How to Remove Safari From Your iPhoneby Julius Vandersteen ; Updated September 28, 2017
When you get an iPhone, Apple’s cellphone with a multi-touch screen, you might intend to primarily use it for making phone calls, and not for browsing the Internet with the Safari browser that comes installed on every iPhone. The iPhone connects to the Internet via Wi-Fi and cellular data networks, enabling you to surf the net, exchange email, access Apple’s iTunes Store to download music and videos, and use FaceTime to make free video calls. You can easily remove the Safari app icon from the home screen of your iPhone if you don't want it.
Press the “Home” button to go to the iPhone’s home screen.
Tap the “Settings” icon on the home screen.
Tap “General," then tap “Restrictions.”
Tap “Enable Restrictions.”
Type a four-digit passcode, using any digits that you want, and then type it once more to confirm. Write down your passcode and keep it in a safe place if you think you might forget it. The “Restrictions” settings page appears.
Tap the “Safari” option to “Off.” This disables Safari on the iPhone, and the Safari app icon is removed from the home screen.
Press the “Home” button to return to the iPhone’s home screen. Only the person who knows the “Restrictions” passcode can enable Safari again.
