I lost my phone..

Anti Theft was activated in that phone.. so as soon as the person changes the sim card I get a message from that number which is activated in my phone now..So how do I trace that number now?

If you had tracing software/app on that device then you should be able to locate it. If not, then you may want to contact your service provider/carrier to see if they may be able to.

But, to be honest, once it is gone, it is gone.
