If you go to staff with a problem, the only thing they can do for you is put you in the SHU as a protective custody inmate, and that will cause you trouble throughout your entire incarceration. 1  If you complain to staff, you're stuck out in no-man's-land between the staff and inmates. 2  Neither group will help you.
Definition: A 'locked' mobile phone is one that has been restricted by software so that it can only be used with a single network or carrier. Locked mobile phones are usually GSM phones that use a SIM card-hence the use of the term 'SIM lock'.
An unlocked cell phone is a mobile phone that can be readily used on any GSM network of the owner's choosing without having to commit to a carrier plan of any kind. This means that the owner can slide in a SIM card from any wireless carrier in his or her region to start making calls, surfing the Internet, and benefiting from any of the services available on that carrier's network for its customers.
