What Is a Restrict Calls Feature?
When you decide you want to use a parental control tool to monitor your kid's activities, you need an effective service that lets you protect your kid from outside threats. If you see that your kid receives a call from an unknown number, you can restrict it. It is also possible to easily block outgoing calls by clicking one button on your dashboard and ensuring no unknown people can reach your child.
uMobix is a software that allows you to not only monitor your kid's activities but is also an app to block calls and messages. This feature allows you to restrict phone calls on your kid's smartphone and control who can reach your kid and who is restricted.
You may use uMobix as an SMS and call blocker and a monitoring tool to track every activity on your kid's device. This feature ensures that a restricted phone number cannot reach your kid and potentially harm them. Combine all the available features to create a powerful tool for ensuring your child's digital safety.

How Does the Restrict Calls Feature Work?
The main advantage of uMobix is that it guarantees anonymity. Your kid will not find out that they are under parental supervision unless you directly say this. It operates on the target device in the background mode and does not leave an icon on the main screen, so the device owner cannot find the tracker by accident. All the updates are sent to you in real time, so your children are protected 24/7.
