For the past few years I have always had a iPhone and a Samsung Note. I love being able to take my ATT SIM and swapping it between the two devices. It has never been an issue and always worked without problem. BUT NOW, with my new Apple Series 3 Watch with LTE, I don’t believe I can continue this approach. My understanding of NUMSYNC and how it works...if I change the SIM, and put into back into my Note8, it will break the NUMSYNC setup and my Apple Watch will no longer work when I eventually switch back to the Apple ecosystem.

Anyone have any experience or opinion on this. I really don’t want to try it as it took me 2 1/2 hours to get the Apple Watch setup with ATT.
Thanks
