Samsung is at the forefront of developing powerful devices, and Samsung S9 and Samsung S9+ are not exceptions. These new flagship devices from the Samsung line were released a couple of months agond their impressive hardware took the Android world by storm.
Here we’ll discuss several ways to fix Galaxy S9 Wi-Fi calling issues. These methods have been used by other users before and have been proven to fix these calling problems.
How to Fix Galaxy S9 Wi-Fi Calling Issues
Making and receiving calls is one of the most basic functions of a phone. If your device can’t make or receive calls, then what’s the point of having it in the first place? This major problem was noticed by Samsung users after they had installed the latest Android updates.
Check out these DIY methods to fix Galaxy S9 Wi-Fi calling issues every affected Samsung user should try before calling in for help.
Method 1: Switch to Wi-Fi Calling as Your Default
Whenever you walk into a zone where a Wi-Fi connection that you’ve connected to before is available—whether it’s your home or office, your device should automatically connect to it. Every smartphone, regardless if it’s an Android or iOS device, is designed to automatically switch to a 4G or Wi-Fi connection based on the availability of the network. So when your phone doesn’t automatically connect to your work or home Wi-Fi, then there’s something wrong with it. If this is the case, you can then force your device not to use mobile data, especially if you spend most of your time within a zone with an available Wi-Fi connection.
To turn on Wi-Fi calling as your default call option, follow these steps:
- Go to your Galaxy S9 phone’s Settings, then turn on your Wi-Fi connection once.
- Press the home button to get back to your home screen.
- Go to Settings again and switch off Wi-Fi. You can also swipe down from the top of your screen to open Quick Access, where you’ll find the Wi-Fi icon. You can tap the icon to quickly turn on or off your wireless connection.
- Go to Settings > More connection settings.
- Tap Wi-Fi Calling, then choose Wi-Fi preferred.
This should force your device to use Wi-Fi whenever a wireless network is available. If this doesn’t work, turn on Never Use Cellular Network.
Method 2: Reboot Your Device and Eject Your SIM Card
There are a lot of common Android problems that can be fixed by a simple reboot. Restarting your device is one of the ways to fix Galaxy S9 Wi-Fi calling issues, but you need to perform some extra steps to totally solve the problem.
Here’s what you need to do:
- Do not restart your phone. Just switch it off by holding the power button.
- Once the device is completely turned off, eject your SIM card, using a SIM ejector pin.
- Clean your SIM card by wiping it with a soft cloth or tissue. Do not use wet cloth or other materials to clean your SIM card.
- Turn on your device without the SIM card.
- Go to Settings and turn off Wi-Fi Calling.
- Turn off your device once again.
- Insert your SIM card into the slot and turn on your device.
This method should clear all the cache on your Android device and fix your calling issue. Another way to completely clear your cache without restarting your device is by using Android cleaning tool. Just run the app, and it will automatically scan and delete your Android’s cache and junk files.
Method 3: Check Your Router’s Distance and Minimize Signal Obstructions
When you’re connected to a wireless network, distance is not something that you consciously think about. But when you’re on a call, it is very difficult to notice that you are actually walking farther and farther away from your router, which affects the quality of the call. Mobile phones and other devices will only work up to a certain distance, and the farther you get away from your router, the poorer the signal will be. Hence, the call dropping issue appears.
Another factor that could affect the quality of your call is the number of obstructions your Wi-Fi signal has to go through. Thick walls and big furniture can get in the way of your wireless connection and lead to poor signal.
Here are some tips on how to find out whether your router needs replacement or you just need to move closer to it to get a better signal:
- Use a different device and stay in the same spot to check if the problem is with your device or the router. If the issue remains consistent even with a different device, then your router has a problem. But if you’re able to make calls with a new phone while standing in the same location, then you might need to have your phone checked.
- Upgrade your router so you have better reception inside and outside the house.
- If you see obstacles, like walls, cabinets or furniture, blocking your Wi-Fi signal, relocate your router to an open space.
- Download any system update rolled out, both for your smartphone and router device.
Method 4: Restart Your Router or Modem
If you’re experiencing Wi-Fi calling issues on your Samsung Galaxy S9, as well as your other devices, then you probably need to reboot your modem or router. Before you do this, confirm with your ISP provider that there are no connection problems or server upgrades being undertaken by them that might be affecting your connection. If there are no issues with your ISP, but you’re still stuck with Wi-Fi calling issues, restarting your device will most likely solve your problem.
To restart your modem or router, follow these steps:
- Check all the wires connected to your router or modem and make sure they all fit perfectly. Check also for frayed cords.
- Press the power button to turn off the device.
- Unplug the device to do a hard reset. This will also allow your updates to be applied, if you’ve installed any.
- Wait for at least 10 seconds or up to one minute, then switch on the device by pressing on the power button again.
- Wait for the router to light up, which means your Wi-Fi connection is up again.
If you want to check if this method has solved your Wi-Fi calling issue, try making a Wi-Fi call, using your device.
Method 5: Switch to Airplane Mode
If you’re not comfortable with turning off your phone for some reason or another, you can switch to airplane mode instead to prevent it from switching back and forth between Wi-Fi and cellular networks. Once you’ve switched to airplane mode, you can then configure it to connect only to wireless networks and fix Galaxy S9 Wi-Fi calling issues.
To turn on airplane mode, follow these steps:
- Swipe down your notification tray until you see the Airplane Mode icon.
- Tap on the Airplane Mode icon to activate it. All connections will be blocked.
- Turn on your Wi-Fi by tapping its icon. You will then be connected to your home or office network.
Once you’ve connected to a Wi-Fi network, try making a call to check if the problem has been fixed.
Method 6: Remove All Saved Wi-Fi Networks on Your Device
One of the easiest ways to fix Galaxy S9 Wi-Fi calling issues is by removing all saved networks on your device. This is true for both newly purchased or long-lived Galaxy S9. It is possible that some random Wi-Fi network you’ve connected to before might be causing the problem.
To clear all saved Wi-Fi networks on your phone, do the following:
- Go to your phone’s Settings
- Scroll down and tap Connections.
- Tap on Wi-Fi.
- You will see a list of all the Wi-Fi networks you have connected to before.
- Tap each Wi-Fi network one by one, then choose Forget to remove it from your list.
Once you’ve cleared all the Wi-Fi networks on your device, it is time to add back your home or office wireless network.
- Go to Settings > Connections.
- Tap on Wi-Fi settings. Your phone will automatically search for all available connections.
- Choose your home/office network or tap More to add a new Wi-Fi network.
- Type in your password to connect.
Method 7: Reset Network Settings
When you activate your Galaxy S9 for the first time, you should have a couple of network settings provided by your carrier for the initial setup. Some of these network settings receive updates while others don’t, and some files can get corrupted over time. When these things happen, you get a bug or a faulty setting that could interrupt your wireless connections. Resetting your network settings allows you to download and install a fresh copy of these settings. These new settings will overwrite the old ones and fix any issues associated with them.
To reset your network settings, follow these instructions:
- Go to your Galaxy S9’s Settings
- Choose General Management.
- Scroll down and tap Reset > Reset Network Settings.
- You might be asked to confirm the action through fingerprint scanning or pattern recognition.
Once you have confirmed the reset, a new batch of network settings will be downloaded to your device and hopefully fix your Wi-Fi problems.
Method 8: Enable Wi-Fi Calling for Home
This method suggested by a Reddit user involves enabling the Wi-Fi calling feature for your home network. Take note, however, that this option may not be available for all other devices.
To enable Wi-Fi Calling, do the following:
- Open your Galaxy S9’s Settings, then tap Calling Plus.
- Tap Wi-Fi Calling > Wi-Fi Calling Networks.
- Check if your home or office network is enabled. If it is disabled, it could be the reason why you’re having problems making voice calls.

And if all else fails, you can do a factory reset of your Samsung Galaxy S9 as a last resort. Resetting your device will delete all your data, so make sure everything is backed up before you do this.
