What Does Resetting Network Settings Do? (Safe Guide)

Resetting network settings puts Wi-Fi, Bluetooth, VPN, and mobile network settings back to defaults, and a mobile network reset on Android does the same for cellular settings only. Both are safe for your data: photos, apps, contacts, and messages stay. On iPhone, eSIMs stay installed. On Android, eSIMs stay unless you tick Erase eSIMs.

Your phone won't connect to Wi-Fi. Mobile data keeps dropping. You've restarted twice and nothing's changed. Someone online says to "just reset your network settings," but what does that actually mean, and is it safe to do?

Here's the longer breakdown, with the exact steps for iPhone and Android and what to check afterward if you rely on a travel eSIM.

What Resetting Network Settings Actually Does #

It wipes all saved network configuration on your phone and restores it to factory defaults. That's the whole thing. Your apps, photos, contacts, and files stay exactly where they are.

Here's what gets erased:

• Wi-Fi networks and passwords: every saved network disappears
• Bluetooth pairings: headphones, car, speakers, all unpaired
• Mobile data settings: carrier configurations and any custom settings
• VPN configurations: saved VPN profiles are removed (on iPhone, VPNs installed by a work profile or MDM stay)
• Cellular plan settings: including any manually adjusted network preferences. On iPhone, Apple notes that cellular data roaming may also be turned off

Apple also resets the device name to "iPhone" and marks manually trusted certificates as untrusted (Apple Support, checked October 5, 2026). Your personal data is untouched.

What It Does NOT Delete #

This is the part most people worry about for no reason.

Resetting network settings does not delete:

• Photos or videos
• Apps or app data
• Contacts or messages
• Passwords saved in your password manager or browser
• Downloaded files or music
• Your Apple ID, Google account, or any other login

Think of it as clearing only the network layer of your phone. Everything else stays put.

What does reset mobile network settings do? #

Resetting mobile network settings puts your phone's cellular setup back to defaults: carrier connection settings, access point names (APNs), and data usage limits are reset, and the phone reconnects to the mobile network. It is safe for your data, because photos, apps, contacts, and messages are not touched, and on Android your eSIMs stay unless you tick Erase eSIMs.

On Android phones such as Pixel, this is its own option at Settings > System > Reset options > Reset Mobile Network Settings (Pixel Phone Help). Android's source code shows it resets connectivity, VPN, calling (IMS), and data usage settings, plus the APN for the SIM you pick (Android source, checked October 6, 2026). Wi-Fi and Bluetooth are reset separately, under Reset Bluetooth & Wi-Fi.

On iPhone there is no mobile-only option. Reset Network Settings covers cellular, Wi-Fi, and VPN settings together, and Apple notes that cellular data roaming may also be turned off (Apple Support).

Travel tip: if your travel eSIM needed an APN typed in by hand, enter it again after the reset, then check that data roaming is on for that line.

When You Should Reset Network Settings #

Not every connectivity problem calls for this fix. But in certain situations, it's exactly the right move.

Your Wi-Fi Keeps Disconnecting or Won't Connect #

If your phone repeatedly drops a connection or refuses to join a network even with the correct password, corrupted network data is usually the culprit. A reset clears it out and lets your phone start fresh.

Mobile Data Stopped Working After a Carrier Update #

Carrier updates sometimes push new settings to your device. If something goes wrong during that process, your data connection can break. Resetting forces your phone to re-establish those carrier configurations from scratch.

Bluetooth Devices Won't Pair or Stay Connected #

Persistent Bluetooth problems, such as a device that shows as connected but plays no audio or pairings that keep failing, are often fixed by a network reset followed by re-pairing.

You Just Installed a New SIM or eSIM #

This one matters for travelers. If you've installed a new eSIM and data isn't connecting, a network settings reset can help your phone recognize and apply the new configuration correctly.

Your Phone Was Used Abroad and Now Acts Strangely #

Moving through multiple countries means your phone picks up a lot of carrier and roaming data along the way. If things feel off once you're home, a reset clears that accumulated clutter.

How to Reset Network Settings on iPhone #

1. Open Settings
2. Tap General
3. Scroll to Transfer or Reset iPhone
4. Tap Reset
5. Choose Reset Network Settings
6. Enter your passcode if prompted
7. Confirm

Your phone restarts and all network settings are cleared. Your eSIMs are not touched: Apple lists Delete All eSIMs as a separate reset option (Apple Support).

How to Reset Network Settings on Android #

The path varies slightly by manufacturer, but the general route is:

1. Open Settings
2. Go to General Management (Samsung) or System (stock Android)
3. Tap Reset
4. Select Reset Network Settings or Reset Wi-Fi, Mobile & Bluetooth
5. Confirm

On Samsung Galaxy devices specifically: Settings > General Management > Reset > Reset Network Settings. On recent Pixel phones, go to Settings > System > Reset options > Reset Mobile Network Settings (Pixel Phone Help). Pixels reset Wi-Fi and Bluetooth separately, under Reset Bluetooth & Wi-Fi.

What Happens to Your eSIM After a Network Reset? #

Short answer: a network reset does not delete your eSIM on iPhone, and on Android it only does if you choose to.

iPhone: Reset Network Settings removes network settings only. Deleting eSIMs is a different option in the same menu, called Delete All eSIMs, which Apple says removes all eSIMs stored on the phone (Apple Support: Reset iPhone settings, checked October 5, 2026). Apple also advises not to erase an eSIM as a troubleshooting step unless your carrier tells you to (Apple Support: How to erase an eSIM).

Android: In the Reset Mobile Network Settings screen, an Erase eSIMs checkbox appears on phones that support eSIM. It starts unchecked, and Android only wipes eSIMs when you tick it (Android source code for the reset screen, checked October 5, 2026). Menu names vary by brand, so read the confirmation screen and leave any eSIM option unchecked if you want to keep your plans.

Once the reset completes, check your plan is still there and switched on. Go to Settings > Cellular on iPhone or Settings > Connections > SIM Manager on Samsung to confirm your eSIM profile is listed and active. If you're abroad, also make sure data roaming is turned back on for your travel eSIM, since the reset can switch it off.

If you're traveling and relying on a travel eSIM for data, do this check before you head out. The last thing you want is to land in Tokyo 🇯🇵 or Rome 🇮🇹 with no data because roaming got switched off.

Should You Reset Network Settings Before or After Installing a Travel eSIM? #

You don't need to reset before installing a travel eSIM. The installation process is straightforward on compatible devices.

If your eSIM installs but data doesn't activate, that's when a network settings reset becomes a useful troubleshooting step. It clears any conflicting settings that might be blocking the new plan from working.

If you're shopping for a travel plan, Roamify sells eSIMs for 200+ destinations, including call and SMS plans in almost all countries (Japan plans are data only). You can install it from our iOS or Android app and top up an active eSIM if you run low. If you hit an activation issue, the steps above are a good first fix.

When a Network Reset Won't Help #

A reset fixes software-level configuration problems. It won't do anything if:

• Your physical SIM card is damaged or the SIM tray is faulty
• Your carrier account has a billing issue or suspension
• Your device has a hardware problem with its antenna
• You're somewhere with no signal coverage

If the reset doesn't solve it, the problem is almost certainly outside the network settings layer entirely.

Quick Reference: Reset Network Settings Checklist #

Before you reset, do these three things:

1. Note your Wi-Fi passwords: you'll need to re-enter them afterward
2. Check your eSIM is still active once the reset completes
3. Re-pair your Bluetooth devices after the phone restarts

Then reconnect to Wi-Fi, confirm mobile data is working (turn data roaming back on if you're abroad), and you're done.

FAQs #

What does resetting network settings do?
A full network reset clears saved Wi-Fi networks and passwords, Bluetooth pairings, VPN settings, and mobile network preferences. On iPhone it also resets the device name and may turn off data roaming. For the Android option that resets only cellular settings, see the mobile network section above.

Does resetting network settings delete my eSIM?
No on iPhone: Delete All eSIMs is a separate reset option (Apple Support). On Android, eSIMs are only erased if you tick the Erase eSIMs checkbox, which starts unchecked (Android source). Afterward, check your eSIM is still switched on for data.

Will I lose photos, apps, or contacts?
No. A network reset only touches network settings. Photos, apps, contacts, messages, and files are not deleted. That is different from Erase All Content and Settings on iPhone or a factory reset on Android, which wipe the phone.

Does a network reset delete Wi-Fi passwords?
Yes. All saved Wi-Fi networks and their passwords are removed, so make sure you know the ones you need, or have access to your router, before you reset.

How do I reset network settings on iPhone?
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings, enter your passcode, and confirm (Apple Support). Your iPhone restarts when it's done.

How do I reset network settings on Android without erasing eSIMs?
On Pixel, go to Settings > System > Reset options > Reset Mobile Network Settings (Pixel Phone Help). On Samsung, go to Settings > General Management > Reset > Reset Network Settings. In either case, leave any Erase eSIMs option unchecked before you confirm.

Should I reset network settings before installing a travel eSIM?
No, you don't need to. Install the eSIM first. If it installs but data doesn't connect, check that the eSIM is selected for mobile data and that data roaming is on. If it still won't connect, a network reset is a sensible next step.

Is it safe to reset network settings?
Yes, for your personal data. Apple's own description says Reset Network Settings removes network settings, while deleting eSIMs and erasing content are separate options. The only cost is re-entering Wi-Fi passwords and re-pairing Bluetooth devices.

Resetting network settings is a simple, safe fix for a specific set of problems. It takes under a minute, touches nothing personal, and solves more connectivity issues than most people expect. If your phone is acting up on Wi-Fi, Bluetooth, or mobile data, this is often the fastest path back to normal.
