Where do I find SMS sent from AntiTheft on SIM change>

Hi, I lost a phone a couple of weeks ago, but had no luck tracking it, as it had obviously run out of battery.
Today, I have had several notifications from AntiTheft that say the SIM has been changed, and that someone has uninstalled AMS. It located the phone as planned.
I also had AntiTheft to ‘Send SMS to Portal’. I thought this would be useful, so that I could still send SMS commands, or have another way of tracking the phone through its new number.
Where in ‘the portal’ can I find that SMS? I just want to find the new number and bombard them with LOCK and SIREN commands.

Thanks to all!
