Best way to block porn on smartphones

Step-by-step: https://techlockdown.com

Mobile device managers are used by businesses to completely control phones that are given to employees for work use.

You can personally use an MDM to restrict your own smartphones to enforce policies that make it difficult to access porn.

MDM's are future-proof method for blocking porn because businesses need to be able to control devices that are issued for company use. Smartphone companies like Apple, Google, and Samsung will always support mobile device management because they want companies to buy their phones.

Here's a quick summary of how you can use an MDM to purge porn from your technology.

Force the usage of apps
Use an MDM to install an app on your phone from your computer (through the MDM dashboard).

A distributed app cannot be uninstalled and you can also force device configuration.

Block apps
Completely restrict the usage of any application that can be downloaded from your phone's app store.

If you decide to block an app and it's already installed on the device, the MDM will delete the app automatically and disable the ability to reinstall it.

Enforce Device Settings
Almost any device setting can be configured from remotely from your computer.

You can restrict the ability to modify whatever setting you choose. For example, you could set up a DNS Filter vpn using the MDM, then restrict the ability to modify VPN settings on the device itself.
