Reset Network Settings on Samsung: A Business User's Guide for S10, S22, S23, S24 and S25

Reset Network Settings on Samsung: A Business User's Guide for S10, S22, S23, S24 and S25

Last updated: April 2026

Most mobile signal problems are not network problems. They are phone problems. The single most useful troubleshooting step we give to business clients before they call their network's support line is "reset network settings on the phone first". About 70% of the time, that alone fixes the issue.

This guide covers how to reset network settings on every current Samsung Galaxy S-series phone still in use on UK business accounts, when to do it, what it actually does, what it does not do, and what to try next if it does not work.

What "Reset Network Settings" Actually Does

Reset network settings clears:

  • Wi-fi networks and saved passwords
  • Bluetooth paired devices
  • Mobile network preferences (manual selections, preferred network type)
  • APN settings (back to carrier default)
  • VPN settings (configuration only, not the VPN apps themselves)

It does NOT clear:

  • Photos, files, apps, contacts, or any personal data
  • Google or Samsung account sign-in
  • Your SIM card or eSIM profile itself
  • Carrier settings updates applied by the network

It is a safe thing to do. The worst that happens is you have to reconnect to your office wi-fi and re-pair your wireless headphones.

When to Reset Network Settings

Good candidates for a network reset:

  • No signal after changing SIMs or switching networks
  • Wi-fi not connecting when other devices work fine on the same wi-fi
  • Calls dropping repeatedly in places that previously worked
  • Data not working even when signal looks strong
  • Bluetooth pairing failures with car kits or headsets
  • VoLTE or Wi-Fi Calling suddenly stopped working
  • Phone stuck on 2G or 3G when 4G or 5G should be available
  • Just ported a number and things are not quite right
  • Just returned from abroad and the phone is still acting as if it's roaming
  • Manual network selection was set and should now be automatic

How to Reset Network Settings on Samsung Galaxy S10

The S10 launched on Android 9 and will typically be on Android 12 in 2026 (last officially supported update).

  1. Open Settings
  2. Tap General management
  3. Tap Reset
  4. Tap Reset network settings
  5. Tap Reset settings
  6. Enter your PIN/pattern/password if prompted
  7. Tap Reset to confirm

The phone will restart briefly. When it comes back, data roaming is off by default, wi-fi is disconnected, and all mobile network preferences are reset to carrier defaults.

How to Reset Network Settings on Samsung Galaxy S22 and S23

The S22 and S23 run One UI 5/6 on current firmware.

  1. Open Settings
  2. Tap General management
  3. Tap Reset
  4. Tap Reset mobile network settings (on some One UI 6 builds this is combined with wi-fi and bluetooth into one option called Reset network settings)
  5. Tap Reset settings
  6. Confirm with PIN/biometric

Same as the S10, the phone restarts and network preferences reset to defaults.

How to Reset Network Settings on Samsung Galaxy S24

The S24 series runs One UI 6.1 out of the box, updated to One UI 7 in 2025.

  1. Open Settings
  2. Tap General management
  3. Tap Reset
  4. Tap Reset network settings
  5. Tap Reset settings
  6. Confirm with PIN/biometric

How to Reset Network Settings on Samsung Galaxy S25

The S25 series ships with One UI 7 on Android 15.

  1. Open Settings
  2. Tap General management (on some regional firmware this is called System)
  3. Tap Reset
  4. Tap Reset network settings
  5. Tap Reset settings
  6. Confirm with PIN or Samsung Pass biometric

The S25 process is functionally identical to S22-S24, just with slightly different icons and animations.

Changing Network Selection on Samsung (Including S10)

Sometimes the real problem is not that the settings need reset — you just want the phone to stop using one network and try another. This is a separate menu. It is the same across every Galaxy S phone from S10 to S25:

  1. Open Settings
  2. Tap Connections
  3. Tap Mobile networks
  4. Tap Network operators
  5. Turn off Select automatically
  6. Wait for the phone to scan — you will see a list of available networks
  7. Tap the network you want to connect to
  8. Wait up to 30 seconds for the phone to attach

Important: If you are in the UK on a UK SIM, always keep "Select automatically" turned ON unless your carrier tells you otherwise. Manually picking a network means the phone will not fall back to partner networks for coverage, which makes signal worse in most cases, not better.

Manual network selection is useful in only two scenarios:

  1. You are abroad and want to force the phone onto a specific partner for rate reasons.
  2. A specific network is causing repeated drops and you want to blacklist it temporarily.

For everyday UK business use, keep it automatic.

Troubleshooting Signal Problems: Order of Operations

When a user reports "my phone isn't working", here is the order we give them:

  1. Toggle airplane mode off and on (15 seconds off, then back on). Fixes half of everything.
  2. Restart the phone. Fixes a quarter of everything.
  3. Check data roaming is on if expected, off if not expected. Common cause of "no data abroad" or "huge bill after a border crossing".
  4. Check preferred network type — Settings > Connections > Mobile networks > Network mode. Set to 5G/LTE/3G/2G auto (or whatever is the newest available auto mode on your phone).
  5. Reset network settings (the procedure above).
  6. Remove and reinsert the SIM (or for eSIM, remove and re-add the profile via QR code if you have it; otherwise phone your network).
  7. Check for carrier settings update. Settings > About phone > Software update.
  8. Check for a firmware update. Settings > Software update > Download and install.
  9. Only then call the network.

Step 5 (network settings reset) is the single most effective step after the first two trivial ones. We have seen it fix VoLTE, Wi-Fi Calling, roaming stuck on wrong country, failed porting activation, stuck manual network selection, stuck APN, and persistent Bluetooth pairing issues.

eSIM vs Physical SIM After a Reset

If your Samsung uses a physical SIM, resetting network settings does not affect the SIM itself. The SIM keeps working.

If your Samsung uses eSIM, resetting network settings keeps the eSIM profile installed and active. The profile is not deleted. However:

  • Data roaming defaults to OFF after a reset. Toggle it back on if needed.
  • Preferred SIM for data, calls and messages resets to whatever the phone picks as default. Check this in Settings > Connections > SIM manager.
  • On dual-eSIM phones (S23+, S24+, S25+), the default for each service may flip to the wrong SIM. Re-check each setting after reset.

If a Reset Does Not Fix It

If you have reset network settings, restarted, checked roaming, checked preferred network type, and it still does not work, the problem is probably one of:

  1. Actual network outage — check your carrier's status page or Downdetector.
  2. SIM fault — try the SIM in another phone. If it does not work there either, request a SIM swap from your carrier.
  3. Handset hardware fault — antenna, modem or motherboard issue. Samsung repair or warranty.
  4. Locked to wrong carrier — some second-hand handsets are locked. Check IMEI status with the carrier.
  5. Blocked IMEI — if the phone was reported lost or stolen. Check on IMEIpro.info or similar.
  6. Account-side issue — the network has suspended the line for billing, fraud review, or porting in progress. Call business support.

For business mobile accounts we handle items 1, 4, 5 and 6 directly on behalf of clients. If your line is being difficult and you are on a business contract we arranged, call us first.

Business vs Consumer Samsung Setup

A couple of things that are different on business Samsung devices:

  • Knox — your company's Knox policies may restrict what you can do. Some businesses lock network settings so users cannot change them. If "Reset network settings" is greyed out, Knox is the reason.
  • Managed configuration — MDM-enrolled devices receive APN and Wi-Fi settings pushed from your IT department. A reset will revert to carrier defaults, then the MDM should re-push the managed config within 15-30 minutes.
  • Samsung Enterprise Edition — certain SKUs have extended support and different default settings. The reset procedure is the same.

See Samsung Enterprise Edition Guide for the business-specific detail.

Frequently Asked Questions

Q: Does resetting network settings delete my photos or contacts?

No. Network settings reset only affects network-related settings (wi-fi, bluetooth, mobile network, APN). Your personal data is untouched.

Q: Will I lose my eSIM if I reset network settings?

No. The eSIM profile stays installed and active. You may need to re-enable data roaming and re-set the default SIM for data or calls.

Q: How often should I reset network settings on my Samsung?

Only when troubleshooting a specific problem. There is no routine benefit. If it is working, leave it alone.

Q: Why does my Samsung S24 keep dropping to 3G?

Usually preferred network type is set wrong. Go to Settings > Connections > Mobile networks > Network mode and set it to 5G/LTE/3G/2G (auto connect). If that does not fix it, reset network settings and check again.

Q: I reset network settings but my Wi-Fi Calling still won't turn on.

Wi-Fi Calling requires both the network to support it and the account to have it provisioned. On business accounts, some networks (including O2 and Three) require the line to be manually enabled for Wi-Fi Calling. Call business support and ask for it to be switched on.

Q: Does a network reset fix manual network selection being stuck?

Yes. After a reset, the phone returns to automatic network selection on power-up.

Q: My Samsung is on a company Knox policy and Reset network settings is greyed out.

Your IT department has disabled it. You will need to ask them to perform the reset via MDM or to temporarily lift the policy.
