Update your browser to stay safe online

If you're seeing this message, you may need to update your browser.

Without the most up-to-date version of your browser, you may be more vulnerable to cybersecurity threats, such as viruses and ransomware.

You also may have problems viewing our latest site features, as Telstra's website does not support outdated browsers. Find out more about staying safe online.

If you’re on a post-paid plan, use the table below to troubleshoot the most common problems and get your mobile broadband device online.

Lost/Forgotten Wi-Fi security password
  • You can find this on the main screen.
  • You can also remove the back panel of your device and check above the battery.
  • No internet signal
  • Can’t connect to mobile network
  • Limited internet speed
Check that:
  • You’re in a coverage area and there are no known outages
  • Make sure you’re close to the Wi-Fi, or connected to your PC if it’s a USB device
“A connection to the remote computer could not be established” error message (USB Devices Only)
  • Open the Telstra Connection Manager Software
  • Select ‘Internet’ from the list and click ‘Default’
  • Close and restart the Telstra Connection Manager Software
  • Now try to reconnect
“No USIM inserted” or “Limited Service” error message
  • Wi-Fi Devices: Press and hold the power button
  • USB Devices: Disconnect and reconnect to your computer
  • Make sure your SIM has been activated and installed correctly.

Good to know:

  • To connect, your device needs to be compatible with the Telstra Mobile Network. Look for the IMEI number - usually on the back of the device – then check its compatibility here.
  • If your device didn't self-install, you can install it manually by downloading a Getting Started Guide.
  • Telstra mobile broadband devices are locked to the Telstra Network, so non-Telstra SIMs won’t work in them unless they are unlocked.
