Anybody else not getting public mobile service on their phone right now?
Check for Telus outages in your area. Also try rebooting your phone.
Make sure you are not a victim of sim jacking:
If you tried a network reset, please check there isn't a network outage in area.
Is your account displaying as "active" under self serve? Does it need to be topped off?
In your self service account, choose Change Sim Card.
Ensure the last 4 digits on the self-serve SIM number match your SIM card to ensure you have not been sim jacked.
If they do not match, while still on the self-serve account, put your phone in lost/stolen mode and change the password. Then check and secure all your financials.
