Does My SIM-Only Plan Have Access to Optus 5G?

With the growing availability of Optus 5G across Australia, many customers are asking whether their current SIM-only plan supports 5G or is limited to 4G.

Here’s everything you need to know:

Q: How do I know if my plan includes access to Optus 5G?

Your plan’s network access depends on the specific plan you signed up for.

• Some SIM-only plans include 5G access, while others are limited to 4G.
• You can check your plan details by logging into My Account or contacting our Sales Team at 13 22 10 for confirmation.

Q: Will I need a 5G-capable phone to use Optus 5G?

Yes. Even if your plan includes 5G, you will only be able to use it with a 5G-compatible device.

• If your phone only supports 4G, you’ll remain on the 4G network regardless of your plan.

Q: How can I check if my area has Optus 5G coverage?

To enjoy 5G speeds, both your plan and device must support it and 5G must be available in your location.

• Visit the official Optus Coverage Map
• Enter your suburb or postcode to confirm whether 5G is available in your area.

Q: My device supports 5G, but I’m not seeing 5G coverage. What should I check?

Here are a few steps to troubleshoot:

• Ensure network mode is set to Auto or 5G preferred. Some devices allow manual network selection.
• Check your location: You may have moved out of a 5G zone.
• Restart your phone or toggle airplane mode on and off to reconnect.
