WiFi Calling & Text

There’s a great feature available to Ultra Mobile subscribers: WiFi Calling & Text! This allows you to use a WiFi network to make or receive calls and text messages. If you’re ever in an area with unpredictable coverage, like a basement, just connect to the nearest WiFi hotspot and use your Ultra Mobile phone to call or text over WiFi!

As of June 2018, this feature is available on select Android and iPhones. Learn more about WiFi Calling & Text by clicking the “Learn More” button below.
