- Open the Settings app
on your device. - In the Settings menu click on Security & location > Credential storage / Advanced > Encryption and login information > Install from storage/Install from sd card (please note! The exact settings name varies from device to device, so you can use the search box)
- Go to the folder where the downloaded certificate is located from Step 1 > Click on the downloaded file (default certificate name is netfree-ca.crt).
- In the panel that opens, give a name to confirm (any possible name) and choose the option VPN and apps
- Click on "OK".
