Is T-Mobile Wi-Fi Calling not working on your Android and iPhone? If you’re having trouble making calls over a Wi-Fi connection, there could be a few things wrong. We’ll walk you through the steps to troubleshoot this issue.

What is Wi-Fi calling?

Wi-Fi calling is a feature that allows you to make and receive calls over a Wi-Fi network instead of your cellular network.

This can be useful in areas with poor cellular reception, or when you are indoors and your phone cannot connect to a cellular tower.

Wi-Fi calling works by using your phone’s internet connection to make and receive calls.

When you make a Wi-Fi call, your phone will first connect to a Wi-Fi network.

Then, it will use that Wi-Fi connection to connect to your carrier’s network. The call will then be routed through your carrier’s network as if you were making a regular cellular call.

Wi-Fi calling is a free feature that is offered by most major carriers. To use Wi-Fi calling, you must have a compatible phone and be connected to a Wi-Fi network.
