Samsung now separates network resets into two different options:
- Reset mobile network settings
- Reset Wi-Fi and Bluetooth settings
That distinction matters because you no longer need to wipe every saved WiFi network and Bluetooth pairing just to troubleshoot mobile data, calls, or SIM registration.
Use the reset that matches the problem.
Which Reset Should You Use?
Choose Reset mobile network settings when the problem involves:
- mobile data;
- calls;
- SMS;
- carrier registration;
- SIM or eSIM connectivity;
- APN-related mobile service issues.
Choose Reset Wi-Fi and Bluetooth settings when the problem involves:
- WiFi connection failures;
- saved WiFi networks;
- Bluetooth pairing;
- earbuds, watches, speakers, or car connections.
Do not reset both unless both types of connection are actually affected.
How to Reset Mobile Network Settings on Samsung
On current Galaxy phones:
- Open Settings.
- Tap General management.
- Tap Reset.
- Tap Reset mobile network settings.
- Review the information.
- Tap Reset settings.
- Enter your PIN, password, or pattern if prompted.
- Tap Reset to confirm.
Samsung says this restores mobile network settings to their defaults without deleting apps or personal data.
This can help with:
- mobile data not working;
- calls dropping;
- no network signal;
- incorrect carrier settings;
- SIM registration problems.
If the phone says Mobile Network Not Available, use Mobile Network Not Available on Android first so you can rule out outages, SIM problems, carrier locks, and provisioning issues before resetting anything.
How to Reset Wi-Fi and Bluetooth Settings on Samsung
Use this when WiFi or Bluetooth is the problem.
- Open Settings.
- Tap General management.
- Tap Reset.
- Tap Reset Wi-Fi and Bluetooth settings.
- Review the warning.
- Tap Reset settings.
- Confirm the reset.
Afterward, you will need to reconnect to WiFi networks and pair Bluetooth accessories again.
Samsung specifically notes that saved WiFi and Bluetooth connection information is affected by this reset.
What Gets Deleted by the Wi-Fi and Bluetooth Reset?
Expect to reconnect:
- WiFi networks;
- saved WiFi passwords;
- Bluetooth headphones;
- speakers;
- watches;
- car systems;
- other paired Bluetooth devices.
If you do not remember an important WiFi password, check How to Find Saved WiFi Passwords on Android before performing the reset.
What Does the Mobile Network Reset Change?
A mobile network reset returns carrier-related network settings to their defaults.
This may affect:
- mobile network preferences;
- carrier network selection;
- APN configuration;
- cellular connection settings.
Samsung notes that custom APN settings may need to be configured again after a mobile-network reset.
If your carrier gave you a manual APN, record it before resetting.
What Does Not Get Deleted?
Neither of these network resets is a factory reset.
They do not normally delete:
- photos;
- videos;
- contacts;
- messages;
- installed apps;
- documents;
- Google Account data;
- Samsung Account data.
Your personal files stay on the phone.
That is why a network reset is much less disruptive than a factory reset.
Reset Mobile Network Settings vs Reset Wi-Fi and Bluetooth
The difference is simple.
Reset mobile network settings targets the cellular side of the phone.
Use it for:
- mobile data;
- calls;
- SIM/eSIM registration;
- carrier settings.
Reset Wi-Fi and Bluetooth settings targets local wireless connections.
Use it for:
- WiFi;
- Bluetooth;
- paired accessories.
Older Samsung guides sometimes describe these as one combined network reset. On current One UI software, Samsung documents them separately.
When a Mobile Network Reset Is Worth Trying
Use it after simpler checks fail.
For mobile problems, first try:
- Turn Airplane mode on and off.
- Restart the phone.
- Check whether your carrier has an outage.
- Make sure the SIM or eSIM is enabled.
- Confirm the correct SIM is selected on dual-SIM phones.
- Install pending software updates.
If the issue continues, a mobile-network reset becomes reasonable.
For a data-only problem, see Mobile Data Not Working on Android before assuming the whole mobile network configuration is broken.
When a Wi-Fi and Bluetooth Reset Is Worth Trying
Use it when:
- the phone repeatedly fails to connect to known WiFi networks;
- Bluetooth devices refuse to pair;
- saved pairings behave incorrectly;
- WiFi or Bluetooth became unstable after an update;
- forgetting and reconnecting one device did not help.
If only one WiFi network is failing, test another network first.
If Android shows WiFi connected but there is no internet access, use Wi-Fi Connected but No Internet on Android before resetting all saved wireless connections.
When You Should Not Reset Network Settings
A network reset cannot fix:
- a carrier outage;
- a broken router;
- damaged SIM hardware;
- a suspended mobile account;
- a damaged phone antenna;
- a faulty Bluetooth accessory;
- a physically damaged WiFi or cellular radio.
It also should not be the first response when only one app has an internet problem.
Test whether the problem affects the entire phone first.
What About APN Settings?
APN settings matter mainly for mobile data and carrier services.
If calls and SMS work but mobile internet does not, checking or resetting the APN can be useful.
Samsung currently provides:
Settings > Connections > Mobile networks > Access Point Names
From there, the menu can offer Reset to default.
Use your carrier’s official APN settings if manual configuration is required.
Do not copy random APN values from unrelated carriers or regions.
Does the Phone Restart After a Network Reset?
A mobile or WiFi/Bluetooth reset does not always behave exactly the same across every Galaxy model and One UI version.
Follow the on-screen instructions.
After the reset, restarting the phone manually is reasonable if the connection does not reinitialize properly.
If the Reset Does Not Fix the Problem
The next step depends on what is still failing.
Mobile network still fails
Check:
- carrier outage;
- SIM/eSIM activation;
- carrier account status;
- SIM in another phone;
- another active SIM in your phone;
- carrier lock;
- hardware.
WiFi still fails
Check:
- another WiFi network;
- router restart;
- router security settings;
- software updates;
- whether other devices can connect.
Bluetooth still fails
Test another accessory.
If only one device fails, remove and re-pair that device rather than repeatedly resetting the whole phone.
Do Not Factory Reset the Phone Just Because Network Reset Failed
A factory reset is far more disruptive and often irrelevant.
Before considering it, prove that:
- the carrier or router is not the cause;
- the SIM or accessory works elsewhere;
- software is current;
- the correct Samsung network reset was used;
- the problem follows the phone across networks or accessories.
If the evidence points to hardware, a factory reset is unlikely to help.
The Simple Rule
Use:
Reset mobile network settings for cellular problems.
Reset Wi-Fi and Bluetooth settings for WiFi or Bluetooth problems.
Current Samsung software separates these options, so you can reset only the part of the network stack that is actually failing instead of erasing unrelated connection settings.
