How to Reset Network Settings on iPhone
Take the following steps to reset the network settings on your iPhone: Your iPhone resets its network settings and then restarts, which takes a minute or so. When you can use your phone again, enter your passcode. Your phone should automatically reconnect to your cellular provider. If your iPhone doesn’t auto-connect to your mobile network, contact your carrier or Apple for support. You also need to rejoin Wi-Fi networks. Tap Settings > Wi-Fi and then tap the name of the network you want to join. If prompted, enter the network password and then tap Join.
What Happens When You Reset Network Settings
When you reset the network settings, the configurations for Wi-Fi and cellular networks return to the default settings. A reset also clears virtual private network (VPN) configurations. After a reset, your iPhone reconnects to your carrier, and you’ll need to reconfigure the Wi-Fi and VPN settings manually. Before you reset your network settings, you can try the following tips when you experience a network connection problem with your iPhone. They are quicker than going through resetting your network, and they often solve the problem.
Tip: Toggle Airplane Mode
Put your phone in Airplane Mode for a minute or so.
Tip: Power Off and Power On
If toggling Airplane Mode doesn’t work, turn your iPhone off and back on.
Tip: Forget and Reconnect to Your Wi-Fi Network
