Is my Series 3 now locked to AT&T ?

[DotCom2]

I opted in for the 3 month free cell service trial on my Series 3 watch with AT&T and then canceled.
When I go to sell my watch, is it now locked to AT&T?
And if so, how does one go about getting it unlocked so the new buyer can use any cell service they want if they so desire?
TIA

The watch follows whatever phone it's connected to, When I tried the cell service on my S3SBSS, I decided it wasn't worth it, so disconnected, and when I sold it, there was no problem with the cell service for the new buyer.
AT&T gives the watch a different number, and then "call forwards" (easy explination) to the actual phone, so they're tied. When the new buyer opts for cell service, the watch gets a "new number", and the old number is discontinued. Hope that makes sense, it's really pretty easy. Usually, the people at the phone store know how to do this.

Yes, it makes perfect sense.
Thank you.
