Wi-fi Calling
Your cell phone may use wi-fi for calls and texts when cellular coverage is not available or when you have wi-fi calling turned on. Please note that wi-fi calling doesn't support calls to 211, 311, 511, and 811. If you are calling from wi-fi or a provider that does not support 211, you can reach your local 211 by web chat or dialing the center's 10 digit number.
