Can't add my cell phone number to my account. I get a notice saying it is already being used. Help!

Hi @nancieguarrera, 

Thank you for posting your question, and welcome to the Xfinity Forum. I've seen this situation before, where a former customer may have once used a number for an account before. I can help determine if this is the reason you get that error. 

Can you send me a private message? To send a private message, click on my name, "ComcastChe," and then click send a message. Please include your first and last name and address.
