A:AnswerA Samsung email account is not required. Is it possible this comment refers to a version of the watch with a SIM card? I have the Samsung Galaxy watch (46mm) and it does not require Samsung email, it doesn't even require creation of an account on samsung.com (this can be skipped.) This watch has no direct communication capability, it all goes through your cell phone via bluetooth and optionally WiFi. It receives notifications from the cell phone and if a response is sent, it relays it back to the cell phone for sending. Emails and texts are handled identically, your response is relayed back to the cell phone for sending and it can be any email server.
