Disabling a VPN on an iPhone might not be straightforward due to security considerations.

1. Browser Extensions: Look for browser extensions or add-ons that block blocked websites. Examples include AdBlock Plus, Blocku, or Safe Browsing.

3. Device Settings: Check the device's settings for any browser extensions that block ads or blocked websites.

4. Privacy Settings: Ensure that your device's privacy settings are set appropriately to prioritize privacy over blocking ads.

5. Check for Suspicious Weaves: Be cautious of websites that appear to be blocked but are actually your own. Only click on links that seem legitimate.

Remember to always be cautious of suspicious websites and avoid clicking on unknown links. Prioritize privacy and security over blocking ads.
