Not OP, but I spent 11 months technically in US Federal custody, but in practice I was incarcerated in various county jails [0] that they contract with. I have experience with PayTel and Securus. At the facilities I housed in the digital > printed letter systems were not offered [1], everything was through USPS or your standard parcel carriers for packages. Books from outside were allowed. Global Tel Link, Securus, and PayTel have a very literal captive customer base when it comes to phone communications. While almost everyone wrote letters, a phone call is a much different form of communication. You can actually have a live conversation with a loved one! You can hear their voice, and respond in real time. For this reason, we paid the price demanded by the companies. In my state of North Carolina, the maximum price of a local call through PayTel was $.40/minute. The long-distance rates were cheaper, and so people would get Google voice numbers to get the cheaper rate. [0] Wake County Detention Center, Edgecombe County Jail, and Albemarle District Jail. [1] I could absolutely see these systems being utilized. They could take the roundtrip latency of text-based communication down to a day if the facility had a kiosk from which we could send replies. I was told by people on the yard that this is how CorrLinks works.
