I’ll be straight with you – Telstra makes the prepaid activation process super straightforward. Just follow these steps:
- Open any web browser and go to telstra.com/activate
- Scroll down and click Activate my Pre-Paid Service
- Enter your 13-digit SIM serial number
- Click Check Serial Number
- Choose if you want a new number or to transfer your existing number
- Select if this is for a mobile phone or data-only device
- Enter your ID information when prompted

You’ll get a confirmation text or email when it’s done.
Pro Tip: It can take up to 4 hours for service to fully activate, so be patient!
Transferring Your Number?
If you’re bringing your number over from another provider, it can take up to 48 hours for the number port to finish. In the meantime, you may be assigned a temporary number. Once the port completes, your old number will replace the temp one automatically. Easy!

Post-paid setup only takes a few quick steps:
- Head to telstra.com/activate

And that’s seriously all there is to it! You’ll be up and running on Telstra’s fast, reliable network in no time.
