Hello,
unfortunately you can’t pair your phone with your my.avast.com account without the phone at hand.
But I don’t see why you couldn’t use SMS commands. If you didn’t set Anti-Theft only to accept SMS commands from the friends number, you can send it from any phone.
Of course you might not get a reply if the phone is turned off or the SIM card has been changed. Since the Friend can’t receive SIM card change notifications, this might be the case.
regards,
Werner
