It depends on your current situation, but here's a handy guide to help you out.
When to pop in your new SIM:
If you’re going to be using a new number, then insert your SIM after you’ve completed the online activation process. This ensures your number is ready to use.
If you're replacing a lost or damaged SIM, you can insert the new SIM right away, but remember to activate it through your online account first.
If you're switching from another network and keeping your number, wait until you receive confirmation that your number has been transferred before inserting the new SIM. This usually happens on your agreed switch date.
🔔 Remember, regardless of when you insert the SIM, you'll need to activate it through your online account to get it up and running.
