Wi-Fi Calling is an enhanced calling feature, which allows you to make and receive HD voice calls, send/receive texts and pictures (MMS) using a Wi-Fi connection rather than a cellular connection.

Think of Wi-Fi Calling as a backup option when your cellular coverage is less than perfect. For example, inside buildings and basements that have Wi-Fi service, but cellular signal is weak or unavailable. Once you enable this feature, your phone will automatically switch to Wi-Fi Calling under these circumstances.

• Make or receive phone calls through a Wi-Fi connection when there is little or no cellular coverage.
• Wi-Fi Calling offers great value at no extra monthly charge. Calls, texts and picture messages simply apply toward your monthly price plan.
• Wi-Fi Calling can be used in the United States and from international countries* when calling U.S. phone numbers.
• Calls to international numbers are billed in accordance with your international rate plan. (uscellular.com/plans/international-global-roaming)
