How to Reset Network Settings on iPhone 18 Pro

Internet is important for many of the things you use your iPhone 18 Pro and iPhone 18 Pro Max for: checking email, social media, browsing and more. If you are having connection issues with your iPhone, you may need to reset your Network Settings. This is not usually the first step you would take to try to resolve issues, as it can mean you will need to re-enter some settings and passwords, but when other troubleshooting steps fail, resetting your Network Settings can fix the problem.

Here are some of the issues where you may want to try resetting your Network Settings:

Cellular data not working
Slow Wi-Fi connection
iPhone 18 Pro can’t connect to Wi-Fi
Cellular data for apps keeps turning off
Wi-Fi password sharing not working

Resetting your Network Settings will reset your Wi-Fi networks and passwords, your cellular settings, and VPN and APN settings. Apple also notes that your iPhone’s name in Settings > General > About is reset to “iPhone”, manually trusted certificates (such as for websites) are changed to untrusted, and cellular data roaming may be turned off. Your other data will not be deleted.

Things you can Try First

Briefly, here are some things you can try before resetting your Network Settings when you are having connection issues.

Update your device: Go to Settings > General > Software Update and install any available updates.
Airplane Mode: Go to Settings. Tap the toggle switch next to Airplane Mode, wait 20 seconds, then tap to turn it off again.
Restart your iPhone:
- Press and hold either volume button and the side button until the power-off slider appears.
- Drag the slider, then wait 30 seconds for your device to turn off.
- To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.
For Wi-Fi issues:
- Unplug, then re-plug your modem/router.
- Forget the Wi-Fi network: Go to Settings > Wi-Fi, then tap the More Info button next to your Wi-Fi network. Tap on Forget This Network. Tap Forget to confirm.

Reset Network Settings

Reset the Network Settings on your iPhone 18 Pro. Resetting your network settings causes all network settings to be removed, including your home, work, and school network configurations. Reset network settings only if other solutions fail. If a school or business configures your network, consult with IT or the network administrator before you reset the network. Apple notes that VPN and network settings installed by a configuration profile or by device management are not removed by this reset — those have to be removed from Settings > General > VPN & Device Management instead.
