I have TMobile latest update and this option works fine on my Note 4.I have TMobile. It's not letting me activate it under Settings. See pic.//uploads.tapatalk-cdn.com/20171127/733bdef9705bbffcc5576adaf3ac92be.jpg
Yeah, I hear you. It's weird, mine is not accessible at all.I have TMobile latest update and this option works fine on my Note 4.
