I currently have the Gear S2 on AT&T's network (numbersync of course) and I've been waiting for something smaller to come out. I haven't used Apple products in a long time but know their watches have the square or rectangular-faced watches and they look so much more comfortable than these bulky things. I talked to an AT&T rep today and they said that my watch is the SMALLEST that is compatible with numbersync for Android. Is this really the case??? Is there ANYTHING else out there smaller that is compatible even if it's not a Gear??
