How to Reset Network Settings on iPhone: A Complete 2026 Guide

Your iPhone connects to Wi-Fi at home but shows “No Internet,” or your cellular data works for messages but not for browsing, and nothing you try makes it behave. Before you book a repair appointment or factory reset the whole phone, there is a middle option most people never find. Learning how to reset network settings on iPhone can fix stubborn connection problems in under a minute.

Resetting network settings erases your saved Wi-Fi networks and passwords, cellular settings, VPN configurations, and APN settings, then restores Apple’s factory network defaults. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings, enter your passcode, and confirm. Your photos, apps, messages, and contacts are not touched.

This guide explains how to reset network settings on iPhone safely: exactly what the reset does and does not erase, how to save your Wi-Fi passwords first so you are not locked out afterward, the step-by-step process for every iOS version, what to do after the reset, and how to decide whether you even need it.

Key Takeaways

• Reset Network Settings wipes all connection preferences (Wi-Fi networks and passwords, cellular and APN settings, manually added VPNs) and restores Apple’s network defaults, while your photos, apps, and messages stay untouched.
• It cannot be undone, so recover and write down your Wi-Fi passwords first using the steps in this guide.
• The path on iOS 15 and later is Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings; iOS 14 and earlier use Settings > General > Reset > Reset Network Settings.
• After the reset, rejoin your Wi-Fi, check for a carrier settings update, re-enter any custom APN settings, and re-add manually configured VPNs.
• It fixes problems caused by corrupt settings on your iPhone, not problems with your router, ISP, or carrier network.
• A managed work or school iPhone may block the reset; ask your IT admin before trying.

What Does Resetting Network Settings Do on an iPhone?

Resetting network settings wipes every connection preference your iPhone has learned and restores Apple’s factory network defaults, without touching your personal data. Apple’s iPhone User Guide defines it as resetting “all Wi-Fi networks and passwords, cellular settings, and VPN and APN settings.”

An APN, or Access Point Name, is the gateway setting your iPhone uses to reach your carrier’s mobile data network. If your carrier gave you custom APN details, the reset erases them and you will need to re-enter them afterward.

What gets erased

Setting	What happens
Saved Wi-Fi networks and passwords	All removed, including custom DNS and proxy settings for those networks
Cellular settings	Reset to defaults, including carrier APN settings
VPN configurations you added manually	Removed. VPNs installed by a work or school profile usually survive. Our VPN definition guide explains how VPN tunnels work if you need a refresher.
Manually trusted certificates	Revert to untrusted
Device name	Returns to “iPhone”
Cellular data roaming	May switch off; check it if you travel

What is kept

Your photos, videos, music, apps, messages, contacts, calendars, documents, iCloud settings, and SIM or eSIM data are all kept.

What about Bluetooth?

Here is a genuinely disputed point. Apple’s official list does not include Bluetooth pairings, yet several troubleshooting guides claim Bluetooth devices are forgotten too. The safest approach: assume you may need to re-pair Bluetooth accessories (headphones, car systems, smartwatches) after the reset, and you will be pleasantly surprised if you do not.

Before You Reset: How to Save Your Wi-Fi Passwords First

The most common regret after a network reset is losing Wi-Fi passwords nobody wrote down. The reset cannot be undone, so treat this as mandatory preparation.

How to find your saved Wi-Fi passwords on iPhone

On iOS 16 and later: open Settings, tap Wi-Fi, tap the network name you are connected to, then tap the Password field. Authenticate with Face ID, Touch ID, or your passcode, and the password appears. Write it down or copy it somewhere safe, then repeat for each network you use regularly.

On iOS 18 and later: open the Passwords app, go to the Wi-Fi section, and you will see every network your iPhone has ever saved, each with its password visible after authentication. This is the fastest way to collect all of them at once.

Also plan for passwords you do not control, like an office network: arrange to get them again before you reset.

A quick pre-reset checklist

• Save every Wi-Fi password you need, and screenshot any custom VPN or APN settings your carrier or employer gave you.
• Know your iPhone passcode; the reset cannot proceed without it. On a work or school iPhone, check with IT first.

What Problems Can Resetting Network Settings Fix?

A network reset fixes problems caused by corrupt settings on your iPhone. It cannot fix your router, ISP, or carrier network, so match the symptom to the cause first.

Symptoms a network reset can fix:

• Wi-Fi connects but shows “No Internet” on this iPhone while other devices work fine.
• Cellular data works for some apps but not others, or drops for no reason.
• Your iPhone shows “No Service” or “Searching” after an iOS update.
• A VPN that used to connect now fails or gets stuck, or Personal Hotspot turns on but other devices cannot join.
• You switched carriers and mobile data settings look wrong.

Symptoms it will not fix:

• Every device in the house is slow or offline. That is a router or ISP problem; restart the router first, and if the hardware itself is aging, our Wi-Fi 7 router buying guide walks through modern replacements.
• One specific website or app is down for everyone. That is a server problem, not your phone.

Fixes to try before the reset

Work through these quick checks first; most guides skip them and jump straight to the reset.

1. Toggle Airplane Mode on for 30 seconds, then off. This forces the iPhone to re-establish every radio connection.
2. Restart your iPhone. A surprising number of “corrupt settings” are just stuck processes.
3. Forget and rejoin the Wi-Fi network (Settings > Wi-Fi > tap the info icon > Forget This Network, then reconnect). This fixes single-network problems without touching everything else.
4. Turn off Wi-Fi Assist while troubleshooting. On some newer iOS versions this appears under a renamed “Connectivity Assist” label at Settings > Wi-Fi. It can mask weak Wi-Fi by silently switching you to cellular.
5. Update iOS and carrier settings. Check Settings > General > Software Update, then Settings > General > About and wait a few seconds; a carrier settings update prompt appears here if one is available.

Should You Reset Your Network Settings?

Use this decision flow before committing, since the reset wipes dozens of saved networks at once.

• Only your iPhone is affected, and only on one network? Forget and rejoin that network instead. A full reset is overkill.
• All your devices are affected? The problem is your router or ISP. Restart the router and contact your provider if it persists.
• The trouble started right after an iOS update? Install any pending carrier settings update and restart first.
• Is it a work or school iPhone? Ask your IT admin. Managed devices can block the reset or reapply the same broken settings afterward.
• Do you know your passcode, and have you saved your Wi-Fi passwords? Both are required before you proceed; the password recovery section above covers the second one.

If you answered yes to the iPhone-only question, tried the quick fixes, and saved your passwords, the reset is a reasonable next step. It takes under a minute, and most people reconnect to their main networks within ten minutes afterward.

How Do You Reset Network Settings on iPhone?

The steps below work on iOS 15 and later. iOS asks for your passcode, warns that the action cannot be undone, and restarts the phone when you confirm.

How to reset network settings on iOS 15 and later

1. Open the Settings app.
2. Tap General.
3. Tap Transfer or Reset iPhone.
4. Tap Reset at the bottom of the screen.
5. Tap Reset Network Settings.
6. Enter your passcode when prompted.
7. Tap Reset Network Settings again to confirm. Your iPhone restarts.

How to reset network settings on iOS 14 and earlier

On older iPhones the menu has a shorter name:

1. Open Settings.
2. Tap General.
3. Tap Reset (there is no “Transfer or Reset iPhone” menu on these versions).
4. Tap Reset Network Settings, enter your passcode, and confirm.

The reset takes less than a minute, followed by a normal restart. Wi-Fi and Bluetooth come back on but disconnected; cellular reconnects on its own within a minute or two.

What Happens After You Reset Network Settings?

The reset is only half the job; the ten minutes afterward determine whether you are back online or staring at a phone that will not connect. Work through this checklist in order.

1. Rejoin your Wi-Fi networks. Go to Settings > Wi-Fi, pick your network, and enter the password you saved earlier. Repeat for each network you use.
2. Check for a carrier settings update. Go to Settings > General > About and wait about 15 seconds. If your carrier has pushed new settings, a prompt appears; accept it.
3. Re-enter custom APN settings if your carrier uses them. Most carriers configure this automatically, but if yours gave you manual APN details, enter them under Settings > Cellular > Cellular Data Network.
4. Re-add manually configured VPNs under Settings > General > VPN & Device Management. Work or school VPNs installed via a profile usually reappear on their own.
5. Re-pair Bluetooth accessories if needed. Headphones, speakers, and car systems may need pairing again from Settings > Bluetooth.
6. Re-enable cellular data roaming if you travel. The reset may switch it off; check Settings > Cellular > Cellular Data Options > Data Roaming.
7. Do not tap “Delete All eSIMs.” It sits on the same Reset menu, and tapping it wipes your eSIM profiles. Your eSIMs survive a network reset untouched, so leave that option alone.

Wi-Fi passwords stored in iCloud Keychain remain available on your other Apple devices, but the reset iPhone itself still asks you to rejoin each network manually. If dead zones persist after a clean reset, the network itself is the limit; our Wi-Fi 7 mesh guide explains when a mesh system is the real fix.

How Is Reset Network Settings Different From Reset All Settings?

iOS offers three resets on the same menu, and mixing them up is the most common fear people have before tapping anything. The differences are straightforward.

Reset option	What it does	Your data
Reset Network Settings	Restores network defaults only: Wi-Fi, cellular, VPN, APN	Safe: photos, apps, messages untouched
Reset All Settings	Restores every setting to defaults: network, wallpaper, brightness, sounds, privacy, keyboard dictionaries, Home Screen layout	Safe: your files stay, but you reconfigure preferences
Erase All Content and Settings	Factory reset: wipes the entire iPhone	Everything deleted; the phone returns to out-of-box state

Erase All Content and Settings is the nuclear option: only use it when selling the phone, or as a last resort for software problems, and only after a full backup. Note that it can also remove eSIMs unless you choose to keep them, while a network reset never touches them.

What If the Reset Network Settings Option Is Greyed Out?

If the option is dimmed or missing, something is restricting it. The usual causes, in order of likelihood:

• Screen Time restrictions. Go to Settings > Screen Time > Content & Privacy Restrictions and check whether account or settings changes are blocked.
• A work or school management profile. MDM profiles can disable reset options entirely. Check Settings > General > VPN & Device Management for a profile, and ask your IT admin.
• A forgotten passcode. The reset requires the device passcode before it does anything; recover access through Apple’s account recovery first.
• The wrong menu. On iOS 14 and earlier the option lives under Settings > General > Reset, not under “Transfer or Reset iPhone.”

If none of these apply, update iOS to the latest version and try again; a pending update can occasionally lock settings menus until installed.

FAQs

Will resetting network settings delete my photos or contacts?

No. The reset only touches connection preferences: saved Wi-Fi networks and passwords, cellular and APN settings, and manually added VPN configurations. Your photos, videos, messages, contacts, apps, and documents are completely unaffected.

Will I lose my eSIM if I reset network settings?

No. eSIM profiles survive a network reset untouched. The confusion comes from the “Delete All eSIMs” option sitting on the same Reset menu; that is a separate action, so read carefully and tap only “Reset Network Settings.”

Can I undo a network settings reset?

No, there is no undo. Once confirmed, the saved networks and settings are gone for good. This is why the password recovery steps earlier in this guide matter: write down every Wi-Fi password before you tap confirm.

How long does resetting network settings take?

The reset itself takes under a minute, plus a normal iPhone restart. Budget another ten to fifteen minutes afterward to rejoin your Wi-Fi networks, check for a carrier settings update, and re-add any manual VPN or APN configurations.

Will resetting network settings fix slow Wi-Fi?

Only if the cause is corrupt settings on your iPhone. If your iPhone is slow but other devices are fast, a reset is worth trying. If every device is slow, the problem is your router or internet plan, and no iPhone setting will fix it.

Do I need my Apple ID password to reset network settings?

No. The reset asks for your device passcode, the code you type to unlock the phone, not your Apple ID password. If you do not know the passcode, you must recover it first; the reset cannot proceed without it.

Conclusion

Resetting network settings on an iPhone is the right middle ground between toggling Wi-Fi and wiping the whole phone: it clears corrupt connection preferences and restores Apple’s network defaults in under a minute, without touching your photos, messages, or apps. Save your Wi-Fi passwords first, follow the steps for your iOS version, and work through the post-reset checklist so you are back online in minutes.
