FAQs about the Sydney eSIM
Will my eSIM work the moment I land in Sydney?
Install your Teraroma Australia eSIM at home before you fly. The plan starts when your phone first connects to a local network in Australia, as long as the eSIM line and data roaming are switched on.
Which networks does the Sydney eSIM use?
Our current Australia plans connect to Optus, Telstra. The network your phone picks depends on the plan and local signal.
Do I need a separate eSIM for other cities in Australia?
No. Australia plans are country-wide, so the same eSIM works in Sydney and anywhere else the local networks cover.
Can I keep my home number while using a Sydney eSIM?
Yes. Teraroma eSIMs are data-only and run alongside your home SIM, so calls and SMS to your usual number keep arriving.
What if I need more data while I'm in Sydney?
Top up your existing eSIM from the Teraroma top-up page. You don't need to install a new eSIM mid-trip.
