With Qustodio Premium, you can read the content of private messages (SMS text) received or sent on Android devices. Qustodio offers the option to know when text messages/SMS were sent or received and to whom, as well as the ability to read the messages exchanged. Please refer to this article to read more about SMS monitoring with Qustodio (Android only).
The Advanced Social Monitoring option can track posts on Facebook wall, but it is not possible to read the actual conversation. To activate Advanced Facebook Monitoring, please visit your Family Portal and go to Rules > Social Monitoring.
All other social networks or apps, such as Skype, Instagram, Snapchat, WhatsApp, etc. can be monitored with Qustodio as any other application. However, Qustodio will not reveal what was said or exchanged between users on these apps or networks, only when the app was used and for how long. It is possible to completely block these apps, or set a time limit for each in Rules > Games&Apps.
