So I guess it is possible to have analog AM cell phones operating
between 40 KHz and 285 KHz that are the same small size as today's
cell phones. Right? If it's not possible then why not? If a wrist
watch can do it, then why not a cell phone?

If a wrist watch can to what? Transmit a signal? They don't, they only
receive.
