The utter and abject failure of my encounter with T- Mobile support of the Cellular option provided by Apple Watches.

Here is another update by trying to visit the retail store to fix.  You get long stare and attitude and so much false info.  1.  Reps say you cannot pair more than one phone to a iPhone.  There so many articles on how you can do those.  2.  Apple watches are not made for childs and elderly.  Again, Apples specifically calls out this use case on their website.

At the end of the day TMO retail is horrible and only wants to lie to get you on same plan or device you don't want.
