information on changing service provider on iPad.

Presently we have lots of devices and services xfinity has to offer.  We would like information on possibly having my new Ipad pro (2020) enjoy the xfinity YFi connection rather than AT and T.  We were not sure if you had plans available.    We as stated earlier, have mobile devices that have been using the services for years with AT and T and consequently have been paying high costs.   

  We would appreciate your prompt answer to this question.  Thank you for providing the wonderful internet service, TV, home security, phone to us for years.

Sincerely,

Gail Bass
