Wi-Fi Calling

Wi-Fi calling enables you to make calls, send text messages, and check voicemail on your mobile device over a WiFi network when you’re in an area where cell coverage is weak or not available. All the major carriers (AT&T, Verizon, and T-Mobile) offer Wi-Fi Calling.

With Wi-Fi Calling, your device will only route calls and texts when cellular coverage is limited or unavailable.

You can set up Wi-Fi Calling on a university-owned device or on your personal device. And there’s no charge for using Wi-Fi Calling with your existing phone plan.
