I would like recommend 3 importants issues that I think willbe good to add on the Mobile Security Software:
1.- Able to send message by SMS and show it on the main screen with the locked screen.. Message like: If you found this phone, please call to XXXXXXXx.
2.- Not able to unlock (even with the password) if the SIM was changed and it haven´t credit to send a sms or not signal lock of if the cell phone is power on without a SIM insatlled. the idea is be sure that the phone can send the SMS if the SIM was change of if someone try to use the phone without SIM or Signal.
3.- Able to take and send a pic to an email account, activating the WiFi (in invisible mode), find a WiFi open network and sending the email.
