I am on AT&T, leeneia, but phones at the AT&T store are not unlocked and ultimately cost much more than some unlocked phones that are of very good quality. My wife says the "easy mode" on my Samsung Galaxy J3 makes it look like an "old lady's phone* - which, she says, is just what she needs.
Problem solved. Next time BestBuy has the phone on sale for $129, I'll buy one.
