Also, it's not just the published rate. They do things like...

- add credit card surcharges

- bill whole minutes

- no refunds for unused minutes when the service isn't needed.

And, it's not just phones. Similar treatment for email/telegram type services, commissary type items, books, music, etc. Some even deduct from these accounts for medical service visits.

The US incarceration system is a shit show.
