Can a prisoner call me? Prisoners have to submit an application to get all their phone numbers approved by the security team in the prison. The security team then needs to call the numbers to verify, so this usually takes a few days to complete before a prisoner can make outbound calls. Once approved, they can make outbound calls to loved ones, providing they have enough PIN phone credit on their account. The cost of the calls for prisoners is (since Sept 2021): To a landline (weekday) - 3.1 ppm (pence per minute) To a landline (weekend) - 2.75 ppm To a mobile (weekday) - 6.88 ppm To a mobile (weekend) - 4.5 ppm Manage Cookie Preferences
