Activate your service
What type of service would you like to activate?
Activate a new Pre-Paid physical SIM card
If you're looking to move your mobile service to Telstra from another provider, you'll need to be able to receive calls and texts on your current service. If you are currently unable to receive calls and texts, activate a new eSIM service and you could be back online in as little as 10 minutes with the My Telstra app.
To activate a replacement SIM
To activate a physical replacement SIM for an existing Pre-Paid service:
New Post-paid physical SIM activation
Insert your new SIM into your device. If the SIM is for a new service, it will automatically activate once you accept delivery.

To activate your SIM later
If you don’t want to activate your SIM now, you can do so later or, wait until your service is automatically activated seven days after your delivery is confirmed. If you choose to wait for the automatic activation, continue using your current SIM until your Telstra SIM is active.
