I was arrested for contempt of cop once, and I had a similar experience. When I tried to call my family, they all told me that they got an automated recording with instructions to create an account and pay for the collect call to a cell phone. While they were trying to navigate this onerous system for the opportunity to pay exorbitant amounts of money to talk to me, I'm sitting in a jail cell wondering if I'm ever going to get a hold of them.
Getting arrested is traumatic enough already, and the assholes trying to wring dollars out of a captive audience make it that much worse. Kudos to the FCC for taking a significant step to remedy the problem.
