Any type of spying is very much illegal. Moreover, getting access to someone’s text messages over Wi-Fi is also technically impossible. Unlike the widely advertised Wi-Fi spy software, mSpy is a legal parental control app that parents can install on their child’s device to make sure they’re staying safe online and using their phone responsibly. mSpy only lets you see the list of Wi-Fi networks the kid connects to and block the ones parents see as not safe.
