depends on your contract, confirm the details with the place you got it from
Are you paying it in installments? It might be locked until its paid off. Otherwise, fully paid devices are not going to be locked. Note that even tho it might be docomo-locked until paid off, you can still use it with other docomo-based providers like ahamo or any MVNO that uses docomo network.
All new phones sold after October 2021 must by law be sold SIM unlocked, so you should be able to use any network your phone supports.
Most models sold new since around 2016 can be unlocked for free or by paying a small fee.
