No Service on Telus SIM card

Hi,

I have tried all of the troubleshooting steps (including resetting network settings) and I still have no service on my iPhone. I have also tried other iPhones with this SIM card (does not work), and other SIM cards in my iPhone (does work).

It's been like this for a few months now and Telus phone support cannot help me.

Is it possible to check if your SIM card is active somewhere?

Thanks!
