Mguard Anti Theft

Hi,

Anybody can help me with this.

I installed the mguard in the Sony Ericsson mobile. Software loads correctly.. But there is an option in the Sony mobiles like Permissions and Autostart. In Permission SMS, I click the Don't Ask option. and in Autostart there are 3 options 1) Always Ask, 2)Ask once & 3) Never option. I have tried with all these 3 option... When I try to check whether this software works. I dont get any message on Sim change to the friends number... Anybody has tried this software.

Thanks
Chetz
