According to Banner Android 10 beta for Note 10 and Note 10+ so far is only for Samsung Unlocked devices, and not for any Carrier devices. So for Note 10 devices it may only be available for Unlocked devices, as same in last year it was only for Samsung Unlocked devices for Note 9. So it may be Same this year we'll just have to wait for Official confirmation from Samsung. So just keep checking Samsung Members app. Hope that helps.
