To turn off VPN on an iPhone, follow these steps:
1. Open the Settings app on your iPhone.
2. Scroll down and tap on “VPN” (usually located near the top of the list).
3. On the VPN screen, you will see a toggle switch next to the VPN connection. Simply tap the toggle switch to turn off the VPN.
4. Once the toggle switch is turned off, the VPN connection will be disabled, and your iPhone will no longer use the VPN for internet access.
Note: The exact steps may vary slightly depending on the version of iOS you are using, but the general process should be similar.
