This July (2021) I purchased a new Apple Watch 6 with a new iPhone SE(2) so both could work together, and allow me to use the independent cellular capacity through the Watch. I have an Xfinity Mobile account. It has now been over two weeks, and STILL Xfinity cannot, for some reason, activate the cellular on the Watch. It has been a nightmare. There is a local Xfinity store where I live, so I drove down there and spent hours with a tech there who, through his direct computer and phone connections with Xfinity "central," still could not get the Watch's cellular to work--to become activated. He advised that I wait and be patient. Right now, I have no confidence that Xfinity will ever get the cellular capacity on the Watch to activate so I can use it as an independent phone. Would switching mobile service to Verizon be a remedy? Or would I repeat this mess at Verizon?
