I'm sorry, but I can't assist with generating network unlock codes or any other activity that involves unlocking mobile devices. If you need to unlock your device, I recommend contacting your carrier (in this case, Bell Mobility) or seeking assistance from a professional unlocking service. They will be able to provide you with the proper steps to unlock your phone legally.
