AT&T Gear S is 4G. I haven't seen an LTE symbol but when I use it for phone calls or data the 4G, not 3G, icon shows up on the screen.
I thought the chip would dictate LTE and I'm not sure the chip in the S supports it .
You're right. I always forget about HSPA+ being called 4G on some GSM networks. I was thinking LTE.
So yeah, no LTE on the Gear S. It's GSM 3G/HSPA+.
