Here is a riddle for you: TVs and other non-Xfinity service devices are able to connect to wifi and operate without having a "mobile data" connection (data through Xfinity). Yet, when my wife connects to the wifi on her phone with her mobile data off, she is unable to stream, load a webpage, etc., but when she turns her mobile data on (still connected to the wifi) she is able to stream and all that fun stuff. Why is this?
My understanding is that this device should operate through the use of Wifi, which is provided by Xfinity as well, just as any other device can operate with a Wifi connection. Is there something that I am not understanding or a difference in equipment functionality that I might be overlooking?
