Wi-Fi Calling allows customers to make and receive calls and texts (SMS & MMS) over a Wi-Fi connection. Using Wi-Fi Calling is easy – customers won’t even know they’re making a Wi-Fi call. Simply connect to an available Wi-Fi network with a Wi-Fi Calling enabled smartphone and continue to make a call or send a text as you would over a cellular connection. No separate app, log-in or number is needed.
With next-gen Wi-Fi Calling, T-Mobile is pioneering seamless handover between our LTE network and any available Wi-Fi connection so calls don’t drop between the two. Next-gen Wi-Fi Calling also features HD Voice quality, when calling another HD Voice-capable user. This means our customers can now maintain crystal clear HD Voice calls, whether connected to T-Mobile LTE or Wi-Fi connect – all using their existing T-Mobile number.
