Note 4 Marshmallow Update Outside of U.S
hello there. My problem is that i live outside of the U.S somewhere in the Carribean. I have a unlocked AT&T Note 4 but i dont have an AT&T sim card. Will i still be able to get the marshmallow update even though i dont have the att active sim card.

Unfortunately, no. At least not through official channels.
There may be forums that cover things like this, but officially, they're not discussed here. Even with these methods however, it's fairly easy to brick a phone, if you're not familiar with the process.
Maybe there's someone you could send it to in the US, to bring by a Best Buy, for a quick flash?
