You reset network settings on your iPhone by going to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings, then entering your passcode. This clears every saved Wi-Fi password, Bluetooth pairing, VPN, and APN configuration, and the phone reboots in about 1 to 3 minutes. It does not delete your photos, apps, contacts, or messages.
Now, if you're here because your iPhone is refusing to connect to Wi-Fi, dropping calls, or just acting weird with cellular data, I get it. It's frustrating. You restart the thing, cross your fingers, and the problem is still sitting there staring back at you.
The good news: Apple built a dedicated fix for exactly this. Let's walk through how it works, what it erases, and when you should actually use it.
Before you go tapping buttons, let's talk about what this feature is doing behind the scenes.
A network settings reset wipes your iPhone's stored connectivity configurations and puts them back to factory default. Think of it as clearing out a messy drawer full of tangled cables, except the drawer is your phone's memory of every Wi-Fi network, Bluetooth device, and VPN it has ever touched.
According to Apple's own support documentation, this reset removes saved Wi-Fi networks and passwords, cellular settings, and VPN and APN configurations. It also renames your device back to plain "iPhone" and untrusts any manually approved certificates.
This is different from a full factory reset. You're not wiping your phone. You're only clearing its networking memory.
I know this is the question everyone actually cares about, so let's answer it straight away.
No. Your photos, videos, contacts, messages, and apps are completely safe. This reset only touches connectivity-related data, not your personal content.
Multiple sources confirm this, including a breakdown from ComputerCity, which states plainly that this reset "does not delete personal data such as photos or apps." A separate explainer from FoneGeek echoes the same thing: your media, contacts, and text messages remain untouched.
What you will lose is anything tied to how your phone talks to the outside world:
Every saved Wi-Fi password
Bluetooth pairings with your headphones, speakers, or car
VPN configurations
APN (carrier) settings
Cellular roaming preferences
So yes, be ready to log back into your favorite coffee shop Wi-Fi and re-pair your AirPods. Small price to pay for a clean slate.
Not every hiccup needs this treatment, honestly. Sometimes a plain restart does the trick, so it's worth ruling out the easy stuff first — see our guide on what a CRC error means for another example of how a simple reset often fixes connectivity-style errors before you escalate.
Consider a network reset when you're dealing with persistent issues like:
Wi-Fi that won't connect, or keeps dropping randomly
"No Service" messages that won't go away
Cellular data that's painfully slow or not working at all
Bluetooth devices refusing to pair
VPN or hotspot connections acting glitchy
Apple actually recommends this only after simpler fixes fail. Per their Wi-Fi troubleshooting guide, you should reset network settings "only if other solutions fail," and if you're on a school or work network, check with your IT administrator first, since managed configuration profiles can behave unpredictably after a reset.
One more thing: if your iPhone shows it's connected to Wi-Fi but you still can't get online, the problem might not even be your phone. It could be your router or your ISP. Worth ruling that out first.
Alright, let's actually do this thing.
Here's the exact path, confirmed by Verizon's support page and EE's device guide:
Open Settings — tap the gear icon on your Home Screen.
Tap General — scroll until you find it, usually near the top.
Tap "Transfer or Reset iPhone" — this is where Apple tucked away all the reset options.
Tap Reset — you'll see a list of different reset types. Don't panic, keep going.
Tap "Reset Network Settings" — this is the specific one you want, not "Erase All Content" or "Reset All Settings."
Enter Your Passcode — Apple wants to confirm it's really you.
Wait for the Reboot — your iPhone restarts automatically, usually within 1 to 3 minutes.
Once it powers back on, your network settings are back to factory default and ready for a clean start.
If you're on an older iPhone or haven't updated in a while, the path is a bit shorter. According to the University of Wisconsin's IT knowledge base, older versions skip the "Transfer or Reset iPhone" step entirely:
Tap Settings
Tap General
Tap Reset
Tap Reset Network Settings
Enter your passcode
Same result, just fewer taps to get there.
Your phone rebooted. Now what? Here's what to expect — and none of it is a big deal.
Every saved network is gone. If you use iCloud Keychain, some passwords might sync back automatically, but don't count on it for every network. Keep a note of your important passwords before you reset, just in case.
Your AirPods, car stereo, and smartwatch all need pairing again. It takes about a minute per device, so no real hassle.
If you use a VPN for work or privacy, you'll need to log back in and reconfigure it. Same goes for custom APN settings if your carrier requires them.
This one catches people off guard. On certain models, a workflow explained by UPeSIM's guide notes you may need to reinstall your eSIM profile through your carrier's app after resetting — worth checking if you rely on an eSIM for your primary line.
These three options sound similar but are wildly different, so let's clear up the confusion with a quick side-by-side.
Reset Type | What It Erases | Personal Data Affected? |
|---|---|---|
Reset Network Settings | Wi-Fi, Bluetooth, VPN, APN, cellular preferences | No |
Reset All Settings | Everything above, plus keyboard dictionary, Home Screen layout, location and privacy permissions | No |
Erase All Content and Settings | Everything on the device | Yes, completely wiped |
If you're weighing a deeper reset because of a hardware-level issue rather than just Wi-Fi, our BIOS boot order guide is a useful parallel for anyone troubleshooting startup and configuration issues across devices.
If you just need to fix a connectivity issue, stick with the network-only option. Save the nuclear option for when you're actually selling or giving away your phone.
Sometimes the problem survives the reset. It happens. Here's what to try next.
Check for a software update. Go to Settings > General > Software Update. An outdated iOS version can cause connectivity bugs a network reset alone won't fix.
Restart your router. Unplug it, wait 30 seconds, plug it back in. Old-school, but it works more often than you'd think.
Remove problematic VPN or security apps. Per Apple's Wi-Fi troubleshooting page, certain VPN or security software can interfere with your connection even after a reset. Try uninstalling, restarting, and testing again.
Contact your carrier. If cellular data specifically isn't working, your carrier might have an outage or account issue that no amount of phone-tinkering can solve.
Contact your ISP. If your iPhone shows it's connected to Wi-Fi but nothing loads, and other devices on the same network have the same problem, the issue is likely your internet provider, not your phone at all. If you're troubleshooting a device that won't power on or respond at all, our guide on what to do when your computer won't turn on covers a similar step-by-step diagnostic approach
Does resetting network settings delete my photos or apps?
No. Your photos, apps, contacts, and messages stay completely intact. Only network-related configurations get erased.
Will I lose my Wi-Fi passwords?
Yes. Every saved Wi-Fi password gets wiped, so you'll need to re-enter them manually or rely on iCloud Keychain if you have it enabled.
Do I need to re-pair my Bluetooth devices afterward?
Yes, every paired device needs to be reconnected from scratch. It's quick, but it's an extra step.
How long does the reset take?
Usually between 1 and 3 minutes, including the automatic restart.
What's the difference between Reset Network Settings and Reset All Settings?
Reset Network Settings only touches connectivity. Reset All Settings goes further and also resets your keyboard dictionary, Home Screen layout, and privacy permissions, though it still keeps your personal content safe.
Will this fix a "No Service" error?
Often, yes. A network settings reset is one of the most effective fixes for persistent "No Service" issues, especially if a carrier settings update or software update hasn't already solved it.
Dealing with connectivity issues on your iPhone is annoying, but resetting your network settings is genuinely one of the safest and most effective troubleshooting steps you have. It won't touch your photos, apps, or messages — it just clears out the digital clutter that's likely causing your Wi-Fi or cellular headaches.
Write down your important Wi-Fi passwords first, run through the steps above, and you should be back online without much fuss. And if it doesn't fix things right away, you now know exactly what to try next.
