Bootloader and root topic

Hi guys,

New note 3 user and new to t-mobile.

Perhaps an already answered question, but how exactly do I go about unlocking my bootloader? I want to flash cm11 and twrp. Are the tmobile phones already unlocked?

If the answer to the above is no, what are the steps to get it unlocked and a new recovery installed? Point to a link would be great.

Thanks!
