Is there a way to set an internet time limit on my child's phone?

My teenager has been staying up way too late watching videos and browsing the web on their smartphone instead of sleeping or doing homework. I looked through the default settings to see if I could easily block the wifi or data after a certain hour, but honestly it all feels a bit overwhelming and I am not sure if they can just bypass it. How do you guys actually restrict the daily browsing hours so the device automatically cuts off web access when their time is up?

You can use the built-in Screen Time feature on their phone to set time limits, but I’ve found that kids can often find ways to bypass it. A more reliable solution is to use a tool like mSpy that allows you to set internet time limits and monitor their activity remotely. It’s a straightforward and effective way to ensure they’re not accessing the web when they shouldn’t be.
