@lily-stockley try to reseat your sim card.  Power off the phone first,  then take the sim card out for a min before you put it back and power up again

if still fails, Best is to test your sim card on another phone if you have one around

@lily-stockley  - are you a current customer of public mobile, and have you activated these SIM cards?

If you have not activated them yet, you can do that here: https://publicmobile.ca/en/on/portal/activation

Also, note, you cannot use a previously used SIM that was once used for a previous account that is now closed.

Make sure that you have an active plan with your wireless carrier

You might need to remove your Sim card and put it back.
