From what I'm hearing you only get the large in the 44 and the small in the 42
I have called Samsung many time the where to send me the large but ended up with the small, called again and the person that I talked to said that I had to buy the large, I have not been able to find were I can get it at. I think it is wrong they make the mistake and I'm the one that has to pay for it and the Samsung told me that there is no way to tell the size on the bands anyways so I'm just stuck with what I have.
If you have a very small wrist such as 5 & a half inches around I recommend the 40mm. My wrist is 5 and a half inches around and my Galaxy Watch active 2 doesn't stay on top of my wrist. I can't afford another band right now. I'll have wait. I love this watch. Finally Samsung brought out a smaller watch👍. What Samsung needs to do now is add 3 more holes too the small bands. This will solve the fitting issues. I'm in no way giving up my active 2. This is the Perfect Samsung Galaxy watch 👍. The LTE has a really nice leather band. The only thing that needs to too change is, 12 or 13 holes instead 10.
