Important Notice: Limited Optus Mobile Coverage in Remote Areas (ZTE Devices)

Summary

Some mobile phones and devices manufactured by ZTE may not work in a small number of very remote Australian locations where Optus uses Satellite Small Cell (SSC) technology.

If you use one of these affected devices and travel into these areas, you may be unable to:

  • Make or receive calls
  • Send or receive text messages
  • Call Emergency Services (000 or 112)

For most customers, this will not affect everyday use, as the impacted locations are limited to specific remote outback sites.

What is causing this issue?

Optus has identified a technical compatibility issue between:

  • Certain ZTE mobile devices, and
  • A small number of Satellite Small Cell (SSC) sites used to provide coverage in very remote parts of Australia.

When an affected ZTE device is within range of one of these SSC sites, it may be unable to connect to the Optus mobile network.

Where does this occur?

The issue only affects specific remote locations across parts of:

  • South Australia
  • Queensland
  • Western Australia
  • Tasmania
  • Northern Territory

These sites typically cover roadhouses, national parks, and remote communities, with an approximate coverage radius of 0.5–3 km per site.

Optus maintains an official list of affected locations, which is updated as sites are upgraded.

Do I need to take action?

If you do not travel to very remote or outback areas:
No action is required. Your service will continue to work as normal.

If you plan to travel to remote areas:
We strongly recommend checking the Optus SSC location list before travelling. If your plans include any of the listed areas, please contact our support team so we can discuss alternative options to help keep you connected and safe.

 

Why is this important?

In affected areas, impacted devices may be unable to call Emergency Services using the Optus mobile network. Before travelling to these locations, you should check if your device is listed as impacted on the Optus SSC location list at the link provided above.
