If Samsung Wi-Fi Calling is not working, first make sure your Galaxy phone, carrier, SIM or eSIM, and Wi-Fi network all support the feature. Then check that Wi-Fi Calling is enabled, restart the phone, install available software updates, and test another Wi-Fi network. If the Wi-Fi Calling option is completely missing, your carrier, plan, device model, or region may not support the service.
Samsung explains that Wi-Fi Calling lets supported Galaxy phones make and receive calls over a Wi-Fi connection when cellular coverage is weak or unavailable. Samsung Wi-Fi Calling support
Before You Start: Check Carrier Support
Wi-Fi Calling is not automatically available on every Samsung Galaxy phone.
Support can depend on:
- Your carrier
- Your Galaxy model
- Your mobile plan
- Your SIM or eSIM
- Your country or region
- Carrier provisioning
This means a setting found in a tutorial may not appear on your phone.
If you cannot find Wi-Fi Calling at all, contact your carrier and ask whether Wi-Fi Calling is supported and activated for your exact Galaxy model and mobile plan.
How to Turn On Wi-Fi Calling on Samsung
On many Galaxy phones, go to:
Settings → Connections → Wi-Fi Calling
Turn Wi-Fi Calling on.
Depending on your Galaxy model, One UI version, and carrier, you may also find it through:
Phone app → ⋮ → Settings → Wi-Fi Calling
Some models may also provide Wi-Fi Calling through Quick Settings.
Samsung’s menus can vary between devices, so don’t worry if the wording or location is slightly different.
Samsung Wi-Fi Calling Not Working? Try These Fixes
1. Make Sure Your Wi-Fi Actually Works
Wi-Fi Calling still needs a usable internet connection.
Open a website or video on your phone to confirm that Wi-Fi is working. If other apps are also struggling to connect, the problem may be your internet rather than Samsung’s Wi-Fi Calling feature.
If your internet keeps disconnecting, see our guide on why your internet keeps going out.
Try this: Move closer to the router and test Wi-Fi again.
2. Check Your SIM or eSIM
Your carrier must be able to identify and provision your mobile line correctly.
If you recently:
- Changed your SIM
- Switched carriers
- Moved to an eSIM
- Changed your mobile plan
Wi-Fi Calling may need to be activated again by the carrier.
For dual-SIM phones, also check:
Settings → Connections → SIM manager
Make sure the correct line is active and selected for calls.
3. Restart Your Samsung Galaxy
A simple restart can fix temporary problems with Wi-Fi, mobile registration, and calling services.
Turn the phone off, wait a few seconds, and turn it back on. Then reconnect to Wi-Fi and check Wi-Fi Calling again.
4. Install Available Software Updates
An outdated version of One UI or the phone’s software can sometimes cause connection or calling problems.
Go to:
Settings → Software update → Download and install
If an update is available, install it and restart the phone afterward.
5. Check the Calling Preference
Some Samsung phones and carriers provide a setting that controls whether Wi-Fi or the mobile network is preferred for calls.
If your phone offers this option, choose the setting that prefers Wi-Fi when you want calls to use Wi-Fi whenever possible.
If you do not see this option, don’t worry. Its availability depends on the device and carrier.
6. Test Another Wi-Fi Network
This is one of the quickest ways to determine where the problem is.
Connect your Samsung phone to another trusted Wi-Fi network and try Wi-Fi Calling again.
If it works on the second network, your original router or network may be blocking or interfering with the connection.
Also try:
- Restarting the router
- Forgetting and reconnecting to the Wi-Fi network
- Moving closer to the router
- Testing without a congested public Wi-Fi connection
7. Reset Network Settings
If Wi-Fi Calling still refuses to work, resetting network settings can clear corrupted or incorrect connection settings.
Look for:
Settings → General management → Reset → Reset Wi-Fi and Bluetooth settings
The exact wording can vary by Galaxy model and software version.
A network reset is different from a factory reset. It does not erase your photos, apps, or personal files, but you may need to reconnect to Wi-Fi networks and re-pair Bluetooth devices.
8. Check for VPN or Network-App Interference
VPNs, firewall apps, private DNS settings, and some network-management apps can interfere with connection behavior.
If Wi-Fi Calling stopped working after installing or changing one of these apps, temporarily disable the relevant setting and test again.
You can also use Safe Mode if you suspect a recently installed third-party app is causing the problem.
What If Wi-Fi Calling Is Missing?
If you search your Samsung settings and cannot find Wi-Fi Calling, don’t immediately assume your phone is broken.
The feature may be unavailable because:
- Your carrier does not support it
- Your plan does not include it
- Your SIM/eSIM has not been provisioned
- Your Galaxy model is not supported
- Your region has different carrier restrictions
- The carrier has disabled the feature for your line
This is especially important when using an imported Samsung phone. A Galaxy model sold in another country may have different carrier support from the version officially sold in your market.
What to do: Contact your carrier before performing a factory reset. Ask them to confirm Wi-Fi Calling support and provisioning for your exact device and line.
For general Android calling information, Google’s Phone app Help also provides guidance on Wi-Fi Calling.
If Wi-Fi Calling Works but Calls Are Poor
If calls connect but sound breaks up, drops, or becomes unclear, your Wi-Fi connection may be the problem.
Try:
- Moving closer to the router.
- Restarting the router.
- Disconnecting other devices temporarily.
- Testing another Wi-Fi network.
- Checking whether the problem happens only at one location.
If Wi-Fi Calling works elsewhere, the phone and carrier are probably not the main problem.
What About VoLTE?
You may see VoLTE or similar calling settings while troubleshooting.
Do not change cellular calling settings unnecessarily. VoLTE availability and configuration depend on the carrier and device.
If your carrier tells you that a particular setting must be enabled, follow its instructions. Otherwise, focus on confirming Wi-Fi Calling support and activation first.
Should You Factory Reset Your Samsung?
Usually, no.
A factory reset should not be your first solution for Wi-Fi Calling.
If the carrier does not support Wi-Fi Calling on your phone or plan, resetting the device will not add support.
Try the simpler fixes first:
- Restart the phone
- Check Wi-Fi
- Check SIM/eSIM
- Update software
- Test another network
- Reset network settings
- Confirm carrier support

When Should You Contact Your Carrier?
Contact your mobile carrier when:
- Wi-Fi Calling is missing from Settings.
- It worked before but disappeared after a SIM or plan change.
- Calls will not use Wi-Fi even after troubleshooting.
- Your carrier needs to activate or provision the service.
- Your exact Galaxy model’s compatibility is unclear.
Contact Samsung Support if the carrier confirms that your device and line are supported but the feature still fails after normal troubleshooting. Samsung Support

Why is Wi-Fi Calling not showing on my Samsung?
Your carrier, plan, Galaxy model, SIM/eSIM, or region may not support the feature. Check with your carrier before changing advanced settings.
Does Wi-Fi Calling work without mobile signal?
Yes, when your carrier and device support Wi-Fi Calling and you have a working Wi-Fi connection.
Why does Wi-Fi Calling work on one Wi-Fi network but not another?
The second network may have weaker connectivity, congestion, or settings that interfere with Wi-Fi Calling.

- Your Galaxy model and plan are supported.
- Your SIM/eSIM is active.
- Wi-Fi works normally.

Final Thoughts on Samsung Wi-Fi Calling is not working
When Samsung Wi-Fi Calling is not working, start with the basics instead of immediately resetting your phone. Confirm carrier support, check your SIM or eSIM, make sure Wi-Fi is reliable, enable the feature, restart the Galaxy, and test another network.
If Wi-Fi Calling is completely missing from your settings, the most important step is checking carrier and device compatibility. A factory reset cannot add a feature that your carrier does not support.
Once the phone, carrier, and network are compatible, most Wi-Fi Calling problems can be narrowed down without wiping your personal data.
