T-Mobile Wi-Fi calling is not working? How to fix

Wi-Fi calling has been the most popular feature for smartphone users. It allows you to make phone calls using a Wi-Fi network. Wi-Fi calling is advantageous in that it is simple and convenient. Moreover, it is suitable when the cellular signal strength is weak but the Wi-Fi signal is strong and stable.

There are, however, situations when T-Mobile Wi-Fi may fail to work. It is frustrating since most T-Mobile users depend on Wi-Fi calling for everyday calls.

Here are several reasons why your T-Mobile Wi-Fi is not working and the different methods you can apply to resolve them.

1. Restart your phone

It is commonly advised that you restart your device whenever your phone network is not working. It will help resolve the phone’s temporary glitches and bugs interfering with its system. Below are steps on how to restart an Android phone:

  • Press the Power button until the Power off menu appears on the screen. 
  • Tap on Restart on the Power Off menu.
  • Allow the device to rest for two minutes before turning it on by pressing the Power button. 

Below are steps on how to restart an iOS device: 

  • Press and hold the Volume Up button and the side button simultaneously until the Apple logo appears on the screen.
  • Drag the slider and allow the device to turn off.
  • Wait for two minutes before you can turn on your phone. 
  • Press the side button until the Apple logo appears on the screen.

2. Reinsert the SIM card

Your T-Mobile Wi-Fi calling may also not work because of a temporary glitch on the T-Mobile SIM card. Below is a guide on how to do it correctly:

  • Find the SIM card compartment on either side of your phone.
  • Use a SIM eject pin to remove the SIM card holder. You can use a paperclip or earring stud if you don’t have one.
  • Reinsert the SIM card in its slot and return it to its SIM card compartment. 
  • Turn on your smartphone.

Ensure that you insert the SIM card correctly. If not, the T-Mobile services will stop, and you can damage the SIM slot.

3. Disable airplane mode

When the Airplane mode is enabled, you cannot place Wi-Fi calls nor access any T-Mobile services.

It can also come in handy when resetting the Wi-Fi network by turning it on and off. By doing this, you will force Wi-Fi calling to normal operations.

4. Enable Wi-Fi calling

You cannot place Wi-Fi calls because you have not enabled the Wi-Fi calling feature. You should therefore check if you have turned off the feature in the T-Mobile app using the following steps:

  • Go to the T-Mobile menu.
  • Tap on Settings and select the Wireless and Networks Tab.
  • Tap on the Wi-Fi calling tab.
  • Turn on the toggle next to the Wi-Fi calling tab if it is gray. If it is green, turn it off and then on again at least three times.

5. Check internet connection

A poor network connection is the main reason your T-Mobile Wi-Fi calling is not working. First, ensure that your device is connected to the network. 

If it is connected, but you still cannot place a Wi-Fi call, there is a poor or unstable internet connection. You should contact T-Mobile customer support to help you fix the problem.

6. Reset network settings

Alternatively, you can try resetting your device’s network settings if the T-Mobile Wi-Fi calling isn’t working outside the US. Resetting network settings removes temporary cache files from Wi-Fi connections, Bluetooth, and cellular networks.

Below are steps on how to perform a network reset:

  • Tap on Settings.
  • Tap on General.
  • Select the Reset option.
  • Tap on Reset Network Settings.
  • A pop-up notification will prompt you to enter your password.

Once you have completed the above procedure, wait three minutes before reconnecting your device to the Wi-Fi network. Then, confirm whether you can place a Wi-Fi call and if you still cannot, contact T-Mobile customer support to help you fix the problem.
