You can order a replacement eSIM / Physical SIM by visiting your nearest Optus store or contacting us.

I ordered a replacement physical SIM card over the phone

1. To activate your replacement SIM card:
   • Give us a call; or
   • Visit your nearest Optus store with 100 points of ID
2. Insert your replacement SIM card into your device
3. To check whether your SIM card is active look for Optus next to the coverage bars at the top of your home / lock screen
   
   

It can take between 15mins and 4 hours for a SIM to activate. If it's still not active, try these steps:

1. Periodically turn your device off and on
2. Remove and re-insert the SIM card to make sure it's seated correctly
3. Sync your device with any companion software/cloud service it may have. See Device Guides for help
   
   

If you've ported your number across to Optus from another service provider outside of the below business hours, your old service will remain active with your existing provider until the next porting day:

• Monday to Friday, 8am - 8pm AEST
• Saturday, 10am - 6pm AEST (except national public holidays)
  
  
  

There's three types of physical SIM cards available. When you purchase a SIM card from Optus you'll receive a 3-in-1 SIM card containing all three types of SIM cards:

• Nano
• Micro
• Standard
  
  

eSIM is also available in some devices.

To determine which type of SIM card your device needs:

1. Open Device Guides
2. Search your device
3. Click the specs tab
   
   

Note: Ensure you select the correct SIM card for your device:

• Mobile phone SIMs are not interchangeable with Tablets/Mobile Broadband devices
• You cannot replace your Prepaid SIM with a postpaid SIM card (or vice versa)
  
  

You can find step-by-step instructions on how to insert your SIM card in our Device Guides.

1. Search your device
2. Click Getting started
3. Select Insert SIM
4. Follow the instructions
   
   

If you order a replacement SIM card you'll keep the same phone number.

If your contacts are only saved to your SIM card, unfortunately they'll be lost if your SIM card is lost or stolen.

If you have saved your contacts to your device, or backed them up elsewhere, you'll still have access to them when you replace your SIM card.

Once your SIM is activated, you might consider changing your SIM card PIN to help protect against unauthorised use.

eSIM is available for compatible mobile devices.
