I will travel to NZ and AUS from HK.
I want to know whether the Travel SIM card can be used in both NZ and AUS. If yes, I have following questions:
1. how much for NZ -> NZ calls ?
2. how much for AUS -> AUS calls ?
3. how much for NZ -> AUS calls ?
4. Whether the network data can be used in both NZ and AUS
5. Whether the top up can be only done in NZ ?
6. Whether the shop at ground floor of International terminals before or after securily after i arrive NZ from HK ?
Thanks a lot.
