What happens when a inmate get in trouble/cell phone wise??

No good! Cell phones in prison or jail is a new charge, a felony thanks to the Obama Administration. If they are in federal, the punishment is probably 6-12 months in the SHU (disciplinary segregation), no phone privileges, no visitation, no commissary and at the end of the SHU stay, they will be shipped to a higher security facility most likely hundreds of miles away from the nearest family member to add another hardship to the folks that care about them on the outside. I'm not sure about the state penalties, but the feds HATE the inmates having cell phones.
