how to advise xfinity that I do not have a mobile phone

@XfinityMarcos​ 

I assume so.  I ended up on the homepage of the community forum section.

Did it open a link with the steps on how to manage those details?

I don’t use the app, just the website and I’ve already been to the relevant page.  BUT not allowed to edit the page by not inserting a cell phone number!  Also note that the article that was sent to me dealt with editing email.

OK, I’m just going to forget about this, and just leave the info as it is.  Not important enough to spend any more time on this.
