Regarding the quality of mobile Internet here: I found out yesterday at the AT&T office that I’ve had only 3G since August, not 4G. They offered to upgrade to 4G for an additional 30 bucks, I declined. Everything works fine as it is, both video and audio.
By the way, I now have an iPhone X! Happy after Samsung Note 4, everything is fast and looks great
