Hi, My family and I are visiting Perth for 8 days, arriving 24 Nov 19. We live on Guam (US territory) and our iPhones are unlocked for international use. However, my carrier says our phones will only work on a GSM network. So, a few questions:
1. Is that (GSM) compatible with your network in Perth?
2. Should I buy a SIM card now and have it sent to me on Guam, or should I just buy one at the airport in Perth and activate it there?
3. I want the $30 plan for 35GB of data. Do you get that much data initially or only when you recharge?
You'll be able to use your iPhones over here.
You can't purchase a SIM until you arrive, the airport has an Optus shop.
It sounds like you want this plan:
35GB standard data on first three Optus Prepaid Epic Data recharges
Enjoy your stay down under!
