How to Reset Network Settings on Samsung
Last updated: April 2026
Resetting network settings on a Samsung phone clears all saved WiFi networks, Bluetooth pairings, mobile data settings, and VPN configurations. It is one of the most effective troubleshooting steps for connectivity issues — and it does not delete any of your personal data, apps, or files.
Here is how to do it and when you should.
Steps to Reset Network Settings
Step 1: Open the Settings app.
Step 2: Scroll down and tap General management.
Step 3: Tap Reset.
Step 4: Tap Reset network settings.
Step 5: If you have multiple SIMs, select which SIM's settings you want to reset. If you only have one SIM, skip this step.
Step 6: Tap Reset settings. You may need to enter your PIN, pattern, or password to confirm.
Step 7: Your phone will reset all network settings and restart. This takes about 30 seconds.
What Gets Reset
A network settings reset clears the following:
- Saved WiFi networks and passwords — You will need to re-enter WiFi passwords for your office, home, and any other saved networks
- Bluetooth pairings — All paired devices (headsets, car systems, printers, speakers) will be unpaired and need to be reconnected
- Mobile data settings — APN settings, preferred network mode, and data roaming preferences return to defaults
- VPN configurations — Any configured VPN connections will be removed
- Tethering and hotspot settings — Hotspot name and password will revert to defaults
What Does NOT Get Reset
- Your apps, photos, messages, and files are untouched
- Your contacts and call history remain intact
- App data and login sessions are not affected
- Your SIM card and phone number are not affected
- System settings (display, sound, etc.) stay the same
This is not a factory reset — it only affects network-related settings.
When to Reset Network Settings
After a SIM swap
If you have just inserted a new SIM card or switched from one provider to another, old APN and network settings from the previous SIM can sometimes interfere. A network settings reset clears these out and lets the new SIM configure fresh settings automatically.
Persistent connectivity issues
If your phone keeps dropping WiFi, losing mobile signal, or failing to connect to Bluetooth devices despite restarting, a network settings reset often resolves the issue. It clears any corrupted network configurations that a simple restart cannot fix.
After a major software update
Occasionally, a One UI or Android update can cause network-related bugs. If your phone's connectivity became unreliable after an update, resetting network settings is a quick and safe first step before more drastic troubleshooting.
Mobile data not working
If your mobile data suddenly stops working — no 4G or 5G connection despite having signal — it is often an APN configuration issue. Resetting network settings restores the default APN settings for your SIM, which usually fixes the problem immediately.
WiFi keeps disconnecting
If your phone connects to WiFi but keeps dropping the connection, a network settings reset clears any corrupted WiFi profiles. After the reset, reconnect to your WiFi network with the password and see if the issue is resolved.
After the Reset
Once your phone restarts:
- Reconnect to WiFi — Go to Settings > Connections > WiFi and select your network. You will need the password.
- Re-pair Bluetooth devices — Go to Settings > Connections > Bluetooth and pair your devices again.
- Check mobile data — Mobile data should reconfigure automatically. If it does not, restart your phone once more. If data still does not work, contact your network provider for the correct APN settings.
- Reconfigure VPN — If you use a VPN for work, you will need to set it up again. Contact your IT department for the connection details.
