The quality of a Wi-Fi phone call is dependent on the strength of the signal and the quality of the Internet router. If the router is older than three years old, your Wi-Fi calling may not have the highest audio quality possible.

When using Wi-Fi calling, it’s important to update your E911 Address inside the MyMetro App. This allows a dispatcher to find you in case of an emergency for which you call 911. Wi-Fi calling won’t work without an E911 Address. Don’t forget to then update the address should you move and use Wi-Fi calling from a different location.

You can also update your E911 Address within My Account.
