Why Is My T-Mobile WiFi Calling Not Working?

We’ll inspect your connection thoroughly in our solutions, but first, let’s take a look at what else might have gone wrong:

1. Device Failure

Potential smartphone WiFi failure might prevent you from using the online WiFi calling feature of T-Mobile.

2. Network Settings Problem

An issue with the network settings could suppress the Wi-Fi calling feature.

3. Toggled Feature

4. Airplane Mode

Users often flip the airplane mode on, which will actively prevent any WiFi usage, including the T-Mobile WiFi calling.

Lastly, an internet connection issue will also prevent you from using any online services including the T-Mobile WiFi calling.

There are even more possibilities that we’ve included a solution for, so make sure not to skip any of the upcoming fix methods.

How To Fix WiFi Calling Not Working T Mobile?

Before we proceed any further, we recommend rebooting the smartphone you’re using to perform WiFi calls.

This will actively discharge your device, which might resolve any issue related to temporary OS glitches.

If that didn’t work and you still cannot perform WiFi calls, here are some easy solutions you can apply to fix the issue:

Solution #1 Re-Insert The SIM Card

If you cannot perform a WiFi call with T-Mobile, it could be due to a temporal glitch with your SIM card.

This is why the first solution we recommend is re-inserting your SIM card.

Follow these steps below to do it right:

1. Locate the SIM card compartment on one of the side panels on your phone.
2. Use a paperclip or the SIM instrument to eject the SIM card holder.
3. Re-Insert the SIM card into the compartment and put it back into your phone.

Beware of the SIM card positioning within the compartment since your phone might be unable to scan it correctly.

If not inserted properly all T-Mobile services will be disabled and you can damage the physical cardholder.

Solution #2 Set Up WiFi Calling Again

It is possible that you’ve accidentally disabled the WiFi calling as a result of a factory reset and you will have to re-enable the feature again.

Follow the steps down below to set up WiFi calling properly:

1. Go to your T-Mobile menu.
2. Tap on Settings and head to the Wireless & Networks tab.
3. Click on the WiFi Calling tab.
4. Select the WiFi calling feature by tapping it once.

If the slider turns green, then the feature is successfully enabled and ready to go. If it is enabled, make sure to toggle it OFF and ON again.

Solution #3 Troubleshoot Internet Connection

Another major cause that can be disrupting T-Mobile WiFi calls is the missing internet connection. This can often occur whenever there is an internet outage or ISP maintenance.

Following the bullets below you’ll make sure that the problem is not on your side:

Hard Reset Router

Unplug the router’s power adapter and wait for 5 minutes. Then plug the power adapter back in and turn on the device.

Check Cable Connections

Ensure all cable connections are positioned correctly and plugged tightly in their respective ports. Check for visual hardware damage and if possible, replace any suspects.

Relocate Device

Position yourself as well as the smartphone closer to the router to get a better connection during the upcoming solutions.

Once you’re done with these steps, restart your smartphone and try conducting a WiFi call. If it does not work, jump to the next solution.

Solution #4 Connect to A Different WiFi Frequency

It is possible that the network WiFi frequency your smartphone is connected to is not reliable due to internet connection failures.

If you have recently changed the router or its settings the new WiFi might not be reachable by your phone.

To set up a new WiFI frequency you will have to access the router settings.

How To Access the Router Settings?

1. Connect a Windows PC/laptop to the WiFi.
2. Open the Command Prompt (CMD) as administrator.
3. Write: “ipconfig” and hit Enter.
4. Copy the router IPv4 and paste it down into your web browser.
5. Use admin/password for login credentials to enter.

Once you’re in, you should head to the Network tab and find the WiFi settings. If you’re using 2.4Ghz, set up the 5Ghz network.

From there you will be able to set up an individual WiFi connection that will soon appear in the WiFi list of your phone. Connect to the new set WiFi and test out the T-Mobile WiFi calling now.

Solution #5 Disable Power Saver/Airplane Modes

If your T-Mobile WiFi calling not working even after all previous solutions, then you might have accidentally enabled any power saver modes or the airplane mode on your smartphone.

You will have to immediately disable them since this can be interfering with your phone’s WiFi connectivity.

In addition, you can delete any applications draining your internet bandwidth.

Such applications could be updating, uploading, or seeding. Also, check and disable any VPN services that are currently active on any device connected to the WiFi you’re using for the T-Mobile calling.

Solution #6 Reset Network Settings

Another thing you can try is to reset the network settings on your phone.

This will erase the cache of any WiFi connections, Bluetooth, and cellular data that are temporarily stored on your phone.

To perform a network reset, follow these steps:

1. Go to your phone’s menu settings.
2. Head into “General” and locate the Reset tab.
3. Click on “Reset network settings”.
4. Confirm the pop-up window with your password if it’s required.

Now wait for several minutes and reconnect your phone with the WiFi.

Then try out the T-Mobile WiFi calling and if it works, then the issue is solved. If it doesn’t, let’s take a look at what options you’ve got left.
