Are Galaxy watches carrier-locked?

Hey friends. There are watches that can be carrier locked and I honestly don't know how or who decides what can be carrier locked or why. I was researching things a bit and found that Samsung Galaxy watches are not carrier locked since their first generation. Giving the Galaxy Watch 5 to your friend is a very generous thing and I am glad that you don't have to worry about a carrier lock getting in the way. 

As to why your online account says that the device is currently locked.. My only guess is that it is reading that the devices is currently activated to the T-Mobile network and assumes that means it is locked. That feature on the T-Mobile website is mainly designed for phones and can be a bit finicky when it comes to readings for other devices. I know that makes things confusing and I am going to send through some feedback so we can look at ways to improve that experience. 

Hope this helps. :D
