AT&T Unlocked S7 Won't Update

 My Galaxy S7 is on the August update of last year. I've tried taking it to Best Buy to get flashed but they no longer offer that service. It is AT&T unlocked and running on Cricket. Would getting an update be as simple as just inserting an AT&T sim?

you can only update a ATT phone with a ATT sim that is active on a ATT prepaid or postpaid account and connected to wifi.  The active part is the main thing.
