Both Cashrewards and ShopBack are offering $10 cashback on Amaysim's $15 65GB mobile plan for the first 28 day renewal. It is listed as a 50GB plan under ShopBack because the base plan is 50GB.
Remember to turn off auto renewal at their account portal.
Billing period is 28 days, not the full calendar month (so 13 renewals per year vs 12 if you choose to stick with them).
Is prepaid and they allow you to continue receiving calls and texts for 12 months after expiry, which is longer than any other telco offering prepaid plans AFAIK.
Uses the Optus network (and now owned by Optus, if you've been following the news).
Both Cashrewards and ShopBack only allow one purchase per month per account (so 2 per month if you have accounts with both of them).
Trying to get my head around the maths here.
So is that $15 for three months altogether, therefore $5 a month for 21.6GB data?
