How do I turn off a security web proxy on my iPhone? or Can someone help me turn off a security web p

If you’re trying to turn off a security web proxy on your iphone and it’s greyed out, it’s probably a configuration profile.

Try this:
- Settings > General > Profiles (or VPN & Device Management).
- Tap any profile and hit Remove.

No profiles? Might be a network-level thing. Try a different Wi-Fi or cellular.
