Pay As You Go Plan Features

- 12c / standard SMS
- 5c / MB data (no data included, it's a PAYG plan)
- 29c/min calls to 13 numbers, free calls to 18 numbers in Australia
- 12c/min voicemail retrieval
- Optus 4G Network with VoLTE
- No lock-in contract

Good deal (if you want to be with optus/ 100% optus subsidiary )
Credit lasts for 365 days
Dont forget incoming/OTP receiving lasts a lot more than 365 days (maybe another 60/90/180 days) after the 365 days
Edit:- after finding out optus owns 100% of amaysim I personally would avoid it (due to personal hate towards optus)
