SIM Change Alert

Every time the TARGET phone changes SIM cards you will instantly receive an SMS alert on your own phone telling you that the SIM card has been changed.

This means you do not need to worry about whether or not FlexiSPY will stop working as soon as the TARGET phone changes SIM card. FlexiSPY makes it easy and convenient to monitor others and SIM change alerts are only one part of a wide range of great FlexiSPY features.
