Note 2 imei unlock topic

Just wondering if there is an app or a way to unlock this sgh-i317m Canadian variant for free I know a couple years ago I had a Canadian galaxy s vibrant on Rogers I rooted and flashed a ROM and it soft bricked then I searched for the stock ROM for it and found an att ROM but it was sim unlocked for whatever reason is there any note 2 ROMs that are sim or imei unlocked?
