Mark as trusted

I have a phone that keeps showing me it has “untrusted sim”.
How can I mark it as trusted in the new interface?

Hi,

What I did was:

Go to Avast on your phone
Click on Anti-Theft option
Open Avast Anti-Theft
Enter your PIN
Your SIM will automatically be added to the trusted list

Hope it helps!

Thanks, Cleris.
What I need is an option to do that via the web interface, not the phone.
Do you know how?
