How do I return my mobile?

  1. Book an appointment online to visit your nearest Telstra Store.
  3. One of our store Tech Experts will take a look and help you with some further troubleshooting to see if they can solve the problem on the spot.
  5. If the problem is determined to be the result of a user error instead of a software, hardware or a network fault, then a fee may apply. You will be contacted by Telstra Device Care if a fee applies, before they proceed with the repair or replacement of your device. In the event that you cannot be contacted, the device will be returned to you unrepaired.
  7. If we can’t fix it on the spot and your device is in warranty, we’ll request an express device replacement from Telstra Device Care. Your replacement will normally arrive at your local Telstra Store in one to two business days.
