Avast anti-Thef

Hi, I just have a question about the application Avast anti-Thef.
If my cellphone is lost and the thief extracted the SIM card, I can’t locate it?
It doesn’t really happen, is just a question :smiley:

It’s a question that you need to ask in the mobile section of the forum http://forum.avast.com/index.php?board=37.0
