I have had my watch since last Friday. Without going into details ( see my prior post), I had done everything right but was getting stuck in a loop in the iWatch app on my phone to activate the $10 per month. I was all set to go to the Att corporate store today, when low and behold ... it went through all the way in my phone. I then received email from att with my new number. I checked the LTE by turning my phone off and making a call and sending a text and it worked great!!! I really love this S3LTE edition of the watch!!!! I have had the two previous editions. One really cool unexpected thing is that the watch unlocks my MacBook Pro with the new operating system!!!! So cool!!!! So don’t give up hope if you are stuck like I was.
