T Mobile (US) emailed AND texted a warning and instructions to all customers who bought a Note 7 right after Samsung decided to recall the device. I still use mine, though, because this thing is the shit and I’m not giving it back until they send me a new one. Also, I don’t have any kids.

No clue. But that would be more of a carrier thing as opposed to it being Samsung. The most samsung could do is ask.

Didn’t a SMS get sent to all Notes about the recall?

True I just would assume an early adopter/ person who buys a new phone the moment it comes out, would be more in touch to the news.
