What if I’m using an existing device?

If you're using your own device, you should first check;

  • Which size SIM card you’ll need. If you're not sure check the manufacturer's website or guide or visit your local Telstra store
  • That your device is unlocked and compatible with the Telstra mobile network. Some devices are locked to other providers. You will need to contact your provider to have your phone unlocked. You may be charged an unlocking fee for this
  • That your mobile supports Telstra’s network. Check the manufacturer's website or our online device guides.
  • That you have the correct data settings. These let you browse the internet, send emails or MMS. Many mobiles will have their settings updated automatically over the Telstra network. To find out if your settings are updated automatically, visit Mobile Support or check the manufacturer’s website.
