help me with xcloud which only crashes on the TV box and does not enter the cell phone

xcloud, generates questions since I understand you do not need a very advanced cell phone to use it, so all you need is a good internet signal and probably a control, so I do not see the case of an ultra-modern or first-class cell phone if one of low or
medium range will give me the same for less price

at this time there is not a wireless headset for the xbox one but curtain wireless headsets in general can or well have a plug in jack which would fit most cell phones and xbox controllers. it's a little box that plugs in to the cell phone or controller
which acts like bluetooth connector to the head phones . but very hard to find might have to check retail stores or order on line .

it seems interesting to be able to use xbox thanks to xcloud without having to buy another device as it happens with nintendo, that is we all have a cell phone and if you have an xbox a control to use, which makes xcloud more interesting than a switch,
but we must consider the quality of the internet and that very possibly affects the quality when it comes to playing, it is certainly the future, but there is a long way to go

I logged into my account on my mobile phone, or you can on PC, and got a verification code sent to my cell via text message and then entered that code in the box on my phone on my account page, then changed my password, and when I logged back in on my Xbox,
everything worked perfect.

I've never heard of it until now... sounds cool.--As long as it is, cool. I have no cell phone. The mobile app games are the only thing I haven't really been able to tap into. It would be great to get a box to finally be able to do that. Or a cell phone.
You kids don't even call em that anymore, do you? Smartphopne? Tablet???
