Receipt Unknown when the discounted offer expires.
The discounted $25 pack is a better value at the same price as the $10 starter pack. I believe the amaysim $25 starter pack is exclusive to Coles.
I noticed as well that amaysim has generally cheaper international call rates compared to the big 3 (as PAYG rate) to select countries. Handy for that use case scenario.
Is the starter pack 28 days or 30 days? Does it come with any data?
