Wi-Fi Calling1 makes it possible to call directly over Wi-Fi and the Internet. It’s the best solution when cellular coverage is weak or not available inside a home or place of business. If Wi-Fi Calling is not an option, you can try AT&T MicrocellTM a signal booster that acts like a mini cellular tower.

You need a compatible device to use Wi-Fi Calling, for a list visit Wi-Fi Calling devices.

Wi-Fi Calling
Wi-Fi Calling provides voice and text service over an active Wi-Fi connection. 
  • You may need sign-in credentials to connect to the Wi-Fi network.
  • Once Wi-Fi Calling is turned on, your device will switch to Wi-Fi when cellular service isn’t available. 
  • Since Wi-Fi is available in many business locations it will expand Wi-Fi Calling coverage. 

AT&T Microcell

An active MicroCell connected to broadband Internet provides a cellular connection in your home.
  • Only devices registered to a MicroCell can access that cellular connection. 
  • When you leave your home, you’ll leave MicroCell coverage. 

Wi-Fi Calling is generally the better option
  • Wi-Fi Calling lets you talk and text from indoor locations where it’s hard even for a strong cellular signal to reach.
  • Wi-Fi Calling enables you to place calls over Wi-Fi when traveling internationally.
  • No additional equipment is necessary.
