What Do You Need Before Activating Your Telstra Prepaid SIM?
Before you start, make sure you’ve got everything ready. There’s nothing worse than getting halfway through activation only to realize you’re missing a crucial detail.
You’ll need:
- Your Telstra prepaid SIM pack (unused).
- A phone that’s unlocked (or locked to Telstra).
- A stable internet connection (Wi-Fi or mobile data).
- Your personal details (name, address, ID if required).
Why does this matter? If your phone is locked to another carrier, the SIM won’t work. And without internet, you can’t complete activation. Pro tip: Keep the SIM pack handy—you’ll need the 19-digit SIM number from the back.
