deends on what category prison you are in. there are 5 i think, catA, B,C,D, and open. A is 23 hour lock up with B, C is slightly better where u can do work, education etc, and have more time to make calls etc, D is pretty much like an open prison, the open prison allows you to leave the prison during the day and return at night, and have town visits....Most prison offer inmates work, like in the kitchens, or cleaning etc which allows them to leave thgeir cells during the day, they can then make sneaky fone calls, the guards usually turn a blind eye as they are working.All prison have lock up at 7pm after which time the cells are locked till morning 6am. Hope this helps
