I will be in NZ Wanaka for 10 days and need mobile plan/sim for the trip.
Wife is Optus, last year trip she had to pay an extra $100 because of spam calls even when we do not pickup. Not sure did she get the daily international pass, I forgot
Any recommendation on what we mobile plan/sim we should get?
$10 Optus Prepaid Sim & $20 Roaming Pack - equivalent to 10GB
Alternatively, check over eSIMDB if you have an eSIM Compatible phone.
Just disable Roaming on your Telstra/Optus SIM/account dashboard and have WiFi Calling enabled.
