This Method is by Using Third-Party Store called TutuApp
First we start to go to the site https://tutuapp-vip.com
Click on Install and choose either of the config profiles (try the other if one doesn’t work). You’ll be prompted with a dialog box saying, “This website is trying to download a new configuration profile.” Click on Allow.
You’ll soon be notified that the profile has been downloaded. Close it and navigate to the iOS Settings app.
Here, click the Profile Downloaded option given on top. If not available, tap General and head to the Profiles and Device Management section.
Select TutuApp and click on the blue Install button. Enter your phone’s passcode if prompted. Hit Install again, and you’re good to go.
